Tc-99m macro aggregated albumin scintigraphy – indications other than pulmonary embolism: A pictorial essay
A 69-year-old male patient, who is a known case of right hepatocellular Ca with right portal vein thrombosis, was referred for Tc-99m MAA scintigraphy for planning liver radionuclide microspheres therapy. Tc-99m MAA scintigraphy showed significant MAA uptake corresponding to the site of CT detected liver tumor. There was minimal MAA shunting in bilateral lungs. No other extra hepatic sites of abnormal MAA uptake were seen. Patient was thus considered for liver radionuclide microsphere therapy with reduction in administered activity [Figures and ].
