Reducing respiratory artifacts in gadoxetic acid-enhanced magnetic resonance imaging via a patient-adapted breath-holding training strategy.

ABSTRACT:

Background

In gadoxetic acid-enhanced liver magnetic resonance imaging (MRI), an inadequate breath-holding strategy is an independent risk factor for image quality degradation in single-phase arterial acquisition. Therefore, optimizing breath-holding training protocols is critical. This study aimed to assess the effectiveness of a nongradual breath training protocol combined with contrast dilution for reducing arterial phase (AP) respiratory artifacts in upper abdomen gadoxetic acid-enhanced MRI.

Methods

In this retrospective study, we enrolled 126 patients (91 males; mean age 52.65±11.07 years) who underwent gadoxetic acid-enhanced upper abdomen MRI for the first and only time from May 2019 to February 2020. All patients were divided into four groups according to different
