Performance evaluation of the whole-body PET scanner ECAT EXACT HR +
The results reveal that the ECAT EXACT HR/sup +/ has a good and nearly isotropic spatial resolution, however, it has a low slice sensitivity which is a limiting factor for image quality.
Quantitative diffusion tensor MR imaging of the brain: field strength related variance of apparent diffusion coefficient (ADC) and fractional anisotropy (FA) scalars
The objectives were to study the “impact” of the magnetic field strength on diffusion tensor imaging (DTI) metrics and also to determine whether magnetic-field-related differences in T2-relaxation
Use of scanner characteristics in iterative image reconstruction for high-resolution positron emission tomography studies of small animals
The presented data-handling strategy incorporates the image restoration step directly into the process of algebraic image reconstruction and obviates the need for ill-conditioned ”deconvolution“ procedures to be performed on the projections or on the reconstructed image.
In vivo 1H, 31P‐{1H} and 13C‐{1H} magnetic resonance spectroscopy of malignant histiocytoma and skeletal muscle tissue in man
The multinuclear in vivo MRS experiment may allow the non‐invasive observation of almost the complete pathway of phospholipid synthesis and degradation in intact human tissue.
Apoptosis and changes in glucose transport early after treatment of Morris hepatoma with gemcitabine
The increase in glucose uptake and TdR metabolism early after therapy is interpreted as a stress reaction of the tumour cells, protecting the cells from apoptosis during this early period after exposure to cytotoxic drugs like gemcitabine.
A novel method for real-time magnetic marker monitoring in the gastrointestinal tract.
The presented method has very moderate technical demands and allows us to monitor magnetic markers in real-time and offers the opportunity for remote drug release at any position of the gut.
Anisotropic Phantoms for Quantitative Diffusion Tensor Imaging and Fiber-Tracking Validation
Results may indicate that polyamide- and dyneema-based fiber phantoms provide the opportunity for verification and validation of DTI sequences on clinical scanner and can be applicable for testing the accuracy of fiber tracking algorithms.
