Xenon-133 lung ventilation and perfusion scans were done preoperatively after cardiac catheterization and cineangiocardiography in 19 children; 6 had pulmonary atresia with an intact ventricular septum and hypoplastic right ventricle, 4 pulmonary atresia with associated complex univentricular heart, and 9 extreme Tetralogy of Fallot. The four patients with discrepancies in the sizes of the left...

Purpose Pulmonary ventilation and circulation dynamics are reflected on fluoroscopic images as changes in X-ray translucency. The purpose of this study was to investigate the feasibility of non-contrast functional imaging using a dynamic flat-panel detector (FPD). Methods Dynamic chest radiographs of 20 subjects (Abnormal, n=12; Normal, n=8) were obtained using the FPD system. Image analysis wa...

Perfusion lung imaging for diagnosing pulmonary embolism (PE) was introduced 50 y ago (1). At that time, it offered a noninvasive alternative to pulmonary angiography in patients with a clinical suspicion of PE. Because there are many causes of diminished regional blood flow in the lungs, particularly redistribution of blood flow away from regions with lung disease, the subsequent introduction ...

AIMS Coil protrusion into the left pulmonary artery (LPA) has been described after transcatheter closure of the patent ductus arteriosus (PDA). The possible impact of such a finding in lung perfusion has not been completely clarified. We evaluated Doppler flow velocities and lung perfusion in patients submitted to that procedure. METHODS After transcatheter closure of PDA with coils, 70 patie...

Planar lung ventilation/perfusion scintigraphy (V/P(PLANAR)) is a standard method for diagnosis of pulmonary embolism (PE). The goals of this study were to test whether the diagnostic information of ventilation/perfusion tomography (V/P(SPET)) applied in clinical routine might enhance information compared with V/P(PLANAR) and to streamline data processing for the demands of clinical routine. Th...

BACKGROUND An analysis of medical records of young females who were examined in our department during a five-year period (2005-2009) on suspicion of pulmonary embolism (PE) in relation to hormonal contraception (HC). MATERIAL AND METHODS The patient sample included 86 young females aged 15-25 (mean 21) years who underwent a ventilation/ perfusion scintigraphy (V/P scan). Seventeen of them wer...
