Cryogenic Preamplifiers for Magnetic Resonance Imaging.
Johansen DH, et al. IEEE Trans Biomed Circuits Syst 2018. PMID 29377808
Pursuing the ultimate limit of detection in magnetic resonance imaging (MRI) requires cryogenics to decrease the thermal noise of the electronic circuits. ...Performing imaging experiments in a 3 T scanner showed an 8% increased signal-to-noise ratio from 365 to 399 when lowering the temperature of the preamplifier from 296 to 77 K while keeping the coil at room temperature. ...

Enhancement of Magnetic Resonance Imaging with Metasurfaces.
Slobozhanyuk AP, et al. Adv Mater 2016. Among authors: Raaijmakers AJ. PMID 26754827
It is revealed that the unique properties of ultrathin metasurface resonators can improve magnetic resonance imaging dramatically. A metasurface formed when an array of metallic wires is placed inside a scanner under the studied object and a substantial enhancement of the radio-frequency magnetic field is achieved by means of subwavelength manipulation with the metasurface, also allowing improved image resolution....

Magnetic resonance imaging.
Carr MW and Grey ML. Am J Nurs 2002 - Review. PMID 12473927
[Use of magnetic resonance imaging].
Chabanova E, et al. Ugeskr Laeger 2014 - Review. PMID 24629608 Danish.
Magnetic resonance imaging (MRI) is one of the four imaging modalities used in radiology. In contrast to computed tomography (CT), it does not use radiation. ...There are many indications for MRI and in some fields it has replaced CT. With few exceptions MRI is used mainly for elective examinations, and because of the new techniques like diffusion and perfusion MRI in cancer imaging the use is increasing both with regard to work-up and follow-up. ...

Magnetic resonance imaging at ultrahigh fields.
Ugurbil K. IEEE Trans Biomed Eng 2014 - Review. PMID 24686229 Free PMC article.
Since the introduction of 4 T human systems in three academic laboratories circa 1990, rapid progress in imaging and spectroscopy studies in humans at 4 T and animal model systems at 9.4 T have led to the introduction of 7 T and higher magnetic fields for human investigation at about the turn of the century. ...Primary difference from lower fields is the deviation from the near field regime; at the frequencies corresponding to hydrogen resonance conditions at ultrahigh fields, the RF is characterized by attenuated traveling waves in the human body, which leads to image nonuniformities for a given sample-coil configuration because of interferences. ...

A low-cost, high-field-strength magnetic resonance imaging-compatible actuator.
Secoli R, et al. Proc Inst Mech Eng H 2015. Among authors: Rodriguez y Baena F, Robinson M. PMID 25833997
To perform minimally invasive surgical interventions with the aid of robotic systems within a magnetic resonance imaging scanner offers significant advantages compared to conventional surgery. However, despite the numerous exciting potential applications of this technology, the introduction of magnetic resonance imaging-compatible robotics has been hampered by safety, reliability and cost concerns: the robots should not be attracted by the strong magnetic field of the scanner and should operate reliably in the field without causing distortion to the scan data. ...

Cardiac magnetic resonance imaging for the investigation of cardiovascular disorders. Part 2: emerging applications.
Goenka AH, et al. Tex Heart Inst J 2014 - Review. PMID 24808772 Free PMC article.
Cardiac magnetic resonance imaging has emerged as a robust noninvasive technique for the investigation of cardiovascular disorders. The coming-of-age of cardiac magnetic resonance-and especially its widening span of applications-has generated both excitement and uncertainty in regard to its potential clinical use and its role vis-à-vis conventional imaging techniques. ...

Opportunities and Challenges of 7 Tesla Magnetic Resonance Imaging: A Review.
Karamat MI, et al. Crit Rev Biomed Eng 2016 - Review. PMID 27652452
The desire to achieve clinical ultra-high magnetic resonance imaging (MRI) systems stems from the fact that higher field strength leads to higher signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR), and spatial resolution. ...The engineering and scientific community have to overcome challenges like magnetic field inhomogeneity, patient safety and comfort issues, and cost and related problems in order to achieve a clinically viable UhFMRI system. ...

Compact Magnetic Resonance Imaging Systems-Novel Cost-Effective Tools for Preclinical Drug Safety and Efficacy Evaluation.
Ramot Y, et al. Toxicol Sci 2017. PMID 28329801
Practical magnetic resonance imaging for use in investigative and preclinical toxicology studies is now feasible. Newly developed, self-containing imaging systems provide an efficient and cost-effective means to rapidly obtain in vivo and ex vivo magnetic resonance imaging images to improve how we perform toxicology and toxicologic pathology....
