Abstract:Objective To explore the clinical application of 80 kV scanning combined with artificial intelligence (AI) optimization
technique in coronary computed tomography angiography (CCTA) in overweight patients. Methods In this prospective study, a total
of 60 overweight patients (BMI≥24 kg/m2) in our hospital from September 2020 to March 2021were randomly divided into group
A and group B, with 30 patients in each group. Group A used 120 kV scanning and ClearView+ iterative technique. 80 kV scanning
was used in group B, and group B was divided in to group B1 and group B2. Group B1 used ClearView+ iterative technique, and
group B2 used AI optimization technique. The subjective evaluation of images, CT values, noise, signal to noise ratio (SNR), contrast
to noise ratio (CNR) of coronary branch segments, and radiation dose were compared. Results The subjective evaluations were
significantly higher in both groups A and B2 than in group B1 (P<0.001), and there was no significant difference between group
A and group B2 (P>0.05). The CT values of group B were significantly higher than those of group A. The CNR of coronary artery
branches in group B2 were significantly higher than those in group A and group B1 (P<0.05). The radiation indexes in group B
were all significantly lower than in group A (P<0.001), and the effective dose (ED) was reduced by 75.18%. Conclusion The image
quality of 80 kV scanning combined with AI optimization technique in CCTA of overweight patients is consistent with the standard
120 kV scanning with lower radiation dose, which can be promoted in clinical application.
