Abstract

Objective: Alveolar echinococcosis (AE) is a rare life threating parasitic infection. Computed tomography perfusion (CTP) imaging has the potential to provide both quantitative and qualitative information about tissue perfusion characteristics.The purpose of this study is the examination of the characteristic features and feasibility of CTP in AE liver lesions.

 

Material and Methods:  CTP scanning was performed in 25 patients who had total of 35 lesions identified as AE of the liver. Blood flow (BF), blood volume (BV), portal venous perfusion (PVP), arterial liver perfusion (ALP), and hepatic perfusion indexes (HPI) were computed for background liver parenchyma and following components of each AE lesion.

 

Results:  The significant differences were detected between the perfusion values of the AE lesions and background liver tissue. The BV, BF, ALP and PVP values for all components of the AE liver lesions were significantly lower than the normal liver parenchyma (p<.01). 

 

Conclusions: We suggest that perfusion imaging can be used in AE of the liver. Thus, the quantitative knowledges of the perfusion parameters are obtained via CT perfusion imaging.
