Engineering of inorganic nanoparticles as magnetic resonance imaging contrast agents.

Chemical Society reviews

Ni D, Bu W, Ehlerding EB, Cai W, Shi J.
PMID: 29071327
Chem Soc Rev. 2017 Nov 27;46(23):7438-7468. doi: 10.1039/c7cs00316a.

Magnetic resonance imaging (MRI) is a highly valuable non-invasive imaging tool owing to its exquisite soft tissue contrast, high spatial resolution, lack of ionizing radiation, and wide clinical applicability. Contrast agents (CAs) can be used to further enhance the...

Adverse reactions to contrast media.

Professional nurse (London, England)

Howatson-Jones IL.
PMID: 12026424
Prof Nurse. 2000 Sep;15(12):771-4.

Knowledge of the physiological effects of contrast media helps radiology nurses to prepare patients fully. Hypersensitive reactions can progress rapidly so immediate nursing interventions and medical assistance are required. Pre-assessment, psychological support, vigilance, integrated monitoring and decision-making are the...

A smart magnetic resonance contrast agent for selective copper sensing.

Journal of the American Chemical Society

Que EL, Chang CJ.
PMID: 17165700
J Am Chem Soc. 2006 Dec 20;128(50):15942-3. doi: 10.1021/ja065264l.

We describe the synthesis and properties of Copper-Gad-1 (CG1), a new type of smart magnetic resonance (MR) sensor for selective detection of copper. CG1 is composed of a gadolinium contrast agent core tethered to copper-selective recognition motif. Cu2+-induced modulation...

Microfabricated multispectral MRI agents: a brief overview.

Annual International Conference of the IEEE Engineering in Medicine and Biology Society. IEEE Engineering in Medicine and Biology Society. Annual International Conference

Zabow G.
PMID: 19964367
Annu Int Conf IEEE Eng Med Biol Soc. 2009;2009:4479-82. doi: 10.1109/IEMBS.2009.5333677.

This paper provides an introductory overview of recent microfabricated, as opposed to traditional chemically synthesized, magnetic resonance imaging (MRI) contrast agents. As a specific example of the enhanced agent functionality that top-down micro-engineering allows, the paper focuses on recently...

Cellular and Molecular Imaging Using Chemical Exchange Saturation Transfer.

Topics in magnetic resonance imaging : TMRI

McMahon MT, Gilad AA.
PMID: 27748713
Top Magn Reson Imaging. 2016 Oct;25(5):197-204. doi: 10.1097/RMR.0000000000000105.

Chemical exchange saturation transfer (CEST) is a powerful new tool well suited for molecular imaging. This technology enables the detection of low concentration probes through selective labeling of rapidly exchanging protons or other spins on the probes. In this...

Cancer treatment has a far greater chance of success if the neoplasm is diagnosed before the onset of metastasis to vital organs. Hence, cancer early diagnosis is extremely important and remains a major challenge in modern therapeutics. In this...

Improvement in the contrast of CEST MRI via intermolecular double quantum coherences.

Physics in medicine and biology

Zhang S, Zhu X, Chen Z, Cai C, Lin T, Zhong J.
