AI predicts myocardial infarction, death in patients at risk of CAD
May 13, 2019 -- By analyzing clinical and hybrid imaging data, an artificial intelligence (AI) algorithm can predict which patients will go on to experience myocardial infarction or death during long-term follow-up, according to research from Finland presented at this week's International Conference on Nuclear Cardiology and Cardiac CT in Lisbon.  Discuss
How to train the medical physicists of the future
May 10, 2019 -- At the recent European Society for Radiotherapy and Oncology meeting in Milan, a debate examined the skills that medical physicists will require in 10 years' time and asked how training for medical physicists specializing in radiation oncology should develop over the next decade. Five expert speakers presented their thoughts -- and then let the audience decide.  Discuss
AI-based FFR-CT software offers robust performance
May 8, 2019 -- Different CT tube voltage levels didn't hinder the performance of a prototype artificial intelligence (AI) algorithm for estimating fractional flow reserve on coronary CT angiography (FFR-CT), according to a study by a multinational research group published on 30 April in the American Journal of Roentgenology.  Discuss
AI can help facilitate gadolinium-free cardiac MRI
May 7, 2019 -- Chinese and U.K. investigators have developed an artificial intelligence (AI) algorithm that can detect chronic myocardial infarction on noncontrast-enhanced cardiac cine MRI. This might avoid the need for gadolinium-based contrast, according to an article posted online on 30 April in Radiology.  Discuss
New breast CAD advances detection with MRI, PET
May 3, 2019 -- Researchers from Austria have developed a new computer-aided segmentation and diagnostic (CAD) algorithm to distinguish between cancerous and benign breast lesions using PET and MRI data. Their study was published online on 27 April in European Radiology Experimental.  Discuss
Voice recognition: Informatics experts give their view
May 1, 2019 -- How much of an effect do voice recognition programs have on radiologists' efficiency? How can the technology be improved? The jury is still out on these systems, it seems, and some health IT specialists remain convinced there is significant room for improvement.  Discuss
AI can segment white-matter hyperintensities on MRI
April 22, 2019 -- Artificial intelligence (AI) algorithms are capable of segmenting cerebral white-matter hyperintensities of presumed vascular origin on brain MR images as well as or better than human observers, enabling more reliable quantification of these lesions, according to the results of a recent AI developer challenge.  Discuss
Can AI help radiologists detect prostate cancer?
April 18, 2019 -- A team of researchers from the U.S. has developed an artificial intelligence (AI) algorithm that could enable less-experienced radiologists to better detect prostate cancer on multiparametric MRI. The group reported the findings at the recent IEEE International Symposium on Biomedical Imaging in Venice, Italy.  Discuss
Ultrasound CADx software can stratify thyroid nodules
April 15, 2019 -- Researchers from Spain found that ultrasound computer-aided diagnosis (CADx) software could -- despite some limitations -- offer value in stratifying the malignancy risk of thyroid nodules, according to a study published on 11 April in the American Journal of Roentgenology.  Discuss
Swiss team finds AI can aid breast ultrasound reads
April 10, 2019 -- An artificial intelligence (AI) algorithm matched the performance of radiologist readers in detecting and classifying lesions on breast ultrasound exams, investigators from Switzerland reported in research published online on 29 March in European Radiology.  Discuss
