In patients with breath-holding difficulties,
breathing artifacts can result in dramatically reduced image quality during
hepatobiliary phase imaging. Rapid Cartesian as well as radial acquisition
techniques are approaches to minimize these artifacts. In 21 patients, both
techniques were used and compared regarding image quality and lesion conspicuity.
For most patients, a high flip angle Cartesian sequence with short breath-hold
interval was feasible and resulted in superior overall image quality. Radial
techniques proved to be a valuable option for the few patients who were unable
to hold even short breath-hold intervals.
