A novel diagnostic approach for assessing pulmonary blood flow distribution using conventional X-ray angiography.

ABSTRACT:

Objective

Quantitative assessment of pulmonary blood flow distribution is important when determining the clinical indications for treating pulmonary arterial branch stenosis. Lung perfusion scintigraphy is currently the gold standard for quantitative blood flow measurement. However, it is expensive, cannot provide a real-time assessment, requires additional sedation, and exposes the patient to ionizing radiation. The aim of this study was to investigate the feasibility of a novel technology for measuring pulmonary blood flow distribution in each lung by conventional X-ray pulmonary angiography and to compare its performance to that of lung perfusion scintigraphy.

Methods

Contrast-enhanced X-ray pulmonary angiography images were acquired at a frame rate of 30 frames per secon
