By
Jonathan S. Batchelor
"One size fits all" may be words to live by when purchasing a knit ski cap, but the adage does not hold true in PET/CT scanning. It is the application that should determine the CT configuration in combined systems, according to PET expert Dr. Homer Macapinlac.

Farewell to fusion: Contrast MRI edges CT in postbrachytherapy exams
By
Eric Barnes
CT/MRI fusion is a waste of time for postbrachytherapy imaging of the prostate, say researchers from Boston and Vienna. Not only does contrast-enhanced MRI detect seeds nearly as well as CT, they say, but MRI’s superior soft-tissue contrast properties often make it the only way to tell whether seeds have migrated outside the organ.
