Question

During a coronary calcium scoring study which technique will minimize the radiation dose to the patient?

1) prospective cardiac synchronization
2) retrospective cardiac synchronization
3) no cardiac synchronization
4) pitch <1

Answer 1

Prospective cardiac synchronization is the technique that will minimize the radiation dose to the patient during a coronary calcium scoring study.

Step-by-step explanation:

The technique that will minimize the radiation dose to the patient during a coronary calcium scoring study is prospective cardiac synchronization.

Prospective cardiac synchronization is a technique that involves gating the CT scanner to acquire images only during a specific phase of the cardiac cycle when motion is minimal. This technique reduces radiation exposure to the patient because images are acquired during a shorter period of time.

In contrast, retrospective cardiac synchronization involves acquiring images throughout the entire cardiac cycle and then reconstructing images from specific phases of the cycle. This technique results in a higher radiation dose to the patient.
