Nuclear imaging using radiotracers can deliver radiation to more than just the patients, according to a study published in the Journal of the American College of Cardiology. Patients may emit small doses of radiation for a short time, potentially posing a problem for people such as clinicians who have regular exposure. "[O]ur data suggest that close and repeated contact should be avoided in populations that are more radiosensitive, such as pregnant women and children," researchers wrote. Measures that can reduce exposure include planning echocardiograms before nuclear procedures, delaying some tests and wearing a lead vest.
Texas Children's Hospital has acquired a PET/MRI system from Philips Healthcare, making it the first children's hospital to use the hybrid device. The tool will be used as part of clinical trials aiming to establish the combined modality's effectiveness in pediatric patients. The FDA has approved the device for adult patients.
New Jersey legislators are considering a bill that would make health insurers pay for additional tests if mammogram data indicate a patient has dense breast tissue. "A mammogram will detect only about 48% of tumors in women with dense breast tissue, meaning the rest will elude early detection," said Assemblyman Troy Singleton, D-Burlington, a sponsor of the bill. Connecticut and Illinois have similar legislation, said Are You Dense Advocacy President Nancy Cappello.
A Journal of Nuclear Medicine study that used SPECT imaging with I-123 PE21 found that binding of the tracer to the dopamine transporter system did not show a clear link with signs of Lewy body dementia. "Our results suggest that the general level of cognitive impairment in DLB patients is not influenced by striatal dopaminergic dysfunction," researchers said. However, they noted more research is needed to substantiate their findings.
Carestream Molecular Imaging, a unit of Carestream Health, has entered into an exclusive, multi-year global deal with Spanish firm OncoVision concerning the sale, marketing and servicing of the Albira PET/SPECT/CT imaging system for use in small-animal research. The Albira system allows for fast acquisition and reconstruction of high-resolution PET and SPECT images.
