Red lenses
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
[registered users only]
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 monitoring of AMD.

MRI nanoparticles seek and destroy cancer cells
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.
