MRE reduces ionizing radiation exposure, detects Crohn's disease as reliably as CT

A new study from Rhode Island Hospital has found that MR enterography (MRE) without the use of an anti-peristaltic agent were as reliable as CT enterography (CTE) in determining the presence of Crohn's disease.

Telethermographic device is not approved for screening breast cancer

The U.S. Food and Drug Administration today warned women not to substitute breast thermography for mammography to screen for breast cancer.

Cell phone use poses no cancer risk, says JunkScience publisher

Today's media hoopla about the World Health Organization classifying cell phone use as "possibly carcinogenic" is much ado about nothing. The studies the WHO relies on are weak association studies that have zero reliability.

Cell phones and cancer – link established

In its latest announcement the World Health Organization (WHO) said that radiation from cell phones can possibly cause cancer. According to the WHO's International Agency for Research on Cancer (IARC), radiofrequency electromagnetic fields have been classified as possibly carcinogenic to humans (group 2B) on the basis of an increased risk for glioma that some studies have associated with the use of wireless phones.

Artificial ionizing radiation enhances impairment of humankind's genetic pool

Ionizing radiation is not without danger to human populations. Indeed, exposure to nuclear radiation leads to an increase in male births relative to female births, according to a new study by Hagen Scherb and Kristina Voigt from the Helmholtz Zentrum München.

Global scientists rebuke coming decision on carcinogenicity of radiofrequency and microwaves

In collaboration with the International EMF Alliance (IEMFA), scientists from Europe, North America, Australia and Israel have sent an Open Letter to Dr. Christopher Wild, Director of the International Agency for Research on Cancer (IARC), calling for a postponement of the forthcoming meeting May 24-31, 2011 in Lyon, France, “Non-Ionizing Radiation, Part II: Radiofrequency Electromagnetic Field [includes mobile telephones],” at which determination of the carcinogenicity of cell phones and wireless technologies will be made.

New image-processing software allows significant radiation dose reduction

A reduction by half in the radiation dose to which cardiac patients are exposed during diagnostic perfusion imaging is now "feasible", according to an Israeli study.

Tanning solariums exposing people to UV radiation six times the strength of midday sun: Study

According to the latest research, tanning sun beds can deliver wildly different doses of UV radiation, with some exposing users to levels up to six times the strength of the midday sun. Worst part of it that most users are unaware of this say experts. An audit of beds in Sydney and Melbourne found some deliver twice the dose of radiation as others classed in lower categories. The audits took place in Victoria and NSW.

New ACR Dose Index Registry allows imaging community to measure effectiveness of dose lowering efforts

Medical imaging facilities can now submit anonymized dose information for all CT exams performed to the Dose Index Registry (DIR) — allowing them to compare their dose indices to other facilities of similar size or geographic area and to national benchmarks. Participating facilities receive periodic feedback comparing their dose levels to these benchmarks, enabling them to make any necessary adjustments to lower dose received from scans.

Study provides information about hematuria in microscopic urinalysis and urinary tract cancer

Hematuria or blood in the urine may trigger a battery of tests for urinary tract cancer that are invasive and can unnecessarily expose patients to radiation, yet the procedures contribute little to the diagnosis, according to a study by Kaiser Permanente Southern California's Department of Research & Evaluation published in the May issue of the Journal of Urology.

Chest CT more effective for preoperative cardiothoracic surgery patients

Recent studies have shown that a 64-detector CT angiography utilizing prospective electrocardiographic gating produces a quality image but considerably reduced patient radiation dose when compared to retrospective ECG gating, according to research being presented at the 2011 American Roentgen Ray Society's annual meeting.

Thomas Jefferson University receives award to develop novel radiation drugs

Shortly before Japan's devastating nuclear incident, researchers at Thomas Jefferson University and Hospitals received an award to find novel drugs to treat people exposed to dangerous amounts of radiation in the wake of a nuclear terrorist attack or a nuclear accident.

Acetyl resveratrol could protect against radiation sickness

In the midst of ongoing concerns about radiation exposure from the Fukushima nuclear power plant in Japan, scientists are reporting that a substance similar to resveratrol - an antioxidant found in red wine, grapes and nuts - could protect against radiation sickness. The report appears in ACS Medicinal Chemistry Letters.

FDA clears Sectra's digital mammography system

Women in the US will now have the same opportunity as million of European women already have; to undergo mammography with significantly lower radiation dose. This is the result of FDA's clearance of the Swedish IT and medical technology company Sectra's digital mammography system, Sectra MicroDose Mammography.

Experts to review how environmental disasters affect children's health

Environmental disasters can affect children's health in unique ways, both physically and psychologically. In two sessions at the Pediatric Academic Societies annual meeting at the Colorado Convention Center in Denver, Colo., experts in pediatric health care from the U.S. and Japan will examine the toll of two recent disasters on children's health: the 2011 earthquake, tsunami and nuclear crisis in Japan; and the 2010 Gulf of Mexico oil spill.
