Dia, Amadou Sall. „Quantitative ultrasound imaging of human cortical bone“. Electronic Thesis or Diss., Sorbonne université, 2024. https://theses.hal.science/tel-04650855.
Der volle Inhalt der QuelleOsteoporosis is a disease characterized by a decrease in bone mass and an increase in porosity, weakening the bones and potentially leading to fragility fractures. Globally, one-third of women over the age of 50 and one-fifth of men aged over 50 will experience osteoporosis-related fractures, contributing to over 8.9 million fractures annually worldwide. Early detection and treatment can prevent these fractures. Several techniques have been developed to assess bone quality, with ultrasound emerging as a cost-effective, portable, and safe option. Ultrasound imaging of the cortex of long bones allows for the evaluation of bone quality by estimating cortical thickness and ultrasonic wave-speed, which are biomarkers of mechanical strength and fracture risk. However, challenges arise with increased cortical porosity in osteoporotic bone, making it difficult to detect the inner surface (endosteum) and limiting image quality. The aim of this study is to design an image reconstruction technique to enhance ultrasound images of cortical bone. This involves understanding the factors influencing image quality. Synthetic and experimental ultrasound datasets were generated to achieve this. The results demonstrate successful estimation of cortical thickness and ultrasonic wave-speed using ultrasound imaging for homogeneous cortical bone. In vivo estimation of wave-speed at the tibial cortex of healthy individuals achieved a precision of less than 3%. However, for degraded bones, increased cortical porosity and vascular pore size create speckle that obscures the visibility of the endosteal interface. A novel refraction-corrected specular beamforming algorithm was proposed to improve the visibility of the endosteal interface. Application of this algorithm to both ex vivo and in vivo datasets revealed enhanced visibility compared to traditional Delay-and-Sum (DAS) beamforming. This study provides a better understanding of factors affecting bone ultrasound image contrast and proposes considering scatterers as specular reflectors to enhance endosteal interface visibility. By evaluating the specularity of the endosteal interface, it becomes possible to potentially assess the roughness of the endosteum. This opens a way for designing new bone mechanical quality quantifiers. Bone ultrasound imaging shows promise in identifying and monitoring individuals with low cortical bone mechanical quality at risk of osteoporotic fracture

Der volle Inhalt der QuelleINTRODUCTION: The lack of optical correction was recently recognized as an important cause of low vision and it seems to be an easy problem to be solved with the use of spectacles. However, it is a complex problem from its diagnosis to treatment, which includes medical assistance searching and finding, and spectacles acquisition and use. PURPOSES: To determine the frequency of optical correction need; to determine the impact of the recall of those absent in the ophthalmologic service coverage and its causes; to check the previous ophthalmologic coverage; to check the use of the prescribed optical correction and causes to neglect the use of spectacles. METHOD: An analytical cross-sectional study was conducted. Students between 7 and 10 years old of public education from Guarulhos were screened and referred to ophthalmologic exam in the Eye to Eye Campaign 2006 and 2007. RESULTS: 40.197 students were screened and 11.741 (29,2%) were referred with suspicion of visual problems. The absenteeism in the first call was 42.5% and in the recall 62.2%. The Campaign reached 73.6% of the referred students. The recall expanded the project coverage in 16.1%. The lack of guidelines (parents did not receive notification or referral guide) was the most frequent reason (35.6%) provided by parents for the non attendance, followed by work (20.6%) and disease (12.4%). The need of glasses was not related to the attendance. For 60.2% of the students, it was the first opportunity for ophthalmological exam, whereby 27.3% searched but did not have access to a medical visit. Among the 1.379 students who had already performed an exam, 48.3% used the Public Health System and 1.029 received prescription of glasses in the previous exam. From those, 899 (87.4%) made their glasses and only 590 (57.3%) were wearing glasses on the day of the exam. From the donated spectacles in the Campaign, 84.7% of the students were using the donated optical correction after one year. The estimate of optical correction need within the studied population was 6.9%. CONCLUSIONS: The uncorrected refractive error was the main cause of low visual acuity among students. The Campaign was the first opportunity of ocular exam for most of them. A significant number of parents did not take their children for ophthalmological exams, even when facilities (access, free transportation, meal, two different opportunities of free exam over the weekend and spectacle donation) were offered. For 87.1% of the absenteeism cases, the difficulties could have been overcome via improved structuring of the first call. A recall is not recommended when financial resources are low
