Dual Energy CT Evaluation Rabbit VX2 Transplantation In The Treatment Of Tumor Curative Effect

ObjectiveSiemens energy to use double after interventional therapy CT VX2 rabbit liver transplant tumor model scanned,Mainly discusses the tumor necrosis and cell survival lesions in the area. As the gold standard with pathological results, the result of the discussion with double degree, in the evaluation of liver energy CT interventional therapy efficacy of value after.Materials and MethodsDirect shap establish rabbit liver tumors of animal model selection, physiological condition is good, the growth of tumors, four rabbit line intervention operation, Parallel double energy CT scan, using dual energy liver OVERLAY workstation, measuring its focal area image, CT, And record its color order change (black, red, orange, red),For the gold standard in pathology, discuss the double energy in the evaluation of liver interventional therapy CT lesions area of necrosis and tumor cells to survive, and the preliminary evaluation value of energy in the evaluation of CT double after interventional therapy efficacy of hepatocellular carcinoma.All the data are divided into four groups levels, pathology results divided into four groups by statistical calculation, this, four levels of measurement accuracy and sensitivity and specificity, PV+, PV-ResultsAll data,312 for 80, the first black, First, the red for 60, Red order to 95, Orange order to 77, For the gold standard in pathology after pathological analysis, comparison, and one black color order accuracy for 88.8%, sensitivity and specificity for 94.1% 89.8%, PV+60%, PV-for 98.7%. Dark colored order accuracy for 74%, sensitivity and specificity for agency said 38.2%,88.3%, PV+for 56.7%, PV-78.2%. The red color order accuracy for 73.1%, sensitivity, specificity for 55.2%,82.1%, PV +for 61.1%, PV-for 78.3%. Orange colored order accuracy for 82.1%, sensitivity for 65.7%, specificity for 86.5%, for PV+57.1%, for PV-as high as 90.2%.ConclusionUse double energy CT scan liver, only once, can preliminarily reflect increasing scan within the lesions with cell survival tumor necrosis, And the tumor cells alive and CT image levels is obviously positive correlation changes for further treatment, provides valuable reference.
