| Abstract (English): |
Objective: To correlate the values of Hounsfield units reported in the liver with biochemical alterations in asymptomatic patients. Method: Longitudinal and retrospective study in patients who attended imaging studies and an abdominal tomography and blood chemistry laboratory studies were performed from January 2018 to August 2019. A 256 detector Revolution CT scanner was used (GE Milwaukee) and measurements were taken the reformatting station in Carestream RIS-PACS placing 1 cm in diameter ROIs in liver segments obtaining a total average of the liver density. The abdominal circumference was obtained at the body of L3 vertebrae in axial cuts, both measurements were integrated in the database. Results: 63 patients were analyzed, finding a statistically significant Pearson's correlation (p < 0.005). Analyzing the curved coordinates of the ROC of the UH and the presence or absence of metabolic syndrome, it was found that the value of 45.4 has greater utility with a sensitivity of 82% and a specificity of 72%. Conclusions: The value obtained from 45.4 Hounsfield units, we can use a simple tomography to identify patients with a high probability of not having metabolic alterations as a lower cut, and to reduce false positives for reports of steatosis.

Objetivo: Correlacionar los valores de unidades Hounsfield (UH) reportados en el hígado con las alteraciones bioquímicas en pacientes asintomáticos. Método: Estudio longitudinal y retrospectivo en pacientes a quienes se realizó tomografía de abdomen y estudios de laboratorios de química sanguínea de enero de 2018 a agosto de 2019. Se utilizó un tomógrafo General Electric Revolution (GE Milwaukee) de 256 detectores y una estación de reformateo en el sistema RIS-PACS Carestream. Se colocaron regiones de interés circulares de 1 cm de diámetro y se realizó un promedio total que se integró a la base de datos. La medición del perímetro abdominal se obtuvo a nivel de L3 en un corte axial estricto. Resultados: Se analizaron 63 pacientes y se encontró una correlación de Pearson estadísticamente significativa (p < 0.005). Al analizar las coordenadas en curva ROC de cruce de las UH y la presencia o no de síndrome metabólico se encontró que el valor de 45.4 tiene la mayor utilidad, con una sensibilidad del 82% y una especificidad del 72%. Conclusiones: El valor obtenido de 45.4 UH puede ayudarnos en una tomografía simple para poder identificar como corte inferior a pacientes con alta probabilidad de no presentar alteraciones metabólicas, y reducir los falsos positivos para reportes de esteatosis.
