Overview

PET scan is useful in diagnosis of Takayasu’s arteritis by providing valuable information about cellular activity within an inflamed arterial wall even before morphologic changes on other imaging studies. In patients with TA, MRA shares the similar features of TA with CTA images, and can be used in the diagnosis and follow-up of patients undergoing treatment, especially those who are young.

Other Imaging Findings

Positron emission tomography (PET) scan

PET scan is useful in diagnosis of Takayasu’s arteritis by providing valuable information about cellular activity within an inflamed arterial wall even before morphologic changes on other imaging studies.^[1]

Magnetic resonance angiography (MRA)

In patients with TA, MRA shares the similar features of TA with CTA images, and can be used in the diagnosis and follow-up of patients undergoing treatment, especially those who are young.^[2]
The disadvantages of MRA are the contraindications associated with:
- Electronic devices
- Intraluminal stent implantation
- Claustrophobia
