Validation of cone-beam computed tomography and magnetic resonance imaging of the porcine spine: a comparative study with multidetector computed tomography and anatomical specimens
(Elsevier B.V., 2015-05-01)
BACKGROUND CONTEXT: New spinal interventions or implants have been tested on ex vivo or in vivo porcine spines, as they are readily available and have been accepted as a comparable model to human cadaver spines. Imaging-guided ...
Diagnostic ability of barrett's index to detect dysthyroid optic neuropathy using multidetector computed tomography
(Faculdade de Medicina / USP, 2008)
OBJECTIVES: The objective of this study was to evaluate the ability of a muscular index (Barrett's Index), calculated with multidetector computed tomography, to detect dysthyroid optic neuropathy in patients with Graves' ...
Tranverse colon volvulus
The volvulus of the colon is a relatively common cause of colonic obstruction, mainly in the sigmoid colon, less frequent in the caecum, and rarely in the transverse colon. Multidetector tomography (MDCT) is able to establish ...
Acute and chronic mesenteric ischemia: MDCT findings
(Sociedade Brasileira de Angiologia e de Cirurgia Vascular (SBACV), 2010)
Mesenteric ischemia is caused by a reduction in mesenteric blood flow. It can be divided into acute and chronic, based upon the rapidity and the degree to which the blood flow is compromised. The authors retrospectively ...
Preaortic Iliac Confluence (Marsupial Vena Cava): Report of 4 Cases
(LIPPINCOTT WILLIAMS & WILKINS, 2008)
Congenital anomalies of the inferior vena cava (IVC) call represent a difficult for abdominal surgeries, and the radiologist must be aware even of the less common of these anatomical variations. Preaortic iliac venous ...
Diagnosis of hepatic steatosis by contrast-enhanced abdominal computed tomography
(Colégio Brasileiro de Radiologia e Diagnóstico por Imagem, 2013-06-01)
Objective To evaluate the diagnostic capacity of abdominal computed tomography in the assessment of hepatic steatosis using the portal phase with a simplified calculation method as compared with the non-contrast-enhanced ...
