Purpose: The differences between the Alberta Stroke Program Early CT Score (ASPECTS) obtained by experts and artificial intelligence (AI) software require elucidation. We aimed to characterize the discrepancies between the ASPECTS obtained by AI and experts and determine the associated factors and prognostic implications.
Methods: This multicenter, retrospective, observational cohort study included patients showing acute ischemic stroke caused by large-vessel occlusion in the anterior circulation.
Background: This study aims to investigate the value of radiomics parameters derived from contrast enhanced (CE) MRI in differentiation of hypovascular non-functional pancreatic neuroendocrine tumors (hypo-NF-pNETs) and solid pseudopapillary neoplasms of the pancreas (SPNs).
Methods: Fifty-seven SPN patients and twenty-two hypo-NF-pNET patients were enrolled. Radiomics features were extracted from T1WI, arterial, portal and delayed phase of MR images.
Article Synopsis
- The study aimed to evaluate and compare three different techniques for placing regions of interest (ROIs) to measure the apparent diffusion coefficient (ADC) in patients with pancreatic ductal adenocarcinoma (PDAC).
- Involving 21 PDAC patients and 18 healthy volunteers, researchers used diffusion-weighted imaging to assess ADCs, with measurements taken using whole-volume, single-slice, and small solid tumor samples.
- Results showed that ADCs from small solid samples provided the most accurate diagnosis of PDAC, significantly outperforming the other two methods based on their ROC curve areas, prompting a recommendation for using solid sample placements in clinical assessments.
Purpose: To assess the influence of region of interest (ROI) on tumor apparent diffusion coefficient (ADC) measurements and interobserver variability in pancreatic ductal adenocarcinoma (PDAC).
Materials And Methods: Twenty-two patients recruited with pathology-proven PDAC underwent diffusion-weighted imaging (DWI, 3.0T) prior to the surgical resection.
Background: To investigate the monoexponential and biexponential apparent diffusion parameters in different anatomical regions of the healthy pancreas using intravoxel incoherent motion (IVIM) diffusion weighted imaging (DWI).
Methods: Fifty-seven healthy volunteers (age, 45.0 ± 10.
