PET and PET/CT: Basic Principles and Instrumentation

Abstract: The increasing role of positron emission tomography (PET) in the diagnosis and staging of malignant disease and monitoring of therapy response can be attributed to significant improvements made in the performance of this imaging technology Anticipated progress is frequently constrained by the physics of PET, and current designs of PET scanners aim at an ultimately high spatial resolution and sensitivity as well as improved signal-to-noise properties Recent advances in the field of PET instrumentation include the introduction of novel scintillation crystal technology and detector electronics, as well as the widespread introduction of fast and efficient, iterative image reconstruction algorithms for fully three-dimensional (3D) PET data sets These advances have led to a dramatic reduction in clinical imaging times while improving image quality Finally, the combination of functional imaging and computed tomography (CT) within a combined PET/CT tomograph provides a tool to accurately localise functional abnormalities in an anatomical context

Advanced imaging technology in surgical innovation.

Abstract: Advanced imaging technologies including computed tomography (CT) and magnetic resonance imaging (MRI) have immensely expanded possibilities in imaging and surgery. The accurate visualization of bones and soft tissue has transformed the surgical management of numerous diseases, including middle ear disease, orthopedic and reconstructive cases, and cancer. In fact, in surgical subspecialties such as neurosurgery, CT and MRI are the diagnostic modalities of choice for preoperative evaluation of patients. Furthermore, the ongoing development of the newer imaging technologies continues to expand image-guided surgical treatments. The development of new radiological modalities combined with the modern training of surgeons will provide an exciting landscape for future practicing physicians.

Technical challenges for the construction of a medical image database

Abstract: Infrared thermal imaging was first made available to medicine in the early 1960's. Despite a large number of research publications on the clinical application of the technique, the images have been largely qualitative. This is in part due to the imaging technology itself, and the problem of data exchange between different medical users, with different hardware. An Anglo Polish collaborative study was set up in 2001 to identify and resolve the sources of error and problems in medical thermal imaging. Standardisation of the patient preparation, imaging hardware, image capture and analysis has been studied and developed by the group. A network of specialist centres in Europe is planned to work to establish the first digital reference atlas of quantifiable images of the normal healthy human body. Further processing techniques can then be used to classify abnormalities found in disease states. The follow up of drug treatment has been successfully monitored in clinical trials with quantitative thermal imaging. The collection of normal reference images is in progress. This paper specifies the areas found to be the source of unwanted variables, and the protocols to overcome them.
