Breast Cancers Show “Surprising Characteristics” on MRI

06.05.2004


MRI can effectively detect cancers missed by mammography and physical examination, but cancers can have some surprising characteristics on the MR image, a new study shows.



The study included 59 women with 65 cancers that were not detected by physical examination or on a mammogram, said Lia Bartella, MD, assistant professor of radiology at Memorial Sloan-Kettering Cancer Center in New York. The classic criteria for cancer on an MR image is a mass that looks bright after contrast media is injected into the breast, but it quite quickly loses its brightness, said Dr. Bartella. “In 63% of these patients, this didn’t happen,” she said. The mass took up the contrast, but there was no quick washout,” she said. One lesion showed progressive kinetics, which means that it got brighter and brighter on the MR image. This often happens when the lesion is benign, Dr. Bartella said. In addition, Dr. Bartella noted that in 62% of the cases, the cancer did not look like a mass.

Most of the cancers (70%) were stage 1 disease; 28% were stage 2, and 2% of the women had distant metastases, indicating that MRI can detect breast cancer at an early stage, said Dr. Bartella. Most of the women (68%) had a mastectomy, Dr. Bartella said. It is important to note that these women chose mastectomy; MRI offered most of them the chance to have breast-conserving treatment because their disease was caught early, she said.


These women were sent for an MRI examination for several reasons –13 of the women were at high risk of breast cancer; 41 of the women had known breast cancer, and the MRI was done to determine the extent of disease; and five of the women had an MRI after a problem was detected, but physicians were unsure of the diagnosis, said Dr. Bartella.

Dr Bartella will present the study on May 6 at the American Roentgen Ray Society Annual Meeting in Miami Beach, FL.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
