Osborn ASNR International Outreach Professor Program award to represent the American Society of Neuroradiology.

Research Projects

  1. Development and validation of a Fast Spine Protocol for Use in Paediatric Patients


    This study demonstrates that selected spinal imaging sequences allows for consistent and accurate diagnosis of specific clinical conditions. A limited spine protocol reduces acquisition time, potentially avoiding sedation. Further work is needed to determine the utility of selected imaging for other clinical indications.

  2. Risk of Hypothyroidism After Administration of Iodinated Contrast Material in Neonates: Are You Aware?


  3. Whole-Body Diffusion-Weighted MRI Compared to 18 FFDG PET/CT in Initial Staging and Therapy Response Assessment of Hodgkin Lymphoma in Pediatric Patients


    There was poor correlation between the ADC ratios and the absolute change in SUV between baseline and follow-up (0.348).

  4. 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.

  5. 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.
