摘要
目的探讨CT扫描及灌注成像在妇科盆腔肿瘤诊断中的应用价值。方法选择吉化集团公司总医院2011年2月～2012年12月收治的妇科盆腔肿瘤患者70例,均经病理诊断确诊,根据肿块良恶性分为良性组28例和恶性组42例,全部患者均行螺旋CT平扫及盆腔灌注扫描,对两组肿瘤的形态学及灌注指标比较。结果①CT平扫显示,恶性组肿块边界清晰者[9.5%(4/42)]明显少于良性组[75.0%(21/28)],盆腔淋巴结肿大[95.2%(40/42)]明显多于良性组[21.4%(6/28)],瘤体最大直径及扫描增强CT值[(5.74±2.39)cm、(33.25±10.38)Hu]明显明显高于良性组[(3.20±1.18)cm、(26.82±8.04)Hu],差异均有统计学意义(P<0.05)。②CT灌注扫描后处理显示,恶性组血流(BF)、血容(BV)、毛细血管表面通透性(PS)[(155.26±55.20)mL/(100 g)、(6.37±1.25)mL/(100 g)、(18.17±2.84)mL/(min.100 g)]明显高于良性组[(62.03±32.14)mL/(100 g)、(4.58±1.04)mL/(100 g)、(13.77±3.43)mL/(min.100 g)],平均通过时间(MTT)[(6.24±1.18)s]明显低于良性组[(7.89±2.16)s],差异均有统计学意义(P<0.05)。结论 CT灌注成像可有效评价盆腔肿块形态及血流灌注情况,在观察肿块形态特征的同时,对血流灌注情况进行定量观察,利于肿块良恶性的判定,有较高的利用价值及前景。
Objective To investigate the value of CT scans and perfusion imaging in the diagnosis of gynecological pelvic tumors. Methods 70 cases of gynecological pelvic tumor patients diagnosed by pathology in General Hospital of CNPC in Jilin from February 2011 to December 2012 were selected and all patients were divided into benign group with 28 cases and malignant group with 42 cases, all patients were given spiral CT scan and pelvic perfusion scan.Morphology and perfusion indexes of gynecological pelvic tumor in the two groups were compared. Results ①The rate of clear boundary in malignant group [9.5% （4/42）] was lower than that in benign group [21.4% （6/28）], the rate of pelvic lymph node enlargement n malignant group [95.2% （40/42）] was higher than that in benign group [21.4% （6/28）], the largest diameter of tumors and the scan-enhanced CT value in malignant group [（5.74±2.39） cm, （33.25±10.38） Hu]were higher than those in benign group [（3.20±1.18） cm, （26.82±8.04） Hu], the differences were statistically significant （P 〈 0.05） according to the CT plain scan. ②BF, BV, PS in malignant group [（155.26±55.20） mL/（100 g）, （6.37±1.25） mL/（100 g）, （18.17＋2.84） mL/（min· 100 g）] were higher than those in benign group [（62.03±32.14） mL/（100 g）, （4.58±1.04） mL/（100g）, （13.77±3.43） mL/（min. 100 g）], MTY in malignant group [（6.24±1.18） s] was lower than that in benign group [（7.89±2.16） s], the differences were statistically significant （P 〈 0.05） according to the CT perfusion scanning. Conclusion CT perfusion imaging can evaluate pelvic tumor morphology and perfusion, it can get quantitative perfusion observation at the same time of tumor morphological characteristics observation, it is conducive to judge the optimum and malignancy, so it has high value and prospects.
