If a mammogram or sonogram suggests that a woman has breast cancer, an MRI should be done to help determine whether there actually is a cancer and if so, what are the woman’s best treatment options, a new study shows. The study, done in a large community hospital, found that MR images, which were acquired and analyzed in a specific way, can help identify if a lesion is benign or malignant and can show cancers that would otherwise be missed.
“This is the first time a prospective study has been done that shows that MRI (using a contrast agent) can work in a real life community setting - the setting in which most breast cancer patients are diagnosed and treated,” said Jonathan I. Wiener, MD, lead author of the study. The study included 65 patients who had “highly suspicious” findings on mammography or sonography and were believed to be candidates for breast conserving treatment. Nineteen of the patients did not have a suspicious lesion on MRI, and when these women were biopsied, it turned out they did not have cancer, said Dr. Wiener. Many of those patients could have avoided having a biopsy at all, he said.
In addition, MRI detected 23 additional cancers in the 44 patients that actually had a breast cancer (either in the same breast as the primary cancer and or in the opposite breast) that were not detected on mammography or sonography. Because of the additional information provided by MRI, and subseqently confirmed by pathological analysis of the biopsy specimens, it was recommended that eight women have a mastectomy rather than breast conservation treatment. “About 15% of breast cancer patients have a recurrence of their disease. We don’t know precisely why cancer returns in previously thought to be adequately treated breast cancer patients. One of the reasons could be that many of the cancers may be missed initially with only a conventional work up with mammography and ultrasound. The addition of MRI will improve the accuracy of breast cancer diagnosis,” Dr. Wiener said.

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
