T2*‐dependent contrast preparationA method for encoding T2*-dependent contrasts into the preparation period of magnetization-prepared uitrafast MRI sequences is demonstrated and validated. The preparation block consists of a 90° - T - 90°p sequence, where p is shifted by 90° for successive ...
Multiparametric MRI of the prostate is now recommended as the initial diagnostic test for men presenting with suspected prostate cancer, with a negative MRI enabling safe avoidance of biopsy and a positive result enabling MRI-directed sampling of lesions. The diagnostic pathway consists of several step...

The application of zeolite molecular sieves as magnetic resonance imaging contrast agents for the gastrointestinal tract is described. Results for the preparation and characterization of zeolite GdNaY, the principle component of Gadolite, are presented. Ion exchange studies suggest GdNaY is stable to re...
One important task is the preparation of a brain atlas database that provide comprehensive information containing multidimensional data with various image contrasts, which can be achievable using a magnetic resonance imaging (MRI). Advanced MRI techniques such as diffusion tensor imaging (DTI), which ...
Water-soluble fluorinated polymer nanoparticles (PNPs) with well-defined structure were successfully prepared as a F-19 MRI contrast agent by living radical copolymerization of 2,2,3,3-tetrafluoropropyl methacrylate (TFPMA) and tert-buty... M Ogawa,H Kataoka,S Nitahara,... - 《Bulletin of ...
A phenomenon known as magnetization transfer (MT) is thought to provide the primary source of contrast in NM-MRI, due to the increased contrast found with MT preparation of NM-MRI pulse sequences. MT contrast results from the interaction and exchange between water protons and the protons ...
A nanoparticle magnetic resonance imaging (MRI) contrast agent targeted to liver was developed by conjugation of gadolinium (Gd) chelate groups onto the biocompatible poly(l-lactide)-block-poly (ethylene glycol) (PLA-PEG) nanoparticles. PLA-PEG conjugated with diethylenetriaminopentaacetic acid (DTPA)...
Fe concentrations. The 18 nm Zn0.3Fe2.7O4@SiO2nanoparticles show a very high r1 = 615 s−1mM−1, with only a modest increase in the r2/r1 = 2.7. In contrast, commercial high-field Gd-based T1agents have r1 = 3 to 7 s−1mM−1, with r2/r1~ 1.2 to ...
