What is MRI?
Magnetic resonance imaging (MRI), nuclear magnetic resonance imaging (NMRI), or magnetic resonance tomography (MRT) is a medical imaging technique used in radiology to investigate the anatomy and physiology of the body in both health and disease. MRI scanners use magnetic fields and radio waves to form images of the body. The technique is widely used in hospitals for medical diagnosis, staging of disease and for follow-up without exposure to ionizing radiation.

My 20 yr. old son had a mri done with contrast. When I viewed a side view I noticed a black round spot on the back of his head above the brain stem. Can you give me any indication as to what this may show? It looks like there should be a noticeable lump protruding from the back of his head, although this is not the case. Any info would be appreciated.
MD Hello,
The reporting of MRI involves viewing images aquired in various planes (vertical, horizontal etc), with various settings (T1, T2 etc). The appearance of same structure may vary greatly in different sequences (like white vs black). So it may be difficult to comment on the MRI from the...
I am having an MRI of my head and neck next week. I am a diabetic. I read that the the chances of damage to my kidneys are higher being a diabetic. Also I have dizzy spells and they may get worse after an MRI. Last I have a big lump on the back of my neck. I read it may get larger after an MRI. The dr. that order the MRI is aware of these things. Need some answers Thank you
MD Hi, welcome to our site. I am Dr Saumya Mittal.
Read your query. That is a very significant question and i appreciate your problem. I will try my best to answer your query
First, it is not like MRI is going to increase the size of your lump. There is no valid explanation behind that and this is...
I just had an MRI done on my right clavicle and I m sitting here looking at the images, but I have no idea what I m looking at. I have a large lump on my R clavicle (about 4 x2 ), it s solid and feels like it could be a bone. It does not hurt. An xray showed that it was soft tissue swelling so my Dr sent me for an MRI. After the MRI the nurse gave me a disk just in case I need to see a specialist. I have gotten an MRI before, and that did not happen. So... I m sure my Dr will call me tomorrow, but in the mean time, I m losing my mind. I dont know how many more times I can go through these images, comparing them to google... so... my question for you is,,, Should I be worried? The MRI shows a large black spot over the area.
MD HI
Thank for asking to HCM
I really appreciate your concern, you have not given complete detail of the swelling like since how long it is being there does it have any clinical complain your age and gender are also not given, these are the important detain should have been given here without these...
I m 24 y/o and I d like to understand my MRI report of my brain as it below technique = Axial T1, T2,Flair = Coronal T2 = Sagittal t1 findings - Normal ventricular system shape and configuration with well maintained basal CSF cisterns -well maintained normal grey / white interface, with no MRI abnormal white matter signal. -no MRI evidence of focal ischaemic insult or heamorrhagic vascular accidents. -no sizable intra or extracranial masses or collections. -normal posterior fossa structures. -clear scanned paranasal sinuses . Opinion -grossly unremarkable MRI study of the brain.
MD Hi, welcome to HCM
T1, T2 and flair are sequences taken in MRI, it is technical language.
Your MRI scan is absolutely normal. It will quite difficult to understand all the minor details in brain MRI, as one has to study all the anatomy.
Report has explained the all structures in brain like...
My son had an MRI done yesterday on his right knee (baseball injury six weeks prior). Some findings were:
1. thin Bakers cyst extending superiorly deep to the semimembranosus uscle.
2. There is an abnormal marrow signal involving the proximal fibula. This is seen involving the epiphysis and proximal metaphysis [What is this?]
3. periosteal thickening with increased signal along the lateral proximal fibular metaphysis which is incompletely visulatized.
4. Periosteal thickening measures up to 4.5 mm in thickness and extends posteriorly as well.
5. x-rays from 3/28/13 reviewed show no osseous abnormality of the proximal fibula.
What does this mean?
MD hi dear
1.baker cyst is an incidental finding and symptom due to cyst depends on size of cyst.
2.abnormal marrow signal intensity is incomplete language it depends on how it look on various sequence of MRI.
3.periosteal thickening may be due to infection.
4.xrays as compared to MRI have much...
Yes, I just had a MRI done and there was a black shadow in the middle of it. This is my second MRI as my Dr. wanted to follow up on an incidental finding. The reason I got a MRI was because the right side of my face keeps getting numb. Should I worry?
MD Hi,
Thanks for your question.
Numbness in one side of face is neurological problem.
Your Doctor might have found some problem in MRI.
Hence he asked you to follow up.
Do follow doctor's advice and take medication as per doctor advice.
Thank you.
This is my MRI results and I wanted to know what the meaning of this is. Here it is.

Ten days following a traumatic incident, one radiologist reviewing an MRI sees a complete ACL tear from its femoral attachment. Five months later and another MRI, another radiologist sees an intact ACL with signal abnormality in the middle and distal and a tiny intrasubstance ganglian cyst in the middle of the ligament . What to do? ... another MRI with a different radiologist?
MD Hi,
Thanks for writing in.
I would have appreciated seeing both MRI scans before giving an opinion. I suggest you take the earlier MRI to the second radiologist and request an opinion and discussion of the same with your doctor.
Hope this helps
I got a MRI done over a year ago. The paper lets me know; "There is a left middle cranial fossa presumed arachnoid cyst measuring 40 mm with mass effect on the adjacent left temporal lobe." I got this MRI done because my headaches were getting really awful. They are only worse and ive had these headaches for about maybe 3 years. They just keep getting worse. When I went to a neurologist he told me I was "depressed" and needed to be on suicide watch. I am clearly not suicidal. I decided to take matters into my own hands. I cannot figure out why my headaches are getting this bad. I have a referral out for another MRI as well. Can you let me know what this kind of cyst can cause or do to me and if I need real help.
MD Does she suffer from a fever by any chance?
If so, I would suggest that she consider narcotic pain medication to relieve her 3 levels of pain. Her severity of pain sounds like she would only benefit from th pain medication, and it would improve her overall quality of daily life. If she suffers...
Recent questions on MRI
MD Is microvascular leukoencephalopathy progressive? My mother had an MRI done in 2007 showing white matter disease, subcortical atrophy and small vessel disease. Over the past 6-7 years she had been falling in the house and I noticed after the falling she had been experiencing some forgetfulness. She has been to a neurologist about 5 years ago and he had given her a mini-mental state test, and sent her for neuropsych testing. She also suffers from renal insufficiency due to hypertension (she is in Stage 3). She was in stage 4 but a nephrologist has her in stage 3 due to the right medications. Her mother had died from uremic poisoning over 50 years ago (no dialysis then). Anyway, the neurologist based on his examinations and testing feels that she is in a mild to moderate stage of alzheimer. Her cardiologist told me that she has microvascular leukoencepahlopaty (she also has hardenining of the arteries). Her primary care physician feels that her dementia is microvascular (AKA vascular due to small vessel disease; she also has diabetes, coronary artery disease, hypertension, hypothyroidism, cholesterol.) She was a smoker, but stopped about 17 years ago. She also has perepheral artery disease. She is on many medications including aricept and namenda. She also experiences parkinson-like tremors. She had a eeg showing a slows of speech language done about 4 years ago. Based on what I have told you is this dementia of a vascular origin, or is it a mixed dementia? She is currently 86 years old and resides in a nursing home. I know I witnessed while she was at home some forgetfulness like leaving a stove on, poor hygiene, moods swings (verbally and hitting). Also, she would have auditory & visual hallucinations (hearing music, talking to imaginary people). I thought at this point she would be better in a facility where she is exposed to people her age and mind stimulation would be more available than staying at home with a home health aide. She had a sister who had passed away last year at 83 years old from alzheimer. Could both sisters have the same thing? I know her sister had hypertension and atrial fib.
MD cervical issue I have a c4_c5 buldging disc and stenosis from c5 to c7. i have loss of balance, neck pain, poor walking, ear ringing, and now short term memory loss and poor recall. is the memory loss due to this. i am 53 year old male. my mri showed clear on my brain.
MD I am a 65 year old lady, 5 9 , 142 lbs and have been suffering for approx 6years with pressure, ringing in both ears. I have been treated for TMJ with dental appliances and trigger point injections. I have been diagnosed with sleep apnea and sleep with a CPAP machine I am now trying Prolotherapy in the TMJ joint ($150.00) per injection. I am also seeing an upper cirvical chiropractor for a shifted atlas. The muscles in my neck are very tight and I have a continuous headache. Xrays and MRI show a weakness in the muscles on the right side where I first started with the pain. When I first started with this I awoke with no hearing on the right side and my doctor said it was alergies and it would go away when the weather changed in the fall. Some of the hearing came back but I then had the ringing and headaches. I also now have a hearing aid to overcome the muffled sound and ringing in my right ear. I am tired all of the time and find it hard to concentrate. I do not have medical coverage. Any ideas would be most appreciated. Eileen My ears ache
