WebIn liver lesions, similar diagnostic data are obtained in dynamic and late phase MRI with either standard dose Gd-BOPTA or with a dose of 0.1 mmol/kg. Because there was a difference in only metastases in both groups, in oncological patients who are being investigated for liver metastasis, it is expe … WebMean motion scores for each MRI phase (un-enhanced, arterial, venous, late dynamic, and hepatobiliary phases) were compared by using the Friedman test with posthoc analysis. The frequency of severe respiratory motion artifact (defined as a mean motion score ≥ 4) according to MRI phase was compared by the Cochran Q test with posthoc analysis.
