Pulmonary veno-occlusive disease: antemortem diagnosis from roentgenographic and hemodynamic findings
Abstract:
A 17-year-old boy with pulmonary veno-occlusive disease underwent Swan--Ganz catheterization. A normal pulmonary capillary wedge pressure was recorded in the presence of severe pulmonary arterial hypertension and roentgenographic evidence of pulmonary venous congestion. This triad of findings permitted an unequivocal diagnosis of pulmonary veno-occlusive disease, which was later confirmed at autopsy. The hemodynamics of this condition and of others included in the differential diagnosis are presented schematically.

Radiological Investigation II: MRI and Ventilation Perfusion Scan
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
Radiological Investigation III: Pulmonary Angiogram and PET Scan
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
