Performance evaluation of the whole-body PET scanner ECAT EXACT HR +
- L. Adam, J. Zaers, W. J. Lorenz
- Physics, Medicine
- 1 June 1997
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

- 1 July 1997
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.

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.
A novel method for real-time magnetic marker monitoring in the gastrointestinal tract
- W. Andrä, H. Danan, M. Bellemann
- MedicinePhysics in Medicine and Biology
- 1 October 2000
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.
Apoptosis and changes in glucose transport early after treatment of Morris hepatoma with gemcitabine
- U. Haberkorn, M. Bellemann, R. Kinscherf
- Medicine, BiologyEuropean Journal of Nuclear Medicine
- 1 April 2001
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.
