Role of Multi-Detector Computed Tomography in Assessment of Pulmonary Arterial Hypertension

Abstract

Pulmonary arterial hypertension (PAH) may be suspected based on the clinical history, physical examination and electrocardiogram findings but imaging is usually central to confirming the diagnosis, establishing a cause and guiding therapy. The diagnostic pathway of PAH involves a variety of complimentary investigations of which computed tomography pulmonary angiography (CTPA) has established a central role both in helping identify an underlying cause for PAH and assessing resulting functional compromise. In particular, CTPA is considered as the gold standard technique for the diagnosis of thromboembolic disease. This article reviews the CTPA evaluation in PAH, describing CTPA techniques, a systematic approach to interpretation and spectrum of key imaging findings.

Evaluating Signs of Pulmonary Hypertension on Computed Tomography and Correlating With Echocardiography: A Study at a Tertiary Care Hospital

“…Essam et al also correlated the RPA and LPA with mPAP; there was no correlation between LPA and mPAP. On the contrary to our results, RPA showed a strong correlation with mPAP [16].…”

“…Following MPA bifurcation, the broadest section measurements of the right and left pulmonary arteries were taken [16].…”

Cutaneous, Lacrimal and Testicular Lymphomas; Case Series

“…Multidetector PET-CT was provided to be better and more accurate in the detection of extra-nodallesions. It allows for accurate FDG localization without compromising the time of acquisition (5) . Some reports pointed out that diffuse large B cell lymphoma was more prone to express extra-nodal infiltration compared to other types of lymphomas.…”
