The past decade has seen a shift in the imaging paradigm for acute pulmonary embolism (PE) from a combination of clinical acumen, ventilation-perfusion scintigraphy, and conventional pulmonary angiography to computed tomographic pulmonary angiography (CTPA). The ability to perform CT rapidly with direct visualization of thrombi allows for rapid and reliable diagnosis or exclusion of PE in the v...

BACKGROUND Spinal artery ischemia is a rare but serious complication of embolization for treatment of hemoptysis. When the spinal artery is visualized at angiography, embolization should not be performed. However, it has been reported that spinal artery feeders are not visible on angiography in patients with developing spinal infarction. CASE REPORT A 70-year-old man with a history of pulmona...

OBJECTIVE We wanted to prospectively evaluate the interobserver agreement between radiology residents and expert radiologists for interpreting CT images for making the diagnosis of pulmonary embolism (PE). MATERIALS AND METHODS We assessed 112 consecutive patients, from April 2007 to August 2007, who were referred for combined CT pulmonary angiography and indirect CT venography for clinically...

The aim of this study was to evaluate whether right ventricle dilation at computed tomography (CT) angiography can be used to assess the risk of death in patients with acute pulmonary embolism. Medline and EMBASE were searched up to April 30, 2013. Studies reporting on the association between right ventricle dilation (right-to-left ventricle diameter) or dysfunction (inter-ventricular septal bo...

Pulmonary arteriovenous malformations are rare congenital abnormal connections between the pulmonary arteries and veins. The patients are usually asymptomatic [1]. Although their aetiology is unclear, it is presumed that genetic abnormalities constitute a predisposition [1, 2]. An arteriovenous malformation might cause serious complications if it remains undiagnosed and untreated [3]. We report...
