Magnetic Resonance Imaging (MRI) with 2.0 Tesla superconductive magnet developed by Korea Advanced Institute of Science was performed in 25 patients with various abdominal diseases and compared with X-ray computed tomography(CT). MRI was obtained with spin echo technique using a variety of pulse sequence and various slice orientation including axial, sagittal and coronal section in order to evaluate the diagnostic value, limitation and to determine the optimal pulse sequence in various abdominal diseases. MRI demonstrated the capability of detecting the lesions shown on CT in all cases and also detected one case of diffuse hepatocellular carcinoma which was not seen on CT. MRI showed capability of differentiation of various liver mass including hepatocellular carcinoma, hemangioma and simple cyst. MRI showed better anatomical resolution of tumor in retroperitoneum and pelvis, however CT delineated alimentary tract disease better than MRI did.
