RSNA Announces Cervical Spine AI Challenge Results

Conducted by the Radiological Society of North America (RSNA), in collaboration with the American Society of Neuroradiology (ASNR) and the American Society of Spine Radiology (ASSR), the RSNA Cervical Spine Fracture AI Challenge results will be recognized in a presentation on Monday, Nov. 28, in the AI Showcase during the annual meeting.

The top eight teams in the RSNA Cervical Spine Fracture AI Challenge are:

  1. Qishen Ha
  2. RAWE
  3. Darragh
  4. Selim Seferbekov
  5. Speedrun
  6. Skecherz
  7. qwer
  8. Harshit Sheoran

The aim of the challenge was to explore whether artificial intelligence (AI) could be used to aid in the detection and localization of cervical spine injuries. The international imaging dataset compiled and curated for the challenge is one of the largest and most diverse of its kind, including detailed clinical labels, radiologist annotations and segmentations.

"A unique aspect of this year's RSNA AI Challenge is the great diversity of data," said Errol Colak, MD, FRCPC, assistant professor in the Department of Medical Imaging at University of Toronto in Ontario, Canada.

To create the ground truth dataset, the challenge planning task force collected imaging data sourced from 12 sites on six continents, including more than 1,400 CT exams with diagnosed cervical spine fractures, and a roughly equal number of negative exams. To aid researchers in training their detection algorithms, spine radiology specialists from the ASNR and ASSR provided expert image level annotations to a subset of these images to indicate the presence, vertebral level and location of any cervical spine fractures.

For the challenge competition, contestants attempted to develop machine learning models that matched the radiologists' performance in detecting and localizing fractures within the seven vertebrae that comprise the cervical spine.

"The machine learning models that were developed as part of this challenge may help advance patient care by assisting radiologists and other physicians in detecting fractures, which can be a difficult task," Dr Colak said. "These models may be of particular value in underserviced areas with limited access to expert neuroradiologists. Furthermore, these models can help patient care by prioritizing positive CT scans for radiologist review in high volume clinical settings."

The RSNA Cervical Spine Fracture AI Challenge was conducted on a platform provided by Kaggle, Inc. The top performing competitors will be awarded a total of $30,000.
