Brief Summary:
The study aims at assessing diagnostic and therapeutic impact of Rubidium-82 PET in cardiac sarcoidosis.

Condition or disease Intervention/treatment Phase
Sarcoidosis Radiation: Rubidium PET Not Applicable

Detailed Description:
The presence of cardiac involvement is a serious complication of sarcoidosis. Early diagnosis is challenging since it relies on an array of clinical, biological and imaging abnormalities. Myocardial perfusion imaging with sestamibi is currently a major feature of the diagnosis, since it allows to evidence both microcirculatory impairments and scar. However, some technical limitations are inherent to SPECT, mainly poor spatial resolution and lack of attenuation correction, resulting in the absence of flow quantification. Rubidium-82 (Rb) PET proved to be more sensitive and specific than sestamibi SPECT in the diagnosis of coronary artery disease. Furthermore, it allows noninvasive measurement of coronary flow reserve. Finally, it exposes patients to lower radiation dose than SPECT. Therefore, Rb PET may help to better identify cardiac involvement of sarcoidosis, and hence to better select those patients who require high-dose steroids.

Primary Outcome Measures :
  1. percentage of patient who has two different diagnostic and therapeutic attitude before knowing Rubidium-82 PET result and after knowing Rubidium-82 PET result [ Time Frame: 60 days ]
    to assess diagnostic and therapeutic impacts of myocardial perfusion analysis with Rubidium-82 PET in cardiac sarcoidosis.


Secondary Outcome Measures :
  1. Analysis of the cost for the use of Sestamibi SPECT and Rb-PET as MPI agents in cardiac sarcoidosis. [ Time Frame: 9 months ]
    to compare the cost between the two exams and the health-economic impact of Sestamibi SPECT and Rb-PET as MPI agents in cardiac sarcoidosis.
