[Regional pulmonary ventilation and blood flow in patients with mitral valve stenosis according to radionuclide
Abstract:
It is shown, on the basis of ventilation and perfusion scintigraphy, that marked pulmonary flow redistribution from basal to apical departments, combined with relatively normal distribution of ventilation volumes, is a regular feature of mitral stenosis combined with pulmonary hypertension. The quantitative assessment of the intensity of pulmonary perfusion redistribution can be used as a measure of pulmonary hypertension. Also, a right-to-left unbalance was established in the pulmonary flow distribution, manifested as hyperperfusion of the left lung.

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...
