Positron Emission Tomography–Computed Tomography versus Magnetic Resonance Imaging for Adult Patients with Suspected Cardiac Sarcoidosis: Clinical Utility, Cost-Effectiveness, and Diagnostic Accuracy

Question

1. What is the clinical utility of positron emission tomography–computed tomography compared to magnetic resonance imaging in patients with suspected active cardiac sarcoidosis?
2. What is the cost-effectiveness of positron emission tomography–computed tomography compared to magnetic resonance imaging in patients with suspected active cardiac sarcoidosis?
3. What is the diagnostic accuracy of positron emission tomography–computed tomography in patients with suspected active cardiac sarcoidosis?

Key Message

One non-randomized study was identified regarding the clinical utility of positron emission tomography–computed tomography compared to magnetic resonance imaging in patients with suspected active cardiac sarcoidosis. Furthermore, two systematic reviews with meta-analysis and eight non-randomized studies were identified regarding the diagnostic accuracy of positron emission tomography–computed tomography in patients with suspected active cardiac sarcoidosis. No relevant literature was identified regarding the cost-effectiveness of positron emission tomography–computed tomography compared to magnetic resonance imaging in patients with suspected active cardiac sarcoidosis.
