摘要目的术前针刺活检对导管内原位癌有无浸润漏诊在20%以上。术前诊断为无浸润征象的导管内原位癌(即纯导管内原位癌)的病人中,20%以上病人的针刺活检低估了浸润。本研究的目的是评价MRI鉴别术前导管原位癌浸润性高低的能力。方法对125例术前针刺活检诊断为纯导管内原位癌(128个病灶,3个为双侧)病人进行前瞻性研究。所有病人均进行了乳腺手术。分别对乳腺X线摄影、组织学(活检)和MRI表现进行评估,分析其侵犯特征。

目的评价一种新的幼年型关节炎MR评分系统(JAMRIS)在评估膝关节疾病活动性方面的可靠性及反应性。方法用开放式1TMR设备对25个临床诊断累及膝关节的幼年特发性关节炎(JIA)病人进行研究。5个阅片者应用JAMRIS系统分别对滑膜增厚、骨髓改变、软骨病变和骨质侵蚀的MRI表现进行独立评分。此外,决定采用JAMRIS系统作为随访参数,由2名阅片者评价15个连续的JIA病人对治疗的反应。结果 JAMRIS评估功能的阅片者间(ICCs0.86～0.95)和阅片者本身(ICCs0.92～1.00)的可靠性良好。所有项目的实际评分和随时间改变的评分的可靠性都是好的,ICCs分别是0.89～1.00,0.87～1.00。关于治疗反应,治疗后的平均滑膜增厚评分显著下降(平均1.1个百分点,P<0.001,SRM=-0.65)。而骨髓改变、软骨病变和骨质侵蚀评分没有变化。结论 JAMRIS被证明是一种在评价膝关节JIA病活动性方面既简便又高度可靠的评估方法。JAMRIS系统可能会作为一种客观又准确的观察指标应用于将来的研究及临床试验中。要点①MRI在诊断和评估幼年特发性关节炎方面的应用正在不断增加。②一种简便又可靠的评分方法有助于监测进展和进行研究。③JAMRIS系统提供了客观可靠的测量方法。④JAMRIS可以评估滑膜增厚、骨髓改变、软骨病变和骨质侵蚀的情况。⑤JAMRIS系统可以监测治疗反应,应该有助于未来的研究。

AIM:To retrospectively evaluate the imaging features of pancreatic intraductal papillary mucinous neoplasms (IPMNs) in multi-detector row computed tomography (MDCT).METHODS: A total of 20 patients with pathologically-confirmed intraductal papillary mucinous neoplasms (IPMNs) were included in this study. Axial MDCT images combined with CT angiography (CTA) and multiplanar volume reformations (MPVR) or curved reformations (CR) were preoperatively acquired. Two radiologists (Tan L and Wang DB) reviewed all the images in consensus using an interactive picture archiving and communication system. The disputes in readings were resolved through consultation with a third experienced radiologist (Chen KM). Finally, the findings and diagnoses were compared with the pathologic ***: The pathological study revealed 12 malignant IPMNs and eight benign IPMNs. The diameters of the cystic lesions and main pancreatic ducts (MPDs) were significantly larger in malignant IPMNs compared with those of the benign IPMNs (P<0.05). The combined-type IPMNs had a higher rate of malignancy than the other two types of IPMNs (P<0.05). Tumors with mural nodules and thick septa had a significantly higher incidence of malignancy than tumors without these features (P<0.05). Communication of side-branch IPMNs with the MPD was present in nine cases at pathologic examination. Seven of them were identified from CTA and MPVR or CR images. From comparison with the pathological diagnosis, the sensitivity, specificity, and accuracy of MDCT in characterizing the malignancy of IPMN of the pancreas were determined to be 100%, 87.5% and 95%, ***: MDCT with CTA and MPVR or CR techniques can elucidate the imaging features of IPMNs and help predict the malignancy of these tumors.

Objective: To evaluate the expectations and experience of patients undergoing mini-arthroscopy compared to contrast enhanced MRI for research purposes. Methods: Seventeen patients with early, active arthritis (Group A) and 21 autoantibody-positive individuals without any evidence of arthritis upon physical examination (Group B) were included. All subjects underwent both contrast enhanced MRI and synovial biopsy sampling by mini-arthroscopy of the same joint within one week. At inclusion and after both procedures, subjects filled in questionnaires with items about expectations and experience with regard to the procedures. Results: Before procedures, subjects in group B had a higher fear of and reluctance to undergo mini-arthroscopy compared to MRI (p < 0.0001 and p = 0.001, respectively). Before procedures, 42% of the subjects preferred MRI, 11% of the subjects preferred mini-arthroscopy and 47% had no preference for either procedure. After both procedures, subjects preferences changed to 39% for MRI, 32% for mini-arthroscopy and 29% for no preference for one or the other procedure. When comparing Group A with Group B, there were no significant differences in preference before and after the procedures. Conclusion: Synovial biopsy sampling by mini-arthroscopy for analysis of synovial inflammation is a well-experienced procedure when compared to contrast enhanced MRI. These results support the use of mini-arthroscopy in a research setting from a patient perspective.
