Dr. Elka Miller is an Associate Professor of Radiology at the University of Ottawa and a staff pediatric neuroradiologist at CHEO since 2009.
Dr. Miller is the Chief and Research Director of the Medical Imaging Department at CHEO. She advocates for deliver quality specialized pediatric radiology services to the children in the region.
Dr. Miller is actively involved in research and medical education with a special interest in Pediatric Neuroimaging, Fetal and Neonatal Imaging. She is a reviewer for multiple international journals, and has been six times recipient of the Editor Recognition Award for reviewing with distinction from the Radiology Journal. She received the RSNA Roentgen Resident/Fellow Research Award in 2008. Recently, Dr. Miller received the 2018 Anne G. Osborn ASNR International Outreach Professor Program award to represent the American Society of Neuroradiology.
Comparison of the diagnostic performance of the 2017 ACR TI-RADS guideline to the Kwak guideline in children with thyroid nodules
Both the Kwak-TI-RADS and ACR TI-RADS guidelines provide moderate malignancy risk stratification for thyroid nodules in the pediatric population, with better inter-rater agreement for the ACR TI-RADS guideline. Further work to adjust the recommendations for pediatric patients is necessary.
MRI features of the placenta in fetuses with and without CNS abnormalities
The presence of fetal CNS abnormalities is associated with reduced ADC values of the placenta. Moreover, placentas of fetuses with CNS abnormalities show a less rapid increase in fetal to placental volume ratio with GA. Therefore, ADC mapping, as well as different growth kinetics of the placenta relative to the fetus, may potentially serve as early markers of pathological neurodevelopment.
Apparent Diffusion Coefficient of the Placenta in Twin versus Singleton Pregnancies
The diffusion characteristics of twin placentas are similar to those of singleton placentas. ADC and rADC remain stable throughout pregnancy in twin and singleton placentas, reflecting stable extracellular water diffusion, despite changes associated with placental maturation.
Does 3T Fetal MRI Improve Image Resolution of Normal Brain Structures between 20 and 24 Weeks’ Gestational Age?
Both magnets depict cerebral and facial normal anatomic structures; however, our data indicates better anatomic detail on the 3T than on the 1.5T magnet.
