Analysis of Preoperative Diagnosis and Clinical Application Value of MSCT Enhanced Scan for Gastric Stromal Tumor

Objective To analyze the preoperative diagnosis and clinical application value of MSCT enhanced scan for gastric stromal tumor. Methods The clinical data of 40 patients with gast ric st romal tum o rs admitted to our hospital from January 2018 to March 2019 were ret rospectively analyzed.The imaging featu res of MSCT plain scan and enhanced scan were observed and compared with pathological diagnosis results.The MSCT cha racteristics of gastric stromal tumors were analyzed,and the relevant data after a plain scan and enhanced scan of the tumor were recorded.Results The accuracy of MSCT in the diagnosis of the benign and malignant gastric stromal tumors was 90.00%,and the accuracy in the diagnosis of malignant gastric stromal tumor was 92.86%,the accuracy in the diagnosis of the benign gastric stromal tumor was 85.71%.The diameter of the tumor was between 1.7 cm and 21.55 cm.There were 19 patients with a diameter of tumor greater than 5 cm,15 patients with diameter of5-15 cm,and 6 patients with a diameter of tumor less than 5 cm.When the tumor was small,the CT scan showed a round or round-like mass with uniform density and clear boundary.The enhanced scan showed significant uniform enhancement in the arterial phase and continuous enhancement in the nephrographic phase.When the tumor was large,the CT scan showed a lobulated and irregular mass,swelling or invasive growth,irregular contour of the gastral cavity,and uneven density,and showed necrosis of low density,cystic change and scattered calcification like a plaque.The enhanced solid part showed noticeable and continuous enhancement,and the enhancement of necrotic foci was not noticeable.Conclusion MSCT is of great value in the diagnosis and differential diagnosis of gastric stromal tumors.Combined with the clinical characteristics of patients is helpful for the qualitative diagnosis of gastric st romal tumor.
