[Abstract] Objective To analyze the application value of 128-slice spiral CT and multi-planar (MPR) post-processing technology in preoperative diagnosis of gastrointestinal stromal tumor (GIST), so as to valuable reference for clinical diagnosis in the future. Methods From January 2017 to June 2019, 20 GIST patients confirmed by surgical pathology and immunohistochemistry were selected as the research objects. A total of 128 slice spiral CT was performed on them, and MPR post-processing technology was applied. Based on the results of pathology and immunohistochemistry, the detection of lesions, the location and qualitative results of CT and MPR post-processing technology were statistically analyzed. Results By CT and MPR post-processing technology, 13 cases of gist were located in stomach, 5 in small intestine and 2 in duodenum. There were 13 cases of mucosal appearance and 7 cases of obvious ulcer in mucosa. There were 15 cases of solid capsule and 5 cases of solidity. Enhanced scanning revealed 12 cases of uniform tumor enhancement and 8 cases of uneven enhancement. Among the patients with uniform enhancement, 11 cases were diagnosed as benign and 1 case was potentially malignant. Among the patients with uneven enhancement, the lesions were diagnosed as benign in 2 cases and malignant in 6 cases. There were no significant differences between the location and qualitative results of CT and MPR post-processing technology and pathological examination (P>0.05). Conclusion 128-slice spiral CT and MPR post-processing technology can obtain accurate localization and qualitative results, and have high clinical diagnostic accuracy, which is worthy of attention and promotion.
CT檢查為目前GIST的主要檢查手段,其不僅可以對(duì)病灶形態(tài)、內(nèi)部結(jié)構(gòu)進(jìn)行顯示,并且能夠觀察包塊與周邊組織器官的毗鄰關(guān)系,依據(jù)影像特征對(duì)病變性質(zhì)進(jìn)行判斷,對(duì)術(shù)前治療方案選擇、術(shù)后監(jiān)測(cè)等均具有重要作用[10-11]。經(jīng)實(shí)踐證實(shí),在影像學(xué)診斷過(guò)程中,多層螺旋CT具有掃描時(shí)間短、定位準(zhǔn)確、掃描速度快等優(yōu)勢(shì),能夠?qū)δ[瘤血供嗆咳、腫瘤供血血管進(jìn)行動(dòng)態(tài)觀察,可為臨床診斷提供重要的參考信息[12-13]。
本研究選取我院收治的20例GIST患者作為研究對(duì)象進(jìn)行回顧性分析,結(jié)果顯示,CT檢查及MPR后處理技術(shù)的定位及定性結(jié)果與病理檢查結(jié)果比較,差異無(wú)統(tǒng)計(jì)學(xué)意義(P>0.05)。提示采用128層螺旋CT檢查及MRP后處理技術(shù)可取得高質(zhì)量的圖像,方便診斷醫(yī)師對(duì)GIST發(fā)生具體部位、腫瘤的大小、形態(tài)邊界、密度、生長(zhǎng)方式、胃腸道管腔、淋巴結(jié)或遠(yuǎn)處轉(zhuǎn)移等情況進(jìn)行精確分析,有利于提高診斷定位及定性準(zhǔn)確率,方便臨床進(jìn)行手術(shù)治療及預(yù)后處理,降低了手術(shù)風(fēng)險(xiǎn)及醫(yī)療事故發(fā)生率。MPR后處理技術(shù),是一個(gè)非常方便實(shí)用的技術(shù)。利用該技術(shù)對(duì)全身臟器的各種病變進(jìn)行冠狀位、矢狀位、水平位和斜位的重建,該技術(shù)在GIST的應(yīng)用,使得醫(yī)師能夠獲得更全面、更立體的圖像信息[14-15]。
綜上所述,128層螺旋CT檢查及MRP后處理技術(shù)可以取得高質(zhì)量的圖像,并且術(shù)后可隨訪復(fù)查,方便診斷醫(yī)師對(duì)病變進(jìn)行精確診斷,提高了診查效率,并可有效地指導(dǎo)臨床治療,對(duì)于優(yōu)化提升醫(yī)院的診療水平以及改善患者預(yù)后均具有積極意義。
