Brain Imaging

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic...

Magnetic Resonance Imaging

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Area of Science:

Medical Imaging
Artificial Intelligence
Machine Learning

Background:

Brain tumors are aggressive, necessitating early diagnosis for effective treatment and improved patient quality of life.
Manual interpretation of Magnetic Resonance Imaging (MRI) for brain tumor diagnosis is time-consuming and error-prone.
Automated methods are crucial for efficient and accurate brain tumor identification.

Purpose of the Study:

To develop an efficient hyperparameter optimization technique for Convolutional Neural Networks (CNNs) using Bayesian Optimization for brain tumor classification.
To automate the identification of common brain tumors from CE-MRI images.

Main Methods:

Proposed a Bayesian Optimization-based hyperparameter tuning method for CNNs.
Evaluated the model on 3064 T-1-weighted CE-MRI images, classifying Glioma, Meningioma, and Pituitary tumors.
Compared the optimized CNN performance against five pre-trained deep learning models using Transfer Learning.

Main Results:

The optimized CNN achieved a maximum validation accuracy of 98.70% without data augmentation or cropping.
Pre-trained models achieved lower accuracies: VGG16 (97.08%), VGG19 (96.43%), ResNet50 (89.29%), InceptionV3 (92.86%), and DenseNet201 (94.81%).
The proposed model demonstrated superior performance compared to state-of-the-art methods on the CE-MRI dataset.

Conclusions:

Bayesian Optimization is an effective technique for automating CNN hyperparameter tuning in medical image analysis.
The developed method offers a feasible and highly accurate approach for automated brain tumor classification.
This AI-driven strategy enhances diagnostic efficiency and accuracy for critical diseases like brain tumors.
