Cardiac sarcoidosis (CS) mimics cardiomyopathy, posing diagnostic challenges. Advanced imaging like MRI and PET/CT aids in accurate diagnosis and prognosis of this condition.
Area of Science:
- Cardiology
- Medical Imaging
Background:
- Cardiac sarcoidosis (CS) presents diversely, mimicking other cardiomyopathies.
- Prevalence estimates for CS vary widely (2.3%–29.9%) in cardiomyopathy/atrioventricular block patients.
- Accurate diagnosis of CS is difficult due to disease progression and lack of a gold standard.
Purpose of the Study:
- To review the role of advanced imaging in diagnosing and prognosticating cardiac sarcoidosis.
- To highlight the utility of cardiac magnetic resonance imaging (CMR) and positron emission tomography/computed tomography (PET/CT).
Main Methods:
- Review of contemporary literature on advanced cardiac imaging for CS.
- Focus on cardiac magnetic resonance imaging (CMR) and positron emission tomography/computed tomography (PET/CT) applications.
Main Results:
- Advanced imaging modalities offer improved diagnostic capabilities for CS.
- CMR and PET/CT provide valuable prognostic information in patients with CS.
Conclusions:
- Current diagnostic criteria for CS have limitations in sensitivity and specificity.
- Advanced imaging, including CMR and PET/CT, is crucial for improving CS diagnosis and management.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for...
