Synopsis

Keywords: Liver, Body

Motivation: The image quality of free-breathing sequence (4D FreeBreathing) is not stable.

Goal(s): To identify the relative factors for degraded image quality in 4D FreeBreathing.

Approach: Images using 4D FreeBreathing sequence were retrospectively obtained from 73 patients and logistic regression analysis was conducted.

Results: The presence of cirrhosis and unacceptable image quality on pre-contrast images were the relative factors for degraded image quality in 4D FreeBreathing.

Impact: It is not preferable to perform 4D FreeBreathing in patients with cirrhosis and unacceptable image quality in pre-contrast scanning. Using the information of cirrhosis and image quality at pre-contrast, we may be able to select the appropriate candidates.
