MI at the RSNA 2024 Annual Meeting

At the beginning of December, the Radiological Society of North America (RSNA) held its Annual Meeting in Chicago, which featured an impressive turnout from the Department of Medical Imaging, with several faculty and trainees presenting work, delivering lectures and winning awards.

Abstracts, Scientific Posters & Educational Exhibits
Dr. Kay Wu, PGY2 Diagnostic Radiology Resident, presented her abstract titled, “DeepSPINE: A Comprehensive Deep Learning Model for Multi-Task Lumbar Spine MRI Analysis,” which aimed to extend upon a deep learning model tailored for comprehensive, automated analysis of lumbar spine MRI to detect and grade nine degenerative spinal conditions. See Dr. Wu’s abstract here.

Dr. Jesús Arenós, Pediatric General Radiology Fellow at The Hospital for Sick Children, presented his abstract titled, “Imaging of myxoid-containing tumors in children and adolescents,” (Magdalena P. Reyes, MD, AndréaS. Doria, MD, PhD, MSc, MBA, Oscar M. Navarro, MD), of which he was the lead author. In his abstract, Dr. Arenós aimed to list pediatric myxoid-containing tumours, discuss different imaging modalities used and recognize the characteristic MRI signal of the myxoid matrix to facilitate the differential diagnosis of soft tissue tumors. See Dr. Arenós’ abstract here.

MI professor Dr. Masoom Haider co-authored a poster that was presented at the meeting, titled “AI Detects Missed Small Renal Masses on Single Phase CT,” along with Associate Professor Dr. Satheesh Krishna. The purpose of the study was to evaluate the performance of a UNet-based lesion segmentation model on SRMs missed by radiologists. See the poster here.
