[A clinical trial of whole liver simultaneous dynamic MR imaging and its usefulness].
A clinical trial of whole liver simultaneous dynamic MRI was done. In 23 second whole liver was able to be scanned using parameters of filed echo method as follows: TR = 315 msec, TE = 7 msec, Flip angle = 70 degrees or 90 degrees, MAT = 50%, ECD = 60%, FOV 40 cm and no presaturation. Even 2-3 mm nodules of metastatic tumors and small daughter nodules of hepatocellular carcinoma such as 5 mm were demonstrated in the arterial phase clearly.
