Value of 3.0 T Pelvic MRI Combined with Enhanced CT Imaging in the Differential Diagnosis of Colorectal Tumors
Objective To explore the application value of 3.0 T pelvic magnetic resonance imaging(MRI)combined with dual energy CT imaging in the diagnosis of colorectal tumors,in order to provide a basis for clinical intervention measures.Methods A total of 138 patients with colorectal tumors diagnosed in Jiaozuo People's Hospital from April 2022 to August 2023 were retrospectively analyzed,and all of them underwent 3.0 T pelvic MRI and enhanced CT imaging after admission,and the results of pathological examination were used as the gold standard to compare the diagnostic results and diagnostic efficacy of 3.0 T pelvic MRI and enhanced CT imaging on colorectal tumors individually and jointly.The diagnostic results of 3.0 T pelvic MRI and enhanced CT imaging on colorectal tumors individually and in combination with each other were compared,and the consistency between the diagnostic results of clinical staging and pathological examination results was analyzed.Results Among 138 patients with colorectal tumors,72 cases were positive by pathological examination,60 cases were positive by 3.0 T pelvic MRI examination,58 cases were positive by dual energy CT imaging,and 71 cases were positive by combined diagnosis.The combined examination of 3.0 T pelvic MRI and dual energy CT imaging had a sensitivity of 94.44％and an accuracy of 94.93％for the diagnosis of colorectal tumors,which were higher than that of 3.0 T pelvic MRI alone(sensitivity of 80.56％and accuracy of 88.41％)and dual energy CT imaging(sensitivity of 76.39％and accuracy of 85.51％),the missed diagnosis rate was 5.56％,which was lower than the missed diagnosis rate of 19.44％on 3.0 T pelvic MRI alone and 23.61％on dual energy CT imaging(P＜0.05).The consistency between clinical staging and pathological results of 3.0 T pelvic MRI,dual energy CT imaging,and combined diagnosis of colorectal tumors was 0.818,0.772 and 0.923,respectively(P＜0.05).Conclusion 3.0 T pelvic MRI combined with dual energy CT imaging can be used in the diagnosis of colorectal tumors,providing a plan for early clinical differential diagnosis and evaluation of clinical staging,in order to develop follow-up treatment measures and improve prognosis.
