Brief Biography

Dr. Andrea Doria received her medical degree from the Universidade Federal do Parana, Brazil, and did her training in Paediatrics and Radiology at the Universidade de Sao Paulo, Brazil. She then received a PhD in medical sciences from the Universidade de Sao Paulo, Brazil. She moved to Canada to pursue a fellowship in Pediatric Radiology and obtained a master’s degree in clinical epidemiology at the University of Toronto. During her fellowship she received the 2002 John Caffey Award for her work on BOLD MRI in experimental arthritis and the 2003 John Kirkpatrick Young Investigator Award for her meta-analysis in appendicitis.  Her passions are: the implementation of innovative analytic methods, processes and strategies that can improve clinical practice, development of evidence-based best practice guidelines that can lead to excellence of patient care, and translation of science and technologies into practices that can transform healthcare delivery. Her teaching interests include the delivery of a course on “Introduction to Research for Radiologists” with the goal of improving the quality of research in radiology.

Research Interests

  • Musculoskeletal imaging (focus: cancer and arthritis): Translation of innovative experimental MRI and ultrasound research methods into clinical practice
  • Radiogenomics: Development of novel integrative clinical-imaging-biochemical paradigms of patients’ outcomes.
  • Data analytics, Artificial Intelligence: Use of machine learning tools to optimize classification of findings, augmentation of data and prediction of disease progression.
  • Technology, Processes and Operations’ Innovation: Using technology for prioritization of activities, forecast of flow of patients throughout the organization and effectiveness maximization at minimum costs and at optimal patients’ satisfaction.

Ongoing Projects/Initiatives

  • Use of novel MRI and ultrasound techniques to investigate potential imaging markers that test measurement properties (reliability, validity, responsiveness, sensitivity, specificity). These properties provide a means to track angiogenesis-related factors (cause) and early cartilage degeneration (effect) in musculoskeletal disorders in kids. 
  • Develops and tests scales for measurement of osteoarticular changes in children both at national and international (collaborative research) levels.
  • Research program translates innovative experimental and novel MRI and ultrasound techniques into human clinical research.

1. Radiogenomics: Personalized Imaging of Arthropathy in Boys with Hemophilia in China (PI: funded by Shire-Baxter BioScience Grant, 2018-2021): By correlating clinical, conventional imaging and novel imaging joint features that lead to unfavourable outcomes we should be able to categorize patients with specific phenotypes into “risk groups” for joint degeneration.

2. Novel Approaches to Molecular and Clinical Surveillance in Li-Fraumeni Syndrome (PI – Project 4: funded by the Terry-Fox Foundation, 2018-2023): Using three novel MRI techniques (whole body inversion recovery MRI, whole body diffusion-weighted MRI and FGD PET-MRI) to determine how sensitive they are at detecting diminutive tumors, and to apply genetic determinants of cancer risk to surveillance and prevention.

3. Imaging of Hypoxia in Childhood Sarcomas: Feasibility Steps Towards Personalized Medicine (PI: funded by the Society of Pediatric Radiology and Garron Family Cancer Centre): Determining the feasibility of using novel/existing imaging technologies focused on hypoxia measurements (BOLD, DWI, MRS, 18F-FAZA PET-MRI) to determine “response to therapy” in pediatric sarcomas.

4. Can Ultrasound “See” What Clinicians Cannot in Hemophilic Arthropathy? Point-of-Care Ultrasound and Physical Examination Perspectives (PI: Access to Insight Clinical Research Grant (Novo Nordisk): Implementing the use of point-of-care ultrasound (POCUS) as an “added value tool” for assessment of joints of patients with hemophilia  in clinical practice by creating an algorithm for diagnostic management of patients based on effective outcomes
according to different clinical situations.

5. Developing and Validating MRI Scales as Outcome Measures in Juvenile Idiopathic Arthritis (JIA): Investigating measurement properties (reliability, validity, responsiveness, sensitivity, specificity) of MRI scales in JIA: Collaborative work through the Pediatric OMERACT group.

6. Testing and Implementing the Use of MRI for Diagnostic of Pediatric Appendicitis (PI: funded by the Physicians’ Incorporation Foundation, 2016-2018): Using an ultrafast 3-Tesla MRI, with excellent patient acceptance, no need for sedation, high sensitivity/specificity, without bearing ionizing radiation. Collaborative work among emergency physicians, emergency room nurses, radiology technologists, radiologists, surgeons, fellows, residents and transportation volunteers.

7. Implementing the Efficiency of a Tertiary Hospital MRI Service: Developing strategies to maximize efficiency of the MRI system by minimizing delays throughout the pipeline of functions of the system, while maintaining high imaging and patient service quality.Future Research 

Her past research contributed to:

(i) Knowledge/Research Advancement: Improved understanding on the biologic rationale for hypoxia in inflamed joints (BOLD MRI) which was translated from animals to humans; proved the feasibility of using novel imaging techniques for quantification of joint bioproducts of arthritis in animals (USPIO; T2 mapping;FDG-PET; dynamic MRI, contrast-enhanced ultrasound [US]) and humans (ultra-short TE; 3DUS and fusion US-MRI).
(ii) Health Care/Outcomes: Recommended approaches for US/MRI data acquisition in childhood arthritis led to the development of US/MRI scales and atlases, which were applied and validated in international research, thus pioneering improvement of diagnosis and follow-up of children with arthritis;
(iii) Health Systems: Led evidence-based knowledge syntheses on diagnostic accuracy of US/MRI for assessment of JIA, hemophilia, osteoporosis, hip dysplasia and appendicitis and participated in the development of evidence-informed policies/guidelines in the field.
(iv) Knowledge Translation: Enabled global dissemination of information on imaging scoring systems and protocols to scientific and patients’ communities through international collaborations with India, Brazil, China, Sweden, Canada, U.S.A. (in hemophilia), and Netherlands, Germany, Switzerland, Norway, Spain, Canada, U.S.A. (in juvenile idiopathic arthritis).
