Abstract :
Twenty patients with cardiovascular diseases were examined using a 1.5-T magnetic resonance imaging (MRI) unit, and several parameters of both ventricles, such as ejection fraction (EF), end-diastolic and end-systolic volumes (EDV and ESV, respectively), were quantified by an experienced operator using two methods: 1) our semiautomatic segmentation method based on edge detection, iterative thresholding and region growing techniques, and 2) a commercially available software package based on manual contour tracing.
