magnetic resonance imaging

(Polytechnique Montréal) Known for being the world's first researcher to have guided a magnetic sphere through a living artery, Professor Martel is announcing a spectacular new breakthrough in the field of nanomedicine.

Using a magnetic resonance imaging system, his team successfully guided microcarriers loaded with a dose of anti-cancer drug through the bloodstream of a living rabbit, right up to a targeted area in the liver, where the drug was successfully administered.

(Radiological Society of North America) Using functional magnetic resonance imaging, researchers have captured pictures of the brain while patients experienced a pain stimulus with and without acupuncture to determine acupuncture's effect on how the brain processes pain.

(American College of Radiology / American Roentgen Ray Society) An overwhelming majority of Breast Cancer Surveillance Consortium (BCSC) facilities performing breast magnetic resonance imaging (MRI) in the U.S. are up-to-par with American College of Radiology Imaging Network (ACRIN) and European Society of Breast Imaging (EUSOBI) technical standards and requirements, according to a study in the November issue of the Journal of the American College of Radiology (www.jacr.org).

(Emory University) Tiny particles of iron oxide could become tools for simultaneous tumor imaging and treatment, because of their magnetic properties and toxic effects against brain cancer cells.

In mice, researchers have demonstrated how these particles can deliver antibodies to implanted brain tumors, while enhancing tumor visibility via magnetic resonance imaging.

(Deutsches Aerzteblatt International) Thanks to technical progress, there are now new areas in which whole body magnetic resonance imaging can be used.

In the current edition of Deutsches Arzteblatt International, Gerwin Schmidt and his coauthors present a review of possible uses, together with the limits of this radiation-free diagnostic procedure.

(University of California - Los Angeles) UCLA researchers used structural magnetic resonance imaging to show for the first time that individuals whose mothers abused methamphetamine during pregnancy (with or without alcohol abuse) had brain structural abnormalities that were more severe than in children whose mothers abused alcohol alone.

The researchers identified what brain structures are vulnerable, which may help predict particular learning and behavioral problems in meth-exposed children.

(Radiological Society of North America) Annual breast cancer screening with both mammography and magnetic resonance imaging is likely to be a cost-effective way to improve life expectancy in women with an increased risk of breast cancer, according to a new study.

The findings support current American Cancer Society screening recommendations.

(American College of Radiology / American Roentgen Ray Society) Researchers have found that non-invasive magnetic resonance imaging (MRI) is a good diagnostic tool for the evaluation and staging of testicular cancer and may improve patient care by sparing some men unnecessary surgery, according to a study in the March issue of the American Journal of Roentgenology.

(American College of Radiology / American Roentgen Ray Society) Contrast-enhanced magnetic resonance imaging may help physicians differentiate between rheumatoid arthritis and psoriatic arthritis in the hand and wrist enabling more targeted therapies unique to each condition, according to a study in the March issue of the American Journal of Roentgenology.

Contrast-enhanced MRI uses contrast media to improve the visibility of internal bodily structures.

(American College of Radiology / American Roentgen Ray Society) The new recommendations from the Society of Breast Imaging and the American College of Radiology on breast cancer screening, published in the January issue of the Journal of the American College of Radiology, state that breast cancer screening should begin at age 40 and earlier in high-risk patients.

The recommendations also suggest appropriate utilization of medical imaging modalities such as mammography, magnetic resonance imaging, and ultrasound for breast cancer screening.
