Compares photon-counting CT and V/Q SPECT for assessing lobar perfusion in chronic thromboembolic pulmonary hypertension, suggesting improved diagnostics.
Question PCCT perfusion may address the unmet need for a combined functional and anatomical evaluation of CTEPH in a single examination. Findings PCCT showed strong correlation with V/Q-SPECT for lobar and whole-lung perfusion, with minimal bias and consistent quantitative agreement. Clinical relevance PCCT enables simultaneous high-resolution assessment of perfusion, vasculature, and parenchyma, potentially improving diagnostic confidence and streamlining CTEPH work-up in clinical practice.
