【摘要】：目的：探討雙源CT檢查對(duì)膀胱癌的價(jià)值,建立合理的膀胱癌CT檢查程序,早期發(fā)現(xiàn)膀胱腫瘤。 方法：回顧分析32例膀胱腫瘤患者的臨床資料,均行雙源CT檢查,常規(guī)禁食8小時(shí),檢查前1.5-2時(shí)內(nèi)飲水1000-1500m1,待患者有尿意時(shí)行CT檢查,在膀胱充分充盈后,行CT平掃和增強(qiáng)掃描(包括動(dòng)脈期、靜脈期、平衡期、多排泄期)。將不同時(shí)相的數(shù)據(jù)分別應(yīng)用多層面后重建技術(shù)(MPR)進(jìn)行處理,分別記錄病變的位置、大小、數(shù)目等。 結(jié)果：32例膀胱癌患者經(jīng)手術(shù)確診。平掃M(jìn)PR、動(dòng)脈期MPR、靜脈期MPR、平衡期MPR、多排泄期MPR檢查方式對(duì)膀胱癌的檢出率分別為68.52%、88.89%、92.59%、90.74%、94.44%。平掃M(jìn)PR的檢出率明顯低于其他四種方式(PO.05),有統(tǒng)計(jì)學(xué)意義。動(dòng)脈期MPR、靜脈期MPR、平衡期MPR、多排泄期MPR方式對(duì)膀胱癌的檢出率無(wú)統(tǒng)計(jì)學(xué)差異。 結(jié)論：雙源CT成像提高了診斷膀胱癌的準(zhǔn)確性,在膀胱充分充盈后,行全泌尿系統(tǒng)掃描,應(yīng)用后處理技術(shù)分別重組靜脈期、多排泄期掃描圖像,是診斷膀胱癌安全、可靠的方法。
[Abstract]:Objective: to evaluate the value of dual-source CT in bladder cancer and to establish a reasonable procedure for early detection of bladder cancer.Methods: the clinical data of 32 patients with bladder tumor were retrospectively analyzed. All patients were examined by dual source CT, fasting for 8 hours, drinking water 1000-1500ml within 1.5-2 hours before examination.Plain and contrast-enhanced CT scans (including arterial phase, venous phase, balance phase, multiple excretion phase) were performed.The different phase data were processed by multi-layer post-reconstruction technique (MPRs), and the location, size and number of lesions were recorded respectively.Results 32 cases of bladder cancer were diagnosed by operation.The detectable rate of MPR in plain scan, arterial phase, venous phase, balance phase and multiple excretion phase were 68.52 and 88.899.599.90.744.44, respectively.The detection rate of MPR in plain scan was significantly lower than that in other four ways (P < 0.05).There was no significant difference in the detection rate of bladder cancer between arterial phase, venous phase, equilibrium phase and multiple excretion phase MPR.Conclusion: Dual-source CT imaging can improve the accuracy of diagnosis of bladder cancer. It is safe to use post-processing technique to recombine the venous phase and multiple excretion phase of bladder cancer after the full filling of bladder.A reliable method.
