Example-Based Restoration of High-Resolution Magnetic Resonance Image Acquisitions

2013
Increasing scan resolution in magnetic resonance imaging is possible with advances in acquisition technology. The increase in resolution, however, comes at the expense of severe image noise. The current approach is to acquire multiple images and average them to restore the lost quality.

High resolution magnetic resonance imaging at low-field (0.1 Tesla)

Proceedings of the Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 1992
This paper presents a specific instrumentation for High Resolution Imaging at 0.1 Tesla. The new system includes a surface high strength magnetic field gradient, a Radio-Frequency coil cooled by liquid Nitrogen, and the signal reception system. The original geometry of the high resolution module allows us to image the human whole-body surface.

High-resolution magnetic resonance imaging of the ankle: normal anatomy

Skeletal Radiology, 1986
An imaging-anatomic correlative study of ankle anatomy based upon six healthy adults and six fresh cadaveric specimens was performed to evaluate the diagnostic capabilities of magnetic resonance imaging (MRI). Optimal pulsing sequences and imaging planes for various structures of interest were established.

High-resolution magnetic resonance imaging of the wrist: normal anatomy

Skeletal Radiology, 1987
Magnetic resonance imaging (MRI) provided adequate depiction of carpal soft tissue structures in normal volunteers, as well as accurate anatomic correlation with cadaveric specimens. Using a high field strength system and surface coil techniques, the intricate anatomy of the wrist was best defined on long TR short TE images.

High-resolution optically-detected magnetic resonance imaging in an ambient magnetic field

Journal of Magnetic Resonance, 2013
Magnetic resonance imaging (MRI) in an ultralow magnetic field usually has poor spatial resolution compared to its high-field counterpart. The concomitant field effect and low signal level are among the major causes that limit the spatial resolution.

Consecutive Imaging of the Facial Nerve using High-Resolution Magnetic Resonance Imaging

Acta Oto-Laryngologica, 2000
This study examined the signal intensity of the facial nerve on T1-weighted images using the multiplanar reconstruction (MPR) method of the high-resolution magnetic resonance imaging technique. The facial nerves of 12 sides in 6 normal adults were consecutively observed from the mastoid area to the intraparotid area.

Assessment of Trabecular Structure Using High Resolution Magnetic Resonance Imaging

1997
Although bone mineral density is one of the most important contributing factors to bone strength and risk of fracture, studies have shown that changes in bone quality and structure independent of bone mineral density, influence both bone strength and individual risk of fracture.
