Temporal artery biopsy (TAB) is frequently still required in patients with suspected cranial giant cell arteritis (GCA). The literature on the performance characteristics of TAB versus imaging is conflicting, and several meta-analyses suggest that TAB is more sensitive than ultrasound. False-positive ultrasound results can occur. Also, diseases that mimic the symptoms, signs or imaging characteristics of GCA may only be revealed on pathology.
颞动脉活检（TAB）在疑似颅 giant cell arteritis（GCA）患者中仍经常需要。关于 TAB 与影像学检查的表现特征的文献存在争议，几项荟萃分析表明 TAB 比超声更敏感。超声结果也可能出现假阳性。此外，可能仅在病理学上才能发现与 GCA 的症状、体征或影像学特征相似的疾病。
