Purpose: We investigated whether a low-field MR unit (0.2 T) could demonstrate and determine the size of the lymph nodes in the hepato-duodenal ligament that were previously found on ultrasound.
Material and methods: Eighteen patients were examined with ultrasound, MR and liver biopsy on consecutive days.
Results: Two-thirds of the enlarged nodes detected by ultrasound were also detected with the low-field MR technique. However, the size of the nodes was slightly larger on ultrasound.
Conclusion: Compared to low-field MR, ultrasound appears to be superior in the evaluation of lymph nodes in the liver hilus.
