Latest Advances and Applications of Magnetic Resonance Imaging

Dear Colleagues,

Since its conception in the 1970s and first clinical utilization in the 1980s, magnetic resonance imaging (MRI) has been developed into an indispensable diagnostic and research tool. MRI has the unique advantages of being non-ionizing while providing cross-sectional or 3-dimensional images with excellent soft tissue contrast. Over the years, advances in MRI hardware (e.g., magnet, radiofrequency coils, gradient coils), pulse sequences, computing capability, and reconstruction/processing algorithms have widely broadened MRI applications by providing numerous techniques such as diffusion/perfusion imaging, angiography, contrast-enhanced dynamic studies, real-time cardiac imaging, fat fraction measurement, and elastography of the liver. In addition to its diagnostic applications, MRI has also been proven useful for biomedical research, such as studies of brain functions and connectivity using functional MRI (fMRI) or diffusion tensor imaging (DTI), animal modeling studies of disease processes and treatment outcomes, as well as nonmedical applications, such as in the food industry.

In recent years, MRI technological advances have been made in the utilization of artificial intelligence, compress sensing, parallel imaging, simultaneous multislice or a combination of these techniques to achieve faster image acquisition and to improve image quality through the reduction of image artifacts or noise and increase in spatial resolution. MR fingerprinting is another emerging technology that reduces scan time by quantifying multiple MR tissue properties from a single scan. New advances and applications in MRI are also being made in MRI hardware and pulse sequences. Examples include technical developments and applications on 7T or higher field systems and the utilization of ultrashort echo-time sequences for lung or bone imaging.

This Special Issue focuses on the latest advances and applications of magnetic resonance imaging. We invite researchers and investigators to contribute original research or review papers to this Special Issue.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
