Clinical utility of 18F-FDG PET/CT in patients with microscopic polyangiitis and interstitial lung disease: a retrospective cohort study

Key Points

• To evaluate the clinical utility of 18F-FDG PET/CT in detecting interstitial lung disease (ILD) in patients with microscopic polyangiitis (MPA).
• Retrospective cohort design
• Analysis of patients with microscopic polyangiitis
• Assessment of 18F-FDG PET/CT imaging outcomes for ILD detection
• Evaluation of specificity and sensitivity of the imaging technique
• 18F-FDG PET/CT shows high specificity for detecting ILD in MPA patients
• Limited sensitivity of the imaging modality restricts its use as a screening tool
• The imaging technique is suggested for its prognostic value in MPA-associated ILD
