A sound approach to fibroids

Date: Apr 1, 2010

Author: David Bradley

A new interventional radiology tool based on using MRI to guide focused high-energy ultrasound could be used to thermally ablate uterine fibroid tissue and relieve symptoms of this condition without major invasive surgery.

Fat and water magnetic resonance imaging

Date: Mar 23, 2010

Author:

A wide variety of fat suppression and water-fat separation methods are used to suppress fat signal and improve visualization of abnormalities. This article reviews the most commonly used techniques for fat suppression and fat-water imaging.

MRI on the ball

Date: Mar 1, 2010

Author: David Bradley

MRI proves to be a good diagnostic tool for testicular cancer and could spare some men unnecessary surgery.

Pinpointing prostate problems without surgery

Date: Feb 15, 2010

Author: David Bradley

Magnetic resonance spectroscopy, the molecular cousin of MRI could be used to pinpoint the exact location of prostate cancers and to determine the aggressiveness of a tumour, according to research published in the Science Translational Medicine. The approach could help guide treatment.

Red lenses

Date: Feb 1, 2010

Author: David Bradley

US scientists have used MRI to show that apparently the less you use your brain's frontal lobes, the more you perceive your behaviour through rose-tinted spectacles. They publish details in the February issue of the journal NeuroImage.

MRS of the occipital cortex and the cerebellar vermis distinguishes individual cats affected with alpha-mannosidosis from normal cats

Date: Jan 25, 2010

Author:

In vivo MRS from the cerebellar vermis and occipital cortex of cats with alpha mannosidosis (AMD) demonstrated a broad signal between 3.4 - 4.3 ppm (arrowed) from undigested oligosaccharides, which was not observed in normal cats. High-resolution NMR spectra of perchloric acid extracts confirmed the presence of accumulated oligosaccharides along with increased resonances from Glc-NAc and anomeric sugar protons in tissues from AMD cats. This characteristic MRS pattern may be used for diagnosis and treatment...

MRI nanoparticles seek and destroy cancer cells

Date: Jan 1, 2010

Author: David Bradley

A single nanoparticle can be tracked using real-time MRI as it homes in on cancer cells. A fluorescent dye used to tag the nanoparticle couples with heat therapy to kill the targeted cells.

Diffusion tensor imaging of the human calf muscle

Date: Dec 22, 2009

Author:

Diffusion tensor imaging can display diffusional anisotropy of tissue. Possibly, proton diffusivity within the highly ordered musculature will change with muscle length since the cross sectional area of the muscle increases with shortening. Results show that the fractional anisotropy significantly decreases and the mean diffusion increases with muscle shortening.

MRI reveals BMI as bogus heart health indicator

Date: Dec 1, 2009

Author: David Bradley

Body mass index, BMI, is not a reliable indicator of overall fitness for obese individuals as assessed by internal, or visceral, fat. An MRI and NMR study reveals that fat accumulation in different parts of the body, such as around the heart and the aorta and within the liver, is associated with decreased heart function, but BMI offers no correlation for this problem.

The development of the birdcage resonator: a historical perspective

Date: Nov 24, 2009

Author:

This personal account, taken from the current special 'coils' issue of NMR in Biomedicine, charts the development of the birdcage resonator, covering the historic context of early MRI development.
