Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

PET scanning (positron emission tomography) is a well-established technique used to identify areas of interest within the body. It involves injecting a radioactive tracer which highlights abnormal areas. It has recently been combined with CT (computed tomography) and MRI (magnetic resonance imaging) scanning to more accurately identify abnormalities within the heart. Cardiac sarcoidosis, a condition which causes scarring and inflammation within the heart muscle, is of particular interest.

The study makes use of hybrid PET/MR scanning using a designated scanner which enables PET scanning combined with MRI scanning. This will allow imaging of abnormal areas within the heart in this condition alongside treatment regimens in a way which hasn't been done before. If successful, this imaging method will play a key role in diagnosing, quantifying and monitoring these conditions.

All participants will undergo PET scanning, where a radioactive tracer is injected into a vein before the scan. The radioactive substance only lasts for a short time and is safe, passed out of the body in urine. The scan will be performed twice; once before treatment and once after treatment has been established. A cohort of healthy volunteers will undergo scanning in exactly the same way to enable us to compare the results with hearts of people who don't have cardiac sarcoidosis.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

NON_RANDOMIZED

Intervention Model

PARALLEL

Patients and healthy subjects will be allocated in a non-randomised fashion to either corticosteroid or control arms, for parallel comparison within the two groups. The corticosteroid is recognised treatment for the condition and is being used to observe the impact on diagnostic imaging; no treatment effects are being studied or are endpoints of the study (i.e. the study is not a clinical trial of treatment in cardiac sarcoidosis with corticosteroid).
