OK, this is not for beginners!
Who gets all answers is the king (or queen) of Radiology!
1. What type of study is this?
2. What was done?
3. What is the very bright (yellow/red) area?
4. What are the arrows pointing to?
OK, here comes the solution:
This is a 79-year-old male with history of gallbladder malignancy, metastatic to liver was referred for shunt calculation prior Y-90 Therasphere treatment. 4.4 mCi of Tc-99m macroaggregated albumin (MAA) was administered in the left hepatic artery. Subsequent SPECT/CT images (see image) demonstrate accumulation of MAA in the left liver lobe. In addition a linear uptake in the anterior abdomen extending from the edge of the liver inferiorly toward umbilicus is noticed, corresponding to the paraumbilical vein (arrows), best appreciated on the projection image (right lower image). No other vessels demonstrate radiotracer activity.
