Highly accurate coronary angiography with submillimetre, 16 slice computed tomography.
OBJECTIVE To assess submillimetre coronary computed tomographic angiography (CTA) in comparison with invasive quantitative coronary angiography as the gold standard and to examine the effect of significant coronary artery calcification (CAC), which is known to impede lumen visualisation, on the accuracy of the examination. METHODS After invasive coronary angiography, 58 patients underwent cor...
متن کاملEstimating risk of cancer associated with radiation exposure from 64-slice computed tomography coronary angiography.
CONTEXT Computed tomography coronary angiography (CTCA) has become a common diagnostic test, yet there are little data on its associated cancer risk. The recent Biological Effects of Ionizing Radiation (BEIR) VII Phase 2 report provides a framework for estimating lifetime attributable risk (LAR) of cancer incidence associated with radiation exposure from a CTCA study, using the most current dat...
متن کاملPatient-Specific Radiation Dose and Cancer Risk in Computed Tomography Examinations in Ondo, Nigeria
Introduction: The dose in computed tomography (CT) often approach or exceed the optimum levels, thereby increasing the probability of cancer induction. With wide application of this diagnostic test, it is expedient to determine the effective dose (ED) for each patient to estimate their cancer risk. This study was conducted to investigate the patient-specific dose (PSD) and cancer risk in CT exa...
متن کاملAssessment of radiation-induced cancer risk to patients undergoing computed tomography angiography scans
Background: Computed tomography angiography (CTA) scan is a suitable imaging technique to evaluate the blood vessels. However, one major disadvantage is the potential risk of cancer related to ionizing radiation exposure during the procedures. The aim of this investigation was to estimate the risk of exposure induced cancer death (REID) values for some common computed tomography angiography (CT...
متن کاملThe emerging use of 16- and 64-slice computed tomography coronary angiography in clinical cardiovascular practice.
Multi-slice computed tomography (MSCT) coronary angiography is an imaging modality that can identify patients with both soft and hard plaque, supplementing the information gleaned from an ordinary coronary calcium scan and classic risk-factor assessment. Clinicians now have the tools to identify the presence of coronary artery disease (CAD) in the presymptomatic phase, as well as those needed t...
