Precisión y eficiencia de un software automático para cuantificar los volúmenes del ventrículo izquierdo por cardio-resonancia magnética (CRM)
Palabras clave:
volúmenes del ventrículo izquierdo, volumen del ventrículo izquierdo, poster, seram, cardio-resonancia magnética, softwareResumen
Objetivos
Evaluar la precisión, fiabilidad, y eficiencia temporal de un software de segmentación del ventrículo izquierdo totalmente automatizado recientemente comercializado, para calcular los volúmenes y función del VI, comparado con la segmentación manual convencional.
Material y métodos
Este estudio de cohortes consistió en 67 individuos consecutivos con enfermedad isquémica conocida o sospechada, a los que se les indicó una RM cardíaca de estrés con adenosina. Todos los pacientes estaban estables y en ritmo sinusal en el momento de la exploración.
Los pacientes con claustrofobia severa, objetos no compatibles con RM, portadores de marcapasos/DAI e insuficiencia renal (filtrado glomerular < 30 ml/min) fueron excluidos. A los pacientes se les indicó evitar alimentos y bebidas con cafeína en las 24h anteriores a la exploración. El comité institucional
aprobó el protocolo del estudio.
