ABSTRACT: Cancer is a disease that human being has been suffering from it for a long time. Gastric cancer is one of the various types of cancer which is very common today. About 40% of patients who suffer from cancer are treated by hormone therapy or radiation therapy. In this method cancer cells are destroyed using methods PET.CT or MRI imaging scans. The process is done using two methods of external radiation therapy and internal radiation therapy. In cancer treatment by these methods, the ultimate goal is to deliver maximum dose to cancerous tissue with minimal side effects on healthy tissue around the tumor. Advances in technology have helped that the field of rays be limited to the treatment area as far as possible and thereby the healthy tissues are largely protected. The use of MRI in medicine, particularly in the field of cancer diagnosis and treatment has attracted many researchers over the past two decades and is still being used to reduce the damages and to prevent the spread of disease symptoms (such as pain). These devices are essentially used to identify and locate the related tumor and the tissue receives different types of rays, the most common of which include the computed tomography (CT), magnetic resonance imaging (MRI) and recently introduced positron emission tomography (PET). After identifying the desired tissue location, the simulation should be started which is planned based on the anatomy of the patient. This paper tries to compare PET.CT and MRI imaging scans detection methods for the diagnosis of gastric cancer.
