IntroductionWith the current Covid-19 pandemic, general wards have been converted into cohort for patients who are stable and ambulant. A 2-radiographer mobile radiography team is required to perform bedside Chest X-rays (CXR) these patients. Hospital guidelines require both radiographers be in full Personal Protective Equipment (PPE) throughout image acquisition process radiographic unit needs disinfected twice after each case. This affects efficiency of procedure an increase usage limited...
ABSTRACT Objective: to identify the participation of a multi-professional healthcare team in Radiation Protection Program, and describe implementation this program by staff working service. Method: qualitative, exploratory descriptive research, performed through semi-structured interview with professionals radiology service public hospital South Brazil. A sample 25 participants was considered sufficient after data saturation. The content analysis used, Atlas-Ti 7.0 software for treatment...

Typical distribution of exposure parameters in plain radiography is unknown Portugal. This study aims to identify that are being used the Lisbon area and compare collected data with European references [Commission Communities (CEC) guidelines]. The results show four examinations (skull, chest, lumbar spine pelvis), there a strong tendency using times above recommendation. X-ray tube potential values (in kV) below recommended from CEC guidelines. shows at local level (Lisbon region),...
Objectives: To develop a novel method for comparing radiation dose and image quality (IQ) to evaluate adult chest x-ray (CXR) imaging among several hospitals. Methods: CDRAD 2.0 phantom was used acquire images in eight hospitals (17 digital units) using local CXR protocols. IQ represented by figure inverse (IQFinv), measured analyser software. Signal noise ratio, contrast ratio conspicuity index were calculated as additional measures of IQ. Incident air kerma (IAK) solid-state dosimeter each...

Objetivos: comparar o Programa de Proteção Radiológica um hospital público na região Sul do Brasil com estabelecido legislação brasileira vigente e descrever cotidiano serviço. Metodologia: estudo qualitativo, exploratório descritivo desenvolvido por observação não participante análise documental Memorial Descritivo. Participaram 14 trabalhadores ocupacionalmente para-ocupacionalmente expostos. Adotada Análise Conteúdo para a dados. Resultados: evidenciaram-se inconsistências no necessidade...
Incidental findings on low-dose CT images obtained during hybrid imaging are an increasing phenomenon as technology advances. Understanding the diagnostic value of incidental along with technical limitations is important when reporting image results and recommending follow-up, which may result in additional radiation dose from further increase patient anxiety. This study assessed lesions incidentally detected acquired for attenuation correction two SPECT/CT systems. <b>Methods:</b> An...
