ObjetivoEl objetivo de esta revisión fue evaluar la capacidad diagnóstica de la PET/RM simultánea en oncología, comparándola con la de la PET/TC, basándonos en la evidencia disponible.Material y métodosSe realizó una búsqueda sistemática en las bases de datos Medline y Embase hasta el 21 de enero de 2016, para identificar artículos clínicos originales que realizasen un análisis comparativo entre PET/RM simultánea y PET/TC en pacientes oncológicos.ResultadosSe obtuvo un total de 57 artículos, distribuidos por enfermedades del siguiente modo: carcinoma de cabeza y cuello (5), pulmón y nódulos pulmonares (13), carcinoma colorrectal (1), lesiones hepáticas (2), incidentalomas abdominales (1), tumores neuroendocrinos (2), carcinoma de tiroides (2), carcinoma de mama (3), tumores ginecológicos (2), carcinoma de próstata (4), linfoma (2), mieloma múltiple (1), metástasis óseas (3), tumores intracraneales (2), oncología pediátrica (1) y neoplasias diversas (13). En la mayoría de las enfermedades oncológicas, el rendimiento diagnóstico de la PET/RM simultánea fue similar o incluso superior al de la PET/TC. Sin embargo, la PET/TC fue superior en la detección de pequeños nódulos pulmonares.ConclusiónLa PET/RM simultánea en oncología es factible, obteniendo resultados al menos equiparables a los de la PET/TC, con menor exposición a radiaciones ionizantes. No obstante, la evidencia disponible aún es limitada, y son necesarios estudios que incluyan a un mayor número de pacientes y neoplasias para establecer las indicaciones de la PET/RM e identificar los protocolos adecuados a cada enfermedad.ObjectiveThe aim of this review was to evaluate the diagnostic performance of simultaneous PET/MRI in oncology compared with that of PET/CT, based upon the available evidence.Material and methodsA systematic search was performed in the Medline and Embase databases to identify original clinical articles published up to 21 January 2016, in order to compare simultaneous PET/MRI and PET/CT in oncology patients.ResultsA total of 57 articles were obtained that included various diseases: head and neck cancer (5), lung cancer and lung nodules (13), colorectal cancer (1), liver lesions (2), abdominal incidentalomas (1), neuroendocrine tumours (2), thyroid carcinoma (2), breast cancer (3), gynaecological cancer (2), prostate cancer (4), lymphoma (2), multiple myeloma (1), bone metastases (3), intracranial tumours (2), paediatric oncology (1) and various tumours (13). Diagnostic performance of simultaneous PET/MRI was similar or even better to that of PET/CT in most oncological diseases. However, PET/CT was superior for small lung nodule detection.ConclusionSimultaneous PET/MRI in oncology is feasible, performing at least equally as well as PET/CT, with lower radiation exposure. However, available evidence is still limited. Studies including more patients and tumours are needed to establish PET/MRI indications and to identify appropriate protocols for each disease.
