Ultra-High Field MRI Clinical Anatomy of the Equine Fetlock to Aid Clinical Image Interpretation

High field MRI in clinical practice.

Magnetic resonance imaging and spectroscopy can provide detailed morphologic, functional and metabolic information that may provide unique biomarkers to assist drug discovery and development. To overcome the inherent low signal to noise of in vivo magnetic resonance applications, stronger magnetic field strengths can be applied that not only boost signal strengths, but can also be used to impro...

Feasibility of Using Ultra-High Field (7 T) MRI for Clinical Surgical Targeting

The advantages of ultra-high magnetic field (7 Tesla) MRI for basic science research and neuroscience applications have proven invaluable. Structural and functional MR images of the human brain acquired at 7 T exhibit rich information content with potential utility for clinical applications. However, (1) substantial increases in susceptibility artifacts, and (2) geometrical distortions at 7 T w...

Evaluation of the Equine Acute Abdomen Patient in the Field: Interpretation of Historical and Clinical Findings

Dielectric Resonance in Ultra High Field MRI

INTRODUCTION Since the start of magnetic resonance imaging, there has been a constant drive towards more powerful magnets and consequently higher operational frequencies. For head imaging, it is expected for the electromagnetic fields to be influenced by the presence of the tissue at these frequencies (field strength AT). As a result, fundamental problems were anticipated regarding the presence...

Ultra-High Field Cardiovascular MRI: Challenges

The realization of the potential advantages of 7T cardiovascular MRI is challenging due to a number of technical and practical issues (1). For example, the clinical application of 7T MRI is limited by safety issues related to stents and other devices. Many patients with ischemic heart disease have undergone previous stent implantation and extensive safety testing is required before these patien...
