A 62-year-old male with hepatocellular carcinoma and no prior radioembolization
was injected with 99mTc-MAA via right groin access into the left
hepatic artery and imaged 70 minutes after injection, with calculated lung shunt
fraction of 5%. He underwent 90Y-radioembolization 27 days
later without complication.
Axial, coronal, and MIP SPECT (Row A), axial and coronal fused SPECT/CT (Row B),
axial and coronal CT (Row C), and anterior planar (D) images demonstrate
radiotracer uptake in a recanalized paraumbilical vein in this patient with
underlying cirrhosis and portal hypertension. Anterior planar images also
demonstrate radiotracer uptake in the salivary glands and thyroid gland.
Radiotracer uptake in the stomach and kidneys (not shown) was also present.
