Detailed Anatomy at 7T

, 2017
This chapter illustrates high resolution images obtained from a 7T scanner. These images provide detailed visualization of deep gray nuclei, hippocampus and temporal lobe anatomy not normally seen on 1.5T or 3T scanner imaging. Axial and coronal planes have been used to provide detailed regional anatomy.

7T Imaging of the Wrist

Seminars in Musculoskeletal Radiology, 2012
Ultra-high-field magnetic resonance (MR) imaging provides a high signal-to-noise ratio and thus is expected to be superior to 1.5T and 3T MR systems that are currently used in daily routine. For use in the musculoskeletal system, expectations are high, particularly for smaller joints such as the wrist, because of the small size of the visualized ...

Magnetic Resonance Safety in the 7T Environment

Magnetic Resonance Imaging Clinics of North America, 2020
The arrival of 7T MR imaging into the clinic represents a significant step-change in MR technology. This article describes safety concerns associated with imaging at 7T, including the increased magnetic forces on magnetic objects at 7T and the interaction of the 300 MHz (Larmor) radiofrequency energy with tissue in the body.

Repeatability of APTw imaging at 7T

ISMRM Annual Meeting, 2023
APTw imaging is a potential imaging biomarker to assess treatment effects in brain tumours, especially at high field MRI (7T) due to improved signal-to-noise-ratio enabling the assessment of APTw values in heterogenous tumours. Embedding of APTw imaging in clinical decision making requires insight in the repeatability of APTw imaging.

Artificial dielectric for 7T MRI

AIP Conference Proceedings, 2020
This article present a new approach replacing high-permittivity water-based dielectric pads with a non-resonant low-cost artificial dielectric to improve MR image quality by modifying the interferences present in the radiofrequency field at 7T MRI. The artificial dielectric comprises a stack of metal patches printed on dielectric substrates.

A 7T Security Oriented SRAM Bitcell

IEEE Transactions on Circuits and Systems II: Express Briefs, 2019
Power analysis (PA) attacks have become a serious threat to security systems by enabling secret data extraction through the analysis of the current consumed by the power supply of the system. Embedded memories, often implemented with six-transistor static random access memory (SRAM) cells, serve as a key component in many of these systems.

7T: Physics, safety, and potential clinical applications

Journal of Magnetic Resonance Imaging, 2017
With more than 60 installed magnetic resonance imaging (MRI) systems worldwide operating at a magnetic field strength of 7T or higher, ultrahigh‐field (UHF) MRI has been established as a platform for clinically oriented research in recent years. Profound technical and methodological developments have helped overcome the inherent physical challenges of ...

A closer look: pediatric neuroimaging at 7T

Pediatric Radiology
Although 7 Tesla (7T) field strength MR imaging offers higher signal-to-noise ratio and spatial resolution and improves certain types of tissue contrast, the incorporation of these systems into clinical pediatric neuroradiology has been relatively limited.
