摘要:目的:分析讨论乳腺癌诊断中应用MRI、CT和全数字化乳腺X线摄影的临床应用价值。方法:选取本院2017年1月-2018年12月乳腺疾病患者200例,对所有研究对象先后进行MRI、CT和全数字化乳腺X线摄影检查。比较三种检查方式对乳腺癌的诊断率。结果:MRI、CT和全数字化乳腺X线摄影诊断率依次为93.00%、80.50%和77.50%,MRI诊断率明显高于CT和全数字化乳腺X线摄影,P<0.05。结论:MRI能够有效诊断乳腺癌,但MRI检查费用较高,可优先使用CT和全数字化乳腺X线摄影检查。

Abstract: Objective: To analyze the application value of MRI(magnetic resonance imaging), CT(computed tomography) and full-field digital mammography in the diagnosis of breast carcinoma. Methods: 200 breast disease patients checked from January 2017 to December 2018 in our hospital were selected. MRI, CT and full-field digital mammography was performed for all subjects one after another. The diagnosis rate of breast carcinoma based on three examination methods was compared. Results: The diagnosis rate of breast carcinoma based on MRI, CT and full-field digital mammography was 93.00%,80.50% and 77.50%, the diagnostic rate of MRI was significantly higher than that of CT and full-field digital mammography(P<0.05). Conclusion: MRI can take the efficient diagnosis of breast carcinoma, but its examination costs are higher as well. Therefore, CT and full-field digital mammography can be primarily recommended in clinical practice.

临床对于乳腺癌的治疗原则是早发现、早治疗,因此,良好检查方式对于乳腺癌患者而言意义重大[1]。CT和全数字化乳腺X线摄影是两种成本较低廉的检查方式,重复性较好,操作简单,适合临床检查[2]。相比之下,MRI相对复杂,但准确性也明显升高。我院在乳腺疾病诊断中应用MRI、CT和全数字化乳腺X线摄影三种检查方式,现将研究结果报告如下。
1 资料和方法
1.1 一般资料
选取200例乳腺疾病患者,所有研究对象在2017年1月-2018年12月接受影像学检查,所有研究对象先后进行MRI、CT和全数字化乳腺X线摄影检查。其中,所有患者均为女性,年龄20-55岁,平均年龄(39.4±5.2)岁。
1.2 方法
1.2.1 全数字化乳腺X线摄影
使用GIOTTO全数字化乳腺钼靶摄影机(意大利吉特)。医护人员安排患者常规拍摄双侧乳腺头尾位、内外斜位,必要时加照侧位,夸大头尾位或其他特殊部位。
1.2.2 CT检查
使用SOMATOM Definition FLASH CT(西门子)。患者采用仰卧位,颈胸交界及腹部都由棉垫垫高,确保双侧乳腺充分悬垂。先进行平扫,然后增强扫描。CT扫描设置参数为120kV,CareDose4D,层厚1mm,层距1mm,螺距0.5,增强扫描时给予患者75.0-100.0ml碘对比剂注射,注射速度为3.0ml/s。……
