New technology predicts effectiveness of chemotherapy after one treatment

While early detection of breast cancer is critical, early prediction of how well the neoadjuvant chemotherapy treatment before surgery is working also may provide a window of opportunity when treatment could be altered and have a big impact on the patient's quality of life.

Neuroimaging technology used to study how brain stimulation works for treatment of depression

Repetitive transcranial magnetic stimulation, or rTMS, was FDA approved in 2008 as a safe and effective noninvasive treatment for severe depression resistant to antidepressant medications. A small coil positioned near the scalp generates repetitive, pulsed magnetic waves that pass through the skull and stimulate brain cells to relieve symptoms of depression.

Critical improvements to functional Near Infrared Spectroscopy enhance brain imaging

In an article published today in the peer-reviewed, open-access SPIE publication Neurophotonics, "High density functional diffuse optical tomography based on frequency domain measurements improves image quality and spatial resolution," researchers demonstrate critical improvements to functional Near Infrared Spectroscopy (fNIRS)-based optical imaging in the brain.

Photoacoustics could become alternative to mammography or sonogram for breast cancer detection

One of the lines of research of OILTEBIA, a European science project coordinated by Universidad Carlos III de Madrid, is a method to detect breast cancer based on photoacoustics and which could become an alternative to mammography or sonogram.

New optical approach to brain scanning for patients with electronic implants

Scientists have advanced a brain-scanning technology that tracks what the brain is doing by shining dozens of tiny LED lights on the head. This new generation of neuroimaging compares favorably to other approaches but avoids the radiation exposure and bulky magnets the others require, according to new research at Washington University School of Medicine in St. Louis.

Combination of optical and x-ray imaging may improve diagnostic accuracy of breast screening

By combining optical and x-ray imaging, radiologists may be better able to distinguish cancer from benign lesions in the breast, according to a new study published in the online edition and January issue of Radiology.

Tests at five beta sites validate CEA-Leti’s new fDOT imaging system for commercialization

CEA-Leti today announced that after extensive beta testing at five French research facilities, its new imaging system for near-infrared fluorescence-enhanced diffuse optical tomography (fDOT) is ready for commercial applications.

Ultrasound-guided diffuse optical tomography holds promise for ascertaining early-stage invasive breast cancer

By combining two relatively inexpensive technologies based on sound and light waves, researchers hope to lower the rate at which women undergo breast biopsies for suspicious lesions. Results of the study on ultrasound-guided optical tomography are published in the online edition and the August print issue of Radiology.

University of Arkansas to host the 2010 Advances in Breast Cancer Research workshop

The University of Arkansas will host the 2010 Advances in Breast Cancer Research workshop sponsored by the National Science Foundation on Oct. 26-29. The workshop will bring together researchers in nanotechnology, biomagnetics, microwave imaging, acoustics, laser and biochemistry fields with researchers from radiology, oncology and breast surgery.

Non-invasive "optical biopsy" to detect breast cancer

Most biopsies following mammograms reveal benign abnormalities, not cancer.

Researchers tune Diffuse Optical Tomography for early detection of breast cancer

Clemson University researchers in collaboration with researchers at the University of Bremen, Germany, are working to make the physical pain and discomfort of mammograms a thing of the past, while allowing for diagnostic imaging eventually to be done in a home setting.

High-density diffuse optical tomography helps scan infant brains

Researchers hoping to better understand the development of the infant brain have long been stymied by a formidable obstacle: babies just don't want to sit still for brain scans.

Researchers create first 3-D optical images of human breast cancer in patients based on tissue fluorescence

Fluorescence diffuse optical tomography, or FDOT, relies on the presence of fluorophore molecules in tissue that re-radiate fluorescent light after illumination by excitation light of a different color.
