 note = {Purpose Cardiac sarcoidosis (CS) is a cause of conduction
system disease (CSD). 18F-Fluorodeoxyglucose-positron
emission tomography (FDG PET) and cardiac magnetic resonance
(CMR) are used for detection of CS. The relative diagnostic
value of these has not been well studied. The aimwas to
compare these imaging modalities in this population.
Methods We recruited steroid-naive patients with newly diagnosed
CSD due to CS. All CS patients underwent both imaging
studies within 12 weeks of each other. Patients were
classified into two groups: group A with chronic mild CSD
(right bundle branch block and/or axis deviation), and group B
with new-onset atrioventricular block (AVB, Mobitz type II or
third-degree AVB).
Results Thirty patients were included. Positive findings on
both imaging studies were seen in 72 % of patients (13/18)
in group A and in 58 % of patients (7/12) in group B. The
remainder (28 %) of the patients in group Awere positive only
on CMR. Of the patients in group B, 8 % were positive only
on CMR and 33 % were positive only on FDG PET. Patients},
