<prompt> Evaluation of cardiac valve motion and fetal hea rate is done in which mode of Ultrasound?A-modeB-modeM-modeD-mode  <response>: M-Mode Ultrasound is Motion mode and is used to evaluate Fetal Hea Rate and Cardiac Valve movement and echocardiography. Also used for detection of pneumothorax. A Mode Ultrasound is Amplitude Mode for measuring Axial length of Eyeball and orbital biometry A scan in Opthalmology is the A Mode Ultrasound B Mode Ultrasound is most commonly used mode. It is Brightness mode for routine Ultrasound. M Mode used in antenatal scan to calculate feral hea rate.
