Diagnostic Workup for Pulmonary Embolism

The V./Q. scan is considered more accurate than pulmonary angiography.

Arterial blood gas analysis is not required for diagnosing PE.

Chest x-ray findings are more reliable for diagnosing PE than MDCTA.

A specially trained team is not necessary for performing a V./Q. scan.

ECG abnormalities are not associated with PE.

In a V./Q. scan, a catheter is threaded through the artery to inject dye into the lung.

MDCTA is less invasive than a V./Q. scan.

V./Q. scan evaluates the same regions of the lung for percentage of V./Q. in each area.

The sensitivity of a V./Q. scan is lower than that of an MDCTA.

IV administration of a contrast agent is not required for a V./Q. scan.
