3T MRI fetal scans should not affect newborns' hearing
January 12, 2018 -- When pregnant mothers are scanned with 3-tesla MRI, the higher noise levels relative to 1.5-tesla scanners do not seem to increase the risk that their babies will have hearing problems after birth, according to new research from Boston Children's Hospital and the Children's Hospital of Philadelphia.  Discuss
Should chest CT scans be reviewed for breast lesions?
January 12, 2018 -- What should be done with incidental breast lesions detected in women receiving chest CT exams? A new study recommends not only that these lesions be followed up, but also that a new reporting scale similar to BI-RADS be used to classify the findings, according to results published in Clinical Imaging.  Discuss
CMS to ease rules for MRI scans of implantable devices
January 11, 2018 -- Reimbursement could soon get a lot easier for MRI scans of patients with implantable cardiac devices. The U.S. Centers for Medicare and Medicaid Services (CMS) on January 11 proposed withdrawing its requirement that payments for these scans only be made when the scans are performed within a clinical study.  Discuss
CCTA predicts heart events in stable chest pain patients
January 11, 2018 -- By detecting high-risk plaque, coronary CT angiography (CCTA) can predict major adverse cardiovascular events in patients with stable chest pain, according to a January 10 study in JAMA Cardiology. But the jury is still out on whether CCTA findings should be added to risk stratification tools such as Framingham scores.  Discuss
Artificial intelligence guides lower PET tracer dose
January 11, 2018 -- In PET imaging, the amount of radiotracer dose correlates with the level of image quality. But what if artificial intelligence (AI) could enable PET to be performed using only 1% of current dose levels -- speeding exam times, decreasing radiation exposure, lowering costs, and alleviating shortages in radiotracers?  Discuss
#MyRadGirlfriend No. 54: Cold weather blues
January 11, 2018 -- The cold weather is already starting to get old at Children's Hospital, where Andy finds she has to cope with a deluge of weather-related injuries. And Priya's no help, in the next installment of #MyRadGirlfriend.  Discuss
3D-printed breast biopsy device boosts accuracy
January 10, 2018 -- Researchers from the Netherlands have developed a 3D-printed robot-guided device capable of facilitating MR-guided breast biopsy and improving the accuracy of breast cancer diagnosis. Biopsies can even be performed inside the MRI scanner.  Discuss
Multiparametric MRI can help avoid renal mass biopsies
January 10, 2018 -- Researchers at the University of Texas Southwestern have discovered that radiologists using multiparametric MRI have an 80% chance of detecting clear cell carcinoma in the kidneys without the need for a confirming biopsy. In addition, the technique was successful among radiologists with varying levels of expertise.  Discuss
FDA guidance urges lower radiation dose for kids
January 10, 2018 -- The U.S. Food and Drug Administration (FDA) on January 9 issued a new guidance urging healthcare providers to use the lowest radiation dose possible when performing medical imaging exams on children.  Discuss
Both screening, treatment cut breast cancer deaths
January 9, 2018 -- Which factor -- screening or treatment -- has been behind the sharp reduction in breast cancer mortality over the past several decades? A new study published January 9 in the Journal of the American Medical Association found that the answer is simple: both.  Discuss
