ABSTRACT
El cuadro clínico de la enfermedad conocida como COVID-19, causada por el nuevo coronavirus SARS-CoV-2 puede variar desde síntomas respiratorios leves hasta una insuficiencia respiratoria severa. Sus efectos en el organismo, especialmente la afección pulmonar, pueden ser visualizados a través de los estudios por imágenes. Si bien el diagnóstico de certeza se confirma mediante la reacción en cadena de la polimerasa con transcriptasa reversa (RT-PCR), los estudios por imágenes, especialmente la radiografía y la tomografía computarizada (TC) de tórax, desempeñan un papel fundamental en el manejo clínico de estos pacientes. Conocer su utilidad, casos de uso y hallazgos esperables brinda herramientas para el equipo de salud, temas que serán abordados en esta actualización y guía práctica. (AU)
The clinical pattern of the disease known as COVID-19, caused by the new coronavirus SARS-Cov-2 can range from mild respiratory symptoms to severe respiratory failure. Its effects on the body, especially the lung condition, can be visualized through imaging studies. While the diagnosis of certainty is confirmed by reverse transcriptase-polymerase chain reaction (RT-PCR), imaging studies, especially chest xray and computed tomography (CT), play a critical role in the clinical management of these patients. Knowing their usefulness, use cases, and expected findings provides tools for the health care team, topics that will be addressed in this update, and practical guide. (AU)

BACKGROUND: Diagnostic radiology residency programs pursuits as main objectives of the development of diagnostic capabilities and written communication skills to answer clinicians' questions of referring clinicians. There has been also an increasing focus on competencies, rather than just education inputs. Then, to show ongoing professional development is necessary for a system to assess and document resident's competence in these areas. Therefore, we propose the implementation of an informatics tool to objectively assess resident's progress in developing diagnostics and reporting skills. We expect to found decreased preliminary report-final report variability within the course of each year of the residency program. RESULTS: We analyzed 12,162 evaluations from 32 residents (8 residents per year in a 4-year residency program) in a 7-month period. 73.96% of these evaluations belong to 2nd-year residents. We chose two indicators to study the evolution of evaluations: the total of discrepancies over the total of preliminary reports (excluding score 0) and the total of likely to be clinically significant discrepancies (scores 2b, 3b, and 4b) over the total of preliminary reports (excluding score 0). With the analysis of these two indicators over the evaluations of 2nd-year residents, we found a slight decrease in the value of the first indicator and relative stable behavior of the second one. CONCLUSIONS: This tool is useful for objective assessment of reporting skill of radiology residents. It can provide an opportunity for continuing medical education with case-based learning from those cases with clinically significant discrepancies between the preliminary and the final report.
ABSTRACT
We present the initial results of a novel hybrid scanning-based technique that combines pneumo-computed tomography (PNCT) with positron emission tomography (PET) using 2-(fluorine-18) fluoro-2-deoxy-D-glucose (FDG). We denominate it pneumo-PET-CT. The focus of our discussion will be on the description of the pneumo-PET-CT technique and the interpretation criteria with emphasis on its benefits and applications in the presurgical and postneoadjuvant therapy evaluation of esophageal, esophagogastric junction (EGJ), and gastric tumors.
