My mris generate vastly different interpretations. some see tumors, lesions, hyperintensities. others see nothing. lesions are diagnosed as everything imaginable. no objective standard? what's up?

Medicine: Is definitely not an exact science and the interpretation of radiologic studies can be quite variable. Discuss with your doctor so that the possibilities can be narrowed down depending on your history exam and other tests.

MRI of what?: Mris are very standardized with extensive detailed texts describing what we call 'differential diagnoses' for MRI findings. These are essentially lists of possibilities that an MRI abnormality may represent. Depending on the body part, often times two or three things look alike and we provide this list - often to be solved by biopsy. Hope this helps.

MRI: Not sure which MRI you are talking about. Is it of the brain, abdomen, chest? You should understand that MRI or ct scans are just "shadow" of your body organs. When we interpret we do come across atypical findings that baffle us. All radiological interpretations should be correlated with clinical findings to arrive at a reasonable diagnosis.
