background the present data show a global increase in the rate of cardiovascular disease. cardiac ct angiography has developed as a fast and non-invasive cardiac imaging modality following the introduction of multi-slice computed tomogaraphy. conclusions the total mean radiation dose to the thyroid and gonads was 0.36 msv, and 96.5 μsv, respectively for the subjects. these values were high for ...
Abstract Funding Acknowledgements Type of funding sources: None. Background Coronary artery disease is a major public health problem. Early diagnosis and treatment coronary crucial. There need for practical, reliable cost-effective non-invasive imaging tool. We aimed to evaluate the rest ischemia with speckle tracking echocardiography (STE) compare two methods in patients who were scheduled ang...
The saga of CT coronary angiography continues and new exciting developments are on the horizon. We have witnessed the astounding rapid developments in CT technology from 4-, 16-, 64-, 128-, 256-, to 320-slice acquisition, with tube rotational speed increasing from 250 to 87 ms and with ever decreasing radiation exposure from 20 to ,1 mSv with the preservation of image quality. One would think t...
Anomalous left coronary artery from pulmonary (ALCAPA) is a rare congenital anomaly with high rate of mortality in first year life. It one the most common causes cardiomyopathy and myocardial ischemia children. In present scenario, computed tomography (CT) angiography sufficient for diagnosis ALCAPA, eliminating need invasive angiography. CT performed infants suspicion ALCAPA technically challe...
BACKGROUND AND OBJECTIVES Plaque composition rather than degree of luminal narrowing may be predictive of future coronary events in high risk patients. The purpose of this study was to compare degree of plaque burden and composition with multislice computed tomography (MSCT) angiography between diabetic and non-diabetic patients. SUBJECTS AND METHODS A total of 452 consecutive MSCT angiograph...
Coronary CT angiography has been increasingly used in the diagnosis of coronary artery disease owing to rapid technological developments, which are reflected in the improved spatial and temporal resolution of the images. High diagnostic accuracy has been achieved with multislice CT scanners (64 slice and higher), and in selected patients coronary CT angiography is regarded as a reliable alterna...
