Final answer:
In medical imaging, transverse and sagittal images should be obtained with and without color Doppler. Color Doppler is a technique used in ultrasound to detect motion and determine velocity. It is commonly used to monitor the fetal heartbeat, measure blood velocity, and detect occlusions in blood vessels.
Step-by-step explanation:
In medical imaging, after the location is determined, transverse and sagittal images should be obtained with and without color Doppler. Color Doppler is a technique used in ultrasound to detect motion and determine velocity through the Doppler shift of an echo. It uses color to indicate velocity, with the highest velocities shown in red and the lowest in blue. This technique is commonly used to monitor the fetal heartbeat, measure blood velocity, and detect occlusions in blood vessels.
