Which of the following factors helps reduce peristaltic motion during an MRI of the abdomen?

Question

Quizplus · Accepted Answer

Physiologic gating is a technique that synchronizes the MRI data acquisition with the patient's respiration, thus reducing motion artifacts. Peristaltic motion is caused by the movement of the digestive tract, which is also affected by the patient's respiration. By synchronizing the data acquisition with the respiratory cycle, physiologic gating helps reduce peristaltic motion during an MRI of the abdomen. The other choices (B, C, and D) are not directly related to reducing peristaltic motion.
