A Study to Evaluate Advanced Ultrasound Techniques for Diagnosis of Giant Cell Arteritis


About this study

The purpose of this study is to evaluate shear wave data and vascular lumen size determined by Contrast-Enhanced Ultrasound (CEUS) in patients undergoing temporal artery biopsy, to determine the sensitivity and specificity of Shear Wave Elastography (SWE) and CEUS for the diagnosis of temporal arteritis, and to determine the impact of pre-operative ultrasound guided mapping on operative time required for temporal artery biopsy.
