目的:探讨分析宫颈癌诊断中应用16排螺旋CT多期增强扫描及三维重建的临床价值。方法:对我院2012年6月至2014年6月期间经活检病理证实的40例宫颈癌患者行16排螺旋CT多期增强扫描,并在重建处理后呈现多平面图像。结果:40例患者病症分期均超过Ⅱ期,宫颈肿块直径均超过4cm。Ⅱa期9例,CT检出8例,其中高估为Ⅱb期2例;Ⅱb期11例,CT检出11例,其中低估为Ⅱa期3例;Ⅲb期11例、Ⅳb期9例,CT全部检出,分期诊断均正确。Ⅱa期患者肿瘤入侵阴道上2/3;Ⅱb期患者肿瘤入侵子宫旁组织,显示结节影或者不规则条索影,距盆壁肌肉3mm以上;Ⅲb期患者肿瘤入侵子宫旁组织,伴有淋巴结转移现象;Ⅳb期患者肿瘤入侵膀胱直肠,伴有盆腔淋巴结转移现象。结论:在宫颈癌诊断中应用16排螺旋CT多期增强扫描及三维重建的临床价值非常高,可以对宫颈肿块生长及入侵情况予以显示,对临床分期与诊治有着十分重要的意义。
Objective: To investigate the clinical value of 16-slice spiral CT multi-phase contrast-enhanced scanning and three-dimensional reconstruction in the diagnosis of cervical cancer. Methods: Forty cases of cervical cancer confirmed by biopsy pathology from June 2012 to June 2014 in our hospital were scanned by multi-slice spiral CT with 16-slice spiral CT, and multiplanar images were obtained after reconstruction. Results: All the 40 patients had more than two stages of disease. The diameters of cervical masses exceeded 4 cm. Ⅱa period in 9 cases, CT was detected in 8 cases, of which 2 cases were overestimated for stage Ⅱ b; Ⅱ b 11 cases, 11 cases were detected by CT, which underestimated for Ⅱ a 3 cases; Ⅲ b 11 cases, Ⅳ b 9 cases, CT All detection, staging diagnosis are correct. Stage IIa tumor invasion of the vagina on the 2/3; IIb patients with tumor invasion of the uterine tissue, showing nodules or irregular cords, from the pelvic muscles more than 3mm; Ⅲ b patients with tumor invasion of the uterine tissue with lymph nodes Metastasis; Ⅳ b tumor invasion of the bladder and rectum, accompanied by pelvic lymph node metastasis. Conclusion: The clinical value of multi-slice enhanced scan and three-dimensional reconstruction of 16-slice spiral CT in the diagnosis of cervical cancer is very high, which can display the growth and invasion of cervical mass. It is of great significance for clinical staging and diagnosis and treatment.
