Re: mri worry!!
Sometimes it could be something as simple as the MRI scan was "protocolled" wrong and the wrong images might have been acquired and the wrong type of radiologist might have reported originally on the scan (MRI scans are done on the same area at different frequencies and the images are created with different algorithms depending upon the reason for the scan and pathologies they are looking for, for example some images water is white, fat is black, or fat is white, etc. there are things like T1, T2, FATsat, STIR, all sorts of different things). Also perhaps he just moved during acquisition and the images were not clear. The technologist might have thought that the images were okay at the time - but the radiologist reporting might just want more or a different type of radiologist may want different type of images. Hopefully it is for one of these reasons - nothing serious. There is that risk that it is to better see a pathology as well - but there is no point in worrying, the good thing is that he is getting more imaging soon to better show them what they are interested in. Hopefully you get answers soon.
