ABSTRACT
Essure es un dispositivo anticonceptivo permanente de inserción transcervical con histeroscopia. Se sitúa en las trompas a las que ocluye estimulando la fibrosis. Las técnicas para seguir a las pacientes son la radiografía simple, histerosalpingografía y ecografía, aunque los dispositivos se pueden identificar también incidentalmente con TC y RM. El seguimiento de Essure se basa en comprobar los criterios de posición adecuada y funcionamiento correcto (oclusión tubárica), y diagnosticar complicaciones. Las complicaciones más frecuentes son la perforación, migración (hacia la cavidad uterina o peritoneal), y fallo de la oclusión. La intravasación vascular es la causa más frecuente de error diagnóstico con la histerosalpingografía. Es importante que el radiólogo reconozca el dispositivo en las diferentes técnicas de imagen, los signos que indican que su situación y función son correctas y diagnosticar las complicaciones (AU)
Essure is a permanent birth control device that is inserted through the cervix by hysteroscopy. The device is placed in the fallopian tubes, where it causes occlusion by stimulating fibrosis. Patients can be followed up with plain-film X-rays, hysterosalpingography, and ultrasonography, although the devices can also be identified incidentally on CT and MRI. The follow-up of Essure is based on checking the criteria for appropriate positioning and correct functioning (tubal occlusion) and on diagnosing complications. The most common complications are perforation, migration (toward the uterine or peritoneal cavity), and occlusion failure. In hysterosalpingography, vascular intravasation is the most common cause of diagnostic error. Radiologists need to know how to recognize the device on different imaging techniques, how to check that it is correctly placed and functioning, and how to diagnose complications (AU)

La absorciometría con rayos X de doble energía (DXA o DEXA) es la técnica de elección para diagnosticar la osteoporosis y monitorizar la respuesta al tratamiento. Además, es útil para estudiar la composición corporal. En los últimos años han surgido nuevas aplicaciones como la morfometría vertebral, estudiando la columna en visión lateral, la integración de prótesis en ortopedia, o la lipodistrofia en los pacientes con infección por VIH, aunque su utilización en estos casos no está bien consolidada. En el estudio de la osteoporosis, densitometría es precisa y exacta. Para ello, es imprescindible optimizar cada etapa del proceso diagnóstico, cuidando la adquisición, el análisis de imágenes y la interpretación de los resultados. Por ello, para obtener la máxima utilidad para el clínico y el paciente, el radiólogo debe conocer la técnica, sus indicaciones y las dificultades. El objetivo de este artículo es revisar la DXA, haciendo hincapié en sus fundamentos, modalidades, metodología y aplicaciones clínicas (AU)
Dual-energy X-ray absorptiometry (DXA; DEXA) is the technique of choice to diagnose osteoporosis and to monitor the response to treatment. It is also useful for measuring body composition. In recent years, new applications have been developed, including vertebral morphometry through the study of the lateral spine, prosthesis integration in orthopedics, and lipodystrophy in HIV+ patients, although its use in these cases is not well established. DXA densitometry is accurate and precise. It is essential to optimize each step of the diagnostic process, taking care to ensure the best acquisition, image analysis, and interpretation of the results. Thus, to obtain the greatest utility from DXA, radiologists need to know the technique, its indications, and its pitfalls. This article reviews the fundamentals, modalities, methods, and clinical applications of DXA (AU)

La amiloidosis es un grupo de enfermedades de depósito, que se clasifican dependiendo del tipo de fibras que se acumulan y sus características.Puede afectar a cualquier órgano. La presentación clínica se manifiesta según los órganos o sistemas afectados.Presentamos una paciente con antecedentes de tiroiditis de Hashimoto y síndrome constitucional, que consultó por dolor abdominal. A la exploración se objetivó una masa palpable en mesogastrio. La TC demostró engrosamiento mural segmentario del colon con infiltración peritoneal adyacente y extensión a la raíz del mesenterio, con abundante ascitis.El diagnóstico histológico fue amiloidosis peritoneal (AU)
Amyloidosis is a group of deposition diseases that are classified according to the type of fibers accumulated and their characteristics.It can affect any organ. The clinical presentation depends on the organs and systems involved.We present the case of a patient with a history of Hashimoto's thyroiditis and systemic symptoms who presented with abdominal pain. Physical examination detected a palpable mass in the umbilical region. CT showed thickening of the wall of the colon with infiltration of the adjacent peritoneum and extension to the root of the mesentery with abundant ascites.The histological diagnosis was peritoneal AA amyloidosis (AU)
