| With the socio-economic development of China and the expansion of pet breeding,the level of pet medical care has developed and iterated in leaps and bounds.The rapid development of medical devices has led to many human medical techniques becoming evident and applied in pet medical care,and Computed Tomography(CT)is now beginning to gain initial application and rapid popularization in pet medicine due to its fast diagnostic speed,high accuracy.And wide application.This paper describes the development and technology of CT,measures the normal CT values of the main organs of the canine abdominal cavity,analyzes its correlation with dog breed,sex,age,and weight,and compiles typical cases of its application in the diagnosis of canine spleen,kidney,and liver diseases to provide ideas and references for the diagnosis of canine abdominal cavity diseases.Fifty-three dogs with healthy study organ status were screened from 456 computed tomography cases,and medical statistical analysis was performed by applying ROI measures with 95%confidence intervals and SPSS.The results show that the normal state CT values of the liver in dogs were 59.79 ± 1.55 HU(P=0.887);the CT value of the pancreas was 50.04 ± 1.18 HU(P=0.529);the CT value of the spleen was 60.04 ± 1.14 HU(P=0.806);the CT value of the adrenal gland was27.02 ± 1.00 HU(P=0.127);the CT value of the renal cortex was 35.93 ± 1.37 HU(P=0.312);renal medulla CT value was 30.27 ± 1.00 HU(P=0.882).The CT values of the main parenchymal organs of the abdominal cavity of Chinese Field Dogs,Poodles,and crossbred dogs;males and females were simultaneously obtained according to breed and sex classification using the same method,and the results of each group were subjected to t-test,and all results are at the P>0.05 with no significant differences in the CT values of each organ.The effects of age and body weight on the CT values of the major abdominal parenchymal organs were analyzed separately,and the results showed no correlation.We participated in and collected data of 96 cases of CT values in clinical application,among which 34 cases of hepatobiliary-related diseases,accounting for 35.4% of the total number of canine abdominal diseases;18 cases of spleen-related diseases,accounting for 18.8% of the total number of canine abdominal diseases;24 cases of kidney-related diseases,accounting for 25.0% of the total number of canine abdominal diseases;4 cases of pancreas-related diseases,accounting for 4.3% of the total number of canine abdominal diseases;and 16 cases of other abdominal diseases,accounting for 16.5% of the total number of abdominal diseases in dogs.Typical cases of spleen,kidney and liver diseases were selected for analysis and discussion,indicating that CT value is an effective quantitative parameter to improve the diagnostic efficiency and assist in the diagnosis of lesion nature. |
