MR-EYE: High-Resolution MRI of the Human Eye and Orbit at Ultrahigh Field (7T)
Ultrahigh-field (7T) MRI provides improved contrast and a signal-to-noise gain compared with lower magnetic field strengths. Here, we demonstrate feasibility and optimization of anatomic imaging of the eye and orbit using a dedicated commercial multichannel transmit and receive eye coil. Optimization of participant setup techniques and MRI sequence parameters allowed for improvements in the image resolution and contrast, and the eye and orbit coverage with minimal susceptibility and motion artifacts in a clinically feasible protocol.

UltraHigh Field MR Imaging in Epilepsy
More than one million people in the United States suffer from seizures that are not controlled with antiseizure medications. Targeted interventions such as surgery and deep brain stimulation can confer seizure reduction or even freedom in many of these patients with drug-resistant epilepsy, but success critically depends on identification of epileptogenic zones through MR imaging. Ultrahigh field imaging facilitates improved sensitivity and resolution across many imaging modalities and may facilitate better detection of epileptic markers than is achieved at lower field strengths. The increasing availability and clinical ad...

Progress in Imaging the Human Torso at the Ultrahigh Fields of 7 and 10.5  T
Especially after the launch of 7  T, the ultrahigh magnetic field (UHF) imaging community achieved critically important strides in our understanding of the physics of radiofrequency interactions in the human body, which in turn has led to solutions for the challenges posed by such UHFs. As a result, the originally obtained poor im age quality has progressed to the high-quality and high-resolution images obtained at 7 T and now at 10.5 T in the human torso. Despite these tremendous advances, work still remains to further improve the image quality and fully capitalize on the potential advantages UHF has to off...

High-Resolution Neurovascular Imaging at 7T
Ultrahigh field offers increased resolution and contrast for neurovascular imaging. Arterial spin labeling methods benefit from an increased intrinsic signal-to-noise ratio of MR imaging signal and a prolonged tracer half-life at ultrahigh field, allowing the visualization of layer-dependent microvascular perfusion. Arterial spin labeling –based time-resolved 4-dimensional MR angiography at 7T provides a detailed depiction of the vascular architecture and dynamic blood flow pattern with high spatial and temporal resolutions. High-resolution black blood MR imaging at 7T allows detailed characterization of small perfor...

Perivascular Space Imaging at Ultrahigh Field MR Imaging
The recent Food and Drug Administration approval of 7  T MR imaging scanners for clinical use has introduced the possibility to study the brain not only in physiologic but also in pathologic conditions at ultrahigh field (UHF). Because UHF MR imaging offers higher signal-to-noise ratio and spatial resolution compared with lower field clinical scanners , the benefits of UHF MR imaging are particularly evident for imaging small anatomic structures, such as the cerebral perivascular spaces (PVS). In this article, the authors describe the application of UHF MR imaging for the investigation of PVS. (Source: Magnetic Resona...

Dynamic Glucose-Enhanced MR Imaging
Conventional medical imaging techniques use contrast agents that are chemically labeled, for example, iodine in the case of computed tomography, radioisotopes in the case of PET, or gadolinium in the case of MR imaging to create or enhance signal contrast and to visualize tissue compartments and features. Dynamic glucose-enhanced MR imaging represents a novel technique that uses natural, unlabeled d-glucose as a nontoxic biodegradable contrast agent in chemical exchange –sensitive MR imaging approaches.

MR Imaging Safety Considerations of Gadolinium-Based Contrast Agents
Gadolinium (Gd)-based contrast agents (GBCAs) have revolutionized of MR imaging, enabling physicians to obtain life-saving medical information that often cannot be obtained with unenhanced MR imaging or other imaging modalities. Since regulatory approval in 1988, more than 450 million intravenous GBCA doses have been administered worldwide, with an extremely favorable pharmacologic safety profile. Recent evidence has demonstrated, however, that a small fraction of Gd is retained in human tissues. No direct correlation between Gd retention and clinical effects has been confirmed; however, a subset of patients have attribute...

Elements of Effective Patient Screening to Improve Safety in MRI
Conducting magnetic resonance imaging (MRI) safety screening is not a new idea and has developed as a proved method in efforts to ensure patient safety and prevent accidents in the magnetic resonance (MR) environment. A growing number of surgical procedures with implanted medical devices have complicated MR screening and added to the workload of Level 2 personnel. Level 2 staff members are trained to understand and implement screening procedures and should be consulted by all individuals requiring access to the MR environment.

MR Safety
New implanted medical devices continue to be made available for treatment of medical conditions. Many recipients can benefit from the diagnostic power of MR imaging. Provisions must be made to determine if these patients can be safely scanned. Metal-containing devices can be considered either MR unsafe or conditional. It is essential that all components of an implanted system are completely and accurately identified, with the most restrictive MR safety condition dictating the scanning approach. MR safety considerations for major classes of implanted devices are discussed, recognizing that there have been reports of serious...

Foreword
Dr Meng Law beautifully framed this issue as “7.0 T versus 3.0 T.” The only addition I would make is “7.0 T versus 1.5 T,” since the majority of magnets in use globally are 1.5 T. There has been a gradual transition to 3.0 T, but not as rapidly as once predicted due to a myriad of reasons. The question is whether 7.0 T is ready for “ prime time.” (Source: Magnetic Resonance Imaging Clinics of North America)

Standardized Approaches to MR Safety Assessment of Patients with Implanted Devices
Three dimensionally mapping the relative spatial distributions and magnitudes of the various energy sources used in the MR imaging process for a given MR scanner potentiates an understanding of the relative spatial distributions of the potential risks associated with each of these energies or fields. By systematically analyzing the data for each energy source relative to the location and type of implants, devices, and/or foreign bodies within a specific patient, one can prospectively assess and even begin to quantify the risks of exposing that patient to selected MR scanner hardware for a requested diagnostic study.

MRI is a powerful diagnostic tool with excellent soft tissue contrast that uses nonionizing radiation. These advantages make MRI an appealing modality for imaging the pregnant patient; however, specific risks inherent to the magnetic resonance environment must be considered. MRI may be performed without and/or with intravenous contrast, which adds further fetal considerations. The risks of MRI with and without intravenous contrast are reviewed as they pertain to the pregnant or lactating patient and to the fetus and nursing infant.

MR Imaging Safety
Although comparatively much younger as a discipline, these early decades of the structure of practice of MR imaging safety have developed in an alarmingly ad hoc manner, particularly when contrasted with contemporary ionizing radiation safety. This absence of structure and metrics for MR imaging safety has impaired the direct safety best practices for the recognizable domains of clinical and operational MR safety. If the built environment of MR imaging is effectively the hardware of the mechanism of health care delivery, then the appropriateness of this hardware to the software (clinical and operational practices) is of gr...
