Abstract

Objective To analyze the CT and MRI features of hepatic hemangioma, and to explore the quality of hepatic hemangioma by CT and MRI images. Methods A total of 41 patients with hepatic hemangioma diagnosed by our hospital from May 2015 to December 2016 were selected. The patients were examined by CT and MRI. The imaging data and clinical data were collected and analyzed. The imaging findings of hepatic hemangioma in CT and MRI were analyzed, and the results of MRI and CT examination were compared. Results A total of 47 lesions were found in 41 patients, 37 cases were single lesions, 4 cases were multiple lesions, 95.74% (45/47) of CT scan and 97.87 % (46/47) of MRI. No significant difference was detected in the detection rate of the two kinds of examination methods (P>0.05); 30 cases (73.17%) patients with CT scan images of classical hepatic hemangioma image characteristics, enhanced process was "fast forward slow out", gradually "centripetal enhancement". The other 4 patients (9.75%) had no typical image. 39 cases (95.12%) patients with the lesions were round or lobulated, clear boundary, long T1, long T2 signal changes, which were gradually increased with prolonging of echo time, as the "light bulb" sign. Conclusion CT and MRI have high detection rate of hepatic hemangioma, which can show the typical imaging features of hepatic hemangioma, and MRI shows better for atypical hepatic hemangioma.
