This study developed an automatic blood vessel detection method for breast MRI using a Hessian-based algorithm. The new method significantly reduces false positives in computer-aided diagnosis (CAD) systems, improving diagnostic accuracy.

Area of Science:

  • Medical Imaging
  • Radiology
  • Computer-Aided Diagnosis

Background:

  • Accurate detection of blood vessels in breast MRI is crucial for differentiating lesions.
  • Computer-aided diagnosis (CAD) systems can be hindered by misclassification of vascular structures as lesions.

Purpose of the Study:

  • To develop an automated, multiscale, 3D Hessian-based algorithm for blood vessel detection in dynamic contrast-enhanced (DCE) breast MRI.
  • To assess the algorithm's efficacy in reducing false positives generated by CAD systems due to misclassified vessels.

Main Methods:

  • A 3D Hessian-based algorithm was employed for linear structure detection, followed by morphological analysis to exclude non-vascular enhancements.
  • The algorithm was tested on 28 DCE-MRI examinations across two centers, using diverse imaging parameters and contrast agents.

  • Performance was evaluated by comparing automated vessel detection against manual tracking by an expert radiologist.

    • Main Results:

    • The algorithm achieved a median correct-detection rate of 89.1% and a missed-detection rate of 10.9%.
    • Vessel exclusion by the algorithm reduced false positives in the CAD system by a median of 68.4%.
    • No significant differences in performance were observed between imaging groups (P > 0.25).

    Conclusions:

    • The developed algorithm effectively detects breast blood vessels in DCE-MRI across various imaging conditions.
    • This automated method shows potential to improve CAD specificity by reducing vessel-related false positives, thereby supporting clinical workflow integration.
