Abstract

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. The findings on contrast enhanced CT scan were compared with those on MR.
RESULTS
In five cases, the lesions were slightly hyperintense on T1 and FSE T2-weighted images, hypointense on fat-suppressed images, hyperintense on in-phase image, and presented a considerably diminished signal intensity on opposed-image. Focal hypointensity areas 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.
