MR spectroscopy identifies breast cancer, reduces biopsies
By Dross at 2007-09-25 21:41
 

OAK BROOK, Ill.—Proton magnetic resonance spectroscopy (¹H MRS) used in conjunction with magnetic resonance imaging (MRI) can aid radiologists in diagnosing breast cancer while reducing the number of false-positive results and invasive biopsies, according to a study focusing on non-mass enhancing breast lesions. The study, conducted at Memorial Sloan-Kettering Cancer Center in New York City, appears in the October issue of the journal Radiology.

“All of the cancers present in this study were identified with MR spectroscopy,” said the study’s lead author, Lia Bartella, M.D., director of breast imaging at Eastside Diagnostic Imaging in New York City.

How Proton Treatment Works
By Dross at 2007-03-14 02:04
 

There is a significant difference between standard (x-ray) radiation treatment and proton therapy. If given in sufficient doses, x-ray radiation techniques will control many cancers. But, because of the physician's inability to adequately conform the irradiation pattern to the cancer, healthy tissues may receive a similar dose and can be damaged. Consequently, a less- than-desired dose is frequently used to reduce damage to healthy tissues and avoid unwanted side effectsterm. The power of protons is that higher doses of radiation can be used to control and manage cancer while significantly reducing damage to healthy tissue and vital organs.
