13. Avaliação da aterosclerose coronária em pacientes com doença de Chagas por tomografia computadorizada de múltiplos detectores / Evaluation of coronary atherosclerosis in patients with Chagas disease by multidetector computed tomography
INTRODUÇÃO: A doença de Chagas (DCh) representa um grave problema de saúde pública na maioria dos países da América Latina. Sintomatologia frequente, a dor torácica ou precordial em pacientes com DCh pode assemelhar-se àquela observada na doença arterial coronária (DAC), constituindo-se, dessa forma, em desafio diagnóstico para os clínicos. A fr

14. The accuracy of multidetector Computed Tomography for preoperative staging of renal cell carcinoma
PURPOSE: The purpose of this study was to evaluate the accuracy of multidetector computed tomography (MDCT) in the preoperative staging of renal cell carcinoma (RCC). MATERIALS AND METHODS: We retrospectively reviewed the clinical and pathological records of 312 patients with RCC who underwent staging MDCT before surgery. Radiographic findings were compared

15. Predicting dysthyroid optic neuropathy using computed tomography volumetric analyses of orbital structures
OBJECTIVE: To evaluate the ability of orbital apex crowding volume measurements calculated with multidetector-computed tomography to detect dysthyroid optic neuropathy. METHODS: Ninety-three patients with Graves' orbitopathy were studied prospectively. All of the patients underwent a complete neuro-ophthalmic examination and computed tomography scanning. Vol

16. The diameter of the originating vein determines esophageal and gastric fundic varices in portal hypertension secondary to posthepatitic cirrhosis
OBJECTIVE: The aim of this study was to determine whether and how the diameter of the vein that gives rise to the inflowing vein of the esophageal and gastric fundic varices secondary to posthepatitic cirrhosis, as measured with multidetector-row computed tomography, could predict the varices and their patterns. METHODS: A total of 106 patients with posthepa

17. Avaliação da fibrose miocárdica pela ressonância magnética e tomografia computadorizada com múltiplos detectores na cardiomiopatia hipertrófica / Myocardial fibrosis evaluation by magnetic resonance and multidetector computed tomography in hypertrophic cardiomyopathy
Hypertrophic cardiomyopathy (HCM) is a genetic cardiac disorder leading cause of sudden death in young people with extremely variable presentation, from asymptomatic to sudden death as first symptom, leads to challenging risk stratification. Recently, both cardiovascular magnetic resonance (CMR) and multidetector computed tomography (MDCT) were able to asses

18. A multidetector tomography protocol for follow-up of endovascular aortic aneurysm repair
OBJECTIVE: The purpose of this study was to improve the use of 64-channel multidetector computed tomography using lower doses of ionizing radiation during follow-up procedures in a series of patients with endovascular aortic aneurysm repair. METHODS: Thirty patients receiving 5 to 29 months of follow-up after endovascular aortic aneurysm repair were analyzed

19. Earthquake-related pelvic crush fracture vs. non-earthquake fracture on digital radiography and MDCT: a comparative study
OBJECTIVE: To determine the features of earthquake-related pelvic crush fractures versus non-earthquake fractures with digital radiography and multidetector row computed tomography. METHODS: One hundred and sixty-seven survivors with pelvic crush fractures in the 2008 Sichuan earthquake were entered in our study as the earthquake-related group (139 underwent

20. Comparative study of earthquake-related and non-earthquake-related head traumas using multidetector computed tomography
OBJECTIVE: The features of earthquake-related head injuries may be different from those of injuries obtained in daily life because of differences in circumstances. We aim to compare the features of head traumas caused by the Sichuan earthquake with those of other common head traumas using multidetector computed tomography. METHODS: In total, 221 patients wit

21. Thoracic Injuries in earthquake-related versus non-earthquake-related trauma patients: differentiation via Multi-detector Computed Tomography
PURPOSE: Massive earthquakes are harmful to humankind. This study of a historical cohort aimed to investigate the difference between earthquake-related crush thoracic traumas and thoracic traumas unrelated to earthquakes using a multi-detector Computed Tomography (CT). METHODS: We retrospectively compared an earthquake-exposed cohort of 215 thoracic trauma c

22. Coronary artery calcification is associated with insulin resistance index in patients with type 1 diabetes
The objective of the present study was to evaluate the risk factors associated with the presence of coronary artery calcification (CAC) in patients with type 1 diabetes (T1D). A cross-sectional study was conducted on 100 consecutive T1D patients without coronary artery disease, with at least 5 years of diabetes and absence of end-stage renal disease. Mean ag

24. Tecnologias para investigação da DAC: relação entre publicações científicas e utilização clínica
FUNDAMENTO: Apesar de algumas evidências sugerirem associação entre a exposição de uma tecnologia na literatura científica e sua difusão na prática clínica, poucos estudos avaliaram essa associação. OBJETIVO: O objetivo deste estudo é analisar se o padrão de publicação científica sobre duas tecnologias competitivas utilizadas na avaliação d
