Sir, To correlate magnetic resonance imaging (MRI) patterns with tissue destruction is interesting, but to correlate MR patterns with ongoing inflammation to predict the fate of a lesion is of great importance in clinical practice of Multiple sclerosis (MS). The paper of Nessler et al. (2007) reporting early and predictive MRI changes in a mouse model of MS is therefore of great interest. The p...
Abstract The understanding of the engrafted cell behaviors such as survival, growth and distribution is prerequisite to optimize therapy, a multimodal imaging at both anatomical molecular levels designed achieve this goal. We constructed lentiviral vector carrying genes ferritin heavy chain 1 ( FTH1 ), near-infrared fluorescent protein iRFP ) enhanced green egfp established induced pluripotent ...
Previously rodent preclinical research in gliomas frequently involved implantation of cell lines such as C6 and 9L into the rat brain. More recently, mouse models have taken over, the genetic manipulability of the mouse allowing the creation of genetically accurate models outweighed the disadvantage of its smaller brain size that limited time allowed for tumor progression. Here we illustrate a ...
Lung parenchyma remains one of the most difficult tissues to be imaged by means of magnetic resonance imaging (MRI). Several MRI techniques are routinely used for lung imaging. However, manganese-enhancement MRI (MEMRI) technique has not been associated with pulmonary MRI. Here, we evaluated T(1) -enhancement in the rat lung after a manganese instillation, using a 4.7 T magnet with a radial ult...
Introduction. The development of transceiver volume coils for high field MRI is still a very dynamic field of investigation and development. A volume coil based on the high frequency cavity resonator [1] is presented in this paper for whole-body MRI of rodents at 7 Tesla (proton frequency: 299.47 MHz). This coil design has been previously tested on phantoms at 170 MHz (4T for protons) with stan...
