CT‐derived quantitative imaging metrics for pathological assessment of stage I pulmonary invasive adenocarcinoma: For the diagnostic examination, uAI Intelligent Imaging System was employed

VIEW, EarlyView.
This study explored uAI‐derived quantitative CT features for pathological grading of stage‐I invasive lung adenocarcinoma. Using 5‐fold cross‐validation, the Random Forest model achieved optimal discriminatory performance (mean AUC = 0.799). Attenuation and texture CT features enable non‐invasive grading and may assist clinical decision‐making ...

Characterization and differentiation of body fluids, putrefaction fluid, and blood using Hounsfield unit in postmortem CT [PDF]

, 2014
The purpose of the present study was to evaluate the ranges of Hounsfield unit (HU) found in body fluids, putrefaction fluids, and blood on postmortem CT and how these ranges are affected by postmortem interval, temperatures, and CT beam energy.

Perioperative Outcomes of Patients With Pancreatic Neuroendocrine Neoplasms in the Context of Different Body Composition Phenotypes

World Journal of Surgery, EarlyView.
Pancreatic neuroendocrine neoplasms (pNEN) are rare and heterogeneous tumors with increasing incidence. While surgical resection remains the only curative treatment, perioperative outcomes are influenced by patient‐related risk factors. Recent research highlights body composition (BC) as a prognostic marker in oncological and transplantation surgery ...

New PMCT multi‐indicator ossification standards for age estimation of the knee in modern Australian and North American children

Journal of Forensic Sciences, EarlyView.
Abstract Skeletal age estimation is crucial to medicolegal work, aiding subadult identification, and living age assessments in legal contexts. This study aims to document the ontogeny of knee skeletal indicators on post‐mortem computed tomography (PMCT), and quantify interpopulation variation between modern American and Australian children.

Impact of Hounsfield units on adjacent fracture risk after kyphoplasty

Brain and Spine
retrospective cohort study.This study aims to assess the utility of Hounsfield units (HU) derived from computed tomography (CT) scans as a predictive marker for the risk of adjacent fractures (AF) following kyphoplasty.In a retrospective analysis at a high-volume care hospital, 93 patients who underwent single-level kyphoplasty between January 2012 and

The Significance of Hounsfield Unit and Tumor Diameter in the Differentiation of Malignant and Benign Adrenal Masses [PDF]

Aim: The Hounsfield unit (HU) used in non-contrast computed tomography (CT) imaging can predict adrenal masses. In the literature, a HU measurement of >10 on non-contrast CT has been reported to have a wide range of sensitivity (33-72%) in detecting ...
