Abstract

Value of MRI diffusion‑weighted imaging (MRI DWI) combined with PET/CT in the diagnosis and staging of stomach cancer (SC) was investigated. A retrospective analysis was performed on 160 patients with SC diagnosed by pathological biopsy in The Affiliated Yantai Yuhuangding Hospital of Qingdao University from March 2015 to April 2018. The values of MRI DWI, PET/CT and combined diagnosis in the diagnosis and staging of SC were compared according to the criteria of diagnosis of postoperative pathological or clinical comprehensive evaluation. The sensitivity, specificity and diagnostic coincidence rate of MRI DWI in the diagnosis of SC at stage I-II were 61.05, 64.62 and 62.50%, respectively, which were significantly lower than those of PET/CT (P<0.05). Sensitivity, specificity and diagnostic coincidence rate of MRI DWI in the diagnosis of SC at stage III-IV were lower than those of PET/CT (P<0.05). Sensitivity and diagnostic coincidence rate of MRI DWI combined with PET/CT in the diagnosis of SC at stage I-II were significantly higher than those of MRI DWI or PET/CT alone (P<0.05). Specificity and diagnostic coincidence rate of MRI DWI combined with PET/CT in the diagnosis of SC at stage III-IV were significantly higher than those of MRI DWI or PET/CT alone (P<0.05). PET/CT is superior to MRI DWI in SC staging, whereas the diagnostic efficiency of combined scan is much higher than that of PET/CT or MRI DWI alone. In order to obtain more accurate preoperative staging and to avoid diagnostic exploratory laparotomy, the combination of MRI DWI and PET/CT techniques should be used in the comprehensive analysis of the disease to improve the accuracy of clinical diagnosis.
