Role of molecular imaging in prognosis, diagnosis, and treatment of gastrointestinal cancers: An update on new therapeutic methods

Figure 5 Role of personalized medicine and molecular imaging in pancreatic cancers. The function and role of molecular imaging and personal medicine in the management of pancreas is shown in a semantic way, and the possibility of playing the role of these two concepts does not have any special priority or delay, and it can be both concurrent and concurrent, and it is changing day by day. The role of these two concepts is to adopt the most accurate, appropriate and personalized mode possible for pancreatic cancer patients from the initial stages of collecting individual demographic information of patients, collecting human samples including blood, urine and biopsy samples, etc. and checking and their analysis, in the path of individualization using the common methods of novel imaging and anatomical laboratory and even at the cellular and molecular level to determine the most appropriate and targeted treatment including various medical methods (drugs, type and amount) and various surgical methods, radiation Treatment or combined methods is to determine the rate of response to treatment, recurrence, prognosis and follow-up of patients according to the conditions and characteristics of each patient. Imaging modality in determining the course of diagnosis and determining prognosis includes endoscopy, computed tomography (CT), positron emission tomography (PET) and their combination with chemical agents such as 68Ga- fibroblast activation protein inhibitor (FAPI) PET/CT, 18F-fluorodeoxyglucose (FDG) PET/CT and even FAPI PET/CT alone, and Gd-enhanced magnetic resonance imaging (MRI) with diffusion-weighted along contrast-enhanced CT and adopting a treatment plan based on CT, PET, PET/CT, 18F-FDG PET/CT, FDG-PET/contrast-enhanced CT, FDG-PET/non-contrast-enhanced CT, FAPI PET/CT, single-photon emission CT/CT and dynamic contrast-enhanced-MRI are utilized to select chemotherapy, endohistochemical therapy or medical treatment based on personalized medicine.
