Left Ventricular Volumes and Ejection Fraction by Echocardiography [PDF]

open access: yesCirculation, 1971
Left ventricular end-diastolic and end-systolic volume, stroke volume, and ejection fraction were determined by biplane angiocardiography and echocardiography in 27 patients suspected of having heart disease. Angiographic volumes were calculated by the area-length method and echocardiographic volumes, from the left ventricular dimension of

Evaluation of the volume and volume fraction of the lateral ventricles in the Parkinsonism

open access: yesJournal of Experimental and Clinical Medicine, 2014
Parkinson’s disease (PD) commonly begins in late middle age and the course is slowly progressive. Ventricular enlargement, a nonspecific measure of brain atrophy, has been associated with PD. The aim of this study is to perform the measurements of the cerebral hemispheres and lateral ventricles using magnetic resonance imaging (MRI) in combination with
