Right heart quantification awareness: Part 6
January 16, 2018 -- In the sixth installment of this series, Judith Buckland from consulting firm CardioServ offers a quantitative method for performing right ventricular index of myocardial performance (RIMP), which can be used to evaluate right ventricular function with echocardiography.  Discuss
Artificial intelligence, brain MRI aid kids with hearing loss
January 15, 2018 -- U.S. and Chinese researchers have developed a machine-learning algorithm that analyzes MRI brain scans to predict how well deaf children may be able to develop language skills after receiving a cochlear implant, according to a study published online January 15 in the Proceedings of the National Academy of Sciences.  Discuss
3D power Doppler helps detect fetal growth restriction
January 15, 2018 -- 3D power Doppler can help confirm fetal growth restriction, a pathologic condition that occurs in up to 9% of pregnancies and can affect not only how a woman's pregnancy is followed but also when she delivers her baby, according to a study published in the January issue of the Journal of Ultrasound in Medicine.  Discuss
Philips to move North American HQ to Cambridge
January 12, 2018 -- Philips plans to move the headquarters of its Philips North America business to a new site being developed in Cambridge, MA, from its current location 25 miles away in Andover, MA.  Discuss
New PET radiotracer offers insight into multiple sclerosis
January 12, 2018 -- Combining PET scans with a novel radiotracer could help researchers track damage to myelin in the brain, providing insight into the treatment of multiple sclerosis as well as the development of other disorders, according to a preclinical study published online January 12 in Scientific Reports.  Discuss
3T MRI fetal scans should not affect newborns' hearing
January 12, 2018 -- When pregnant mothers are scanned with 3-tesla MRI, the higher noise levels relative to 1.5-tesla scanners do not seem to increase the risk that their babies will have hearing problems after birth, according to new research from Boston Children's Hospital and the Children's Hospital of Philadelphia.  Discuss
Should chest CT scans be reviewed for breast lesions?
January 12, 2018 -- What should be done with incidental breast lesions detected in women receiving chest CT exams? A new study recommends not only that these lesions be followed up, but also that a new reporting scale similar to BI-RADS be used to classify the findings, according to results published in Clinical Imaging.  Discuss
CMS to ease rules for MRI scans of implantable devices
January 11, 2018 -- Reimbursement could soon get a lot easier for MRI scans of patients with implantable cardiac devices. The U.S. Centers for Medicare and Medicaid Services (CMS) on January 11 proposed withdrawing its requirement that payments for these scans only be made when the scans are performed within a clinical study.  Discuss
CCTA predicts heart events in stable chest pain patients
January 11, 2018 -- By detecting high-risk plaque, coronary CT angiography (CCTA) can predict major adverse cardiovascular events in patients with stable chest pain, according to a January 10 study in JAMA Cardiology. But the jury is still out on whether CCTA findings should be added to risk stratification tools such as Framingham scores.  Discuss
Artificial intelligence guides lower PET tracer dose
January 11, 2018 -- In PET imaging, the amount of radiotracer dose correlates with the level of image quality. But what if artificial intelligence (AI) could enable PET to be performed using only 1% of current dose levels -- speeding exam times, decreasing radiation exposure, lowering costs, and alleviating shortages in radiotracers?  Discuss
