Inflammatory cardiomyopathy (ICMP) needs to be diagnosed early, and cardiac T1 and T2 mapping both have been shown to increase the accuracy of ICMP diagnosis. Cardiac magnetic resonance fingerprinting (cMRF) can be used to robustly acquire both maps in a single breath-hold, so the goal of this preliminary study was to compare the performance of cMRF and routine parameter mapping in patients with suspected ICMP, including those with implantable cardioverter-defibrillators (ICDs), which often cause significant artifacts. The relaxation times in 24 patients were similar in cMRF and routine mapping, while cMRF may have superior performance in patients with an ICD.
