A review of imaging modalities in pulmonary hypertension

First Author: Ascha, ML, Last Author: Tonelli, AR

V/Q scan is the imaging modality of choice for screening patients with suspected CTEPH due to its high sensitivity.

A normal- or low-probability V/Q scan effectively excludes CTEPH with a sensitivity of 90%–100% and a specificity of 94%–100%, compared to CTPA which yields a sensitivity of 50%–98% with similar specificity.
