Is your MRI scanner the weak link in your security plan? July 28, 2017 -- Cybersecurity for medical imaging equipment is often more critical than for other medical devices because the equipment stores protected health information and communicates directly with PACS and electronic medical record systems. This makes imaging equipment an attractive target for hackers, as it provides the perfect portal to a hospital's most valuable asset: patient information.
CT CAC scoring tops age for predicting heart disease risk July 27, 2017 -- Is age just a number? Maybe, at least for predicting atherosclerotic cardiovascular disease events in older adults. Coronary artery calcium (CAC) scoring with CT is better than a patient's age for predicting risk -- particularly for coronary heart disease, according to research published online July 26 in JAMA Cardiology.
Neonates show no adverse effects from CT, MRI contrast July 27, 2017 -- A review of inpatient neonates suggests that babies with normal renal function who receive iodine-based CT or gadolinium-based MRI contrast agents have no greater risk of renal toxicity than those not receiving contrast, according to results published in the August issue of Radiology.
Point-of-care ultrasound shows its merit July 27, 2017 -- While conventional diagnostic ultrasound understandably offers higher sensitivity and specificity, point-of-care ultrasound can yield a valuable level of accuracy for low-resource settings, according to research published in the July issue of the Journal of Ultrasound in Medicine.
DBT does not boost BI-RADS 3 category use July 26, 2017 -- Screening with digital breast tomosynthesis (DBT) doesn't increase the use of BI-RADS category 3 -- a designation that prompts intensive follow-up and tracking for up to two years and can provoke anxiety in patients, according to a study published online July 17 in Radiology.
3D printing helps evaluate leaks after TAVR procedures July 26, 2017 -- 3D-printed phantoms of aortic root anatomy offer a noninvasive way to assess the risk of a patient experiencing a leak after transcatheter aortic valve replacement (TAVR), according to a study published in the July issue of JACC: Cardiovascular Imaging.
Canadian head CT rule reduces unnecessary exams July 26, 2017 -- Using the Canadian CT Head Rule to assess the need for imaging after trauma in community emergency departments reduces unnecessary exams by more than 5%, according to a study published online July 21 in the Annals of Emergency Medicine.
Study: CT screening would cut lung cancer deaths in China July 25, 2017 -- Using a statistical model, Chinese researchers found that CT screening could reduce deaths from lung cancer in China by 24% compared with no screening, mostly by reducing deaths among smokers, according to a paper published July 14 in the Chinese Journal of Cancer.
WhatsApp works well for pediatric ortho trauma July 24, 2017 -- Researchers in Israel are finding new clinical uses for WhatsApp, the popular global text messaging platform. Reading images sent to smartphones via WhatsApp showed good agreement with the same images being read on a PACS workstation for pediatric orthopedic surgeons, according to a new study in Pediatric Emergency Care.
