Purpose : To characterize the MR findings of nontumorous focal low attenuated areas around the falciformligament on contrast enhanced CT scan. Materials and Methods : MR was used to study twelve patients who oncontrast-enhanced CT scan showed focal low attenuated areas around the falciform ligament. Imaging was carried outwith T1, FSE-T2, fat-suppressed T1, and fat-suppressed FSE T2-weighted pulse sequences at 1.5 T. Dynamic fastlow-angle shot(FLASH) imaging was performed in seven patients and chemical shift images were obtained in five. Thefindings on contrast enhanced CT scan were compared with those on MR. Results : In five cases, the lesions wereslightly hyperintense on T1 and FSE T2-weighted images, hypointense on fat-suppressed images, hyperintense onin-phase image, and presented a considerably diminished signal intensity on opposed-image. Focal hypointensityareas were visualized at 50-75 sec after contrast enhancement in three cases in which a lesion was not depicted oneither T1-or FSE T2-weighted images. Conclusion : Nontumorous focal low attenuated areas around the falciformligament were shown on MR imaging as focal fatty infiltrations or pseudolesions.
