Subtraction MR Venography Acquired from Time-Resolved Contrast-Enhanced MR Angiography: Comparison with Phase-Contrast MR Venography and Single-Phase Contrast-Enhanced MR Venography

OBJECTIVE To evaluate the image characteristics of subtraction magnetic resonance venography (SMRV) from time-resolved contrast-enhanced MR angiography (TRMRA) compared with phase-contrast MR venography (PCMRV) and single-phase contrast-enhanced MR venography (CEMRV). MATERIALS AND METHODS Twenty-one patients who underwent brain MR venography (MRV) using standard protocols (PCMRV, CEMRV, and ...

Radionuclide plethysmography and Tc-99m red blood cell venography in venous thrombosis: comparison with contrast venography.

Radionuclide plethysmography (RPG) is a new technique that uses Tc-99m labelled red blood cells to ascertain changes in venous volumes by detecting the change in counts in response to the inflation and deflation of proximal thigh cuffs. Diagnosis of ileofemoral venous occlusion is possible using this technique, which also provides kinetic data of venous outflow. A range of normal values was def...

Dynamic Radionuclide Venogram Correlation with Radiographic Contrast Venography

A simple technique of dynamic radionuclide venographyusing a Searle LFOV gamma camera and an associated whole-body scanning couch-was investigated to demonstrate venous flow from the foot to the inferior vena cava on a single image. Results of this method were correlated with radiographic contrast venography in prospective studies in 84 patients. Correlation between radionuclide and contrast ve...

Intravenous leiomyomatosis diagnosed by catheter-based contrast venography

Introduction: Intravenous leiomyomatosis (IVL) is a rare histologically benign smooth muscle tumor that often originates form uterus and common iliac vein, sometimes extends to the right heart. case report: A rare case diagnosed in catheter-based contrast venography with a pathological finding is described, together with a comparative analysis of all the previous published cases. conclusion: In...
