Abstract Pulmonary embolism (PE) is a condition due to blood clots obstructing pulmonary arteries, often related deep venous thrombosis (DVT). PE can be responsible for acute and even life-threatening clinical situations it may also lead chronic sequelae such as thromboembolic hypertension (CTEPH). Signs symptoms associated overlap those of many other diseases (e.g. chest pain, dyspnea, etc.), ...

Recent developments in computed tomography technology have made imaging of the coronary arteries possible. All the same, the rapid motion and small dimensions of the coronary vessels make coronary computed tomography angiography (coronary CTA) challenging. With the last generations of 16- and 64-slice computed tomography and adequate patient preparation (which includes lowering of the heart rat...

Coronary computed tomographic angiography (cCTA) as a noninvasive approach underlies a rapid technological development with an impressive improvement of spatial and temporal resolution of the images. Therefore, it has become an accurate and costeffective method to detect or exclude obstructive coronary artery disease (CAD) in patients with low to medium cardiovascular risk profile, as recommend...

To evaluate the evidence for the use of spiral volumetric computed tomography (SVCT) in the diagnosis of acute pulmonary embolism (PE), the 11 English-language studies published through July 1998 that compared SVCT with a reference standard for PE were systematically reviewed. Among the reviewed studies, methodological problems were common. Only 5 of these studies fulfilled 5 of 11 basic standa...

PURPOSE In this study, the pulmonary arterial computed tomography obstruction index ratio, which indicates the degree and extent of thrombotic arterial occlusion, was calculated in cases with pulmonary thromboembolism. Our objectives were to investigate the value of this index for the identification of cases with massive pulmonary thromboembolism and to search for correlations between this inde...

Abstract We report a case of 34-year-old woman who presented with chest pain, shortness breath, and dry cough 1 month duration. Contrast-enhanced computed tomography the revealed an enlarged tortuous right pulmonary vein that could not conclusively exclude arteriovenous malformation. Further evaluation digital subtraction angiography excluded malformation confirmed presence varix. Accordingly, ...

A 55-year-old man was re-admitted for persistent hemoptysis and high fever three weeks after an initial left upper sleeve lobectomy for a central squamous lung cancer tumor. Pulmonary artery pseudoaneurysm and pulmonary infection were confirmed by multidetector computed tomography angiography and subsequent emergency completion pneumonectomy. The development of pulmonary artery pseudoaneurysm, ...

A nomalous origin of the right coronary artery (RCA) arising from the pulmonary trunk (PT) is rare, with an expected incidence of 0.002%. Numerous modalities are available to aid in establishing the diagnosis, including echocardiography, digital subtraction angiography, magnetic resonance angiography, and computed tomography coronary angiography (CTCA). We describe a case of anomalous origin of...
