Abstract

Purpose: Numerous studies have already reported on the anatomy of the superficial temporal artery (STA) on dissection or imaging, and more specifically on CT angiography. However, few studies have reported on the possible variations that exist between readers in the assessment of certain anatomical parameters. The aim of this study was to investigate the reproducibility of different anatomical measurements of the superficial temporal artery with CT angiography.

Methods: Forty cranial iodine contrast-enhanced CT scans were searched in a retrospective monocentric study. Various anatomical categorical and quantitative measurements (more or less automatic) of the superficial temporal artery were assessed. To evaluate the inter-observer reproducibility of various anatomical measurements of the superficial temporal artery obtained through CT angiography, descriptive statistics, kappa statistics and intraclass correlation coefficients (ICC) were employed.

Results: Eighty STAs were analyzed independently by two readers. The kappa coefficient for determining the mode of STA termination was substantial (kappa = 0.782). The number of loops was mean 0.22 vs. 0.25 (p = 0.981; ICC = 0.701) and the number of kinks was mean 5.68vs5.64 (p = 0.876; ICC = 0.860). No significant difference was found between readers for the determination of the distance of the STA termination to different superficial landmark lines. No significant difference in the orientation angles of the STA and the frontal and parietal branches was found. Semi-automatic measurements of the length of the STA appeared (ICC > 0.7) reproducible whereas semi-automatic measurements (surface, perimeter, short diameter, large diameter) appeared statistically less reproducible (ICC < 0.5). These results must also be interpreted in the light of the spatial resolutions inherent in the CT angiography technique.

Conclusion: The present study provides information concerning the reproducibility of certain anatomical measurements of the superficial temporal artery in CT angiography.

颞浅动脉的放射解剖学测量：观察者间的可重复性研究。

目的：已经有大量的研究报道了颞浅动脉（STA）的解剖或成像，更具体地说是CT血管造影。然而，很少有研究报道在某些解剖参数的评估中，读卡器之间可能存在的差异。本研究的目的是探讨不同解剖测量的再现颞浅动脉与CT血管造影。方法：在一项回顾性单中心研究中检索了40张颅脑碘增强CT扫描。评估了颞浅动脉的各种解剖分类和定量测量（或多或少自动）。为了评估通过CT血管造影获得的各种颞浅动脉解剖测量的观察者间再现性，采用描述性统计、kappa统计和类内相关系数（ICC）。结果：80个sta由两位读者独立分析。决定STA终止方式的kappa系数很大（kappa = 0.782）。循环次数平均为0.22 vs. 0.25 (p = 0.981；ICC = 0.701)，扭结数平均为5.68vs5.64 (p = 0.876；icc = 0.860)。不同读卡者对STA终端到不同表面地标线距离的测定无显著差异。STA与额、顶叶支的定向角度无明显差异。半自动测量STA长度（ICC > 0.7）具有可重复性，而半自动测量（表面，周长，短直径，大直径）在统计学上具有较低的可重复性(ICC结论：本研究提供了有关CT血管造影中颞浅动脉某些解剖测量的可重复性的信息。

期刊介绍： Anatomy is a morphological science which cannot fail to interest the clinician. The practical application of anatomical research to clinical problems necessitates special adaptation and selectivity in choosing from numerous international works. Although there is a tendency to believe that meaningful advances in anatomy are unlikely, constant revision is necessary. Surgical and Radiologic Anatomy, the first international journal of Clinical anatomy has been created in this spirit. Its goal is to serve clinicians, regardless of speciality-physicians, surgeons, radiologists or other specialists-as an indispensable aid with which they can improve their knowledge of anatomy. Each issue includes: Original papers, review articles, articles on the anatomical bases of medical, surgical and radiological techniques, articles of normal radiologic anatomy, brief reviews of anatomical publications of clinical interest. Particular attention is given to high quality illustrations, which are indispensable for a better understanding of anatomical problems. Surgical and Radiologic Anatomy is a journal written by anatomists for clinicians with a special interest in anatomy.
