Early finding and analysis of brain tumor are essential to enhance the surgical planning and thus extend the survival of patients. Medical imaging techniques (MIT’s) are useful to view the internal structure of the brain which makes the medical professional to diagnose abnormal conditions and guide therapeutic procedures. Few MIT’s are handling in the medical industry to identify the brain tumor and each technique has different risks and benefits. The concerning techniques are single photon emission computed tomography (SPECT), computed tomography (CT), positron emission tomography (PET), magnetic resonance imaging (MRI), functional MRI (fMRI), and blood oxygen level dependent (BOLD). This paper presents the importance of MIT’s in brain tumor treatment.
