Multislice Spiral Computed Tomography in Cardiac Imaging
Objective: Multislice computed tomography is an emerging technology with the potential for non-invasive coronary investigation. The aim of this study was to evaluate the feasibility and limitations of multislice computed tomography in the detection of coronary artery disease. Patients and Methods: Multislice computed tomography was performed in symptomatic patients with atypical chest pain and ...
متن کاملMultislice spiral computed tomography of subacute myocardial infarction.
A62-year-old man presented to our emergency room with severe retrosternal pain. An ECG showed an acute lateral myocardial infarction, and the patient was referred for cardiac catheterization. One and a half hours after the onset of acute chest pain, coronary angiography revealed a thrombotic occlusion of the intermedial branch of the left coronary artery. Mechanical recanalization of the infarc...
متن کاملRadiation exposure in cardiac multislice spiral computed tomography (MSCT)
Computed tomographic (CT) imaging involves exposure to ionizing radiation, with a consequent potential risk to the patient. Here we review the technical factors that affect the radiation dose in cardiac CT diagnostic procedures, the parameters that are used to measure and compare radiation doses, the magnitude of radiation exposure, and how to efficiently reduce it.
متن کاملNoninvasive coronary artery imaging by multislice spiral computed tomography.
Although the excellent spatial resolution of multislice spiral computed tomography (MSCT) enables the coronary arteries to be visualized, its limited temporal resolution results in poor image reproducibility because of cardiac motion artifact (CMA) and hence limits its widespread clinical use. A novel retrospectively ECG-gated reconstruction method has been developed to minimize CMA. In 88 cons...
متن کاملComparison of Spiral Computed Tomography and Cone-Beam Computed Tomography
Imaging is a highly dependent technology in the clinical assessment of a patient. With respect to the dental field, imaging has travelled a long way from the conventional radiographs to modern techniques like the computed tomography (CT) and the cone-beam computed tomography (CBCT). This article describes the evolution made in the CT in the field of dental imaging and attempts to compare the CT...
