MRI quantifies magnetic targeting of tumors

August 20, 2018 -- To avoid the adverse impact of chemotherapy on healthy tissue, a useful targeting mechanism is to magnetically guide nanocarriers of toxic drugs to tumors using an applied magnetic field. The method is cheap and easy, but it lacks a quantifiable way of evaluating targeting efficiency. Discuss

French mammography usage soars after national rollout

August 17, 2018 -- Once breast cancer screening went national in France, takeup of mammography rose by 12%, a study published online on 6 August revealed. The effects were particularly significant among women with less education and lower incomes, suggesting the program reduced socioeconomic disparities. Discuss

MRI helps find contact lens embedded in eye for 28 years

August 17, 2018 -- With the help of MRI, ophthalmologists in the U.K. were able to discover what was causing eyelid swelling in a 42-year-old woman: a hard contact lens that had been embedded in her eye for 28 years. The bizarre case was published on August 10 in BMJ Case Reports. Discuss

5 risk factors help predict brain hemorrhage on CT

August 17, 2018 -- U.K. researchers have identified five factors -- including contrast leakage on CT scans -- that may indicate a higher risk of continued bleeding in the brain of stroke patients. Checking for these factors may help improve survival, according to an article published online on August 14 in Lancet Neurology. Discuss

Prescan tutorial eases patient concerns about PET/CT

August 16, 2018 -- Giving patients knowledge of what to expect from an upcoming FDG-PET/CT scan can go a long way toward helping them to relax and improving their experience, according to a study published online August 3 in the Journal of Nuclear Medicine Technology. Discuss

Computer scientists may hold trump cards in AI's future

August 15, 2018 -- Unlike traditional areas of research that require clinician supervision, investigations of artificial intelligence (AI) imaging are likely to be driven by computer scientists, and this may restrict the input of radiologists and sit uncomfortably with them, writes Dr. Simon Wong. Discuss

DBT's benefits vary between Europe and the U.S.

August 15, 2018 -- A new meta-analysis has reaffirmed the value of digital breast tomosynthesis (DBT) for breast screening, with DBT detecting more cancers with fewer recalls. But DBT's effect varied significantly between the U.S. and Europe, according to results published online August 9 in the Journal of the National Cancer Institute. Discuss

3D printing facilitates complex spinal surgery

August 14, 2018 -- Dutch researchers have developed a workflow involving 3D virtual and 3D-printed models that may change how complex spinal surgeries are managed. Using this new technique, surgeons were able to repair a 12-year-old girl's severe and debilitating spinal deformity. Discuss

Flat-panel CT proves value in temporal bone

August 14, 2018 -- Flat-panel CT of the temporal bone yields higher image quality than 128-slice CT with comparable overall effective doses, according to an Italian study published in the September edition of the European Journal of Radiology. Discuss

Micro-CT enhances resolution of 3D-printed models

August 13, 2018 -- Offering more than 100 times the image resolution of MRI and CT, micro-CT may serve as an alternative to standard imaging modalities in the production of 3D-printed models -- especially for tiny, complex structures, according to research from London's leading pediatric center.
