ABSTRACT

Introduction: We compare the breath-hold fast recovery fast spin echo (BHFRFSE) T2-weighted and non-breath-hold fast spin echo (NBHFSE) T2-weighted sequences in image quality and lesion characterisation of focal liver lesions.

Materials and Methods: Fat-suppressed T2-weighted magnetic resonance (MR) images obtained with the 2 sequences (BHFRFSE and NBHFSE) in 79 patients with 113 liver lesions were analysed retrospectively. The image quality and nature of the lesions were evaluated by 2 experienced radiologists.

Results: Based on receiver operating characteristic curve analysis, lesion characterisation was comparable for both sequences. The image quality of BHFRFSE was significantly better than that of NBHFSE. The NBHFSE missed 4 malignant lesions while BHFRFSE missed 2 malignant lesions.

Conclusion: BHFRFSE performs similarly to NBHFSE in image quality and liver lesion characterisation.


T2-weighted magnetic resonance (MR) imaging is an important sequence for characterisation of focal liver lesion. Accurate characterisation of benign lesions, such as haemangioma or cyst, is important to prevent unnecessary procedure or surgery.
