目的
2
探讨基于团注追踪技术获得的头颈部血管成像(CTA)图像强化质量的影响因素,为定量控制图像质量提供依据。
方法
2
前瞻性收集2024年1—6月在我院行头颈部CTA检查的500例受检者的一般资料、注射参数、扫描参数以及图像强化质量分析数据。对受检者头颈部CTA图像强化质量进行综合评价,比较图像强化质量合格与不合格的受检者相关检查资料。采用多因素
Logistic
回归分析影响图像强化质量的独立因素。
结果
2
500例头颈部CTA图像中,图像强化质量合格262例,不合格238例。图像强化质量合格与不合格受检者的性别、身高、体质量、管电压、扫描方向、触发阈值、诊断延迟时间、碘对比剂浓度、碘对比剂用量、碘对比剂流速比较,差异有统计学意义(
P
<
0.05)。多因素
Logistic
分析显示:受检者为男性(95%
CI
:0.22~0.75,
P
=0.004)、体质量(95%
CI
:0.92~0.97,
P
<
0.01)、头-足方向扫描(95%
CI
:0.03~0.43,
P

CI
:1.21~1.34,
P
<
0.001)、碘对比剂流速(95%
CI
:0.14~0.59,
P
<
0.001)均为图像强化质量的独立影响因素;其中,碘对比剂用量(
β

结论
2
在头颈部CTA的团注追踪技术应用中,个体因素、扫描参数、注射方案是影响头颈部CTA图像强化质量阳性结果的关键控制要素。临床实践中,技师可通过整合人工智能辅助决策系统建立个性化扫描协议,实现精准、规范、个性化成像。
Objective
2
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
2
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
2
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
2
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.
