Insights
Non-invasive imaging is crucial for diagnosing large vessel vasculitis. While color-coded sonography, CT, MRI, and positron emission tomography (PET) have roles, the diagnostic benefit of combined PET-CT for assessing disease activity and therapy control requires further investigation.
Area of Science:
- Vascular Medicine
- Diagnostic Imaging
- Rheumatology
Abstract:
At present non-invasive imaging is of paramount importance in the diagnostic evaluation of large vessel vasculitis. For evaluation of the cranial and extracranial aortic branches color coded sonography is the method of choice, whereas CT and MRI are useful in assessing the thoracic aorta. Positron emission tomography (PET) imaging allows direct visualization of the extent of vascular inflammation. To date the diagnostic benefit of combined PET and morphological imaging (PET-CT) as well as the value of imaging procedures in order to assess disease activity and therapy control remain unclear.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
