21st Century Innovations in Neuroradiology Treatments

Rapid technological progress in the 21st century has transformed neuroradiology from primarily a diagnostic tool into a vital component of modern neuroscience. This abstract summarizes innovations that have marked a paradigm shift in neurological and neurosurgical patient care. From symptom onset through hospitalization and recovery, these advancements have introduced novel techniques and redefined existing models to improve short-term and long-term outcomes.Artificial intelligence (AI) integration has significant implications in stroke triage, brain tumor segmentation, and treatment planning. Wearable AI-enabled devices detect abnormal changes in movement and speech, prompting patients to seek care immediately to ensure they remain within the therapeutic window for reperfusion therapy. AI models can also identify tumors that may be undetectable to the naked eye and provide precise lesion margins, reducing overestimation and underestimation during surgical planning. Image-guided minimally invasive procedures have reduced reliance on open surgery while increasing precision, minimizing perioperative risk, shortening postoperative hospital stays, improving functional outcomes, and lowering recurrence rates. Refinements in stent and catheter technology have further enhanced the safety and efficiency of these procedures in treating neurological disorders. Advanced imaging enables neurosurgeons to target surgically inaccessible lesions while preserving surrounding tissue and to analyze tumor behavior to objectively predict treatment response. Innovations in neuroradiology address disparities in access to care, as minimally invasive approaches offer therapeutic options for patients ineligible for open surgery, and remote interventions aim to expand timely access to specialized treatment in underserved regions. Continued advancements in neuroradiology will further optimize interventions, enhancing patient care.
