13C PEG as an In Vivo Macromolecular Probe for MRI and Biophysical Studies of Detergent-Peptide and Detergent-Detergent Interactions using NMR
… as proteins and drug delivery systems, using 1H MRI. To overcome sensitivity challenges, a 28 kDa non-immunogenic tag is employed, consisting of 13C-enriched polyethylene glycol (PEG), whose spectroscopically equivalent 1H nuclei provide a signal amplification of 2500. Passing the 1H PEG …

Development and Optimisation of Radial Techniques for Sodium Magnetic Resonance Imaging
… was to provide techniques and hardware for 23Na MRI of the human brain, heart and muscle in a clinical scanner at 1.5T. For this purpose, radiofrequency (RF) coils were developed and a transmit/receive switch was adapted to 16.84 MHz. A 3D radial gradient echo (GRE) sequence was implemented, with …

Investigation of Trophon® 2 For High Level Disinfection of Rigid Endorectal Mri Coils
… increase in tumor aggressiveness. Traditional 1H MRI of the prostate is carried out using a disposable endorectal coil. Reusable intracavitary instruments, such as 1H and 13C/1H rigid endorectal coils, are classified as ‘semi-critical devices’ and must be processed by high-level disinfection …

MRI Quantification of Cortical Bone Microstructure and Material Composition with Ultrashort Echo Time Sequences
… mineral density. Recent advances in solid-state 1H and 31P MRI have demonstrated feasibility of ionizing-radiation-free quantification of cortical bone microstructure, organic matrix density, and mineral content in vivo in clinically practical acquisition times. Therefore, the primary objective …

Novel multi-parametric, multi-modality imaging for the assessment of tumour biology in renal cell carcinoma
… investigated morphological and physiological 1H-MRI to detect early response and predict outcome. Multiparametric MRI demonstrated physiological changes after 12 days of anti-vascular therapy, which were compatible with its mechanism of action. The reduction in tumour diffusivity correlated …

Anatomische und funktionelle Magnetresonanztomographie der menschlichen Lunge
… Im Vergleich zu konventionellen anatomischen 1H-MR-Verfahren wie IR- und MIR-Verfahren erhöht das MT-STIR-Verfahren das Signal-zu-Rausch-Verhältnis (SNR) des Lungenparenchyms signifikant und vermeidet den Signalausfall des Lungenparenchyms aufgrund der pathologischen Verkürzung der …
