Multidetector computed tomography for detection and characterization of pulmonary hypertension in consideration of WHO classification.
Abstract
OBJECTIVE
We evaluated the reliability of various multidetector computed tomography (MDCT) parameters for diagnosis and severity assessment
of pulmonary hypertension (PH) with consideration of World Health Organization (WHO) classification.
METHODS
A total of 172 patients were included in this retrospective study. One hundred fourteen patients had a diagnosis of PH (mean
pulmonary artery pressure ≥25 mm Hg), and 58 patients without PH (mean pulmonary artery pressure <20 mm Hg) served as control
subjects. The patients with PH were grouped according to the WHO classification based on PH etiology.
RESULTS
The patients with PH had significantly greater main, left, and right pulmonary artery diameters than the control subjects
(P < 0.001). No significant differences within the PH subgroups were found. Receiver operating characteristic analysis showed
reasonable sensitivity and specificity for selected MDCT parameters. The severity of PH did not correlate with MDCT parameters.
CONCLUSIONS
Easy-to-determine MDCT parameters allow detection of PH independent of the WHO group. In patients with dilated aorta, the
vertebra can be an alternative internal standard. Severity of PH cannot be estimated by MDCT parameters.
