AI Progress in Brain Metastases Detection and Treatment

Published Date : 6/9/2025 

This review explores the integration of AI, particularly machine learning and deep learning, in the detection, segmentation, and prognosis of brain metastases. The article highlights the potential of AI to enhance diagnostic accuracy and support personalized treatment plans. 

As artificial intelligence (AI) continues to evolve, its integration into medical practice is becoming increasingly prominent, particularly in the field of neuro-oncology. This review examines the application of AI—specifically machine learning (ML) and deep learning (DL)—in the imaging evaluation of brain metastases (BM). A systematic search of PubMed was conducted to identify relevant studies published within the past five years. The retrieved literature was categorized and analyzed according to three key clinical tasks: segmentation, differential diagnosis, and prognostic prediction.

We first outline the capabilities of AI in the automatic detection and segmentation of BM using advanced imaging techniques. AI algorithms, particularly deep learning models, have shown remarkable accuracy in identifying and delineating brain metastases from medical images such as MRI and CT scans. These models can process large volumes of data quickly, enhancing the efficiency and consistency of the diagnostic process.

Subsequently, we synthesize evidence on how AI aids in distinguishing BM from other intracranial structures and lesions. One of the significant challenges in neuro-oncology is differentiating brain metastases from other conditions like gliomas or abscesses. AI tools, trained on extensive datasets, can help clinicians make more accurate differential diagnoses, reducing the risk of misdiagnosis and improving patient outcomes.

Finally, we discuss the emerging role of AI in predicting disease prognosis and the development of new metastatic abnormalities. By analyzing imaging data alongside clinical and genetic information, AI models can provide valuable insights into the progression of brain metastases. This information can be crucial for developing personalized treatment plans and improving patient survival rates.

Current evidence suggests that AI not only enhances diagnostic efficiency and reproducibility but also provides clinically meaningful insights that support personalized treatment planning. Importantly, the integration of AI into neuro-oncological imaging remains at a nascent stage, indicating substantial potential for future growth and refinement in both technical performance and clinical applicability.

The Shandong First Medical University and Shandong Provincial Hospital are at the forefront of this research, contributing significantly to the development and validation of AI algorithms in neuro-oncology. Their work highlights the importance of interdisciplinary collaboration between medical professionals and data scientists to advance the field of AI in healthcare.

In conclusion, the integration of AI into the imaging evaluation of brain metastases offers promising opportunities to improve diagnostic accuracy, enhance treatment planning, and ultimately, improve patient outcomes. As AI continues to evolve, it is essential to address challenges such as data privacy, algorithm transparency, and clinical validation to fully realize its potential in neuro-oncology.
