CT, MRI for lower back pain still prevalent in ED

January 24, 2020 -- The rate of CT and MRI scans for back pain remained steady from 2001 to 2016 despite efforts to curtail unnecessary imaging tests in emergency departments (EDs) for lower back pain, according to a study published in the February issue of the American Journal of Roentgenology.

3D printing helps mummy speak from beyond the grave

January 24, 2020 -- Have you ever wondered what it would be like to hear a mummy speak? It's now possible thanks to the magic of CT and 3D printing technology, which has enabled the re-creation of the distinct voice of an ancient Egyptian who's been dead for centuries. The process is detailed in a January 23 article in Scientific Reports. Discuss

Elastography shows high reproducibility in breast lesions

January 24, 2020 -- Two different ultrasound elastography techniques -- strain elastography and shear-wave elastography -- showed high interoperator reproducibility when scanning breast lesions in a new study, published on January 21 in Ultrasound in Medicine and Biology. Discuss

#MyRadGirlfriend No. 102: The show

January 24, 2020 -- With so much happening in the world, sometimes it can be hard to keep up. Ryan and Andy have slightly different perspectives on the top events of the day in the next installment of #MyRadGirlfriend. Discuss

Should cancer centers ban the bell?

January 24, 2020 -- Bells have become commonplace within oncology centers as a means to allow cancer patients to mark the end of their course of treatment. But is it time to ban the bell? A new study published in International Journal of Radiation Oncology, Biology, Physics suggests it might. Discuss

2 ultrasound features predict cancer recurrence risk

January 23, 2020 -- Machine learning might one day be able to tell which breast cancer patients will benefit from additional genetic testing. In a recent study, researchers used natural language processing to identify key features from ultrasound reports associated with cancer recurrence risk. Discuss

Biomarkers on PET, MRI show breast cancer risk

January 23, 2020 -- In a finding they described as "unexpected," researchers used PET and MRI to discover that women with a malignant tumor in one breast have lower levels of certain biomarkers in the contralateral, healthy breast. Results were published in the January edition of the Journal of Nuclear Medicine. Discuss

High calcium density on CCTA linked to lower risk of ACS

January 22, 2020 -- High levels of plaque calcification on coronary CT angiography (CCTA) scans were associated with a lower risk of acute coronary syndrome (ACS) and adverse cardiac events for individuals suspected of having heart disease in an international study published online January 22 in JAMA Cardiology. Discuss

Deep learning of x-rays helps predict pulmonary blood flow

January 22, 2020 -- A deep-learning algorithm that analyzed chest x-rays was able to predict pulmonary to systemic blood flow just as well as clinicians. The finding could give healthcare providers a better way to determine which patients with congenital heart disease require intervention, according to a January 22 article in JAMA Cardiology. Discuss

Unique PET/CT video shows real-time blood, cardiac motion

January 22, 2020 -- U.S. and Chinese researchers have combined an advanced image reconstruction method with a total-body PET scanner to track real-time blood flow and heart and respiratory function, according to a study published online January 20 in the Proceedings of the National Academy of Sciences.
