摘要
低回声光晕是巨细胞动脉炎（GCA）的典型超声检查结果，但它可能是动脉硬化引起的假阳性。因此，我们重点研究了 GCA 病变的节段分布，将长轴图像中的管腔不规则性定义为串珠征，并考察了其诊断能力。结果，低回声晕和串珠征的 C 统计量（1.00 对 0.89）优于单纯低回声晕。综上所述，在常规低回声晕的基础上增加串珠征，可提高 GCA 的诊断能力。
A Novel Ultrasound Finding for the Diagnosis of Giant Cell Arteritis: Comparison With Temporal Artery Biopsy Findings.
Hypoechoic halo is a typical ultrasound finding in giant cell arteritis (GCA), but it may be a false positive due to arteriosclerosis. Therefore, we focused on the segmental distribution of GCA lesions, defined the luminal irregularity in long-axis images as the string of beads sign, and examined its diagnostic ability. As a result, the C-statistic of hypoechoic halo and string of beads sign was better than that of hypoechoic halo alone (1.00 vs. 0.89). Based on the above, the diagnostic ability of GCA can be improved by adding the string of beads sign to the conventional hypoechoic halo.
期刊介绍：
The Journal of Clinical Ultrasound (JCU) is an international journal dedicated to the worldwide dissemination of scientific information on diagnostic and therapeutic applications of medical sonography.
The scope of the journal includes--but is not limited to--the following areas: sonography of the gastrointestinal tract, genitourinary tract, vascular system, nervous system, head and neck, chest, breast, musculoskeletal system, and other superficial structures; Doppler applications; obstetric and pediatric applications; and interventional sonography. Studies comparing sonography with other imaging modalities are encouraged, as are studies evaluating the economic impact of sonography. Also within the journal''s scope are innovations and improvements in instrumentation and examination techniques and the use of contrast agents.
JCU publishes original research articles, case reports, pictorial essays, technical notes, and letters to the editor. The journal is also dedicated to being an educational resource for its readers, through the publication of review articles and various scientific contributions from members of the editorial board and other world-renowned experts in sonography.
