Magnetic resonance neurography

The Lancet, 1993
Radiological methods exist for generating tissue-specific images of bone, vessels, lymphatics, abdominal viscera, and the central nervous system, but there has been no reliable means to generate a clinical image of a nerve. We present the first "image neurogram" and report a method for producing such images by use of commercial magnetic resonance ...

MAGNETIC RESONANCE CHOLANGIOGRAPHY

Gastroenterology Clinics of North America, 1995
MR cholangiography offers a noninvasive method of obtaining images of the biliary system without the use of a contrast agent. There is no radiation exposure. Pulse sequences can be chosen to obtain bright bile or black bile cholangiograms. Image processing algorithms can be selected to obtain a three-dimensional representation of biliary anatomy and ...

Magnetism and magnetic resonance

2006
Abstract in which are developed the fundamental physics of the single isolated magnetic dipole, materials as ensembles of such dipoles, their resonant behaviour, and magnetic field measurements. This provides the under lying physics for chapter 7.

[Cerebrovascular pathology. Comparison of magnetic resonance and magnetic resonance angiography].

La Radiologia medica, 1991
After making the visualization of the intracranial circulation possible without contrast media, the radiologist is now evaluating the diagnostic role of the different techniques of MRA. Attempts are also being made to characterize the main patterns of intracranial vascular diseases.

Magnetic resonance mammography

BMJ, 2010
Routine use in newly diagnosed breast cancer patients is unsupported Magnetic resonance imaging enables high definition scanning of tissue without the use of ionising radiation. In the past decade it has become widely used in breast imaging and is a sensitive method of visualising the breast parenchyma and highlighting areas of pathology.

Magnetic resonance lymphography

Current Opinion in Urology, 2007
The current methods of noninvasively staging retroperitoneal lymph nodes are suboptimal. Magnetic resonance lymphography is a new technique that might offer an important new tool in this area. Although it is still in development, more and more studies show that it is highly effective in detecting nodal metastases of various tumors.Magnetic resonance ...

The principles of magnetic resonance

British Medical Bulletin, 1989
Magnetic Resonance (MR), which has no known biological hazard, is capable of producing high resolution thin tomographic images in any plane and blocks of 3-dimensional information. It can be used to study blood flow and to gain information about the composition of important materials seen and quantified on dimensionally accurate images. The MR image is

Magnetic resonance angiography

Medical Journal of Australia, 1993
To outline the physical principles of magnetic resonance angiography (MRA), major current MRA techniques, clinical indications and some of the limitations of MRA. The rapidly changing nature of MRA techniques is stressed.The MRA literature for the last eight years is reviewed with particular attention to the changing clinical role of MRA.

Accessible magnetic resonance imaging: A review

Journal of Magnetic Resonance Imaging, 2019
The role of MRI in diagnostics, prognostics, and discoveries in basic sciences has been well established. However, access to this life‐saving technology is largely restricted to countries in upper‐middle to high‐income groups. In this article, we collate

Magnetic Resonance Neurography

Magnetic Resonance in Medicine, 1992
AbstractWe have made cross‐sectional image “neurograms” in which peripheral nerve has a greater signal intensity than that of other tissue. Neurographic images of the rabbit forelimb were obtained using a spin‐echo magnetic resonance imaging (MRI) technique that combines fat suppression and diffusion weighting.
