Combined Positron-emission Tomography– Computed Tomography: Merging Form with Function
نویسندگان
چکیده
Combined positron-emission tomography–computed tomography is becoming a widely used imaging technique in nuclear medicine and nuclear radiology. Its unique dual functional-anatomical imaging capacity is highly complementary to conventional imaging, and it has become an integral part of the multidisciplinary clinical management of cancer in Hong Kong. The clinical value, efficacy, limitations, and cost-effectiveness of this technology are important pieces of information for referring physicians. This article briefly describes the basis of positron-emission tomography and combined positron-emission tomography–computed tomography, and reviews the current consensus on their clinical application in the diagnosis and treatment

Detection of Alzheimer\\\\\\\'s Disease using Multitracer Positron Emission Tomography Imaging
Alzheimer's disease is characterized by impaired glucose metabolism and demonstration of amyloid plaques. Individual positron emission tomography tracers may reveal specific signs of pathology that is not readily apparent on inspection of another one. Combination of multitracer positron emission tomography imaging yields promising results. In this paper, 57 Alzheimer's disease neuroimaging ini...

متن کاملA Comparative Study of the Construction of Positron Emission Tomography/Computed Tomography Facilities in Three South African Hospitals
Introduction: Development of higher energy modalities such as positron emission tomography/computed tomography (PET/CT), has led to more complex shielding problems. This is due to several factors, such as the radiopharmaceutical relatively high-administered activity, high patient throughput, and high energies of 511 kilo-electron volt (keV) positron annihilation photon...
