Glioblastoma is one of the leading types of brain cancer leading to patient death. To combat this type of cancer, many different types of imaging are used to analyze and treat glioblastomas. Still, magnetic resonance imaging, computed tomography, and positron emission tomography are the most commonly used imaging methods. In this literature review, the three different types of imaging are analyzed based on the preparation before imaging by the patient, the methods by which the images are created, the risks involved, and the technological advances in each category. The technological advances also included tools that combined two types of cancer imaging into one. The attributes of each imaging type are then analyzed to see which imaging methods are most effective and how they can be used to create better patient outcomes. Through this review, it was seen that all three methods of imaging were effective in their own ways, but the decision for which tool was based on what stage the cancer was in.
