Advanced Imaging in Cardiac Sarcoidosis

Area of Science:

• Cardiology
• Immunology
• Radiology

Background:

• Sarcoidosis is a chronic inflammatory disease of unknown cause.
• Cardiac involvement (cardiac sarcoidosis) can lead to severe outcomes, including heart failure and sudden death.
• Traditional diagnostic methods for cardiac sarcoidosis lack sensitivity.

Purpose of the Study:

• To review the role of advanced cardiac imaging in diagnosing and managing cardiac sarcoidosis.
• To highlight the theoretical and practical aspects of using MRI and PET for cardiac sarcoidosis evaluation.

Main Methods:

• Review of current literature on cardiac sarcoidosis diagnosis.
• Focus on the application of cardiac MRI (CMR) and Positron Emission Tomography (PET) imaging.
• Discussion of diagnostic criteria and risk stratification strategies.

Main Results:

• Advanced imaging modalities like CMR and PET demonstrate superior sensitivity compared to traditional methods.
• Cardiac MRI can detect myocardial inflammation and fibrosis characteristic of sarcoidosis.
• PET imaging, particularly with FDG, is valuable for assessing active inflammation.

Conclusions:

• Advanced cardiac imaging, including MRI and PET, is essential for the diagnosis of cardiac sarcoidosis.
• These imaging techniques aid in risk stratification and guiding treatment decisions.
• Early and accurate diagnosis through advanced imaging improves patient outcomes in cardiac sarcoidosis.
