Technologist Track Session 02: CMR How To (2018)-Ventricular volumes

Video Transcription

Video Summary

The talk explains how cardiac MRI quantifies left and right ventricular volumes, ejection fraction, and mass for clinical decisions and prognosis. It covers step-by-step contouring of end-diastolic and end-systolic short-axis images, emphasizing correct basal slice selection, the 50% rule, and including the LV outflow tract. Papillary muscles and trabeculae are generally included for better reproducibility. For the right ventricle, short-axis or transverse imaging can be used, with transverse views preferred in abnormal anatomy. Key advice: be consistent, use long-axis views as a guide, and avoid basal slice errors.
