Relationship Between the Volume of Spleen and Zebra Enhancement Pattern on CTAP / 实用放射学杂志

ABSTRACT

Objective To evaluate the relationship between the volume of spleen and zebra enhancement pattern on CTAP(CT arterial portography).Methods Total 219 cases of hepatocellular carcinoma underwent CTAP were retrospectively analyzed.The patients were divided into three groups according to the CTAP enhancement patternsgroup l,patchy heterogeneous enhancement(zebra pattern);group 2,homogeneous enhancement with remarkable hypodensity of the liver parenchyma(hypodensity pattern);group 3,homogeneous enhancement with definitive contrast(normal pattern).The volume of spleen was measured based on CT findings and compared among the groups.Results In the total 219 cases,there were 10 cases showing zebra enhancement pattern(4.6%),16 cases of homogeneous hypodensity(7.3%)and 193 of normal enhancement pattern(88.1%).The average volumes of the spleen of the three groups were (588.3?331.5) cm 3,(883.2?296.5) cm 3 and (474.4?275.0) cm 3,respectively.There was no significant difference of the splenic volume between groups 1 and 3,and the difference between groups 2 and 3 was significant.Conclusion There is no definitive relationship between the zebra enhancement pattern on CTAP and the volume of spleen,while the homogeneous hypodense enhancement is positively and significantly correlated with the volume of spleen.
