Siemens RSNA launches range from x-ray to PET/CT December 1, 2015 -- CHICAGO - At this week's RSNA 2015 meeting, Siemens Healthcare is unveiling a range of new imaging technologies, from a robotic x-ray room to a new entry-level PET/CT scanner. The firm is also talking up a regulatory clearance for CT lung cancer screening that it received just before the show opened.
Researchers measure fetal CT dose with SSDE November 30, 2015 -- CHICAGO - A new fetal dose-measurement technique ties CT dose index volume scanner readouts to size-specific dose estimates (SSDEs), opening a door to greater accuracy in fetal dose measurement, according to a presentation at the 2015 RSNA meeting.
FDG-PET/CT study suggests change in breast cancer guidelines November 29, 2015 -- CHICAGO - FDG-PET/CT's aptitude for finding distant metastases in patients with stage III invasive ductal carcinoma has prompted researchers to suggest that the National Comprehensive Cancer Network add histology to its guidelines for determining the best staging method.
Breast MR finds significant cancer that mammo misses November 25, 2015 -- Additional breast cancers found with MRI after mammography can be larger and more aggressive -- and may prompt a change in a patient's treatment plan, according to a new study published in Radiology.
FDA says film printing optional for mammography November 23, 2015 -- In a guidance to mammography facilities, the U.S. Food and Drug Administration (FDA) said that printing breast images to hard-copy film is no longer necessary and can be performed at the discretion of individual centers.
Forget Watson -- it's the pigeons you should worry about November 18, 2015 -- If you think artificial intelligence could replace radiologists someday, there may be a new menace: It turns out that pigeons can distinguish benign from malignant tissue and identify certain cancer features with similar accuracy as their human counterparts, according to a new study published in PLOS One.
DBT cuts recall rate in women with no prior mammograms November 13, 2015 -- Digital breast tomosynthesis (DBT) cuts the number of recalls in a subset of women vulnerable to higher recall rates: those who have never had a prior mammogram, according to a new study in the November issue of the American Journal of Roentgenology.
Breast ultrasound helps mammography find more cancer November 5, 2015 -- Adding ultrasound to mammography screening detects more early invasive breast cancer and probably reduces mortality, according to a 4 November study in the journal Lancet. The Japanese trial is thought to be the first of its kind in a large, randomized, multicenter population with a focus on younger, average-risk women.
Use vascular indexes to exclude malignant breast masses November 4, 2015 -- Using vascular indexes obtained via 3D power Doppler ultrasound can accurately characterize suspicious breast masses, and adding it to 2D ultrasound may reduce unnecessary biopsies, noted Turkish researchers in an article published online in the European Journal of Radiology.
DBT finds 54% more cancers than mammography October 30, 2015 -- Digital breast tomosynthesis (DBT) finds 54% more cancers than 2D mammography and reduces recall rates by almost 20%, according to a new study published in Radiology. Even better, the technology identifies lesions in dense breast tissue, which mammography tends to miss.
