Analysis on factors affecting the enhancement quality of head and neck CTA images based on bolus-tracking technology
摘要
Abstract
Objective To explore the factors affecting the enhancement quality of head and neck computed tomography angiography(CTA)images based on bolus-tracking technology,and provide a basis for quantitatively controlling image quality.Methods The general information,injection parameters,scanning parameters and analysis data of enhancement quality of images of 500 subjects who underwent head and neck CTA examinations in our hospital from January to June 2024 were prospectively collected.A comprehensive evaluation of enhancement quality of head and neck CTA images of the examinees was conducted,and the relevant examination data of the examinees with qualified and unqualified enhancement quality of images were compared.Multivariate Logistic regression analysis was used to analyze the independent factors influencing the enhancement quality of image.Results Among 500 CTA images of head and neck,262 cases had qualified enhancement quality of images and 238 cases were unqualified.There were statistically significant differences in gender,height,body weight,tube voltage,scanning direction,trigger threshold,diagnostic delay time,iodine contrast agent concentration,iodine contrast agent dosage,and iodine contrast agent flow rate between the examinees with qualified and unqualified enhancement quality of images(P<0.05).Multivariate Logistic analysis showed that the examinees were male(95%CI:0.22 to 0.75,P=0.004),body weight(95%CI:0.92 to 0.97,P<0.01),and head-foot direction scanning(95%CI:0.03 to 0.43,P=0.002),diagnostic delay time(95%CI:0.44 to 0.92,P=0.017),iodine contrast agent dosage(95%CI:1.21 to 1.34,P<0.001),iodine contrast agent flow rate(95%CI:0.14 to 0.59,P<0.001)were all the independent influencing factors of enhancement quality of image;Among them,the iodine contrast agent dosage(β=0.24,OR=1.27)was positively correlated with the enhancement quality of image,the examinees were male(β=-0.89,OR=0.41),body weight(β=-0.06,OR=0.94),head-foot direction scanning(β=-2.23,OR=0.11),diagnostic delay time(β=-0.45,OR=0.64),and iodine contrast agent flow rate(β=-1.26,OR=0.28)were negatively correlated with the enhancement quality of image.Conclusion In the application of bolus-tracking technology for head and neck CTA,individual factors,scanning parameters,and injection regimens are the key control elements that affect the positive results of enhancement quality of head and neck CTA images.In clinical practice,technicians can establish personalized scanning protocols by integrating artificial intelligence-assisted decision-making systems to achieve precise,standardized and personalized imaging.关键词
