October 21, 2019 -- If you're a smoker and want to cut your chances of dying from cancer by smoking a "light" brand of cigarette, think again. Researchers found no difference in lung cancer mortality between those who smoked light cigarettes and those who puffed regular smokes, according to a study published on October 21 in JAMA Internal Medicine.

USA Today: DBT's value unproven, but marketing vigorous

October 21, 2019 -- Mammography centers in the U.S. have rapidly adopted 3D mammography -- also known as digital breast tomosynthesis (DBT) -- despite the lack of large-scale clinical trials demonstrating the technology's value, according to an investigation by Kaiser Health News that was published in USA Today.

Is PET really necessary to predict oncoming Alzheimer's?

October 21, 2019 -- Can a person's progression from mild cognitive impairment to Alzheimer's be reliably predicted without PET imaging? A new study published online October 18 in the Journal of Nuclear Medicine lists several nonimaging methods that could offer a better prognosis than the modality. Discuss

Why EMRs will not replace imaging IT

October 18, 2019 -- The growing influence and uptake of electronic medical records (EMRs) in healthcare has driven debate over the future role of clinical and diagnostic software for specialists. In radiology, questions are arising about the future of imaging IT applications such as PACS. Don't look for imaging IT to go away anytime soon, however, according to Steve Holloway of Signify Research. Discuss

IMV: Imaging boosts precision in radiation therapy

October 17, 2019 -- Radiation therapy is a relatively stable market, with procedure volume growing at an average annual rate of 2%. But major technological changes in radiation oncology are brewing under the surface, such as the growing use of imaging, according to a new report by IMV Medical Information Division. Discuss

MRI shows concussion effects last longer than thought

October 17, 2019 -- MR images have revealed lingering abnormalities in the brains of concussed athletes more than a year after they were cleared to return to competition, which could mean the injuries have not yet completely healed, according to a study published online on October 16 in Neurology. Discuss

DBT finds more cancers of all types than FFDM

October 17, 2019 -- Digital breast tomosynthesis (DBT) has a higher cancer detection rate compared with full-field digital mammography (FFDM). And DBT's improved performance persists no matter the tumor type, size, or grade of cancer, according to a study published online October 16 in the American Journal of Roentgenology. Discuss

fMRI maps show dementia spreading through brain networks

October 16, 2019 -- Brain maps based on functional MRI (fMRI) scans are proving useful in predicting the spread of brain atrophy that leads to progressive dementia, according to a study published October 14 in Neuron. Discuss

Do steroid injections into joints do more harm than good?

October 15, 2019 -- X-ray imaging shows that corticosteroid injections for osteoarthritis pain in the hip and knee may actually damage the joints, leading to more rapid progression of the disease and eventually joint collapse, according to a study published online October 15 in Radiology. Discuss
