To what degree is digital imaging reliable? Validation of femoral neck shaft angle measurement in the era of picture archiving and communication systems

Com o advento dos equipamentos digitais de diagnóstico médico, houve uma diminuição do uso de filmes emradiologia. Em contrapartida, o gerenciamento de imagens médicas (IMs) digitalizadas tornou-se uma tarefa crítica. Neste trabalho, apresentamos um protótipo, com base em tecnologias worldwide web (www), que realiza essa função. Ele contempla um servidor de IMs que possibilita a pesquisa e a recuperação dessas imagens armazenadas como arquivos digital imaging and communications in medicine (Dicom), além de receber requisições de serviços de equipamento sem aplicações compatíveis com esse padrão. As IMs podem ser visualizadas e manipuladas dentro de um navegador web (o cliente da aplicação) por meio de uma aplicação Java (applet). Tal abordagem oferece algumas vantagens em relação aos tradicionais sistemas de arquivamento e comunicação de imagens (picture archiving and communication systems [Pacs]), entre as quais a independência de plataformas e facilidade de instalação e de manutenção, a distribuição de dados e a integração com outros sistemas, dentro ou fora da instituição. Basta que se utilize a implementação de políticas de segurança. A simplicidade e a flexibilidade das tecnologias web viabilizam o uso dessa aplicação que provê recursos tanto para o gerenciamento quanto para a manipulação de IMs.

Picture Archiving And Communication

Background: PACS (Picture archiving and communication systems) and digital imaging (DI) has revolutionized radiology bringing about a paradigm shift in the way radiodiagnosis is perceived and practiced with a slew of benefits like elimination of the need for manual handling of films, helping in long term storage of digital images, easy transfer and retrieval of radiographic images. The objective of this study was to analyse the influence of PACS and digital imaging on the workflow in the radiology, performance of the radiographer and image storage and retrieval capabilities.Methods: It was a questionnaire-based study in which questions were asked to the radiographers working in our hospital at five different working sites. Each questionnaire was aimed to evaluate the effect of digital imaging on radiology workflow, improvement in the performance of radiographers, reduction in the work-related frustration levels due to use of digital imaging and finally the utility of digital imaging in image storage, query and retrieval.Results: Among the 50 questionnaires 41 were completed and retrieved. Among the respondents, 90.24% indicated that digital imaging has obviated the need for repeat examinations, 95.12% agreed with the fact that it resulted in the reduction of the number of reject images, 95.1% said it helped them in improving their performances, 92.6% of the respondents said they did not face any issue with its use and 95.1% of the participants agreed that the image query and retrieval could be accomplished in a hassle-free manner.Conclusions: The digital imaging technique not only improves the performance of the radiographers but also increases the workflow of the health care hospitals or clinics. The digital imaging reduces the number of rejected images thus reducing radiation exposure to the patients. Further, it is highly cost-effective and time-saving.

Routine radiographs are not cost effective in the intensive care unit (ICU) setting. Most published guidelines agree that radiographs are worthwhile after insertion of tubes or catheters, and in patients receiving mechanical ventilation. Otherwise, they are required only for change in the patient’s clinical status. Picture archiving and communication systems utilize digital imaging technology. They provide superior quality images, rapid image availability at multiple sites, and fewer repeat examinations, reducing both cost and patient radiation. Disadvantages of picture archiving and communication systems include expensive equipment and personnel required to keep them functioning. The majority of chest X-ray abnormalities in the ICU are best understood by paying careful attention to the initial appearance of the X-ray in relation to the patient’s onset of symptoms and the progression of abnormalities over the next few days.

Background: The femoral neck-shaft angle is the measurement of the angle formed between the oblique oriented neck with the vertical shaft and is an important anatomic measurement for the evaluation of biomechanics of hip. The neck shaft angle is important in surgeries that involve the neck of femur, Intertrochanteric fractures, slipped capital femoral epiphysis, and developmental dysplasia of hip. Different variation of neck shaft angle has been seen in different literature and all the orthopedic implants are designed according to the values of the western literature which is different from the Indian subcontinent.Methods: Pelvic radiographs of patients who presented to Accident and emergency care or the outpatient department were used in the study 110 patients radiographs were assessed in the study. There were 55 males and 55 females in our study. The mean age for males was 46.5 years and that for females was 43.2 years. The pelvis radiographs were studied for neck shaft angle .The measurements were performed bilaterally on the digital screen using the PACS (picture archiving and communication system) with handheld 360 degree goniometer.Results: The mean neck shaft angle in our study was129.26 degree for males and 126.62 degree for females .The overall mean neck shaft angle in 110 radiographs was 128.60 degree. Conclusions: We conclude that consideration of neck shaft angles in orthopedics surgery and designing of implant can give more angle options for the surgeons which can improve the overall prognosis of the patient.

The Impact

Background: While the influences of acetabular dysplasia and overcoverage on hip arthritis have been studied, the impact of femoral neck-shaft angle on hip arthritis is much more poorly understood. The purpose of this study is to determine if a relationship exists between neck shaft angle and the development of osteoarthritis, a better understanding of which would be useful to surgeons planning osteotomies about the hip. Methods: 533 cadaveric femora and acetabulae (1066 total) from the Hamann-Todd Osteological Collection (Cleveland, OH) were acquired. We measured true neck shaft angle using an AP photograph with the femoral neck parallel to the table. Femoral head volume to acetabular volume ratio, representing femoral head coverage, as well as femoral version were utilised. Correlation between neck shaft angle, femoral version, femoral head coverage and osteoarthritis were evaluated with multiple regression analysis. Results: The mean age and standard deviation was 56 ± 10 years. There were 64 females (12%) and 469 males. There were 380 Caucasians (71%) and 153 African-Americans. Mean femoral version was 11° ± 12° and mean true neck shaft angle was 127.7° ± 5.9° There was a strong correlation between age and arthritis (standardised beta 0.488, p < 0.001). There was a significant correlation between increasing true neck shaft angle and decreasing hip arthritis (standardised beta -0.024, p = 0.038). In the femoral head overcoverage subset, increasing true neck shaft angle was still significantly associated with decreasing hip arthritis (standardised beta −0.088, p = 0.018), although this relationship was not significant with femoral head undercoverage subset. Conclusions: With sufficient acetabular coverage, a relative increase in femoral neck shaft angle within the physiologic range is associated with decreased hip osteoarthritis. Clinical relevance: An understanding of the relationship between femoral neck shaft angle and hip osteoarthritis could be useful for surgeons planning pelvic or proximal femur osteotomies in children.
