Acute aortic syndrome can be due to acute aortic dissection, intramural hematoma, penetrating atherosclerotic ulcer, or unstable thoracic aneurysm. These life-threatening conditions are clinically indistinguishable, often presenting with acute chest pain. Contrast-enhanced, cardiac-gated multidetector computed tomography (CT) is a highly accurate imaging method for determining the cause of acut...

Fig. 1. Transthoracic Doppler echocardiography revealing severe obstruction of themechanical valve (A). The cause of obstruction could not be visualised by trans-oesophageal echocardiography (B). Multiplanar reformatted images on contrast-enhanced 64-slice multidetector CT clearly depict a circular mass (arrows) with high HU values involving both atrial (C) and ventricular (D) sides of mechanic...

Computed Tomography (CT) examinations have rapidly increased in number over the last few years due to recent advances such as the spiral, multidetector-row, CT fluoroscopy and Positron Emission Tomography (PET)-CT technology. This has resulted in a large increase in collective radiation dose as reported by many international organisations. It is also stated that frequently, image quality in CT ...

Cystic adenomatoid malformation is a rare pulmonary hamartomatous lesion, of an unknown etiology. Report a singular case of CAM of one newborn, with marked respiratory distress. Using different method (chest X-ray, Multidetector row CT associated at multiplanar and three-dimensional reconstructions), we obtained an accurate diagnosis of site and nature, critical for a correct therapeutic approach.

SARS-CoV-2 is a virus of the coronavidae family that causes COVID-19, disease emerged in 2019 and has already gone around world, causing World Health Organization to decree pandemic state 2020. One consequences COVID-19 development Pulmonary Thromboembolism (PE), which one or more pulmonary arteries are blocked by blood clot. In this association with PE caused pro-inflammatory hypercoagulant de...

We report here on an uncommon case of peliosis hepatis with hemorrhagic necrosis that was complicated by massive intrahepatic bleeding and rupture, and treated by emergent right lobectomy. We demonstrate the imaging findings, with emphasis on the triphasic, contrast-enhanced multidetector CT findings, as well as reporting the clinical outcome in a case of peliosis hepatis with fatal hemorrhage.

BACKGROUND The objective of this study was to retrospectively investigate and compare multidetector computed tomography findings of hepatocellular carcinoma (HCC) in hepatitis B virus (HBV)-positive and -negative patients. METHODS Triphasic (arterial, portal venous, and delayed phases) dynamic multidetector computed tomography (CT) was performed in 83 patients with HCC, 48 of whom were HBV-po...

PURPOSE To prospectively evaluate the effect of single- versus two-segment image reconstruction on image quality and diagnostic accuracy at 64-section multidetector computed tomographic (CT) coronary angiography by using conventional coronary angiography as the reference standard. MATERIALS AND METHODS The study design was approved by a human research committee; patients gave informed consent...
