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 (...
Length and Geometric Patterns of the Greater Palatine Canal Observed in Cone Beam Computed Tomography
greater palatine canal
2014/11/6
The greater palatine canal is an important anatomical structure that is often utilized as a pathway for infiltration of local anesthesia to affect sensation and hemostasis. Increased awareness of the ...
Facial Soft-Tissue Asymmetry in 3D Cone Beam Computed Tomography Images of Children with Surgically Corrected Unilateral Clefts
soft-tissue depth facial reconstruction cleft lip with or without cleft palate
2014/11/6
Cleft lip with or without cleft palate (CL/P) is a relatively common craniofacial malformation involving bony and soft-tissue disruptions of the nasolabial and dentoalveolar regions. The combination o...
Evaluation of Radiation Exposure from Computed Tomography of the Head
reducing radiation levels automatic exposure control
2014/10/22
In an effort to reduce radiation exposure from computed tomography (CT), practitioners and facilities need to monitor radiation exposure while delivering high-quality diagnostic exams. Computed tomogr...
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

MicroCT All-ceramic crown Internal defect
2009/9/14
The purpose of this study was to examine all-ceramic crowns for internal defects using micro-focus X-ray computed tomography (microCT). Mono-ceramic CAD/CAM crowns, ceramic-core CAD/CAM crowns, and he...
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...
