Improved and automated detection of papillary muscle infarction using joint bright- and black-blood LGE MRI
Motivation: Papillary muscle infarction (PMI) diagnosis is challenging because gold standard bright-blood MRI provides a poor contrast between damaged tissue and blood pool. Recent black-blood imaging overcomes this limitation by improving the scar-to-blood contrast. Goal(s): To develop a co-registered joint bright- and black-blood technology (SPOT) to improve visual PMI detection, while allowing an automated PMI detection algorithm (auto-PMI). Approach: 198 patients were imaged using both sequences. Number of patients with PMI were compared by two radiologists. Auto-PMI used SPOT images to detect PMI. Sensitivity was reported. Results: Radiologists detected significantly more PMI with SPOT. SPOT and auto-PMI outperformed the reference bright-blood sensitivity. Impact: As PMI is a key information for the prognosis of patients suffering from acute coronary syndrome such as myocardial infarction, improving the precision of its diagnosis using SPOT is crucial for better patient care.
