Abstract Objective To discuss the effect of double low technology combined with individualized injection on image quality of abdominal enhanced CT in adults and its safety. Methods The clinical and imaging data of 231 patients who underwent abdominal enhanced CT in the Department of Radiology, Wuxi No.2 people's Hospital from June 2019 to June 2022 were retrospectively analyzed. They were divided into two groups according to the use of different iodine contrast agents. 123 patients were treated with isotonic contrast medium (iodoxalol 270mgI/ml) as isotonic group, while 108 patients with subhyperosmotic contrast medium (320 mgI/ml) as subhyperosmotic group. The clinical data of the two groups were compared, the image quality was evaluated subjectively and objectively, and the radiation dose of CT and the indexes of liver and kidney function before and after CT were compared and analyzed. Results The CT values of abdominal aorta and portal vein in the isotonic group were significantly higher than those in the subhypertonic group (P<0.05). The hepatic arteriovenous noise in the isotonic group was significantly lower than that in the subhypertonic group (P<0.05). There was no significant difference in sex, age, height, weight or radiation dose between the two groups (P>0.05). There was no significant difference in liver plain scan, arteriovenous phase CT value and absolute enhancement value, arterial phase abdominal aorta and portal vein phase portal vein noise, vertical spinal muscle arteriovenous phase CT value or noise between the two groups (P>0.05). There was no significant difference in signal-to-noise ratio, contrast-to-noise ratio, liver function (glutamic pyruvic transaminase, glutamic oxaloacetic transaminase), or renal function (urea nitrogen, serum creatinine) between the two groups (P>0.05). The subjective evaluation results of image quality were highly consistent between the doctors. Conclusions The iso-osmotic injection of double-low technique combined with individualized injection for abdominal enhanced CT can obtain higher degree of arteriovenous enhancement and lower image noise, so it is suitable for vascular reconstruction after CT.
