Neurosurgery gets boost from 3D-printed head model
August 16, 2019 -- An Australian team has devised a 3D-printed head model that enables the realistic simulation of neurosurgical procedures. The technique is based on a combination of MRI and CT angiography scans, and it is described in an online report posted on 1 August by 3D Printing in Medicine.  Discuss
Italians find mammography can show cardiovascular disease
August 15, 2019 -- Italian researchers have found that mammography can be a useful way to test for cardiovascular disease at the same time as screening for breast cancer because it identifies breast arterial calcifications, which have been linked to cardiovascular disease risk. They published their results online on 11 August in the European Journal of Radiology.  Discuss
Radiology chief at Karolinska issues rebuttal to Maverinck
August 14, 2019 -- The managing director for imaging and physiology at Karolinska University Hospital, Dr. Juhana Hakumäki, PhD, responds to last week's Maverinck column about the controversy swirling around recent construction at the world-famous hospital in Stockholm.  Discuss
Is it time to get serious about the placenta?
August 14, 2019 -- Significant advances are occurring in placental MRI -- particularly the development of texture analysis, machine learning, and radiomic approaches -- and the time is now ripe for systematic and detailed MRI scans of the placenta in pregnancy, a leading French expert believes.  Discuss
Support grows for mpMRI before prostate biopsy
August 13, 2019 -- A U.K. study has shown that the use of multiparametric MRI (mpMRI) in suspected cases of prostate cancer can cut unnecessary biopsies by more than a third and boost the detection of clinically significant disease by more than 50%. The findings were published online on 7 August in JAMA Network Open.  Discuss
Doctors find dentures in man's throat 8 days after surgery
August 13, 2019 -- Removable dentures got stuck in a 72-year-old man's throat during surgery to remove a benign lump. Doctors didn't find the false teeth until eight days later when the patient complained of pain, bleeding, and swallowing difficulties.  Discuss
AI displays potential for breast ultrasound
August 12, 2019 -- Artificial intelligence (AI) algorithms can yield a promising level of performance for differentiating between benign and malignant solid breast masses on B-mode ultrasound images, but further improvement is still needed, according to research published online on 5 August in European Radiology Experimental.  Discuss
Austrians make full use of AI to determine bone age
August 9, 2019 -- Researchers from Austria have found that an artificial intelligence (AI) algorithm can estimate bone age accurately in children and adolescents from the analysis of a 3D hand MRI exam. The technique also performs well on wrist radiographs, they noted in an article posted online on 31 July in Medical Image Analysis.  Discuss
Holographic lenses focus ultrasound for brain imaging
August 8, 2019 -- Better brain imaging, or even drug delivery, may be feasible due to the pioneering work of Spanish researchers. They have developed a technique for 3D printing holographic lenses that focus ultrasonic sound waves in the brain.  Discuss
What's gone wrong at the Karolinska?
August 7, 2019 -- Regular articles continue to appear in Swedish newspapers about the huge building and corruption scandal at the New Karolinska Hospital. Many doctors are leaving, patients are suffering, and some observers think the scandal is so large that it can never be thoroughly investigated. The Maverinck tells the story.  Discuss
