Differential diagnosis of hepatocellular carcinoma and cavernous hemangioma. Possibility of progress evaluated by magnetic resonance imaging

Journal Article:

Abstract

In 35 cases of hepatocellular carcinoma (HCC) and 25 cases of cavernous hemangioma (CH) of the liver, magnetic resonance (MR) spin echo images were obtained using a 0.35 tesla superconducting MR imager (Siemens, Magnetom). On the images with a TR (repetition time) of 1600 msec and a TE (echo delay time) of 70 msec, all tumors appeared as high intensity areas, and there, Tumor/Liver intensity ratio (T/L) was calculated. T/sub 1/ (longitudinal relaxation time) and T/sub 2/ (transverse relaxation time) of the lesions were also calculated from the images with two TR (400 and 1600 msec) and two TE (35 and 70 msec). The T/sub 1/(940 +- 180 msec), T/sub 2/(110 +- 40 msec) and T/L(2.2 +- 0.4) of CH were significantly higher (p<0.001) than the T/sub 1/(660 +- 100 msec), T/sub 2/(60+-8 msec) and T/L(1.5 +- 0.4) of HCC, respectively. There was no correlation between these values and tumor size on MR, which ranged from 1.5 to 10 cm in diameter. All of CH satisfied the condition; T/sub 1/>660 msec, T/sub 2/>54 msec and T/L>1.6. In contrast, 73% of HCC did not satisfy the above condition. Our results suggest that use of MR will improve the accuracy of the  More>>
