Clinical Significance of Retrograde Inferior Vena Cava and Hepatic Vein Opacification during Contrast Enhanced Tri-Phasic CT Abdomen Acquired as Part of F-18 FDG PET CT Scan - Learning Point For Nuclear Medicine Physicians: A Case Report and Literature Survey

Hepatic veins and inferior vena cava are opacified during the delayed venous phase on triphasic contrast-enhanced computed tomography (CECT) abdomen scan. However, their early opacification/visualization in the arterial phase is usually due to retrograde flow of intravenous contrast from the right a...

Sumario:Hepatic veins and inferior vena cava are opacified during the delayed venous phase on triphasic contrast-enhanced computed tomography (CECT) abdomen scan. However, their early opacification/visualization in the arterial phase is usually due to retrograde flow of intravenous contrast from the right atrium in patients with right-sided heart failure or right ventricular dysfunction. Awareness and recognition of this phenomenon is important for nuclear medicine physicians reporting F18 fluorodeoxyglucose positron emission tomography–computed tomography (FDG PET CT) scan with diagnostic CECT.
