Comparison of "one-stop" coronary and head-and-neck computed tomography angiography with different scan sequences using a wide-detector system: heart-to-cranial <i>vs.</i> cranial-to-heart.

ABSTRACT:

Background

"One-stop" coronary computed tomography angiography (CCTA) and head-and-neck computed tomography angiography (HNCTA) use heart-to-cranial or cranial-to-heart protocols with a wide-detector system. It is not yet known whether the HNCTA and CCTA scanning sequence affect the image quality. This study aimed to evaluate the image quality of one-stop computed tomography angiography (CTA) using two different protocols.

Methods

A total of 150 patients were included in this case-control study, and divided into three groups (A, B, and C; n=50 each). Patients in groups A and B underwent one-stop CTA scans, with CCTA completed first in group A and HNCTA completed first in group B, while patients in group C underwent separate HNCTA and CCTA scans. The subjective image quality
