15 liver hemangiom as Irom 10 patients were stud ied by mangetic resonance imaging (MRI) w ith 2.0 Tesla superconductive magnet in order to eva luate the detectability 01 the mass by MRI and to ana lyze the optimal pulse sequence in hi gh lield magnet. Identical multislice/multiecho techniques were used in all pati ents obtained with T1-and T2 weighted spin echo using TR 500, 1500, 2000 msec and TE 30, 60, 90, 120 msec. MRI could detect liver hemangiomas in all cases. Hemangioma tended to have sharp margin, homogeneous signa l intensi 야 and no capsu le and showed iso signal intensity in majority on SE 500/30 images. Hemangioma also had hi gh signa l inte n si 야 w ith prolongation 01 TR and TE. On T2 -weighted images obtain ed with 2000 msec TR and 60, 90, 120 msec TE, hemangiomas had signilicantly greater contrast between the mass and su rrounding li ver than that on T1 weighted im ages We believe that MRI may replace the angiography lor the diagnosis of hemangioma and may become th e procedure 01 choice lor lurther work up 01 suspected small hemangioma on so nography
