Rectus abdominis and lumbar multifidus muscles evaluation by Ultrasound
R. A. Santos1, R. F. F. D. Barreiro2; 1Coimbra/PT 2Mealhada/PT

Aims and objectives:
Nowadays, postural changes affect all different age groups by the use of computers, cell phones or sedentary routines (1). A healthy spine needs a good posture, exercise and stretching (2). The promotion of a healthy spine and the prevention of postural deviations should be included and developed in[...]
Methods and materials:
30 young adults were submitted to an ultrasound evaluation of the rectus abdominis and multifidus lumbar muscles in rest and contraction and an angle measurement of the lumbar spine through a photometry equipment. They were divided in to groups: one of control and other with non-congenital posture. [...]
Results:
Using the SPSS v.20 software, it was shown that there were significant differences between the rest and contraction one muscle thickness and echo-intensity on both muscles. However, There were not significant differences between the two groups of participants and there was no correlation between the[...]
Conclusion:
Our study showed that there were significant differences between the muscle thickness values in rest and contraction, according to the results of Wittacker, et al. (2014) research (5). However, Kim, et al. (2006) defends that muscles trunk force and balance changes in trunk muscles may cause changes[...]

Vastus lateralis stiffness assessed with supersonic shear wave elastography
R. A. Santos1, P. Armada-da-Silva2; 1Coimbra/PT 2Lisbon/PT

Aims and objectives:
Ultrasound (US) has an important role in musculoskeletal (MSK) evaluation, allowing the study of muscle morphology and function (1). US elastography can also offer semi-quantitative and/or quantitative assessment of tissue stiffness providing relevant information about adaptations of muscle mechanic[...]
Methods and materials:
Sixteen young and active subjects, ten males, (mean ± SD; height: 1.69 ± 0.07 m, weight: 66.7 ± 8.1 kg, age: 20.06 ± 2.02 years) participated in this study. Data were collected in a single session. All contractions were performed on an isokinetic dynamometer (Biodex System 3, Biodex Medical Systems)[...]
Results:
The results demonstrated an acute increase of around 10% in VL’s shear modulus as a result of performing maximal isometric, concentric, and eccentric contractions. The shear modulus of the VL also increased when the knee moved from 10º to 50º and then to 90º flexion. Finally, a linear relationship b[...]
Conclusion:
By employing SSI, this study demonstrated that passive stiffness of the VL increases non-linearly with knee flexion as well as after maximal isometric and Ecc contractions, with the acute effect of Conc contractions on VL’s passive stiffness being less clear. A rather accurate relationship between t[...]

Image Quality Assessment in Chest Radiography
A. Moura1, L. P. Ribeiro1, A. M. Ribeiro1, A. F. Abrantes1, O. Lesyuk2, R. P. P. Almeida1; 1Faro/PT 2São Brás de Alportel/PT

Aims and objectives:
To assess image quality of chest radiograms based on quality control charts and to demonstrate the importance of implementing an image quality control system in the imaging departments.
Methods and materials:
A retrospective study was conducted in a public imaging department using a total of 860 random chest radiograms, divided in 43 samples with 20 exams each. The radiograms were analyzed according to a checklist based in the American College of Radiology guidelines to identify non-conformities in chest[...]
Results:
For every shift, the proportion of conformities and non-conformities (p chart), the total number of non-conformity exams (np chart) and the total number of non-conformities in each sample (c chart) were determined. For each chart, superior and inferior control limit, standard deviation and limit wa[...]
Conclusion:
Considering that this study was performed in a public hospital with emergency department, the high proportion of non-conformities in the patient positioning group might be explained with non-cooperative patients. The higher proportion of non-conformities by post-processing defects was identified i[...]

The contribution of Conventional Radiology in the evaluation of the complications of Total Knee Arthroplasty
F. Oliveira1, R. E. R. S. Lopes2, A. Monteiro3, A. M. P. Ribeiro4, G. Costa4; 1Ovar/PT 2Covilhã/PT 3Lisboa/PT 4Porto/PT

Learning objectives:
With this work we intend to demonstrate the contribution of conventional radiology in the evaluation of the femur-patellar component in total knee arthroplasty. As well as the importance of knowledge and the use of the most correct incidences for the evaluation of the components of the knee prosthes[...]
Background:
Complications of the femoral component are the most common cause of complaints after total knee arthroplasty. Obtaining adequate kinematics of the patellofemoral joint is crucial to achieve a good postoperative clinical result. The radiographic evaluations that are used to assess the patellofemoral [...]
Findings and procedure details:
In order to study the complications of knee arthroplasty, only AP incidences and profile are performed. These conventional radiographic incidences only allow the determination of leg alignment, however, to evaluate the rotation of the femoral component, CT or MRI are generally used, since they allow[...]
Conclusion:
Conventional radiology is a more accessible, economical, and low dose radiation imaging method for the patient, having a rather valid degree of acuity when compared to the disadvantages of the artifact caused by components of the knee prosthesis in the TC pictures. Conventional radiology demonstrat[...]

It is known that the issues related to [...]
Methods and materials:
Descriptive, correlational and comparative study. A 117 question self-applied questionnaire entitled “Hospital Employee Judgment System” grouped into 10 dimensions was used to assess job satisfaction of radiographers from public imaging departments. A total of 52 valid questionnaires were collected [...]
Results:
In a first phase, socio-demographic data was colleted with respect to their gender, age, home location, job location, economic status and educational level. In the second phase, the socio-professional data was collected, relating to issues that are also present in the measurement instrument, such [...]
Conclusion:
Professional satisfaction is a concept that has been defined in different ways over the years by several authors, in which the most frequent affirms that satisfaction is a synonym of motivation, attitude or positive emotional state, influencing the worker in his mental health, their behavior and pre[...]
