Quantitative Amyloid Imaging Using Image-Derived Arterial Input Function
Amyloid PET imaging is an indispensable tool widely used in the investigation, diagnosis and monitoring of Alzheimer's disease (AD). Currently, a reference region based approach is used as the mainstream quantification technique for amyloid imaging. This approach assumes the reference region is amyloid free and has the same tracer influx and washout kinetics as the regions of interest. However,...
متن کاملQuantification of brain glucose metabolism by 18F-FDG PET with real-time arterial and image-derived input function in mice.
UNLABELLED Kinetic modeling of PET data derived from mouse models remains hampered by the technical inaccessibility of an accurate input function (IF). In this work, we tested the feasibility of IF measurement with an arteriovenous shunt and a coincidence counter in mice and compared the method with an image-derived IF (IDIF) obtained by ensemble-learning independent component analysis of the h...
متن کاملFully automated calculation of image-derived input function in simultaneous PET/MRI in a sheep model
BACKGROUND Obtaining the arterial input function (AIF) from image data in dynamic positron emission tomography (PET) examinations is a non-invasive alternative to arterial blood sampling. In simultaneous PET/magnetic resonance imaging (PET/MRI), high-resolution MRI angiographies can be used to define major arteries for correction of partial-volume effects (PVE) and point spread function (PSF) r...
متن کاملFDG-PET Quantification of Lung Inflammation with Image-Derived Blood Input Function in Mice
Dynamic FDG-PET imaging was used to study inflammation in lungs of mice following administration of a virulent strain of Klebsiella (K.) pneumoniae. Net whole-lung FDG influx constant (K(i)) was determined in a compartment model using an image-derived blood input function. Methods. K. pneumoniae (~3 x 10(5) CFU) was intratracheally administered to six mice with 6 other mice serving as controls....
متن کاملImage derived input function applied in CBF Studies with [15O]water PET in an integrated MR-PET
Institute of Neuroscience and Medicine, Forschungszentrum Jülich, Jülich, Germany To quantify CBF studies using [O]water PET an input function must be provided, e.g. by means of arterial blood sampling. An image derived input function (IDIF) gained from the dynamic PET images may be a non-invasive alternative. The time-activity curve (TAC) of the blood can be obtained from a volume of interest ...
