Area of Science:

Medical Imaging
Artificial Intelligence
Computer Science

Background:

Advancements in computing and technology have enabled automation in healthcare.
Accurate brain tumor detection is crucial for effective patient treatment.

Purpose of the Study:

To develop an efficient deep-learning-based scheme for brain tumor (BT) detection.
To detect tumors in FLAIR and T2-modality magnetic resonance imaging (MRI) slices.
To verify the scheme's reliability using clinically collected and benchmark MRI slices.

Main Methods:

Pre-processing raw MRI images.
Deep-feature extraction using pretrained models.
Watershed-algorithm-based BT segmentation and shape feature mining.
Feature optimization using the elephant-herding algorithm (EHA).
Binary classification and verification using three-fold cross-validation.

Main Results:

The integrated feature-based scheme achieved a classification accuracy of 99.6667% with a support-vector-machine (SVM) classifier.
The scheme demonstrated reliable performance on both benchmark (BRATS, TCIA) and clinically collected MRI slices.
The proposed method showed improved classification results even when tested on noise-attacked MRI slices.

Conclusions:

The developed deep-learning scheme offers an efficient and accurate method for brain tumor detection in MRI.
The integration of deep features, shape features, and EHA optimization enhances classification performance.
The scheme's robustness against noise suggests its potential for real-world clinical applications.
