Abstract

Purpose: The value of T-2 weighted turbo-spin-echo sequences with selective fat suppression (TSE-SPIR) in the detection and differential diagnosis of focal liver lesions was compared to TSE sequences and conventional T-1 weighted spin-echo (T-1 SE) sequences at 0.5 T. Methods: In 50 patients with focal liver lesions T-1 SE-, TSE-, and TSE-SPIR sequences were performed. Two independent readers evaluated the sequenceswith regard to the image quality, fat suppression, and the number andconspicuity of liver lesions. Quantitative analysis was performed by tumour-liver contrast-to-noise (CNR) measurements. Results: From a total of 118 liver lesions the T-1 SE sequence, the TSE sequence, and theTSE-SPIR sequence showed 85.6%, 83.9%, and 91.5%, respectively (p < 0.05). The tumour-liver CNR of malignant liver lesions was 30.2-46.6% higher on the TSE-SPIR sequence compared to the TSE sequence (p < 0.01). With the exception of fat-containing lesions there was no significant difference of CNR in benign lesions on both TSE sequences. Conclusion: With regard to lesion detection the TSE-SPIR sequence is superior to the TSE sequence without fat suppression, whereas it is inferior to the TSE sequence in the differential diagnosis of benign and malignantlesions.
