MDCT pulmonary angiography is replacing the ventilation-perfusion lung scan to diagnose suspected pulmonary embolism in hospitalized patients, say researchers from Rhode Island Hospital in Providence.

This article, the last in a five-part series on nuclear medicine imaging techniques, explains how ventilation/perfusion scintigraphy works and what precautions are required when it is used Nuclear ...

Pulmonary embolism is one of the leading causes of maternal death in the Western world. Because of the low specificity and sensitivity of the d-dimer test, all pregnant women with suspected pulmona ...

The advanced scans revealed reduced blood flow and mismatches in ventilation-perfusion, correlating with severe symptoms such as chronic fatigue and increased heart rate.

The prevalence of pulmonary embolism among patients hospitalized for syncope is not well documented, and current guidelines pay little attention to a diagnostic workup for pulmonary embolism in the ...
