Machine learning approach detects brain tumor boundaries

Glioblastoma is an aggressive and hard-to-treat type of brain cancer. But because it affects fewer than 10 in 100,000 people each year, it's considered to be a rare disease. Defining the boundaries of glioblastoma tumors is important for treatment. One key region represents the breakdown of the blood-brain barrier inside the tumor. Another, called the tumor core, could be relevant for surgical removal.
