RSNA Committee on International Radiology Education: 25 Years of Global Education Outreach.

The Radiological Society of North America (RSNA) Committee on International Radiology Education (CIRE) has worked for the past 25 years to create academic programs oriented to the needs of international radiologists. The CIRE develops organized and structured approaches to help build one's capabilities and increase one's capacity for professional growth, which then facilitates better patient care. The authors describe the four programs that CIRE is responsible for and introduces its newest initiative, Global Learning Centers, which is planned to start in 2021. RSNA involvement in global radiology education provides opportunities for early, mid-, and late-career radiologists to participate in these programs as students or teachers. The authors describe some of the programs' success stories and invite readers to become a part of and contribute to the growth of radiologic academic endeavors globally. ©RSNA, 2020.

Anatomical variations of the ethmoidal roof: differences between men and women.

AIM: During the paranasal sinuses surgery different complications may occur, both vascular and bony. The objective of the present study was to evaluate the ethmoidal roof configuration through the Keros and Yenigun classifications, analyzing results stratified by gender and side. MATERIALS AND METHODS: We retrospectively analyzed 120 high-resolution computed tomography paranasal sinus study images and measured the depth of the cribriform plate in a coronal view and the anterior-posterior length in a cross section. RESULTS: The Keros Type II was the most frequent and no statistically significant difference was found when comparing by gender. Yenigun type I was more prevalent, and a statistically significant difference was found between men and women in types I and II (p = 0.010 and p = 0.049, respectively). Statistical difference was observed in anterior-posterior means in the comparison between both classifications. In both, right and left side for men (p = 0.003 and p = 0.05) and women (p = 0.029 and p = 0.039). CONCLUSION: We demonstrate the morphological variability that exists in this region. Gender differences that must be considered by the surgeon to avoid complications. Further studies are needed to evaluate the value of these findings when predicting surgical complications. A CT before PNS surgery is already widely accepted.
