血管性帕金森综合征鉴别诊断的影像学研究进展 Advances of Imaging in the Differential Diagnosis of Vascular Parkinsonism

open access: yesZhongguo cuzhong zazhi, 2023
血管性帕金森综合征(vascular parkinsonism,VP)是临床上常见的继发性帕金森综合征,目前VP临床诊断和鉴别诊断的准确率较低,影响其临床治疗和预后。在临床实践中,影像学常用于VP的诊断。近年来多模态MRI和分子影像成像及分析技术等影像学技术的进展为提高VP的诊断和鉴别诊断准确率提供了客观手段。本文就前沿影像学技术在VP与原发性帕金森病以及其他非典型帕金森综合征鉴别诊断领域的研究进展进行综述,以期为VP的诊断和鉴别诊断提供新的思路。 Abstract: Vascular ...

Cushing综合征的临床特点与诊断分析

open access: yesZhongshan Daxue xuebao. Yixue kexue ban, 2008
【目的】分析Cushing综合征各种病因的临床特征,评估诊断和病因鉴别诊断的方法和效率。【方法】回顾分析我院1996年~2006年住院经临床和病理确诊为Cushing综合征的154例病例的临床资料和实验室检查资料。【结果】85%左右的病人有典型的Cushing外貌,肾上腺腺瘤占33.8%,其中85%为育龄女性。约半数病人出现低血钾和糖尿病。血糖异常、高血压及高脂血症的发生率分别为68.7%,72.6% and 67.6%。Cushing综合征诊断的敏感性从高到低依次为不被午夜1 mg地塞米松抑制、24 ...

胰腺实性假乳头状瘤的CT诊断要点 [PDF]

open access: yesZhongshan Daxue xuebao. Yixue kexue ban, 2017
【目的】探讨CT对胰腺实性假乳头状瘤(SPTP)的诊断和鉴别诊断价值。【方法】回顾性分析20例经手术病理证 实的SPTP患者CT表现,总结其CT特征。【结果】SPTP有实性及囊性结构,具有包膜,与正常胰腺组织分界清晰,常不伴有胰 管扩张;CT增强扫描动脉期肿瘤实质部分轻度强化,门静脉期及延迟期呈渐进强化。【结论】SPTP的CT表现具有相对特异 性,掌握其CT影像特点有助于对该病的早期诊断及鉴别诊断。

MSCT影像组学对Borrmann Ⅳ型胃癌与原发性胃淋巴瘤的鉴别诊断价值 [PDF]

open access: yes, 2022
目的探讨CT影像组学模型鉴别Borrmann Ⅳ型胃癌与原发性胃淋巴瘤的价值。方法回顾性收集2008年6月至2018年4月经手术或内镜病理确诊的Borrmann Ⅳ型胃癌或原发性胃淋巴瘤的病例共186例,其中Borrmann Ⅳ型胃癌132例,原发性胃淋巴瘤54例。采用计算机软件对CT动脉期、静脉期图像提取放射组学特征,再选择Lasso Logistic回归方法进行特征筛选,并建立CT影像组学模型,此外亦筛选CT主观征象构建CT主观征象模型,并同时利用CT主观征象及组学特征构建联合模型 ...

Sensitivity of a Hymenoptera serological immunoglobulin (Ig)E assay for the diagnosis of venom hypersensitivity in dogs

open access: yesVeterinary Dermatology, Volume 34, Issue 6, Page 543-553, December 2023., 2023
Background – Hymenoptera envenomation with honey bee (Apis mellifera) and paper wasp (Polistes spp.) may cause life‐threatening anaphylaxis in dogs. In human patients, clinical history, intradermal testing (IDT) and measurement of allergen‐specific serological immunoglobulin (Ig)E (sIgE) are used to support a diagnosis of Hymenoptera venom ...

Comparison of six anthropometric measures in discriminating diabetes: A cross‐sectional study from the National Health and Nutrition Examination Survey 六种人体测量指标在糖尿病鉴别诊断中的比较:一项来自国家健康与营养调查的横断面研究

open access: yesJournal of Diabetes, Volume 14, Issue 7, Page 465-475, July 2022., 2022
Highlights Our study retrospectively analyzed 46 979 members of the noninstitutionalized US population and found that anthropometric parameters, including weight, body mass index, waist circumference (WC), waist‐to‐height ratio (WtHR), A Body Shape Index, and conicity index (CI), had a significant positive correlation with diabetes. CI, a novel central‐
