Temporal Arteritis Menu. Temporal arteritis is a form of vasculitis (inflammation of the blood vessels). In temporal arteritis, also known as giant cell arteritis or Horton's arteritis, the temporal arteries (the blood vessels near the temples), which supply blood from the heart to the scalp, are inflamed (swollen) and constricted (narrowed).Does MRI show deep temporal artery involvement in giant cell arteritis?
In a study of deep temporal artery and temporalis muscle involvement in patients with giant cell arteritis, MRI visualized changes in both the temporalis muscle and the deep temporal artery, and moderate correlation of clinical symptoms with MRI results was observed.Does ctcta detect superficial temporal artery abnormalities?
CTA has an accuracy of 78.6%, sensitivity of 71.4%, and a specificity of 85.7% for GCA. Conclusions- CTA detects superficial temporal artery abnormalities in GCA. This may facilitate early diagnosis and prompt implementation of potentially sight-saving and stroke-preventing treatment.What tests are done to diagnose temporal arteritis?
If temporal arteritis is suspected, the doctor may order a biopsy, in which a small piece of the artery is removed and examined for evidence of inflammation within the vessels. Other tests that are sometimes necessary include:
