The benefits of performing fMRI when planning stereotactic radiosurgery (SRS) in patients with primary or secondary brain tumors are discussed, along with the necessary information regarding implementation protocols.

New scanning assistance systems are needed if radiologists and imaging providers are to cope with the increasing demand and the high expectations of quality while only having a limited workforce, with our initial experience using myExam Autopilot described.
[...]
Technical advances in cardiovascular magnetic resonance (CMR) enable both qualitative and quantitative assessment of myocardial inflammation non-invasively.
[...]
Cardiovascular magnetic resonance (CMR) plays a growing role in therapeutic decision-making as it allows differentiation of etiologies and provides prognostic information.
[...]
High acceleration factors using standard CAIPIRINHA acceleration for cartesian trajectories, in combination with a modern iterative denoising (ID) reconstruction algorithm, can be applied to 3D SPACE, maintaining image sharpness with high SNR, for either reduced scan time or higher spatial resolution.
[...]
Moving to higher magnetic fields may not always be advantageous in MRI, with sufficient SNR now available on new state of the art low field systems, which feature many advantages not the least of which are reduced artifacts and lower cost.
[...]
MRF represents a paradigm shift for reliable, repeatable, and consistent signal acquisition and modeling. The recent availability of this technique in the clinical realm may have a significant impact on tumor detection, characterization, and effective treatment planning.

Mixing different training formats (blended learning) is a key feature of learning today, and it has become even more important since the COVID-19 pandemic began.

This article provides an overview of MR-guided breast biopsy performed using the Breast Biopsy software, syngo MR XA20 version (Siemens Healthcare, Erlangen, Germany).
[...]
We show that signal and contrast can both be improved using 3D SPACE with CAIPIRINHA acceleration combined with a prototype iterative denoising algorithm in comparison to the standard SPACE sequence and reconstruction.
[...]
Image quality in standard 2D MRI sequences, accelerated in simulation beyond the threshold of standard acceptable noise levels, can be substantially improved by applying an iterative denoising algorithm using supplementary information about the image noise level.
[...]
Deep Resolve Gain and Deep Resolve Sharp introduce targeted, iterative denoising and deep learning reconstruction into clinical imaging. These technologies enable us to reduce acquisition times and improve image quality simultaneously.
[...]
This overview shows how a complete design overhaul of the magnet and gradient system together with the use of new imaging and reconstruction techniques results in an MRI system that achieves somewhat contradictory goals: A large 80 cm bore for the patient with a scanner that delivers diagnostic image quality AND easy installation with a small physical footprint and low connection power.

This review discusses first the background in terms of development of these agents and safety discussions therein, proceeds to a discussion of NSF and gadolinium deposition in the brain, and concludes with a discussion of the predictable future – specifically reassessment of the use of the linear GBCAs or a subset thereof.
[...]
The DryCool magnet is a highly innovative development which incorporates many new technologies and concepts. The magnet delivers the first 80 cm patient bore in the industry and is a key enabler for the ground-breaking MAGNETOM Free.Max MRI scanner. The magnet minimizes product life-cycle costs and total cost of ownership and virtually eliminates the complex superconducting magnet servicing procedures.
