Area of Science:

  • Medical Imaging
  • Artificial Intelligence
  • Oncology

Background:

  • Manual detection of brain metastases (BMs) is a time-intensive process.
  • Deep learning (DL) offers a potential solution for automating BM detection.

Purpose of the Study:

  • To systematically review and meta-analyze the performance of DL models using MRI for detecting BMs in cancer patients.
  • To assess the diagnostic accuracy and detectability of DL algorithms in identifying BMs.

Main Methods:

  • Systematic literature search of MEDLINE, EMBASE, and Web of Science until September 2022.
  • Inclusion of original research articles using DL with MRI for BM detection, excluding reviews and machine learning studies.
  • Quality assessment using QUADAS-2 and CAAI methods, with 24 studies included in quantitative analysis.

Main Results:

  • The pooled patient-wise and lesion-wise detectability of BMs using DL models was 89%.
  • Deep learning algorithms demonstrate significant effectiveness in detecting BMs.
  • Pooled analysis of false positive rates was not feasible due to inconsistent reporting across studies.

Conclusions:

  • Deep learning models are effective tools for detecting brain metastases using MRI.
  • Improved adherence to reporting checklists is recommended for future AI in medical imaging studies.
  • Further standardization is needed to enable robust analysis of false positive rates.
