According to a study in the September Journal of Nuclear Medicine , young women at risk of a pulmonary embolism should first undergo a ventilation/perfusion lung scan rather than a CT angiogram. “A ...

How Does a VQ Scan Work? The VQ scan is a nuclear scan. It measures airflow, called ventilation, and blood flow, called perfusion, in your lungs. The V and Q make up a math equation that helps doctors ...

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.

Educating physicians about ventilation-perfusion scanning as an alternative to CT for the diagnosis of pulmonary embolisms led to a 23 percent decrease in patient exposure, according to a study ...

Abnormal lung scans obtained from patients with pulmonary embolism, pulmonary tuberculosis, chronic obstructive pulmonary disease and carcinoma of the lung were analyzed in an attempt to classify the ...

Rapid and accurate diagnosis of pulmonary embolism will improve survival and quality of life because treatment decreases mortality and the likelihood that thromboembolic pulmonary hypertension or the ...

When you breathe, a certain fraction of your air enters the lungs and blood flows through the capillaries. When this ratio is above or below 0.8, you may have ventilation/perfusion (V/Q) mismatch. A V ...
