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.
