Introduction: Quantitative computed tomography (qCT) provides detailed spatial assessments of lung structure and function, while electrical impedance tomography (EIT) offers high temporal resolution for analyzing breathing patterns but lacks structural detail. This study investigates the correlation between qCT-based spatial variables and EIT-based temporal signals to elucidate the physiological relationships between these two modalities.
Methods: Six participants with asthma underwent pulmonary function tests (PFTs) before and after bronchodilator inhalation.

Aims: For many years, visual assessment has been the mainstay of detecting obstructive coronary artery disease (CAD) by stress perfusion cardiovascular magnetic resonance (S-CMR). Recently, fully automated quantitative assessment of myocardial blood flow (MBF) has been introduced. The value of MBF quantification in patients with coronary chronic total occlusion (CTO) is unknown.

Some patients with heart failure with preserved ejection fraction (HFpEF) have demonstrated evidence of exercise-induced arterial hypoxaemia (EIAH). However, EIAH was not quantified using , , and measurements as previously conducted in healthy adults nor was EIAH quantified alongside simultaneous measurements of pulmonary vascular pressures, cardiorespiratory responses, or dyspnoea on exertion (DOE) in these patients. Given the effects of hypoxaemia on pulmonary vasoconstriction, cardiorespiratory responses, and DOE, we tested the hypothesis that patients with HFpEF and EIAH (EIAH) would demonstrate higher pulmonary vascular pressures, worse oxygen uptake, and greater DOE compared with patients without EIAH (EIAH).
