🔬 Dual-Source Photon-Counting CT for Morphological and Functional Assessment of Myocardial Bridging The evaluation of myocardial bridging (MB) has traditionally relied on morphological imaging, often underestimating its dynamic systolic behavior and potential hemodynamic impact. With the advent of dual-source Photon-Counting CT (PCCT), both morphological and functional characterizationof MB can now be approached within a single non-invasive acquisition. Key enabling features include: ⚙️ Ultra-high spatial resolution (0.1 mm) for accurate delineation of the intramyocardial segment and perivascular tissue interface. ⚡ High temporal resolution (~66 ms) through dual-source acquisition, allowing visualization of systolic compression (“milking”) and diastolic decompression across the cardiac cycle. 🌈 Spectral quantification capabilities, enabling iodine mapping and potentially dynamic perfusion analysis, to correlate luminal narrowing with downstream myocardial enhancement patterns. This integration of temporal, spatial, and spectral information positions PCCT as a unique tool for quantitative, phase-resolved assessment of myocardial bridging — offering insights previously limited to invasive or functional imaging modalities. #PhotonCountingCT #PCCT #DualSourceCT #MyocardialBridging #FunctionalCardiacImaging #SpectralImaging #CardiacCT #PrecisionCardiology #AdvancedImaging
