N2 - During liver computed tomography (CT), scanning is performed with the raised arm position and an inhalation technique. However, for liver magnetic resonance imaging (MRI), the arms are placed at the sides of the body and an exhalation technique is used. This study was aimed at evaluating the effect that the patient’s arm position and respiration technique had on the ability to detect mammary glands in the scan range to discover unexpected mammary lesions during the liver MRI examination. Liver MRI and CT images were compared for 337 female patients. More than half of the mammary glands were included in 97.3% of MRI, but in 4.7% of CT. No mammary lesions were found during CT, whereas seven were found during MRI. The mammary lesions are more likely to be detected when the patient places her arms at the sides of the body and uses the exhalation technique during liver MRI.
