Acceptable Dosage of Radiation in short time frame

I appreciate that you are concerned about your radiation exposure and it is always worth asking your physician whether exposure to radiation is necessary or whether there is another test that may give the diagnosis as accurately with less risk. Having said that, often imaging using radiation helps detect serious diseases and therefore without having the infor...
high t1 signal on a c spine
Jul 09, 2008 04:19PM in the Diagnostic Radiology Expert Forum
I am sure your study will be read by a radioogist who will be able to give you more answers. There are a few things that can cause high signal on T1 mainly fat, blood and contrast. I wonder whether there was high t2 signal with contrast enhancement on T1 in the same region. However, the best thing is to get a radiology opinion and they can correlate the imagi...
long term risk with repeated CT scans

The absolute risk of radiation exposure is unknown in the medical field.

On the other hand, the benefits of fully investigating patients to investigate for potentially dangerous condition...

As your symptoms are persisting then I would recommend you seek further clinical assessment to determine whether further investigations may be useful.
CT scan reading question

THe caecum is a region of the intestine at the start of the large bowel. Neither ultrasound nor a standard CT scan of the abdomen/pelvis are optimal at imaging the colon. There can be many causes of thickening such as bowel muscle contraction, inflammation including infection or cancer. The colonoscopy will allow direct visulisation of the bowel wall and if n...
