Ultrasound

What is Ultrasound?

Ultrasound is an oscillating sound pressure wave with a frequency greater than the upper limit of the human hearing range. Ultrasound is thus not separated from 'normal' (audible) sound by differences in physical properties, only by the fact that humans cannot hear it. Although this limit varies from person to person, it is approximately 20 kilohertz (20,000 hertz) in healthy, young adults. Ultrasound devices operate with frequencies from 20 kHz up to several gigahertz.

Ultrasound is used in many different fields. Ultrasonic devices are used to detect objects and measure distances. Ultrasonic imaging (sonography) is used in both veterinary medicine and human medicine. In the nondestructive testing of products and structures, ultrasound is used to detect invisible flaws. Industrially, ultrasound is used for cleaning and for mixing, and to accelerate chemical processes. Animals such as bats and porpoises use ultrasound for locating prey and obstacles.

Ultrasonics is the application of ultrasound. Ultrasound can be used for medical imaging, detection, measurement and cleaning. At higher power levels, ultrasonics is useful for changing the chemical properties of substances.

Hello, I just find out that I might have an endometrial polyp after an ultrasound , I had heavy period for 5weeks it's just stop 2 days ago. I've been advised by the radiologist to do another ultrasound on the 5th day of my cycle. I would like to know that am only 30(just turned) and will that create a problem when conceiving?

Hi
The polyp itself wont create any problem in conception.But you should get it removed surgically if there is heavy bleeding.Repeat the ultrasound as advised.If you have heavy periods again,you need medication to stop the bleeding and also surgical advice.

I had a missed miscarriage on Monday morning in the early a.m. I was 8 weeks along but the sac was only measuring 6 weeks. I passed some tissue and a few clots but have not really had a lot of bleeding . I had a transvaginal ultrasound yesterday and they said my uterus looked empty. I have had to take very little medicine for pain until tonight. I am having sharp pains in my back left side for over an hour now. I took 800 mg of ibuprofin an hour ago and am still having pains. They re bearable but I can t go to sleep like this. Is this normal?

doctor1 MD

Hello, I would be happy to help you.

First of all, it sounds like you miscarried completely based solely on the ultrasound which showed nothing in the uterus. While I might have expected more bleeding than you describe, this must have been the entire pregnancy.

On the other hand, if someone gave...

Hi, I am currently 29 weeks pregnant and I have had a significant decrease in fetal movement over the last week. I was concerned and went in last week for a NST and her heart rate was good. They did a quick ultrasound and noticed a couple things that they were concerned about and scheduled me for another, more in depth ultrasound in a couple days. They had mentioned pelvic inflamation, something about one of her kidneys and her growth was off but they didn t want to go into many other details until they had more information from the next ultrasound. Now, she is still very still but I feel her move about 1 to 4 times and hour and I am experiencing mucus like stools. The mucus is definately from my stools and not vaginal discharge . With her continued decreased movement and now the change in stools, I m not sure what to do. Do I have a need to be concerned or are these normal at this stage in the pregnancy?

doctor1 MD

Hi,
Mucus in the stools is not related to pregnancy, it is related to irritability of the bowels either due to hormonal changes or infection. Fetal biophysical profile done during an ultrasound and fetal cardiotocography to monitor the fetal heart rate are two of the very good methods available...

I ve been experiencing abdominal pain (upper and lower) on and off for the last year. I ve had an ultrasound and the doctor has ruled out a hernia . last weekend, I noticed a lump about two inches above my belly button. It is causing discomfort, especially when I sit for a long time. It is causing some mild pain and feels like it is pressing on something and causing indigestion. Any idea what it could be?

doctor1 MD

Hello.
Thanks for using HCM.
Ruling out hernia and diagnosing it on ultrasound can be quite challenging and depends on expertise of the concerned doctor. Having said this, it can be possible that the time when you had the ultrasound, the hernia could have been small enough to be detected on the...

I was thinking that I was pregnant a few weeks ago n I took a hpt which came back negative so that was a relief. I later started having light stomack pains so I went to the doctor. My Obgyn gave me a urine test (negative) then he sent me to get a vaginal ultrasound to see why I was having slight pain. The ultrasound seen a cyst on my ovary . I started to have sore breast/weight gain/stay tired. I wanted to know is there any chance the doctor could have mistaken that cyst for a baby... Or was he even looking for a baby since my urine test was negative. At the time of the ultrasound I would have been 5 or 6 weeks if I am pregnant. HELP

doctor1 MD

Hello and welcome,

I understand your concern. I cannot comment on what the doctor has seen unless the films of ultrasound are available. However ovarian cysts are known to cause delayed periods. Hence your symptoms are not unusual. A negative pregnancy test and non visualisation of baby both...

Hi, I have a dilemma because a female claims she ended her period on July 13, 2010 (not sure if that’s true or not). We met for the first time and had sex on July 14, 2010 and many days after. On July 27, 2010 she got a blood test at the doctors and it said she was pregnant and the hcg level was at 27. Im not sure what she told the doctors and if that played a part in the due date or if its based off of ultrasounds and hormone levels but the due date given was April 25, 2011 by her doctor. A due date of April 15, 2011 was given based on a couple unexpected trips to the hospital for spotting. They checked her hormone levels and did measurements of the sac by transvaginal ultrasound at the hospital on Aug. 24, 2010. At the hospital they couldn't see the baby until the following week but tried measuring the sac and said she was approximately 5 weeks and 1 day based on what they could gather and see. She was having sex with multiple guys around the same time period for a while now. When would she have most likely gotten pregnant? Is finding out she’s pregnant within 13 days after having sex and having the hcg level at 27 likely? How soon can you find out you're pregnant by blood tests after having sex? How far along could she have been at the point she found out she was pregnant? How accurate is the due date based on the size of the baby by the ultrasound? How much could false information she’s giving them affect the due date? Also is it possible they couldn’t see the baby if she was more than 5 weeks pregnant (perhaps 7 or 8 weeks)? She’s very dishonest and a habitual liar and I am very stressed and don't want to wait months hoping it's not mine but not knowing. Based on all the facts given and the due date given by her doctor based on the ultrasound pics, what conclusion or opinion do you have on what’s going on and what I should think?

doctor1 MD

Hallow Dear,

I have gone through your complete history. Let me answer your questions one by one:

1. If she had her menses on July 13 and if you had a solitary intercourse on July 14, it is most unlikely that this intercourse has caused the pregnancy. The egg release takes place 14 days before the...

Hi doctor, I got my ultrasound done today. I am about 8 weeks pregnant. My last LMP was 7/5/2013. The ultrasound has not detected any cardiac activity. This was the first ultrasound I go for today. There was no free fluid as written by doctor and poor decidual reaction. She told me a missed abortion. I do not have any bleeding or any discomfort. Should I go for a second ultrasound somewhere else?
YYYY@YYYY

doctor1 MD

Hello,

Usually, fetal cardiac activity is seen around 7-8 weeks through abdominal USG. With TVS scan, it is obtained around 6-7 weeks.

Sometimes, in late pregnancy, it can be obtained around 8-9 weeks. So you can undergo one TVS scan after 1 wk for detailed picture. Otherwise, it may turn into...

I have been suffering from the same problem now for 10 months and the symptoms are slowly getting worse. Every day I bloat (massively so that I have to undo my trousers, cant sit down at work etc) and it isn t food related as I tried not eating anything at all and it still happened. I have a constant niggling pain in the left hand side of my belly button that gets worse when I m bloated. I seem to have a mixture of constipation and diarrhea because I go to the toilet once a day but the only way I can describe it is that lots of feces is being held back and only a small bit of what s in there is being released! When I bloat up, I have bad wind too which also makes me think this. After I have been to the toilet the first time (usually always in the morning) I can t go again for the rest of the day no matter how much it feels like I need to to relieve my stomach pains and bloating. When I do go, the stools are very thin and come out easily in lots of little stools rather than one regular sized stool! I keep hearing funny noises coming from my stomach like a clicking sucking type noise and when I have been to the toilet or eaten, the noises are louder and more frequent. The only way to describe the constant feeling is that my stomach is too cramped inside and there isn t enough room for everything! It seems to be getting worse as I am now waking up bloated and in pain - feel very sluggish all the time and have no energy to do anything at all. Even though I have at least 8 hours sleep per night and don t drink alcohol etc before bed, I wake up feeling very hungover and that I just need to go back to sleep. The pain in my left hand side is worsening too - when I touch that now when I m bloated, it feels like a big bruise. Also I have noticed that the less I eat or the more I go to the toilet, the bloating seems to stay the same but the pain in my side is a lot worse. I have had blood tests, stool tests and I have no food allergies of any kind or intolerances. I have had tablets for IBS, which didn t help at all and if anything the pain in my stomach was a bit worse on them. I recently went for an ultrasound scan which they said was clear. For about 4 years, I have also been suffering from bleeding and brown discharge in between my periods but it happens every month. I had a smear and swab for this which was normal so I dont know if that could be related or not. Any advice would be appreciated as I feel that my life is turning so miserable I m always in a bad mood over this and feel angry with everyone all the time! The doctor doesn t know what to make of me but I m worried it will be something serious that is going unfound and that it is only getting worse. Thanks for your help and please ask if you need to know any further info.

I ve had persistent abdominal pain since Mid July. It started quite suddenly with an event/attack severe enough to cause me to end up on the floor, I may have passed out I don t know. I just remember my husband finding me on the floor curled up in the fetal position, and having super severe abdominal pain. The pain passed after 20 mins or so, felt like forever, and I thought all was good, but I was wrong. I began to have intermittent mild attacks, all in the same spot of my Right upper quadrant with nausea/vomiting, and over the course of the next 2 weeks they increased in severity until I couldn t stand it anymore and went to Urgent Care (I am still waiting to establish care with a new Primary care provider), I was diagnosed with a UTI, possible kidney infection and prescribed antibiotics. Ten days later I finish my antibiotics, and all is seeming somewhat better. I m still having mild pain, but not too bad, then about 4 days later, boom, back to square one and urgent care. Now they are thinking it is my gallbladder. I m scheduled for an abdominal ultrasound (external & internal), the day after I see the Dr. in urgent care, I m at work and in so much pain that the urgent care nurse sends me to the ER. They do the ultra sound there, can t find a thing wrong. Everything looks normal. I m given a shot of Toradol and sent home with a referall to a Gastroenterologist. I get a call, and am scheduled for a HIDA scan prior to seeing the GI Dr. My HIDA scan is normal (90th Percentile), although about 3 min after I am given the CCK, I have a severe attack of pain. I wait a month to see the GI Dr. Three weeks prior to my appt with the GI Dr., I start to have more pain, increased nausea, and severe constipation. I m prescribed Zofran for the nausea, to be taken every 8 hrs, which seemed to help some with the nausea. Two weeks prior to the appointment I start having trace amts of blood and mucus in my stool, and am told to monitor it, if it gets to be more than a tablespoon go to ER, otherwise wait to see the GI dr. Finally get to see the GI dr, he pushes on my stomach a little bit after taking a history. He seems puzzled by my sensativity and orders the Colonoscopy and EGD. Yesterday was my colonoscopy and EGD, and the prep for the colonoscopy kicked my butt. I will NEVER take the Nulytely solution again. I probably only kept half of it down, didn t get any sleep the night before due to constant vomiting & diarreah. The day of the test wasn t so bad just prior, but coming out of the ansethesia was not very fun. I was having super severe gas pains, and having a hard time releasing the gas, infact I m still having gas issues 32 hrs later. Yesterday, as I m lying in the recovery area, fighting to come out of the anesthesia, having a hard time of it, my first clear memory is of him grousing about wanting to leave, that he was sick of waiting. I really shouldn t have left, but he talked the nurse into it, and me as well. It s done and there s nothing I can do about it now, except remember not to ask him next time, but call my Mom or Sister. (Pity party whine vent over). They took several biopsies from my esophogas, stomach, and duodenum, but they all came back non-remarkable, and benign. So now the next step is an Upper GI series (X-ray/flouroscopy). Hopefully this test will yield some information and help my Dr. come up with a diagnosis. I was sent home from work early today because I just about passed out, and the Dr that cleared me to drive myself home said I don t belong at work for atleast today and tomorrow. Possibly longer depending on if I can get the nausea under control enough to eat & drink (I haven t had anything but a few sips since I did the prep on sunday). At this point, I m not sure where to go, or what might be going on. I m sick of being sick, and am getting scared it might cost me my job.

Hi my name is Katie, and I’m looking for answers. Any help would be greatly appreciated. I’m a 26 year old, mother of three under three. I was a healthy active mom until I had my third child. After I had had my wonderful little boy I Started to noticed changes in my bowels. Almost every month I would have episodes of extreme abdomen pain with dierhea. By the time my son was two months old I decided to get it checked. It turned out I had a bladder infection. The following month things got worse; yet again I had a bladder infection, only this time the dierhea got a lot worse. I was going to the bathroom 20 plus times a day and had blood in each bowel movement, after three days of this I went to the ER were they suspected I had colitis of the bowel. They sent a referral to a gastrologist, Which I see as of May 9, 2011.The next day the abdominal pain got so bad I had made an appointment with my family doctor, where I got a prescription Asacol 400 mg. After a day on the medication the dierhea slowed down. I thought I was in the clear. I knew what was wrong and felt better. That was until I developed a temp of 107 with lower back pain that night. Went back to the ER to find out I had no colitis of the bowels, but did have a bowel infection. I was sent home with antibiotics. My son is now 5 months old and my health just keeps failing. I’m not eating good, yet not losing weight, no period, and not pregnant. As of four days ago I started to develop severe joint pain with swelling and no redness, for no reason. First day my left hand, that night my left foot, next day was by far the worst, when the pain moved into my right knee, making it impossible to walk. I could not bend the leg at all. By day three back into the ER I go. Was positive for a d-dimer, but the ultrasound found no clots. All other routine blood work was ok. As of today the pain has faded a bit in the joints I have stated about, however has moved into my left shoulder and left knee. I’m on large amount on pain and anti-inflammatory medications. Still no answers. I know I’m becoming extremely frustrated and depressed. I’m so tired of being sick. Please if you know anything let me know. Sincerely, Katie
