Randomized Controlled TrialOptimizing MRI scan time in the computation of pharmacokinetic parameters (K(trans) ) in breast cancer diagnosis.
To assess the effects of reduced scan time in dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) of breast for the evaluation of pharmacokinetic parameters (K(trans) , ve , and kep ). ⋯ Reducing the acquisition time for the K(trans) and ve measurement up to 60 seconds yields reasonable accuracy for both and can be incorporated in the routine DCE-MRI protocol for evaluation of enhancing breast lesions.

Randomized Controlled TrialTiming of the hepatic arterial phase at Gd-EOB-DTPA-enhanced hepatic dynamic MRI: comparison of the test-injection and the fixed-time delay method.
To compare the fixed-time- and the test-injection method with respect to the image quality of hypervascular hepatocellular carcinoma (HCC) and the adequacy of timing of the hepatic arterial phase (HAP) in Gd-EOB-DTPA (EOB) enhanced MRI. ⋯ At EOB-enhanced hepatic dynamic MRI, the test-injection method yielded better image quality of hypervascular HCC and improved adequacy of timing of HAP.
