OBJECTIVES The purpose of this study was to evaluate the influence of pulmonary regurgitation inequality on differential perfusion of the lungs in tetralogy of Fallot (TOF) after repair. BACKGROUND Asymmetry of lung perfusion is one of the best predictors of outcome in TOF after repair. A recent phase-contrast magnetic resonance imaging (PC-MRI) study found prominent regurgitation inequality ...

The cover image is based on the Research Article Assessing cardiac mechanical dyssynchrony in left bundle branch area pacing and right ventricular septal using myocardial perfusion scintigraphy acute phase of pacemaker implantation by Keisuke Miyajima MD et al., https://doi.org/10.1111/jce.15609.

OBJECTIVE To highlight the importance of the lung ventilation scintigraphy (LVS) to study the regional distribution of lung ventilation and to describe most frequent abnormal patterns of lung ventilation distribution obtained by this technique in COPD and to compare the information obtained by LVS with the that obtained by traditional lung function tests. MATERIAL AND METHODS The research was...

introduction: the aim of this study was to evaluate the impact of measurement of coronary artery calcification score (cac) in patients with suspected coronary artery disease (cad) and a normal myocardial perfusion scan. methods: in a prospective study we measured the calcium score of 74 patients (29 m, 45 f, mean age 58.7 (m) and 64.4 (f)) with suspicion of cad and a normal perfusion scan. in ...

Background Myocardial ischaemic burden assessed by myocardial perfusion scintigraphy (MPS) is commonly used to riskstratify patients with suspected coronary artery disease (CAD). Accurate estimation of ischaemic burden by CMR with two-dimensional imaging is limited by incomplete myocardial coverage to a small number (usually three) of non-contiguous sections. The aim of this study was to compar...

Pulmonary embolism (PE) is a preventable cause of morbidity and mortality which needs prompt recognition. Ventilation-perfusion (V/Q) scan is a well-established diagnostic test for evaluation of suspected PE. We report a 32-year-old woman with history of rheumatologic disease and acute dyspnea, who was referred for V/Q scintigraphy. The planar images revealed multiple mismatched defects through...
