Abstract Purpose: To retrospectively assess apparent diffusion coefficients (ADCs) of different subtypes pancreatic endocrine tumors based on the World Health Organization (WHO) classification system and analyze potentially responsible histopathologic characteristics. Materials Methods: Following Institutional Review Board (IRB) approval, 18 patients with surgical pathology‐proven were evaluated. Tumors subcategorized WHO grading into well‐differentiated benign uncertain behavior carcinomas...
Abstract Purpose: To compare the diagnostic accuracy of magnetic resonance imaging elastography (MRE) and anatomic MRI features in diagnosis severe hepatic fibrosis cirrhosis. Materials Methods: Three readers independently assessed presence morphological changes associated with 72 patients liver biopsy including: caudate to right lobe ratios, nodularity, portal venous hypertension (PVH) stigmata, posterior notch, expanded gallbladder fossa, vein caliber. measured shear stiffness values using...
Purpose The purpose of this study was to develop and validate a deep learning (DL)‐based radiomics model predict the response chemotherapy in colorectal liver metastases (CRLM). Methods In retrospective study, we enrolled 192 patients diagnosed with CRLM who received first‐line were followed by assessment. Tumor identified according Response Evaluation Criteria Solid Tumors (RECIST). Contrast‐enhanced multidetector computed tomography (MDCT) images fed as inputs ResNet10‐based DL model,...
Abstract Objectives Patients with IgG4-related disease (IgG4-RD) typically respond well to initial glucocorticoid therapy, but always relapse tapered or maintenance dosage of steroid. We aimed identify the risk factors for IgG4-RD and explore impact active intervention on serologically unstable condition. Methods performed a retrospective study 277 patients at Peking University People’s Hospital from February 2012 through 2019. They were all followed >4 months. The primary outcome was...
Abstract The 2024 updates of the Chinese Society Clinical Oncology (CSCO) Guidelines for diagnosis and treatment colorectal cancer emphasize standardizing in China, highlighting latest advancements evidence‐based medicine, healthcare resource access, precision medicine oncology. These address disparities epidemiological trends, clinicopathological characteristics, tumor biology, approaches, drug selection patients across diverse regions backgrounds. Key revisions include adjustments to...
To assess the benefits and limits of surgery for primary hepatic lymphoma (PHL), probability survival after postoperative chemotherapy.A retrospective analysis was undertaken to determine results surgical treatment PHL over past 8 years. Only nine patients underwent such treatment. The detailed data diagnosis, treatment, prognosis were carefully studied.All mistaken as having α-fetoprotein-negative cancer before pathological diagnosis. mean delay time between initial symptoms final diagnosis...
Preoperative and noninvasive prognosis evaluation remains challenging for gastric cancer. Novel preoperative prognostic biomarkers should be investigated. This study aimed to develop multidetector-row computed tomography (MDCT)-guided models direct follow-up strategy improve prognosis.A retrospective dataset of 353 cancer patients were enrolled from two centers allocated three cohorts: training cohort (n = 166), internal validation 83), external 104). Quantitative radiomic features extracted...
MRI-based oxygen extraction fraction imaging has a great potential benefit in the selection of clinical strategies for ischemic stroke patients. This study aimed to evaluate performance challenge-free (OEF) mapping cohort acute and subacute Consecutive patients (a total 30 with 5 stage, 19 early 6 late stage) were recruited. All subjects underwent MRI including multi-echo gradient echo (mGRE), diffusion weighted (DWI), 3D-arterial spin labeling (ASL). OEF maps generated from mGRE phase +...
Blood-pool (BP)–gated SPECT should be able to detect regional left ventricular (LV) dysfunction, as the modality is fully 3-dimensional and capable of resolving all cardiac chambers. This study investigates hypothesis that LV segments have abnormal wall motion (WM) on a MRI scan also BP ejection fraction (EF) computed by automated quantitation (AQ) data. Methods: A total 34 patients evaluated for coronary artery disease who underwent visual assessment WM review cines evaluations were...
Abstract Purpose: To determine the accuracy of diffusion‐weighted imaging (DWI) in discrimination metastatic lymph nodes (LNs) gastric carcinoma with rigorous histopathological correlation. Materials and Methods: With Institutional Review Board (IRB) approval, 28 patients underwent magnetic resonance (MRI) DWI before surgery. LNs were resected at surgery thereafter submitted for analyses. All histopathologically identified (≥5 mm) that exactly matched location size on MRI/DWI to...
Retroperitoneal fibrosis (RPF) is an uncommon condition characterized by inflammation and in the retroperitoneal space. More than two-thirds of RPF are idiopathic, with remaining stemed from a variety secondary causes. It was suggested that IgG4-related form RPF. We undertook this study to compare detailed demographic, clinical laboratory characteristics IRPF large Chinese cohort. retrospectively reviewed medical records 132 patients diagnosed at Peking University People’s Hospital between...
Background Breast MRI has been recommended as supplemental screening tool to mammography and breast ultrasound of cancer by international guidelines, but its long examination time use contrast material remains concerning. Purpose To develop an unenhanced radiomics model with using non‐gadolinium based sequences for detecting on T2‐weighted (T2W) diffusion‐weighted (DW) MRI. Study Type Retrospective analysis followed retrospective prospective cohorts study. Population 1760 patients: Of these,...
To assess whether elevated serum carcinoembryonic antigen (CEA) is in the inferior prognosis for pathological lymph node-negative (pN0) gastric cancer (GC) patients who underwent D2 gastrectomy.About 469 pN0 GC patients, received radical gastrectomy were retrospectively analyzed. The X-tile plots cut-off point CEA 30.02 ng/mL using minimum P-value from log-rank χ2 statistics, and assigned to two groups: those more than (n = 48; CEA-high group) less 421; CEA-low group). Clinicopathologic...
Background: Early gastric carcinoma (EGC) with pure signet ring cell (pSRCC) has been reported to have favourable prognosis and low risk of lymph node metastasis (LNM). However, factors LNM clinicopathological features for early mixed (mSRCC) remain poorly investigated. The aim this study was identify compare characteristics pSRCC mSRCC. Methods: This retrospective conducted at our center between 2005 2015 in 796 patients underwent radical gastrectomies combined dissections, A total 160 SRCC...
OBJECTIVE. This study aimed to investigate the 3-year progression-free survival (PFS) of patients with stage T4a gastric cancer extramural vessel invasion (EMVI) detected contrast-enhanced (CE) MDCT. In addition, we investigated possibility that CT EMVI could improve clinical nodal (N) staging. MATERIALS AND METHODS. retrospective included 143 cancer. Clinical staging was performed CE-MDCT. All underwent radical gastrectomy extended lymphadenectomy, adjuvant chemotherapy, and conventional...
