Question

Which of the following is a technique used to minimize artifacts from patient motion in exams of the chest

1. suspended respiration
2. shortened scan time
3. patient immobilization devices

Answer 1

The techniques to minimize motion artifacts in chest exams include suspended respiration, shortened scan time, and patient immobilization devices. Isotopes with short half-lives are used to limit radiation exposure.

Step-by-step explanation:

The technique used to minimize artifacts from patient motion in exams of the chest includes suspended respiration, shortened scan time, and the use of patient immobilization devices. Suspended respiration involves instructing the patient to hold their breath during the scanning process to prevent motion from breathing. Shortened scan times are achieved by using faster scanning technologies, which reduce the time a patient must remain still. Patient immobilization devices may be employed to physically restrict movement during the scan.

Using isotopes with short half-lives in medical imaging limits the radiation dose to the patient because these isotopes decay more quickly, reducing the duration during which the patient is exposed to radiation.
