PDFAbstract
Objective To investigate the imaging characteristics of magnetic resonance imaging (MRI) sequence scanning for hepatocellular carcinoma (HCC) and the comparison with conventional multi-phase contrast-enhanced CT scan. Methods The clinical data of 52 patients with HCC in the hospital were analyzed retrospectively. All patients underwent MRI spin echo sequences T1WI, T2WI and fat suppression sequence (STIR) FS transverse scan and conventional multi-phase enhanced CT scan. Besides, they were confirmed by surgery or biopsy. The characteristics of MRI scans were analyzed. The diagnostic value of MRI and conventional multi-phase enhanced CT scan for HCC was compared. Results The MRI T1WI sequence mainly showed slightly lower signal. T2WI and STIR sequences mainly showed high signals. MRI could well show lesions of HCC and the diagnostic accuracy was 90.00%, while the diagnostic accuracy of multiphase contrast-enhanced CT was 86.67% (P>0.05). Conclusion MRI can better show the lesions of HCC, and the diagnostic accuracy is similar to that of multi-phase contrastenhanced CT, and can provide references for clinical treatment of HCC.
