Principles of CT: multislice CT.
This article describes the principles and evolution of multislice CT (MSCT), including conceptual differences associated with slice definition, cone beam effects, helical pitch, and helical scan technique. MSCT radiation dosimetry is described, and dose issues associated with MSCT-and with CT in general-as well as techniques for reducing patient radiation dose are discussed. Factors associated ...
متن کاملMultislice CT in tumor detection
This seminar will address the dramatic impact of multislice (multidetector) CT upon imaging the oncologic patient. This technology is responsible for a dramatic change in the speed and ability for diagnostic radiologists to detect disease. Technology has advanced rapidly in the last 20 years from single-slice CT scanners to helical (spiral) technology. Continuous acquisitions of multiple images...
متن کاملDiagnosing brain death by CT perfusion and multislice CT angiography.
INTRODUCTION Although the diagnosis of brain death (BD) is usually based on clinical criteria, in sedated patients, ancillary techniques are needed. This study was designed to assess the accuracy of cerebral multislice computed tomographic angiography (CTA) and CT perfusion (CTP) in diagnosing BD. METHODS Prospective observational study in 27 BD patients. RESULTS All patients were diagnosed...
متن کاملMultislice CT angiography of the plantar arch
The aim of this case report is to present a multislice computed tomography angiography (CTA) procedure for viewing the plantar arch. A CTA was requested to determine the vascular sufficiency of the plantar arch of a 64-year-old patient with necrotic and gangrenous toes. The patient had recently undergone a proximal wedge osteotomy procedure for correction of a hallux valgus deformity. A 16-dete...
متن کاملPrinciples of CT and CT technology.
This article provides a review of the basic principles of CT within the context of the evolution of CT. Modern CT technology can be understood as a natural progression of improvements and innovations in response to both engineering problems and clinical requirements. Detailed discussions of multislice CT, CT image quality evaluation, and radiation doses in CT will be presented in upcoming artic...
