Quantitative Dual Energy Computed Tomography in Pulmonary Hypertension

NCT03901287 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 60

No results posted yet for this study

Summary

Pathophysiological mechanisms leading to pulmonary hypertension (PH) are complex. Quantitative computed tomography (QCT) can help us to study morphological alterations in patients with PH. These CT morphometrics are useful to predict the degree of PH severity at least in PH secondary to chronic obstructive pulmonary disease (COPD). We hypothesized that assessing lung perfusion using dual energy CT (DECT) can refine our knowledge on PH pathophysiology and help to predict PH severity irrespective of its etiology

Conditions

  • Pulmonary Hypertension

Interventions

OTHER

dual energy CT scans

The procedure involves post processing and analysis of reconstructed images from dual energy CT scans available at the Bordeaux University Hospital and used in routine care, which will allow us to collect morphometric data (bronchial wall thickness and cross sectional area of small pulmonary vessels) and to assess pulmonary perfusion by studying iodine mapping and quantifying pulmonary perfusion blood volume (PVB)
