Thoracic-abdominopelvic contrast-enhanced dual-source computed tomography with a high-pitch acquisition protocol and free breathing for reducing motion artifacts and scan time in patients with cancer: a prospective study.

ABSTRACT:

Background

Contrast-enhanced computed tomography (CECT) is critical for cancer management. Although high-pitch dual-source computed tomography (DSCT) effectively reduces radiation and enhances image quality, its clinical benefits in free-breathing thoracic-abdominopelvic scans remain unclear. This study investigated DSCT-based high-pitch CECT in terms of image quality and scan efficiency in non-breath-holding patients with cancer.

Methods

A total of 169 patients with cancer who underwent thoracic-abdominopelvic contrast-enhanced DSCT were enrolled: 84 non-breath-holding patients underwent a free-breathing high-pitch examination (Group 1: pitch 3.0), and 85 breath-holding capable patients matched for age, sex, and body mass index underwent the standard-pitch examination with
