This imaging technique is useful in cardiac sarcoidosis for the identification of possible areas with active inflammatory processes; an algorithm has been proposed as a response test to treatment [3]. As a diagnostic guide, a meta-analysis concluded 89% sensibility and 78% specificity; however, these results should be viewed with caution and with the diagnostic criteria used as a pattern [26].

Advanced cardiovascular imaging is advised in the following clinical contexts [27]: Patients with extracardiac compromise


• One or more of the following echocardiographic anomalies: anomalies in the regional movement of a wall, ventricular aneurysm, thinning of the interventricular septum (basal segment), and ejection fraction of the left ventricle below 50%
