目的:讨论分析使用磁共振弥散加权成像(DWI)在肺癌引起的阻塞性肺不张的诊断与鉴别中的应用方法选择我院在2014年2月-2016年10月期间收治的经过行X线胸片检查初步检查考虑有阻塞性肺不张的病例53例,对上述病例现进行胸部CT的检查,接着再对患者进行磁共振弥散加权成像(DWI),最后再对53例患者进行病理活检对疾病进行进一步的确诊。结果:在进行了检查的53例患者当中,患者X线初步检查,均考虑患者出现了阻塞性肺不张,对患者进行CT检测之后,考虑患者患有中央型肺癌引起的阻塞性肺不张的患者有46例,7例患者患有单纯性阻塞性肺不张;对患者进行磁共振弥散加权成像检查判断患者患有中央型肺癌引起的阻塞性肺不张的患者有51例,单纯性阻塞性肺不张的患者2例。对上述的所有的患者均进行进一步的病理活检,病检的结果显示,中央型肺癌引起的阻塞性肺不张的患者有51例,单纯性阻塞性肺不张的患者2例。结论:DWI在肺癌的诊断包括中央型肺癌的疾病的诊断上,具有较高的确诊率。
OBJECTIVE: To discuss the application of diffusion weighted imaging (DWI) in the diagnosis and differential diagnosis of obstructive pulmonary atelectasis caused by lung cancer.Methods To select the patients who underwent X-ray in our hospital from February 2014 to October 2016, Preliminary examination of chest X-ray examination 53 cases of obstructive pulmonary atelectasis were considered. Thoracic CT examination was performed on the above cases, and then magnetic resonance diffusion-weighted imaging (DWI) was performed on the patients. Finally, pathological biopsy was performed on 53 patients Further diagnosis of the disease. RESULTS: Of the 53 patients examined, a preliminary examination of the patient’s X-ray took into account that the patient developed obstructive atelectasis. After CT examination of the patient, consider patients with central lung cancer-causing obstructive atelectasis Of the 46 patients, 7 patients with simple obstructive atelectasis; patients with magnetic resonance diffusion-weighted imaging to determine the patients suffering from central lung cancer caused by obstructive atelectasis in patients with 51 cases of simple Two cases of obstructive atelectasis. All of the above patients underwent further pathological biopsy. The results of the pathological examination showed that there were 51 patients with obstructive pulmonary atelectasis caused by central lung cancer and 2 patients with simple obstructive pulmonary atelectasis. Conclusion: DWI has a high diagnosis rate in the diagnosis of lung cancer including those of central lung cancer.
