Noninvasive 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 کاملHigh-resolution spiral computed tomography coronary angiography in patients referred for diagnostic conventional coronary angiography.
BACKGROUND The diagnostic performance of the latest 64-slice CT scanner, with increased temporal (165 ms) and spatial (0.4 mm3) resolution, to detect significant stenoses in the clinically relevant coronary tree is unknown. METHODS AND RESULTS We studied 52 patients (34 men; mean age, 59.6+/-12.1 years) with atypical chest pain, stable or unstable angina pectoris, or non-ST-segment elevation ...
متن کاملSpiral computed tomography for pulmonary embolism.
Spiral computed tomography pulmonary angiography is increasingly used in the non-invasive investigation of patients with suspected pulmonary embolism. This review will focus on current techniques and indications with an explanation of the computed tomography signs of pulmonary embolism, possible pitfalls in interpretation and limitations of the technique.
متن کاملSpiral computed tomography for acute pulmonary embolism.
There is still considerable debate about the optimal diagnostic imaging modality for acute pulmonary embolism. If imaging is deemed necessary from an initial clinical evaluation such as d-dimer testing, options include nuclear medicine scanning, catheter pulmonary angiography, and spiral CT. In many institutions, spiral CT is becoming established as the first-line imaging test in daily clinical...
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...
