Low-dose CT coronary angiography in the step-and-shoot mode: diagnostic performance.
OBJECTIVE To investigate the performance of low-dose, dual-source computed tomography (DSCT) coronary angiography in the step-and-shoot (SAS) mode for the diagnosis of significant coronary artery stenoses in comparison with conventional coronary angiography (CCA). DESIGN, SETTING AND PATIENTS Prospective, single-centre study conducted in a referral centre enrolling 120 patients (71 men, mean ...
متن کاملLow radiation dose imaging of myocardial perfusion and coronary angiography with a hybrid PET/CT scanner
OBJECTIVES To test the image quality and feasibility of a sequential low radiation dose protocol for hybrid cardiac PET/CT angiography (CTA). BACKGROUND Multidetector computed tomography (MDCT) is a non-invasive method for coronary angiography. The negative predictive value of MDCT is high but perfusion imaging has a role in detecting functional significance of coronary lesions. This has enco...
متن کاملLow-dose dual-source CT angiography with iterative reconstruction for coronary artery stent evaluation.
OBJECTIVES The purpose of this study was to evaluate the image quality and diagnostic accuracy of very low-dose, dual-source computed tomography (DSCT) angiography for the evaluation of coronary stents. BACKGROUND Iterative reconstruction (IR) leads to substantial reduction of image noise and hence permits the use of very low-dose data acquisition protocols in coronary computed tomography ang...
متن کاملDual-source CT in step-and-shoot mode: noninvasive coronary angiography with low radiation dose.
PURPOSE To prospectively investigate computed tomographic (CT) image quality parameters by using different protocols and to calculate radiation dose estimates for noninvasive coronary angiography performed with dual-source CT in the step-and-shoot (SAS) mode. MATERIALS AND METHODS This study was local ethics board approved; written informed consent was obtained from all patients. In the preli...
متن کاملUsefulness of additional coronary calcium scoring in low-dose CT coronary angiography with prospective ECG-triggering impact on total effective radiation dose and diagnostic accuracy.
RATIONALE AND OBJECTIVES To determine the impact of additional coronary calcium scoring on total effective radiation dose and diagnostic accuracy of low-dose computed tomography coronary angiography (CTCA) with prospective electrocardiogram (ECG) triggering. MATERIALS AND METHODS Sixty-one consecutive patients underwent 64-slice CTCA using prospective ECG triggering, calcium scoring, and inva...
