Can you Dota-tate that?
47 year old female with history of gastric bypass admitted with abdominal pain. Routine CT obtained in the ED with IV contrast, shows enhancing mass in the porta hepatis, between the duodenum and the IVC. The differential is wide....
Spectral analysis reveals a small enhancing nodule in the gastric antrum with intense iodine uptake. This is very easy to overlook on conventional images.
My friend the IR doc does a transhepatic biopsy, and path comes back as carcinoid. A Ga-68 Dotatate PET scan confirms a gastric carcinoid, with uptake in the gastric submucosal nodule and the porta hepatis metastasis.
The lower keV images, with their ability to significantly enhance iodine, help quite a bit with visualizing enhancing tumors.
