Osteoporosis is a major cause of morbidity and mortality around the world and is a silent disease characterized by low bone strength that results in an increased risk of fracture. The benefits of being physically active in advanced ages to reduce the loss of bone mineral density (BMD) and improve functional capacities are well known. Quantitative u...

Purpose: The aim of this study was to design an aluminium-based filter to reduce the anode heel effect in lumbar spine radiographs. Methods: Initially, lumbar spine examinations were observed in a public imaging department to determine the standard exposure parameters. Then, the characterization of the anode heel effect was made using the Unfors Xi...

Introduction: Evidence based radiography (EBR) is the logical development of evidence based practice applied to radiography. The aim of this study was to investigate the opinion of a cohort of Portuguese radiographers in Southern Portugal working in public hospitals regarding evidence based practice (EBP), namely about the levels of knowledge abou...

The purpose of this chapter is to discuss the influence of school education on the formation of professional identity of radiology professionals. The research approach selected was based on a bibliographic review regarding the concepts involving professional identity and the transfer of knowledge at the school level, and the methods utilized to tra...

Purpose To establish an understanding of patient safety within radiography education across Europe by surveying higher education institutions registered as affiliate members of the European Federation of Radiographer Societies (EFRS). Method An online survey was developed to ascertain data on: programme type, patient safety definitions, relevant sa...

Objective To measure the scattered radiation dose at different positions simulating hip surgery. Materials and Methods We simulated fluoroscopy-assisted hip surgery in order to study the distribution of scattered radiation in the operating room. To simulate the patient, we used a anthropomorphic whole-body phantom, and we used an X-ray-specific de...

With this review article, we intend to demonstrate the importance of Computerized Tomography (CT) in healthcare quality and safety. The concept of safety in CT is wider than for general healthcare. Safe healthcare provided using CT must include diagnostic image quality and reliability, as this is the only way to ensure diagnostic accuracy. The imag...

Objective To compare the capacity of mammography, sonoelastography, B-mode ultrasonography and histological analysis to differentiate benign from malignant breast lesions. Materials and Methods A total of 12 histopathologically confirmed breast lesions were documented. The lesions were assessed by means of mammography, B-mode ultrasonography and s...

Purpose: To evaluate the importance that radiographers give to quality control programs, radiological protection and the verification of radiological protection criteria. Methods and Materials: A 30-item quality control assessment and radiological protection questionnaire was applied to radiographers working on public hospitals and healthcare centr...

Purpose: Applying control charts to demonstrate the importance of implementing a radiological imaging quality control system. Methods and Materials: Research conducted in a public hospital comprising a total of 1110 randomly selected exams (640 chest studies, 340 abdominal studies and 130 foot studies) grouped in 37 samples, each one with 30 exams....

Themain objective of this research was to determine if the diagnostic image, acquired by CT scan, meets the quality criteria previously established for head CT exams. A total of 360 Head Computed Tomography exams were analyzed, using a checklist. For data collection, quality criteria were created, organized into four criteria groups, consisting of...

Purpose: This study aimed to evaluate the radiographers’ knowledge on evidencebased radiology, how they conduct their research on this thematic and how they apply it. Methods and Materials: A self-applied questionnaire made by Ahonen & Liikanen (2010) to assess evidence-based radiology was applied to radiographers working in public hospitals and he...

Introduction: Fatty liver (steatosis of the liver) is one of the most common reasons people have abnormal liver blood tests. Excessive alcohol intake also causes fatty liver because of the way alcohol is burned in the liver. Objectives: Assessement of fatty liver using an abdominal ultrasound exam and its relation to body mass composition. Methods:...

Image Quality Control is an important factor that contributes to the improvement of patient care and overall diagnostic accuracy. Our purpose was to elaborate Quality Control Charts and demonstrate the importance of image quality control in a radiology department. A total of 37 random samples, composed of 30 x-ray exams each, were selected and anal...

Results: A great percentage of women reveal low BMD (46%), 9% of which are classified as osteoporotic. In men 28% were classified as osteopenic and 5% as osteoporotic. The BMD distribution by age group, for both genders, is consistent with our bibliographic reviews regarding the increased number of cases with low BMD in women with more than 50 year...

The application of management tools to the radiology service can represent an important role in the improvement of the procedures executed, namely those of a digital mammography room, once by the efficient control of the processes, it´s possible to reach the goals of the radiology service. In this area, the audits, as well as their approach execute...
