Summary
Positron emission tomography/computed tomography (PET/CT) effectively identifies inflammatory aortitis. This dual-modality imaging enhances differentiation of vessel wall structures compared to PET or CT alone.
Area of Science:
- Nuclear Medicine
- Radiology
- Cardiovascular Imaging
Background:
- Fluorine-18 fluorodeoxyglucose (FDG) enables positron emission tomography (PET) for localizing hypermetabolic processes.
- Dual-modality PET/computed tomography (CT) systems integrate morphological and functional data.
Observation:
- Two patients with inflammatory aortitis presented with positive PET/CT findings.
- One patient had an inflammatory process involving the thoracolumbar aorta with an aneurysm.
- The other patient had a thoracic aortic aneurysm and significant FDG uptake.
Findings:
- PET/CT demonstrated hypermetabolism in both cases of inflammatory aortitis.
- The fused imaging provided detailed visualization of the affected aortic segments.
- FDG uptake correlated with the inflammatory activity within the vessel wall.
Implications:
- PET/CT offers advantages in diagnosing and monitoring inflammatory aortitis.
- It improves the differentiation of vessel wall structures compared to standalone PET or CT.
- This technique aids in assessing the extent and activity of aortitis, potentially guiding treatment decisions.
