This study evaluates the accuracy and speed of large language models (LLMs) in automatically vetting lumbar spine MRI referrals from general practice.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Three LLMs (GPT-4, Claude Opus, Gemini) were tasked with assigning an outcome (Accept \u2013 Routine, Accept \u2013 Urgent, Reject) and flagging MRI contraindications for lumbar spine referrals. Three prompts of increasing detail, including clinical guidelines and training examples, were used. Two radiology registrars synthesised 120 referrals, vetted by two board-certified radiologists, with a third resolving disagreements. Performance was assessed using accuracy, precision, recall and F1 scores.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Inter-rater agreement between radiologists was substantial for vetting outcome (Cohen's\n                      <jats:italic toggle=\"yes\">\u03ba<\/jats:italic>\n                      \u2009=\u20090.76) and contraindication detection (\n                      <jats:italic toggle=\"yes\">\u03ba<\/jats:italic>\n                      \u2009=\u20090.68). Claude Opus with the full prompt achieved the highest accuracy (0.86) for vetting outcomes. GPT-4 with the instruction-only prompt achieved the highest F1 score (0.88) for contraindication detection. LLMs completed the task substantially faster than radiologists (9.8\u2009\u00b1\u20091.0 vs 135.0\u2009\u00b1\u200945.0\u2005min).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>LLMs demonstrate promising performance in vetting radiological referrals for sciatica, particularly with detailed context.
