Perfusion scintigraphy of a patient with chronic thromboembolic pulmonary hypertension showing multiple wedge-shaped perfusion defects. The ventilation study (not shown) was normal. a) Anterior, b) posterior, c) left posterior oblique and d) right posterior oblique.

a) Maximal intensity projection from a computed tomography pulmonary arteriogram showing amputation of the basal segment of the right lower lobe and web disease in the left lower lobe in keeping with proximal chronic thromboembolic pulmonary hypertension (CTEPH). Enlargement of the bronchial arteries is also visible. b) Wedge-shaped areas of reduced attenuation in the lung parenchyma indicative of mosaic perfusion consistent with CTEPH.

Pulmonary angiography in the right lung (a, c, e and g) and the left lung (b, d, f and h) of a patient with chronic thromboembolic pulmonary hypertension. The first image (a–d) was taken at a non-specialist centre with suboptimal vascular opacificaiton and the patient was considered inoperable. The second pulmonary angiography (e–h) was undertaken at a specialist surgical centre with selective angiography showing proximal disease, and resulted in the patient receiving successful pulmonary endarterectomy surgery. a, b, e, f) Anterior view and c, d, g, h) lateral views.

Magnetic resonance angiography from a patient with chronic thromboembolic pulmonary hypertension a) pre- and b) post-endarterectomy. Unlike other forms of imaging, magnetic resonance angiography does not utilise ionising radiation and is useful for follow-up examinations.
