Radiology volunteers to support a breast cancer screening program in Peru: Description of the project, preliminary results, and impressions.

Breast cancer is the second most common cancer in Peruvian women. Due to limitations in national breast cancer screening programs, especially in rural areas, more than 50% of cases of breast cancer in Peru are diagnosed in advanced stages. In collaboration with a local clinic registered as a nongovernmental organization (CerviCusco), RAD-AID International aims to create a sustainable diagnostic structure to improve breast cancer screening in Cuzco. With the support of local, national, and international partners that have collaborated in analyzing radiological resources, raising awareness in the population, acquiring equipment, training clinical staff, and building referral networks, our teams of radiologists, included in the RAD-AID team, have participated in training CerviCusco staff in breast ultrasound, thus enabling additional training for radiology residents through a regulated international collaboration.

Voluntariado radiológico para apoyar un programa de detección precoz del cáncer de mama en Perú: descripción del proyecto, presentación de los primeros resultados e impresiones / Radiology volunteers to support a breast cancer screening program in Peru: description of the project, preliminary results, and impressions

El cáncer de mama es el segundo cáncer más frecuente en las mujeres peruanas. Las limitaciones de los programas nacionales de detección precoz, sobre todo en las regiones rurales, propician que más del 50% de los nuevos casos de cáncer de mama en Perú se diagnostiquen en estadios avanzados. RAD-AID Internacional, en colaboración con una clínica local registrada como organización no gubernamental (CerviCusco), pretende crear una estructura diagnóstica sostenible que mejore el cribado del cáncer de mama en Cuzco. Para ello se ha contado con socios locales, nacionales e internacionales que han colaborado en el análisis de recursos radiológicos, la concienciación de la población, la adquisición de equipamiento, el entrenamiento clínico y las redes de referencia. Nuestros equipos de radiólogos, incluidos en el equipo RAD-AID, han participado en la capacitación ecográfica del personal de CerviCusco, permitiendo una formación adicional a los residentes de radiología gracias a una colaboración internacional reglada.(AU)

Follow-up in head and neck cancer. What the radiologist must know. / Seguimiento del cáncer de cabeza y cuello tratado. Lo que el radiólogo debe conocer.

The management of patients with head and neck cancer implies a multidisciplinary treatment with surgery, radiotherapy and chemotherapy. Imaging is crucial in their follow-up, especially when the tumor recurrence is not clinically evident. Radiologically distinguishing post-treatment changes from a tumor recurrence is a challenge due to the anatomical alteration due to surgical techniques and their reconstructions, radiotherapy treatment and chemotherapeutic guidelines. The differential diagnosis must include the possible complications derived from radiotherapy (mucosal necrosis, osteoradionecrosis, vasculopathy, cerebral radionecrosis) and surgery (wound infections, flap necrosis, fistulas,...). A wide knowledge of the expected findings of multimodal treatment and its complications is essential for an accurate diagnosis of tumor recurrence. Finally, choosing the appropriate image study and having a baseline post-treatment study is also relevant for a suitable radiological control.

Is positive oral contrast material necessary for computed tomography in patients with suspected acute abdomen? / Ante la sospecha de abdomen agudo, ¿es necesario el contraste oral positivo en la tomografía computarizada?

The number of computed tomography studies done in emergency departments has increased substantially, and with this increase the controversy about whether positive oral contrast agents are necessary in all patients has also grown. The great image quality provided by multidetector computed tomography scanners, the increase in intraabdominal fat (as a natural element that provides contrast for separating the bowel loops) related with the increased prevalence of obesity in the population, and the potential drawbacks associated with the use of high-density oral contrast agents argue against the generalized us of these agents. This article aims to evaluate the effects of omitting the use of this type of oral contrast material for computed tomography examinations required in the emergency department for suspicion of acute abdominal pathology through an efficient literature search among recent publications.
