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
Italians use AR to bolster prostate cancer surgery
May 6, 2019 -- Italian researchers have used augmented reality (AR) technology to overlay dynamic virtual 3D models based on MRI scans directly onto patient anatomy. In a recent article in European Urology, they found their method to be highly effective for prostate cancer surgery.  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
Lung ultrasound shows promise in pulmonary TB
May 2, 2019 -- In suspected cases of pulmonary tuberculosis (TB) where radiation dose is of great concern, particularly in younger patients, lung ultrasound is a valid, noninvasive, and cost-effective tool compared with chest CT, new research from Italy has found.  Discuss
Portable ultrasound proves effective at bedside for elderly
May 2, 2019 -- Using a portable, handheld ultrasound device at the bedside for elderly patients works just as well as a regular, high-end ultrasound system for diagnosing disease and therefore clarifying treatment options, according to a German study published on 26 April in the European Journal of Ultrasound.  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
U.K. team uses CT method to assess pulmonary ventilation
April 30, 2019 -- Using a CT-based computational model to determine the ventilation heterogeneity of chronic obstructive pulmonary disease with increased detail can improve the stratification of these patients according to their disease severity and evaluate their suitability for regional treatment, researchers from Oxford, U.K., have found.  Discuss
Contrast mammo equals MRI for measuring tumor size
April 30, 2019 -- Korean researchers have found that contrast-enhanced digital mammography works just as well as contrast-enhanced breast MRI for measuring breast tumors before surgery, according to a study published on 24 April in the British Journal of Radiology.  Discuss
ESTRO: U.K. group finds favor with high-dose brachytherapy
April 30, 2019 -- In a study presented on Monday at the European Society for Radiotherapy and Oncology (ESTRO) meeting in Milan, U.K. researchers found that a single session of high-dose-rate brachytherapy safely treated prostate cancer in men, proving especially effective in low-risk cases.  Discuss
Augmented reality helps guide uterine tumor surgery
April 29, 2019 -- Researchers from France have used augmented reality technology to overlay 3D models based on MRI scans onto a real-time video of the uterus, helping clinical staff to locate tumors and determine the best approach for their surgical removal. The results were recently published online in the Journal of Minimally Invasive Gynecology.  Discuss
