Mapping of brain imaging with PET/CT in Swedish university hospitals : Presentation of modality structure, examination method and reconstruction method with a comparison of radiation dose between PET and SPECT (English)
Abstract [en]

Positron emission tomography/computed tomography (PET/CT) is a method that quantitatively visualizes physiological processes. The most common indications for PET brain are early diagnosis of various dementia types with 18F-Fludeoxyglucose (18F-FDG). The hospital in Jonkoping installed a new PET/CT and brain examinations have not yet been performed. The aim of the study was to map how hospitals in Sweden performed seven selected brain examinations with PET/CT focusing on modality structure, examination method and reconstruction method, with a comparison of radiation dose between PET/CT and single photon emission computed tomography/CT (SPECT)/CT. Out of the nine university hospitals selected, two were excluded. The method was prospective with quantitative approach and data was collected through a protocol. Compilation was made on Excel and the statistics were processed using the Wilcoxon Signed Ranks Test. The result showed similarities, for example reconstruction method and differences, for example fasting time. Effective dose was higher on SPECT than PET in examination of Parkinson's disease, however no significant difference (p = 0,059) was detected. Higher effective doses on SPECT was due to longer half-lives and greater dosages of Ioflupane (123I-Datscan) than 18F-FDG. For further studies, more hospitals and parameters in the protocol can be included.
