【摘要】：目的： 了解MSCT結(jié)合仿真內(nèi)鏡對(duì)結(jié)直腸癌的診斷價(jià)值。 材料與方法： 收集2010年10月-2011年11月45例結(jié)直腸疾病患者的臨床及影像學(xué)資料，男27例，女18例，年齡21-74歲，平均年齡47.5歲。45例患者行電子結(jié)腸鏡、CT結(jié)腸仿真內(nèi)鏡檢查及手術(shù)病理證實(shí)。全部患者均行腸道準(zhǔn)備及腸腔內(nèi)注氣后用Definition AS+128層螺旋CT進(jìn)行掃描。其中32例行CT平掃加增強(qiáng)掃描，13例行CT平掃。平掃時(shí)掃描體位為仰臥位及俯臥位各一次。圖像重建層厚1mm。應(yīng)用后處理工作站colon軟件進(jìn)行圖像后處理，評(píng)價(jià)病變的部位、形態(tài)、大小、侵犯范圍、有無(wú)其它器官及淋巴結(jié)轉(zhuǎn)移。 結(jié)果： 45例患者中，病理證實(shí)結(jié)、直腸癌42例，，炎癥3例。42例腫瘤性病變（20例結(jié)腸癌、22例直腸癌），其中腫塊型17例、浸潤(rùn)型10例、潰瘍型6例、混合型9例。4例發(fā)現(xiàn)肝臟轉(zhuǎn)移、39例淋巴結(jié)轉(zhuǎn)移。CT結(jié)腸仿真內(nèi)鏡與電子結(jié)腸鏡對(duì)結(jié)腸腫瘤的檢出、定性及定位比較的差異P＞0.05，無(wú)統(tǒng)計(jì)學(xué)意義。 結(jié)論： 多層螺旋CT結(jié)合仿真內(nèi)鏡對(duì)結(jié)直腸腫瘤的檢出、定位、定性的準(zhǔn)確率較高；對(duì)觀察病灶周?chē)那址盖闆r及有無(wú)遠(yuǎn)處器官和淋巴結(jié)轉(zhuǎn)移的情況有很大的優(yōu)勢(shì)，同時(shí)還可以了解腸腔內(nèi)病變的形態(tài)及病變累及腸腔的長(zhǎng)度。
[Abstract]:Objective: To investigate the diagnostic value of MSCT combined with virtual endoscopy in colorectal cancer. Materials and methods: The clinical and imaging data of 45 patients with colorectal diseases from October 2010 to November 2011 were collected. There were 27 males and 18 females aged 21-74 years, with an average age of 47.5 years. All patients were scanned with Definition as 128 slice spiral CT after intestinal preparation and intraluminal gas injection. In 32 cases, CT plain scan and enhanced CT scan were performed in 13 cases. The scanning position was in supine position and prone position respectively. The thickness of image reconstruction layer is 1 mm. The post processing workstation colon software was used to evaluate the location, shape, size, invasion range, other organs and lymph node metastasis. Results: Among the 45 cases, 42 cases were confirmed by pathology, 42 cases were inflammation, 20 cases were carcinoma of colon cancer, 17 cases were mass type, 10 cases were infiltrating type, 6 cases were ulcer type. Liver metastasis was found in 39 cases of mixed type. Ct virtual endoscopy and electronic colonoscopy were used to detect colon tumor (P > 0.05), and there was no significant difference between qualitative and localization (P > 0.05). Conclusion: Multi-slice spiral CT combined with virtual endoscopy has a high accuracy in detecting, locating and determining colorectal tumors, and has great advantages in observing the invasion around the lesion and the presence of distant organs and lymph node metastasis. At the same time, we can understand the shape of the lesions and the length of the lesions involved in the lumen.
