Abstract: Purpose The PHC was examined by CTSP and US. We compared its diagnosisvaslue .Materials aild Methods 43 patients with PHC were examined by US and computertomography during splenoportography(CTSP)and were carried out with dynamic scanner in portalvenous phase. The number of the detected lesions,the sensitivity and accuracy of characterizationwere statistically calculated and analysed .Results 106 lesions were seen in 43 patients withPHC,The sensitivity in US and CTSP was respectively 63.2% and 91 .5%(p＜0.01).The significantdifference of the accuracy of characterizaton was also found between CTSP(96.9%)and US(79.1%).Conclusion The CTSP can improve considerably the sellsitivity of PHC and was animportant method of early diagnosis PHC.
