Methods From May 2009 to April 2010, 42 patients with vertebral body lesions underwent CT guided transpedicular biopsy. The clinical data including the puncture method, pahtological resutls, final diagnosis, and the pucture complications were retrospectively analyzed. Results The total accuracy rate of the puncture was 95.2%(40/42). The accuracy rate of the puncture was 94.3% (33/35) for malignant lesions and 100.0% (7/7) for benign lesions. No complication occurred. Conclusion CT guided transpedicular biopsy is very helpful in diagnosing vertebral body lesions with high accuracy and fewer complications.
目的 分析汶川大地震伤员的放射学表现特点。 方法 收集2008年5•12汶川大地震发生后至5月31日间213例地震伤员的完整放射学资料，着重分析伤员的X线、CT、MRI检查的影像学表现特点。 结果 213例中，同时行X线、CT、MRI检查10例（5%），X线、MRI检查7例（3%），X线、CT检查9例（4%），仅行CT检查5例（2%），仅行X线检查182例（85%）。MRI检查17例（8%）中，同时行胸椎和腰椎检查2例、颈椎和胸椎1例，颈椎1例，膝关节2例，上腹部1例，骨盆1例，腰椎9例；CT检查24例（11%）中，头部9例，胸部6例，腹部1例，脊柱6例，骨盆2例；X线检查208例中，单部位检查64例（31%），多部位检查144例（69%），仅有软组织受伤38例（18%），单纯肺挫伤6例（3%），骨折164例（79%）。 结论 地震伤员影像学检查以常规X线为主，头颅、五官受伤者首选CT，CT、MRI检查作为胸部、脊柱、关节等部位的补充检查。地震伤员以单纯性骨折为主，骨折合并脏器外伤较少。
预防和提高放射防护水平的关键在于获得放射照射的准确信息和有效的防护管理。放射防护涉及多方面的政策法规和影响因素,有国家和医疗机构对加强患者防护意识的培养,也有关于放射肿瘤学医生、放射物理师和技师需要掌握的信息,还有用于放射诊断、计划和治疗的放射设备学知识。这些不同门类的信息和方法应该在一个较好的管理平台上进行分类和运用,并给予有效地整合,才能降低临床工作中辐射的危害,获取医患双方的最大利益。
Objective To study the effect of the intracavity thrombolysis, aspiration of debris, percutaneous transcathete angioplasty (PTA) and percutaneous transtuminl angioplasty and stenting (PTAS) on treating peripheral arterial obliterans disease (PAOD). Methods From May 1994 to May 2008, interventional treatment was performed in 285 patients with PAOD. Intracavity thrombolysis and aspiration of debris were performed in 63 patients suffering from acute arterial occlusion. Intracavity thrombolysis and PTA were performed in 61 patients suffering from arteriostenosis combined with acute occlusion. Intracavity thrombolysis, PTA and PTAS were performed in 161 patients suffering from chronic arteriostenosis occlusion. Results Total success rate was 98.25% (280/285). The success rate in intracavity thrombolysis and aspiration of debris was 96.83% (61/63), with 88.89% (56/63) of the blood vessels restored, 7.94% (5/63) of the blood vessels partially restored, and another 3.17% (2/63) failed. The success rate in intracavity thrombolysis and PTA was 85.25% (52/61). The success rate in PTA and PTAS was 98.14% (158/161). The total complication rate was 7.02% (20/285), of them the local thrombolysis and thromboclasis accounting for 7.94% (5/63), the local thrombolysis and PTA accounting for 14.75% (9/61), the PTA and stent implantation accounting for 3.73% (6/161). Conclusion Percutaneous transluminal treatment for stenotic and occlusive lesions of peripheral artery can effectively keep the blood vessel unobstructed for a long time and raise the haemodynamics index remarkably.
Objective To summarize the development of process and clinical practice for radiomics. Methods Relevant literatures about the development of process and clinical practice of radiomics were collected to make a review. Results Radiomics, which resulting from big data, had been used in diagnosis, assessment of prognosis, and predictionof therapy response for neoplasm. Conclusion Radiomics is an important part of precision medical imaging in the eraof big data.
The management of malignant pleural effusion remains a clinical challenge. In November 2018, American Thoracic Society, Society of Thoracic Surgeons, and Society of Thoracic Radiology summarized the recent advances and provided 7 recommendations for clinical problems of the management of malignant pleural effusion. This paper interprets these recommendations to provide references for management and research on malignant pleural effusion.
Interventional radiology (IR) has developed rapidly since its introduction into our country. More and more patients choose this minimally invasive procedure for treatment, but the incidence of infectious complications and potential mortality following IR procedures should not be underestimated. As the number and breadth of IR procedures grow, it becomes increasingly evident that interventional radiologists and infection control practitioners must possess a thorough understanding of these potential infectious complications and put more emphasis on the quality of care, so as to control the infections and expenses, and maximize the patient safety. This article reviews infectious complications associated with percutaneous ablation of liver tumors, transarterial embolization of liver tumors, percutaneous transhepatic cholangial drainage, and intravascular stents or grafts. Emphasis is placed on incidence, risk factors, and prevention. With the use of these strategies, IR procedures can be performed with reduced risk of infectious complications.
