Key Points

  • The paper presents a state-of-the-art method for early brain tumor identification using 3D medical image segmentation focused on benign vs. malignant tumors.
  • It builds on the SegResNet 3D segmentation architecture and trains the model with an automatic multi-precision training approach.
  • Model performance is evaluated using Dice loss and Dice metric, reporting an overall Dice score of 0.84.
  • The results break down into tumor core (0.84), whole tumor (0.90), and enhancing tumor (0.79) Dice scores, indicating stronger performance for whole-tumor delineation.
  • The approach targets practical, accurate 3D segmentation to support survival-critical early detection workflows in clinical contexts.

Abstract

A brain tumor is a medical disorder faced by individuals of all demographics. Medically, it is described as the spread of non-essential cells close to or throughout the brain. Symptoms of this ailment include headaches, seizures, and sensory changes. This research explores two main categories of brain tumors: benign and malignant. Benign spreads steadily, and malignant expresses growth, making it dangerous. Early identification of brain tumors is a crucial factor for the survival of patients. This research provides a state-of-the-art approach to the early identification of tumors within the brain. We implemented the SegResNet architecture, a widely adopted architecture for three-dimensional segmentation, and trained it using the automatic multi-precision method. We incorporated the dice loss function and dice metric for evaluating the model. We got a dice score of 0.84. For the tumor core, we got a dice score of 0.84; for the whole tumor, 0.90; and for the enhanced tumor, we got a score of 0.79.
