Frequency of Inferior Vena Caval Abnormalcy due to a Juxtaposed Pathology

Summary Radionuclide inferior vena cavagrams were done in 135 patients who had hepatomegaly, splenomegaly or a mass in the vicinity of the inferior vena cava (I. V. C.). 2-5mCi 99mTc phytate, 99mTc S colloid, 99mTc O4 -, 99mTc-LIDA, 99mTc pyridoxyledene glutamate or 113min colloid were injected directly and rapidly into either a malleolar or a femoral vein while the patient lay supine under the 13.5 detector head of a scinticamera. Rapid sequential scintiphotos were manually taken at approximately 1 sec. interval for 20-30 sec. Thus iliac vein, I. V. C., cardiopulmonary zone in infants, aorta and the arterial ph…
