New MR Technique May Help Save Women from Unnecessary Breast Biopsies

A new MR procedure that uses diffusion-weighted imaging (DWI) to determine whether or not a breast lesion is malignant or benign may help reduce unnecessary breast biopsies, according to a study performed at the National Institute of Health in Bethesda, MD. DWI is a method that produces images detecting the exchange of water molecules between tissue compartments (diffusion).

The study included 80 patients with 85 lesions. Quantitative analysis of DWI was used to determine whether or not a lesion was benign or malignant. “Using diffusion-weighted imaging can reflect the cellular density of a lesion without using contrast,” said Riham El-Khouli, MD, lead author of the study.

“The quantitative analysis of DWI correctly identified that 50 of 60 lesions as malignant. At the same time, it correctly identified that 23 of 25 of the lesions were benign. Lesions with higher cellular density are more likely to be malignant,” she said.

“MR imaging of the breast is very common. It is typically used for screening patients with an increased risk of developing breast cancer (patients with a personal or family history of breast or ovarian cancer and patients with certain genetic mutations). It is also used for some patients who have been recently diagnosed with breast cancer or for patients with complex mammograms,” said Dr. El-Khouli.

This new MR method that uses diffusion-weighted imaging only adds to the benefits of using MR for breast imaging by improving the ability of MRI to characterize benign from malignant lesions. Hopefully, this procedure will help save women from unnecessary breast biopsies by decreasing the false-positive rates of MRI,” said Dr. El-Khouli.

This study will be presented at the 2009 ARRS Annual Meeting in Boston, MA, on Wednesday, April 29. For a copy of the full study, please contact Heather Curry via email at

About ARRS

The American Roentgen Ray Society (ARRS) was founded in 1900 and is the oldest radiology society in the United States. Its monthly journal, the American Journal of Roentgenology, began publication in 1906. Radiologists from all over the world attend the ARRS annual meeting to participate in instructional courses, scientific paper presentations and scientific and commercial exhibits related to the field of radiology. The Society is named after the first Nobel Laureate in Physics, Wilhelm Röentgen, who discovered the x-ray in 1895.

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
