Diagnostic Neuroradiology Subspecialty Training: 1 Versus 2 Years; the Canadian Perspective.

BACKGROUND: Canada began a national reform of its post-graduate medical education training programs to a Competence By Design (CBD) model. Trends from accredited neuroradiology programs from the past 10 years were investigated to inform educators and stakeholders for this process. METHODS: A 13-question electronic survey was sent to program directors of all 8 accredited neuroradiology training programs in Canada. Data was requested for each year on the 2008-2019 graduating classes. Questions pertained to program enrolment; program completion; post-training employment; and the sufficiency of 1-year training programs. RESULTS: Response rate was 100%. Over the timeframe studied, the 2-year programs increased in size (P = 0.007), while the 1-year programs remained steady (P = 0.27). 12.2% of trainees enrolled in the 2-year program dropped out after 1 year, and were considered 1-year trainees thereafter. A higher proportion of 2-year trainees obtain positions within academic institutions (89.5 vs 67.2%, P = 0.0007), whereas a higher proportion of 1-year trainees obtain positions within non-academic institutions (29.3 vs 8.1%, P = 0.0007). A higher proportion of those with Canadian board certification in diagnostic radiology who completed a 2-year program obtained a position within a Canadian academic institution compared to non-certified 2-year trainees (P < 0.001). 71.4% of program directors agreed that a 1-year program was sufficient for non-academic staff positions. CONCLUSION: The length of the training program has significant impact on employment in academic vs non-academic institutions. This information can be used to guide the upcoming CBD initiative for neuroradiology programs.

Imagen por resonancia magnética en tumores de la fosa posterior / MRI in posterior fossa tumors

Los tumores de la fosa posterior en niños son lamentablemente frecuentes, siguiendo solamente a las leucemias en la población pediátrica. La presentación con náuseas y vómotos a menudo simula una enfermedad del aparato digestivo y demora la investigación neurológica. En los últimos años, con la llegada de la resonancia magnética como medio de diagnóstico, la investigación de estas entidades se ha facilitado, puesto que de una manera no invasiva, sin mayores molestias para el paciente y sin riesgo conocido, se puede establecer no solamente un diagnóstico preciso, sino también se establece la localización exacta para el manejo quirúrgico y/o radioterapéutico. Hemos revisado 30 niños con tumores de la fosa posterior, en nuestra unidad de resonancia magnética, y una recopilación de la literatura reciente informando las características de estos tumores.
