Value of T1 and T2 relaxation times from echoplanar MR imaging in the characterization of focal hepatic lesions.


OBJECTIVE The purpose of this study was to determine the value of echoplanar imaging in characterizing focal hepatic lesions on the basis of image-derived T1 and T2 relaxation times. SUBJECTS AND METHODS Forty-six proven hepatic lesions were analyzed: 24 solid (21 metastases, three primary liver tumors) and 22 nonsolid (11 hemangiomas and 11 cysts). Mean… (More)
