Resumen
18F-FDG PET/CT auxiliares en el diagnóstico de la enfermedad en adultos
Área de la Ciencia:
- Reumatología y Medicina Nuclear
Sus antecedentes:
- La enfermedad de Still de inicio en adultos (AOSD) es una condición inflamatoria sistémica rara.
- AOSD a menudo se presenta como fiebre de origen desconocido (FUO), complicando el diagnóstico.
- Los desafíos de diagnóstico requieren modalidades avanzadas de imágenes.
Objetivo del estudio:
- Revisar sistemáticamente la utilidad de diagnóstico del 18F-FDG PET/CT en el AOSD.
- Evaluar el papel del 18F-FDG PET/CT en la diferenciación de la DEAO de otras afecciones.
Principales métodos:
- Revisión sistemática que se adhiere a las directrices de PRISMA.
- Buscado en las bases de datos de PubMed, EMBASE y Ovid hasta diciembre de 2022.
- Se incluyeron 54 estudios (545 pacientes) que incluían informes de casos, series y ensayos observacionales.
Principales resultados:
- 18F-FDG PET/CT se utilizó en el 85% de los casos revisados, principalmente para el diagnóstico.
- Se observaron valores elevados de absorción estandarizada (SUV) en médula ósea, bazo y hígado.
- Se observaron frecuentemente patrones de hipermetabolismo difuso en estos órganos.
Conclusiones:
- 18F-FDG PET/CT es un valioso complemento para el diagnóstico de AOSD, especialmente en casos de FUO.
- Los patrones de absorción característicos en órganos específicos pueden apoyar el diagnóstico de AOSD.
- La biopsia sigue siendo crucial para excluir imitaciones neoplásicas.

Positron Emission Tomography
5.4K
Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...

Radiological Investigation III: Pulmonary Angiogram and PET Scan
167
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
