Abstract: Objective To evaluate the sensitivity of computed tomography during splenoportographg (CTSP) in the diagnosis of hepatic metastases. Materials and Methods CTSP was performed in 22 cases of hepatic metastatic tumor with dynamic sequence contrast scanning, and the results were compared with those of B ultrasound, precontrast CT and contrast-enhanced CT scans. Results The total sensitivity rates of ultrasonic, precontrast CT, contrast-enhanced CT and CTSP scans were 57.7%, 60.4%, 68.9% and 91.7%, respectively. The sensitivity rates for small lesions (f≤1cm) were 32.7%, 38.6%, 48.3% and 91.8% respectively, showing significant difference between CTSP and the other methods (P<0.01). When the lesions were larger than 1 cm, the 4 methods were not significantly different in making diagnoses (P> 0.05). Conclusion CTSP is sensitive in detecting the hepatic metastatic tumor, providing accurate orientation for metastatic deposits, and therefore facilitating the best imaging determination of the target for surgical treatment.
