Axial images from pre 90Y 3D CT angiogram. a Intraprocedural selective arterial-phase contrast-enhanced CT of the right hepatic artery obtained during workup arteriography demonstrates hyperenhancing tumors with b hypoenhancing lesions along the posterior inferior liver, thought to be metastases supplied by branches of the right inferior phrenic artery. c SPECT/CT images after administration of [99mTc]Tc-MAA into the right hepatic artery demonstrates intense activity within the majority of tumors in the inferior right hepatic lobe with photopenic peripheral areas that correlate to the hypoenhancing areas seen on 3D CT angiogram. d SPECT/CT images also demonstrate an area of intense focal activity along the posterior surface of hepatic segment VII (arrow), representing subserosal liver metastasis which may correspond to the plaque-like lesions seen during aborted initial surgery
