Venography

MIP image from contrast-enhanced MR venography, with a color overlay, demonstrates the superior dural sinuses. ❋ Unknown (2010)

Reference standard diagnosis or exclusion was made by using various tests, including computed tomographic angiography and venography, ventilation-perfusion lung scan, venous ultrasonography, d-dimer assay, and clinical assessment. ❋ Stein (2010)

Background: The accuracy of gadolinium-enhanced magnetic resonance pulmonary angiography and magnetic resonance venography for diagnosing pulmonary embolism has not been determined conclusively. ❋ Stein (2010)

A research team led by Professor Wen He from Beijing Friendship Hospital, Capital Medical University, China, used multidetector computed tomography portal venography (MDCTPV) to study the collateral circulation of GV. ❋ Editors (2010)

Objective: To investigate performance characteristics of magnetic resonance angiography, with or without magnetic resonance venography, for diagnosing pulmonary embolism. ❋ Stein (2010)

A possible drawback seen with studies like ADVANCE-2, the investigators noted, is the sizeable proportion of patients who had suboptimal or no venography after treatment (36% of apixaban and 35% of enoxaparin patients) and therefore couldn't be included in the efficacy analysis. ❋ Unknown (2010)

Technically adequate magnetic resonance angiography and venography had a sensitivity of 92% and a specificity of 96%, but 52% of patients (194 of 370) had technically inadequate results. ❋ Stein (2010)

This team is using the ultrasound techniques originally used by Dr. Zamboni, as well as magnetic resonance studies of the veins (MR venography), MRI scans of the brain, and clinical measures to determine MS activity and atrophy. ❋ Unknown (2010)

Magnetic resonance pulmonary angiography and magnetic resonance venography combined have a higher sensitivity than magnetic resonance pulmonary angiography alone in patients with technically adequate images, but it is more difficult to obtain technically adequate images with the 2 procedures. ❋ Stein (2010)

The drugs were continued to 10 to 14 days, at which time venography was planned. ❋ Unknown (2010)
