The purpose was to investigate the difference of detection rate incidental pancreatic cystic lesions (PCLs) with computed tomography (CT) and magnetic resonance imaging (MRI) compare between CT MRI explore effect this on surgical resection. We reviewed diagnostic reports for PCLs 2013 2016. Images would be re-evaluated. Clinical data were recorded. chi-square independent t-test conducted categorical continuous variables. prevalence 1.91% (1038/54210) 3.36% (1282/38099) respectively,...
Multiple guidelines for pancreatic ductal adenocarcinoma (PDAC) suggest that all stages of patients need to receive postoperative adjuvant chemotherapy. S-1 is a recently emerged oral antitumour agent recommended by the guidelines. However, which population would benefit from needs be determined, and predictors chemotherapy response are needed personalized precision medicine. This pilot study aimed initially identify whether whole-tumour evaluation with MRI radiomics features could used...
Purpose To demonstrate the noninferiority of gadobutrol‐enhanced magnetic resonance imaging (MRI) compared with gadopentetate dimeglumine‐enhanced MRI in Asian patients referred for contrast‐enhanced body or extremities. Materials and Methods A multicenter, parallel‐group comparison study adults were randomized (1:1) to either gadobutrol dimeglumine. Lesions assessed three primary visualization variables: degree contrast enhancement, border delineation, internal morphology. Secondary...
Abstract We aimed to develop a predictive model based on texture features with non-contrast cardiac magnetic resonance (CMR) imaging for risk stratification toward adverse events in amyloidosis (CA) patients. A cohort of 78 CA patients was classified into training set (n = 54) and validation 24) at ratio 7:3. total 275 were extracted from CMR images. MaZda the support vector machine (SVM) utilized feature selection construction. SVM incorporating radiological built prediction endpoint by...
Objectives We aimed to develop a predictive model based on textural features of noncontrast cardiac magnetic resonance (CMR) imaging for risk stratification toward adverse events in patients with amyloidosis (CA). Methods A cohort 78 CA was grouped into training (n = 54) and validation 24) sets at ratio 7:3. total 275 were extracted from the CMR images. MaZda support vector machine (SVM) used feature selection construction. An SVM incorporating radiological built predict endpoint by...
Objective To investigate the value of MR perfusion parameters and ADC in diagnosis pancreatic cancer mass at 3.0 T MR. Methods Twenty healthy volunteers 25 patients with cancers proven by pathological results underwent PWI a scanner. A two-compartment model was used to quantify Ktrans, Kep Ve cancer, adjacent tissue, distal inflammatory tissue normal tissue. All among different tissues were analyzed compared ANONA. Fifteen 58 patients, including 30 (proven histopathologically), 9...
Abstract Background and aims: The recurrence metastasis of hepatocellular carcinoma (HCC) are mainly caused by microvascular invasion (MVI). Our study aimed to uncover the cellular atlas MVI + HCC investigate underlying immune infiltration patterns with radiomics features. Methods Three positive three negative samples were collected for single-cell RNA-seq analysis. 26 30 tissues underwent bulk For analysis, features score (Radscore) built using preoperative contrast MRI prediction overall...
Objective To investigate the CT and MRI imaging characteristics of autoimmune pancreatitis its clinical value. Methods Fourteen patients (13 males, 1 female, mean age 58.3 years) with proved histopathologically or clinically were enrolled in study.Clinical data was studied retrospectively.Among those patients,CT performed on 12 cases MR 8 patients,6 underwent both imaging. Results All 14 had enlargement pancreas,which could be divided into three types including diffuse type ( n =7 ),focal =5...
Objective To analyze the CT appearances with pathologic correlation and improve recognition of pancreatic mucinous cystadenoma/cystadenocarcinoma.Methods findings in 20 patients pathologically proven cystic tumor were retrospectively jointly reviewed by two observers blinded to pathological results.All underwent precontrast postcontrast helical CT.The number,size,location,and margins lesions observed,along wall thickness,septation,calcification witllin lesions.and presence mural nodules...
目的探讨扩散加权成像（diffusion-weighted imaging，DWI）中单指数模型和峰度模型在评估前列腺癌的Gleason评分（Gleason score，GS）方面的应用及差别。 方法连续收集复旦大学附属中山医院2017年5月至2018年12月期间疑诊前列腺疾病患者，进行多参数磁共振成像（multiparametric magnetic resonance imaging，mpMRI），包括常规序列、DWI、DCE-MRI。使用后处理软件分析DWI图像分别获得单指数模型参数表观扩散系数（apparent diffusion coefficient，ADC）及峰度模型参数Kapp及校正后的ADC-Dapp。使用Spearman相关分析检验癌区DWI参数与GS的相关性；单因素方差分析和独立样本t检验用于三组及两组间参数差异显著性分析，使用Kruskal-Wallis单因素方差分析（即κ样本）及Mann-Whitney U检验分别行三组及两组间非参数检验分析；通过ROC曲线来评估各参数鉴别诊断不同GS分组的效能。...
