SCCA to raise awareness about importance of lung cancer screening

Lung cancer is the No. 1 cause of cancer deaths in the United States, despite the fact it is largely preventable. For people at high risk of developing lung cancer, such as current or former longtime smokers, screening for the disease with low-dose CT scans is now a viable option that has been shown to significantly reduce mortality rates. In conjunction with National Lung Cancer Awareness Month, Seattle Cancer Care Alliance (SCCA) wants to raise awareness about the importance of prevention and early detection for at-risk populations.

Mayo Clinic receives FDA approval for Choline C 11 Injection to help detect prostate cancer

Mayo Clinic has received U.S. Food and Drug Administration approval to produce and administer Choline C 11 Injection, an imaging agent used during a positron emission tomography (PET) scan to help detect sites of recurrent prostate cancer. Mayo Clinic is the first, and currently only, institution in North America approved to produce this imaging agent.

Study reveals increased risk of leukemia among Chernobyl cleanup workers

A 20-year study following 110,645 workers who helped clean up after the 1986 Chernobyl nuclear power plant accident in the former Soviet territory of Ukraine shows that the workers share a significant increased risk of developing leukemia. The results may help scientists better define cancer risk associated with low doses of radiation from medical diagnostic radiation procedures such as computed tomography scans and other sources.

EUROECHO 2012 reveals how imaging improves early diagnosis of atherosclerosis

"Atherosclerosis is the leading cause of cardiovascular disease and the leading killer in Europe," said Professor Patrizio Lancellotti, President-Elect of the EACVI and Chairman of the EUROECHO Scientific Programme Committee. "Many of these deaths could be averted by diagnosis at a preclinical stage or early after the onset of symptoms."

Phantom caries revealed?

Microcomputed tomography of teeth can detect demarcated radiolucencies below the enamel–dentin junction that are of noncarious origin, and can therefore be classified as possible developmental irregularities, show study results.

Technology creates 3-D map of stresses linked to malformed structures

Researchers at Case Western Reserve University have found a way to create three-dimensional maps of the stress that circulating blood places on the developing heart in an animal model - a key to understanding triggers of heart defects.

UWCCC enrolls first patient in Phase 1-2 PET imaging trial of LIGHT for solid tumors

Novelos Therapeutics, Inc., a pharmaceutical company developing novel drugs for the treatment and diagnosis of cancer, today announced that the University of Wisconsin Carbone Cancer Center, a leading oncology research institution, has enrolled the first patient in a Phase 1-2 positron emission tomography (PET) imaging trial of I-124-CLR1404, a cancer-targeted PET imaging agent, in patients with nine solid tumor types, including triple negative breast, soft tissue sarcoma, colorectal, gastric, esophageal, prostate, ovarian, pancreatic and head & neck cancer.

Omega-3 fatty acid can enhance cognition in highly functional young individuals

While Omega-3 essential fatty acids-found in foods like wild fish and grass-fed livestock-are necessary for human body functioning, their effects on the working memory of healthy young adults have not been studied until now.

Scientists develop new breast cancer screening method with less radiation

Scientists have developed a way to produce three-dimensional X-ray images of the breast at a radiation dose that is lower than the 2D radiography methods used in clinics today. The new method enables the production of 3D diagnostic computed tomography (CT) images with a spatial resolution 2-3 times higher than present hospital scanners, but with a radiation dose that is about 25 times lower.

Combination of phase contrast tomography and EST can produce high-quality 3D breast images

Like cleaning the lenses of a foggy pair of glasses, scientists are now able to use a technique developed by UCLA researchers and their European colleagues to produce three-dimensional images of breast tissue that are two to three times sharper than those made using current CT scanners at hospitals. The technique also uses a lower dose of X-ray radiation than a mammogram.
