Esta experiencia docente presenta una articulación pedagógica entre la cátedra de Ingeniería de Software de la Universidad Siglo 21 y el sexto año de nivel secundario del Instituto Domingo Faustino Sarmiento de La Calera. El objetivo central es fomentar vocaciones tecnológicas y …

Automated volumetric MRI quantification of body fat and skeletal muscle in the UK Biobank: technical validation against expert manual segmentations and comparison with single-slice techniques

M A Nowak, Luis Núñez, CJ Hill, Tim Pagliaro et autres

OBJECTIVES: The escalating global incidence of obesity, cardiometabolic disease and sarcopenia necessitates reliable body composition measurement tools. MRI-based assessment is the gold standard, with utility in both clinical and drug trial settings. This study aims to validate a new automated volumetric MRI …

Automatic Couinaud segmentation using AI and pictorial representation landmarking

Luis Núñez, Paul Aljabar, Sir Michael Brady

OBJECTIVES: Delineating the Couinaud segments is a critical component of liver surgery and monitoring that has traditionally relied on labor-intensive methods that are prone to variability. While fully or semi-automatic methods exist, they generally lack accuracy or require extensive post-processing or corrections …

Repeatability, reproducibility, and observer variability of body composition assessment with single-slice lumbar MRI

Magdalena Nowak, Luis Núñez, CJ Hill, Tom R. Davis et autres

The single-slice MRI at the third lumbar vertebra (L3) offers an efficient way to assess body composition but evidence on the reliability of this method is scarce. This study evaluates the accuracy and precision of the single-slice L3 method for adipose and …

Assessing the performance of AI-assisted technicians in liver segmentation, Couinaud division, and lesion detection: a pilot study

Luis Núñez, Carlos Ferreira, Amirkasra Mojtahed, Hildo J. Lamb et autres

BACKGROUND: In patients with primary and secondary liver cancer, the number and sizes of lesions, their locations within the Couinaud segments, and the volume and health status of the future liver remnant are key for informing treatment planning. Currently this is performed …

Unraveling response to temozolomide in preclinical GL261 glioblastoma with MRI/MRSI using radiomics and signal source extraction

Luis Núñez, Enrique Romero, Margarida Julià‐Sapé, María J. Ledesma‐Carbayo et autres

Glioblastoma is the most frequent aggressive primary brain tumor amongst human adults. Its standard treatment involves chemotherapy, for which the drug temozolomide is a common choice. These are heterogeneous and variable tumors which might benefit from personalized, data-based therapy strategies, and for …

Interpreting response to TMZ therapy in murine GL261 glioblastoma by combining Radiomics, Convex-NMF and feature selection in MRI/MRSI data analysis

Luis Núñez, Margarida Julià‐Sapé, Enrique Romero, Carles Arús et autres

Machine learning (ML) methods have shown great potential for the analysis of data involved in medical decisions. However, for these methods to be incorpored in the medical pipeline, they must be made interpretable not only to the data analyst, but also to …

Definition of internal target volumes based on planar X‐ray fluoroscopic images for lung and hepatic stereotactic body radiation therapy. Comparison to inhale/exhale CT technique

D. Sevillano, Luis Núñez, Margarita Chevalier, F. Garcı́a‐Vicente

PURPOSE: To compare tumor motion amplitudes measured with 2D fluoroscopic images (FI) and with an inhale/exhale CT (IECT) technique MATERIALS AND METHODS: Tumor motion of 52 patients (39 lung patients and 13 liver patients) was obtained with both FI and IECT. For …
