Peter B. Bach, M.D., of the Memorial Sloan-Kettering Cancer Center, New York, and colleagues conducted a systematic review to examine the evidence regarding the benefits and harms of low-dose computerized tomography (LDCT) screening for lung cancer, which is the leading cause of cancer death. "Most patients are diagnosed with advanced disease, resulting in a very low 5-year survival rate," the authors write. "Renewed enthusiasm for lung screening arose with the advent of LDCT imaging, which...

Researchers have developed multiple techniques and procedures to detect cancer cells during the earliest stages of the disease or after treatment. But one of the major limitations of these technologies is their inability to detect the presence of only a few cancer cells. Now, a research collaboration between the University of Missouri-Columbia and Mexico's Universidad de Guanajuato shows that pulsed photoacoustic techniques, which combine the high optical contrast of optical tomography...

Photoacoustic tomography can 'see' in color and detail several inches beneath the skin Every new imaging technology has an aura of magic about it because it suddenly reveals what had been concealed, and makes visible what had been invisible. So, too, with photoacoustic tomography, which is allowing scientists to virtually peel away the top several inches of flesh to see what lies beneath. The technique achieves this depth vision by an elegant marriage between light and sound, combining...

For assessing severe trauma, single-pass whole-body computed tomography (CT) can prove but not definitively exclude the presence of injuries and should be performed later than 30 minutes after admission to an emergency department for optimal results, according to a study in CMAJ (Canadian Medical Association Journal). Traumatic injury, caused by major traffic collisions or a fall from a height, for example, has a significant impact on health care costs, illness and death. In North America...

Scientists at the Centre for Addiction and Mental Health (CAMH) have identified a potential target for the development of anti-craving medications for people with addictions to stimulants such as methamphetamine. The discovery centers on a brain receptor related to the chemical dopamine, which has a complex role in addictive behaviors. Using brain scans and a novel chemical probe developed in CAMH's Research Imaging Centre, CAMH scientists found that the probe had high levels of binding...

Facilitates systematic comparison of mouse models of disorders including schizophrenia, autism A new technology developed by neuroscientists at Cold Spring Harbor Laboratory (CSHL) transforms the way highly detailed anatomical images can be made of whole brains. Until now, means of obtaining such images — used in cutting-edge projects to map the mammalian brain -- have been painstakingly slow and available only to a handful of highly specialized research teams. By automating and...


Word of the Day
cenobite
  • One of a religious order living in a convent or in community; a monk: opposed to anchoret or hermit (one who lives in solitude).
