Lung microvasculopathy in chronic thromboembolic pulmonary hypertension: high-resolution findings with photon-counting detector CT in 29 patients.

ABSTRACT:

Purpose

To evaluate CT findings suggestive of lung microvasculopathy in patients with chronic thromboembolic pulmonary hypertension (CTEPH).

Materials and methods

Twenty-nine patients were scanned with high-spatial resolution on a photon-counting detector (PCD)-CT unit. A maximum of three pairs per patient, each composed of hyper- and hypo-attenuating areas of mosaic perfusion, were selected.

Results

Comparative analysis of the 86 selected pairs showed: (a) a higher frequency of ill-defined micronodules (p = 0.008), lobular ground-glass opacities (p = 0.01) and haziness (p = 0.003) in hypoattenuated areas; (b) there was no significant difference in the frequency of neovascularity (p = 0.43). Similar trends were observed in hypoattenuating areas of the 66 pairs studied
