متن کاملبررسی ارتباط مقاومت شرایین ریوی (PVR) و اندکسهای عملکرد بطنی
Abstract Background: Pulmonary vascular resistance (PVR) index is an important hemodynamic variable in determining the severity of cardiopulmonary diseases. This study was done to define the relationship of echocardiographic parameters of ventricular function with PVR. Methods: Mean PVR of 40 patients with cardiac disease was compared with the left ventricle diastolic function indices (LVEF...
متن کاملPulmonary studies using positron emission tomography.
The detailed investigation of regional differences in lung function at a local level began when suitable gamma-ray emitting isotopes and focused external radiation detectors (especially the Anger gamma-camera) became available. A major recent advance has been the development of positron emission tomography (PET), which provides a powerful combination of highly accurate tomographic reconstructio...
