Diagnosis of pre-sarcopenia from a single selectional crosscut at C3 region, using CT scans before radiotherapy
2019
espanolProposito: el proposito de este estudio fue diagnosticar la presarcopenia en pacientes con cancer que no disponen de imagenes por tomografia computarizada (TC) a nivel abdominal mediante un metodo novedoso basado en cortes a nivel cervical. Material y metodos: se analizaron y se compararon mediante unidades la masa muscular y la masa muscular esqueletica en 37 pacientes con cancer de pulmon y neoplasias del aparato digestivo superior que incluian cortes en la TC de planificacion a nivel de C3 y L3. La presarcopenia se identifico de acuerdo con los puntos de corte establecidos actualmente: ≤ 41 cm2/m2 para mujeres, ≤ 43 cm2/m2 en hombres con un IMC ≤ 25 kg/m2 y ≤ 53 cm2/m2 en hombres …
Measurement of body composition in cancer patients using CT planning scan at the third lumbar vertebra
2019
Objective: the main objective was to assess body composition in terms of skeletal muscle index (SMI), myosteatosis, visceral adipose tissue (VAT), subcutaneous adipose tissue (SAT), and intermuscular adipose tissue (IMAT) as an adjunct of information provided by radiotherapy CT planning scan. Material and methods: a sample of 49 patients with lung and digestive cancers underwent a CT scan for radiotherapy treatment, which included measurements at the L3 region. Images were analyzed with a radiotherapy contouring software, using different Hounsfield Unit (HU) settings. Cross-sectional areas (cm2) were automatically computed by summing tissue pixels and multiplying by pixel surface area. Low …
