An 83-year-old woman presented to the emergency department with a 2-hour history of sudden chest pain and dyspnea. An initial ECG demonstrated nonspecific ST changes, and a portable chest x-ray suggested a widened mediastinum. A thoracic multidetector helical computed tomography (CT) angiogram was obtained to assess the possibility of aortic dissection (GE LightSpeed Plus, 2.5-mm collimation wi...

results the incidence of diagnosed thrombo-embolic complication was 32 of 1,153 admitted patients (2.8%; 95% confidence interval: 1.9 to 3.9) with a median interval of 14 days after anti-tb treatment initiation. the incidence of dvt and pte was 2% and 1%, respectively. thrombo-embolic events and dvt were more common in men than in women: 4.2% versus 1.3% (p = 0.003) and 3.5% versus 0.4%, respec...

INTRODUCTION Optimal arterial opacification is crucial in imaging the pulmonary arteries using computed tomography (CT). This poses the challenge of precisely timing data acquisition to coincide with the transit of the contrast bolus through the pulmonary vasculature. The aim of this quality assurance exercise was to investigate if a change in CT pulmonary angiography (CTPA) scanning protocol r...

This paper describe the case of pulmonary thromboembolism (PTE) in pregnancy diagnosed by angio CT The clinical diagnosis of PTE in normal population is difficult. In pregnancy is even more complicated, because physiologic changes of pregnancy can mimic signs and symptoms of PTE. Our patient presented dyspnoea, breathing effort and cyanosis of the mouth at admission. In the check-up there was a...

A 58-year-old man presented with persistent lung mass (Fig. 1). Pulmonary sequestration was diagnosed with multidetector CT angiography (MDCT) (Fig. 2). Advantages of MDCT over conventional angiography include its non-invasive nature, improved resolution and delineation of vasculature, 3D renderings, shorter acquisition time, and less exposure to radiation. Fig. 1. Computed tomography of the ch...

Todays, researchers in the field of Pulmonary Embolism (PE) analysis need to use a publicly available dataset to assess and compare their methods. Different systems have been designed for the detection of pulmonary embolism (PE), but none of them have used any public datasets. All papers have used their own private dataset. In order to fill this gap, we have collected 5160 slices of computed to...

Rasmussen's aneurysm is an inflammatory pseudo-aneurysmal dilatation of a branch of pulmonary artery adjacent to a tuberculous cavity. Life threatening massive hemoptysis from the rupture of a Rasmussen's aneurysm is an uncommon yet life threatening complication of cavitary tuberculosis (TB). We present a case of a young woman who presented with low-grade fever and hemoptysis. Computed tomograp...

Single coronary anomalies are one of the rarest variants of coronary anatomy. Widespread use of coronary CT angiography has made it possible to diagnose these variants with increasing incidence. We report two cases of single right coronary trunk with different anatomic course of the left coronary artery; one anterior to the main pulmonary artery and the second between the main pulmonary artery ...
