目的 探究癌胚抗原(CEA)血清学、细胞学、影像学检测以及三者联合检测对肺癌的诊断价值.方法 对358例住院患者进行血清CEA和纤维支气管镜刷片细胞学检测,然后对血清CEA检测阳性的156例患者同时进行肺部CT检测,将3种检查结果进行比较分析.结果 358例进行血清CEA检测的患者中有156例阳性;358例进行纤维支气管镜刷片细胞学检测的患者中有97例阳性;156例CEA阳性病例进行肺部CT检查,其结果中有79例阳性;202例CEA阴性的病例进行肺部CT检查,结果均为阴性.临床最终诊断为肺癌的患者有83例.结论 在肺癌的筛查方法中,血清学方法灵敏度高,但特异度较低;细胞学检测特异度高,是肺癌的确诊指标;CT检查特异度高并可以初步确定病变部位;3种方法联合检测更有利于肺癌的早期诊断.

目的:探讨胶片—报告自助打印系统在放射科应用情况,我院共计投放12台自助式胶片报告打印机,分析取胶片与报告情况,观察胶片及报告匹配识别情况和废弃胶片积压情况,记录机器故障情况.平均每天约有98.7%患者通过自助打印机顺利取到检查结果与胶片,0.75%自助取结果失败.0.55%患者因各种原因未取结果.该系统使用后提高放射科工作效率,降低工作量,减少医患纠纷.

本文探讨早期股骨头缺血坏死的高危因素,回顾分析性251例疑诊股骨头缺血坏死患者资料,对年龄、性别、骨密度、酗酒、激素使用等7项可能的因素进行单因素及多因素分析.单因素分析显示年龄、骨密度、酗酒及激素使用为可能影响因素(P<0.05),其中性别、酗酒史及激素使用史为危险因素.

In order to study the radiological features of osteogenesis imperfecta(OI),the X-ray and clinic information of 18 patients(16 adults and 2 foetus)with OI were reviewed.Most X-ray films of OI patients showed multiple fractures,periosteal reaction,metaphyseal sclerosis,morphologic changes of bones and articulations,spinal lateral curvature,basilar impression,osteopenia,etc.

Objective: To assess the diagnostic value of X ray and CT in HIV-positive patients with Pneumocystis carinii pneumonia (PCP). Methods: The clinical and radiologic data of 42 HIV-positive patients with PCP were analyzed retrospectively. All patients had X ray (normal X ray and digital X ray) examination and 24 patients of them had CT examination. Results: Twenty-six patients (61. 9%) diagnosed as PCP had typical diffuse reticular and nodular form of two lung lobes' symmetry and patching form of high density image in X-ray photos, and was the accuracy rate of diagnosis was 100%. Sixteen cases of non-typical X-ray evidents took CT scan. By CT diagnosis, the appearances of 9 cases (21. 4%) had multifocal, multicystic, and parenchymatous changes. Another seven cases' lesion locations and imaging performances were not typical. Four among the seven cases (9.5%) were lobular leachability affection and three cases (7.1%) were grandifoliate and focal consolidation. Only one of the seven cases made a final diagnosis after CT scans. The other six cases could not diagnosed definitely. X ray and CT examination of diagnosis of PCP in HIV infected patients was 85.7%. Conclusion: For the diagnosis of typical PCP in X-ray, the accuracy rate is 100%. But for those without typical performances in X-ray, the patients should take CT examination. The diagnostic rate of X ray combined with CT is 85.7% in diagnosing HIV infected patients with PCP.

医用X射线在医疗卫生领域得到广泛应用.人们在接受X线检查的同时,也受到一定程度的伤害.因此,2006年3月1日国家颁布了《放射诊疗管理规定》,旨在加强放射工作管理,这也对X射线的防护工作提出了更多更高的要求.

目的:探讨艾滋病(AIDS)合并肺结核影像学特征.方法:收集32例艾滋病合并肺结核患者的临床及影像学资料(X线胸片检查,其中14例经CT检查),并进行分析.结果:原发性肺结核6例(18.7%),表现肺门纵隔淋巴结肿大,1例伴有肺不张;亚急性血型播散型肺结核12例(37.5%),两肺多发性大小不等的结节;浸润型肺结核14例(43.7%),表现为陈旧性病灶周围炎,伴空洞及播散病灶,病变范围较广.结论:AIDS中晚期合并肺结核主要为原发肺结核及广泛播散病变.

Objective To evaluate the implication of digital image in lung cancer model of rats and the quality of radiology on digital image. Methods 140 Wistar rats were perfused with tumor-inducilble iodinated-oil in left pulmonary by digital image and quality of the photo was compared with that of the other 56 rats'conven-tional radiology. Results The graphic quality in digital image group was better than that of conventional radiology which the rats of A,Band C grade graphic quality was 39.3%, 10.7%and 0% respectively vs 71.4%,23.2%and 5.4% in conventional group. Conclusion digital image is superior to the conventional radiology in graphic quality for evaluating rats's model of lung cancer.

由于建筑施工造成的意外事故发生率较高,高空坠地、重物挤压,大多是青中年民工,伤员多在很急情况下送放射科摄片.结合多年临床摄片经验,对多发性肋骨骨折摄片强调如下要点.
