[Revolution CT hepatic perfusion imaging assessment of peripheral infiltration zone of hepatic alveolar echinococcosis].

Objective: To analyze the blood supply and metabolism in the marginal area of foci of hepatic alveolar echinococcosis by quantitative perfusion parameters.

Methods: Thirty patients with hepatic alveolar echinococcosis were scanned with the Revolution CT and the images were analyzed. The perfusion parameters, such as the bloodflow (BF), time to peak (TTP), blood volume (BV), mean transit time (MTT) and hepatic arterial fraction (HAF) were compared among different groups.

[Imaging analysis of 79 cases of hepatic echinococcosis].

Objective: To analyze the imaging manifestations of 79 cases of hepatic echinococcosis retrospectively, so as to provide evidences for improving the diagnosis and differential diagnosis of the disease.

Methods: Seventy-nine patients with hepatic echinococcosis who underwent imaging examinations and pathologic confirmation in Qinghai Provincial People's Hospital from 2014 to 2017 were chosen as the investigation objects, and the data of their medical records and imaging manifestations were collected and analyzed.

Results: Among the 79 cases of hepatic echinococcosis, 57 were suffered from cystic echinococcosis (CE) and 22 were suffered from alveolar echinococcosis (AE) .

[Value of CT imaging of inferior vena cava and hepatic vein in patients with hepatic cystic echinococcosis].

Objective: To evaluate the accuracy of CT imaging of inferior vena cava and hepatic vein in patients with hepatic cystic echinococcosis.

Methods: A total of 100 patients with hepatic cystic echinococcosis were given triple-phase abdominal CT scan, and the reconstructed images of the inferior vena cava and hepatic vein were obtained and compared to the real situation during the surgical operation. The reliability of the CT evaluation of the echinococcus cyst lesion invading inferior vena cava and hepatic vein was analyzed.
