contrast-induced nephropathy outpatient CECT
2014/11/28
Background and objectives: No prospective study has reported the incidence of contrast-induced nephropathy (CIN) or the associated morbidity and mortality after contrast-enhanced computed tomography (...
Evaluation of Coronary Venous Anatomy by Multislice Computed Tomography
Cardiac Resynchronization Coronary Vein MultiDetector Computed Tomography
2013/2/20
Background:The coronary venous system is increasingly targeted for pacing in patients with severe heart failure. The recent advancement of Multi-Detector Computed Tomography (MDCT) allows accurate ana...
Ditection of coronary artery disease:accuracy of 64-slice computed tomography versus converntional invasive angiography
Coronary artery disease (CAD) multislice computed tomography (MSCT) MSCT diagnostic accuracy 64-slice MSCT
2009/12/16
Background: Multislice computed tomography (MSCT) is a noninvasive method of detecting coronary artery disease (CAD). The purpose of the present study was to investigate the accuracy of 64-slice MSCT ...
Radiological Approach to Asthma and COPD-The Role of Computed Tomography
airway remodeling asthma chronic obstructive pulmonary disease (COPD) computed tomography (CT) parenchymal lung disease
2010/11/16
Asthma and chronic obstructive pulmonary disease (COPD) are among the most prevalent lung diseases. In both asthma and COPD, airway inflammation leads to airway remodeling. Parenchyma of the lung is a...
Cardiac computed tomography (CT) has been a hot topic for years because of the clinical importance of cardiac diseases and the rapid evolution of CT systems. In this paper, we propose a novel strategy...
Comparison of Quadratic- and Median-Based Roughness Penalties for Penalized-Likelihood Sinogram Restoration in Computed Tomography
Penalized-Likelihood Sinogram Restoration Computed Tomography
2009/9/8
We have compared the performance of two different penalty choices for a penalized-likelihood sinogram-restoration strategy we have been developing. One is a quadratic penalty we have employed previous...
