Positron emission tomography (PET) scanners have significantly contributed to the advancement of Nuclear Medicine. The integration of PET scanners with computed tomography (CT) and magnetic resonance imaging (MRI) has led to the development of PET/BT and PET/MRI systems, enabling the acquisition of both functional and anatomical information within the same image. The higher soft tissue contrast resolution of MRI compared to CT has improved diagnostic image quality. Additionally, since MRI does not involve ionizing radiation, the radiation dose administered to patients has been reduced. Furthermore, the integrated nature of PET/MRI systems allows for the simultaneous acquisition of axial, coronal, and sagittal sectional images. The dijital nature of the PET module has resulted in higher sensitivity, thereby reducing the amount of radiopharmaceuticals administered to the patient by approximately 50%. However, the longer MRI scanning time compared to CT decreases patient throughput. Moreover, the high cost of PET/MRI systems poses a significant barrier to their widespread adoption.
