title: [Pilot study on clinical application of hepatic perfusion with multi-slice spiral CT].
abstract: OBJECTIVE
  To research the value of hepatic perfusion with multi-slice spiral CT in the diagnosis of liver diseases.
  
  
  METHODS
  Among the 48 patients undergone dynamic CT of the liver, 20 were volunteers without hepatic disorder, 17 with cirrhosis, 11 suffered from hepatic cancer. The perfusion indexes were calculated and compared.
  
  
  RESULTS
  (1) Compared with the control group, HPP (ml/min/ml), PPI and HPP/HAP of patients with cirrhosis were significant lower (HPP: 0.49+/-0.19 vs 0.60+/-0.16, P=0.038; PPI: 0.58+/-0.14 vs 0.67+/-0.06, P=0.015; HPP/HAP: 1.63+/-0.87 vs 2.12+/-0.65, P=0.04), whereas HPI was higher (0.42+/-0.14 vs 0.33+/-0.06, P= 0.015), which indicated the decrease of portal inflow and the increase of arterial inflow in cirrhosis patients. (2) Patients with hepatic cancer got a significant higher average HAP than that in volunteers and cirrhosis patients (F=11.71, P<0.001), while their HPP and HPP/HAP showed significant declining (F=22.84, P=0.0001; F=20.67, P<0.0001, respectively), which implied that hepatic cancer was mainly supplied by artery.
  
  
  CONCLUSIONS
  Hepatic perfusion with multi-slice spiral CT is an non-invasive technique to evaluate the arterial and portal inflow separately, which can inflect the hemodynamic change of the lesion by the perfusion indexes, and identify the condition of the tissue round the lesion prior to morphologic change. This method shows important value of diagnosis and differential diagnosis in hepatic diseases.
