Hello Dr. Tagal - is it you? Thank you, I just have a quick question. I am a patient if Dr. Yang, neuroradiologist in San Diego, ca. He performed surgery to embolize my cranial (dural) fistula (AVF). He is an out of area doctor, for my HMO.....and I have been having some difficulty getting back to him. My primary care doc ordered another post surgery MRI done. Until Dr. Yang, or other qualified MD can review the MRI (on CD)....I am trying to understand if I m better, worse, or about the same. The surgery was about 1.5 yrs ago. The radiologist that reviewed the CD, wrote in his report: 1. Flair images....the hypoT2 signal has decreased measuring 5 mm compared to 9 mm on previous scan. 2. Diffuse volume loss, more than expected for patients age without change. (I m almost 60 yrs). Can you explain please? (Thank you).
