76 yo female with left renal mass (not present on CT from 13 years ago). MRI demonstrates a nice example of segmental enhancement inversion (SEI). ccLS = 3, no microscopic fat.

In SEI, parts of the mass that enhanced early become hypoenhancing on delayed images, and parts that were hypoenhacing early become hyperenhancing later (arrows).

Surg path = oncocytoma

If you're having trouble choosing between an extracellular or hepatobiliary contrast agent for liver MRI, why not both? Read about the indications, protocol, and utility of dual-contrast liver MRI, now available in @RadioGraphics at https://t.co/hCVLQHQf4v

We have studied the natural history of renal masses… but do you know how fast venous tumor thrombi grow?

@ItaniMalak @SARBiliaryDFP Type 1 choledochal cyst?

Review the case examples in this article to evaluate major and ancillary MRI features of the clear cell likelihood score (ccLS) algorithm for assigning a likelihood score to a small solid renal mass. https://t.co/XvhpwQLxV3 @nupedogg @DavidBallardMD @ItaniMalak @BCUSWORTH

First time lecturing in Scarpellino in over a year. Our first year class served as the portal for chest Jeopardy. The enthusiasm was inspiring. Second year Dan Friedman was right…. Laughter and collegiality make any learning experience better @MIRimaging
