radiography and x-ray computed tomography (x-ray ct) in that it generates images using x-rays. the original difference was that radiography fixed still images on film whereas fluoroscopy provided live moving pictures that were not stored. however, today radiography, ct, and fluoroscopy are all digital imaging...
resonanceimaging (mri). ultrasounds are only useful in the very young children that still have open soft spots. this study is very good at looking at the size of the ventricles but doesn't provide as much detail as a ct or mri does about the structure of the brain tissue itself. a ct is sort of the...

three different times after the dye is injected, to get the best picture of abnormal areas in the liver. this is called triple-phase ct. a spiral or helical ct scan makes a series of very detailed pictures of areas inside the body using an x-ray machine that scans the body in a spiral path. mri (magnetic...
