This book was released on 2019 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this thesis was to develop an artificial intelligence algorithm to classify patient specific bone density from DICOM images acquired from orthodontic radiographic scans and to develop an osteoporosis screening tool. Osteoporosis is a degenerative disease that results in weakened, brittle bones; unfortunately, this disease presents no outward symptoms until a bone is fractured. The goal of this research was to develop a method to assist in the early diagnosis of this disease using routine dental and orthodontic scans. Bone density in this thesis was approximated by pixel intensities from patient DICOM images. Individual cephalometric patient scans from an orthodontist were read into a custom MATLAB algorithm, which extracted points from the patient0́9s alveolar bone and determined the pixel intensity as an indicator for bone density. The alveolar (anterior mandible) bone was analyzed due to a correlation between tooth loss and osteoporosis documented in the literature. The intensity values of these pixels were averaged together as one global value for each patient. By comparing these global values versus age for 32 patients, a correlation between patient age and bone density was evident: as patients increase in age past 35 years, their bone density decreases, with different trend characteristics for men versus women. The results of this thesis provide a basis for the creation of a commercialized graphical user interface to aid medical professionals in the early detection of decreasing bone density in their patients.

Download or read book Image Analysis Techniques for Whole Bone Assessment written by Timothy G. Perk and published by . This book was released on 2017 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this dissertation, we developed and applied image processing tools that can perform automated quantitative assessment of whole bone images. We developed Quantitative Total Skeleton Imaging (QTSI) for assessing whole bone. QTSI can be performed on anatomical CT images (QTSI(CT)) or on functional PET/CT images (QTSI(PET/CT). QTSI quantifies both image intensity and heterogeneity of bone on a regional, as well as whole skeleton, level and can perform image-based response assessment of patients on a voxel-level. We developed a method to create whole skeleton statistical appearance models, which can provide population average and ranges of expected bone intensity for each voxel within the bone, which for CT is bone density and for PET is bone activity. Using statistical appearance models of average and ranges of healthy bone intensity, QTSI(CT) and QTSI(18F-NaF PET/CT) were used to quantify healthy bone density with CT and healthy bone turnover with 18F-NaF PET/CT, respectively. We developed Quantitative Total Marrow Imaging (QTMI(PET/CT)) for assessing the bone marrow. We created a quantitative reference of healthy bone marrow proliferation, providing expected values of healthy bone marrow activity for each bone region in the skeleton. QTMI(18F-FLT PET/CT) analysis was demonstrated in two patients with acute myeloid leukemia (AML). Both uptake and response metrics were found to differentiate patient response. We developed Quantitative Total Bone Imaging (QTBI(PET/CT)) for assessing patients with multiple bone lesions. To improve detection of lesions in QTBI(18F-NaF PET/CT), we developed a Statistically Optimized Regional Thresholding (SORT) method to optimize lesion detection. We created disease distribution models that represent distributions of benign and malignant bone lesions. We developed a machine learning tool for automated classification of definite benign vs definite malignant lesions (AUC=0.95). This model was trained on different physicians and could accurately predict (AUC=0.93-0.94) how each physician classified lesions. With these tools we can comprehensively assess bone disease by identifying if patients have abnormalities within the bone, automatically identifying the location of abnormal regions of bone, assessing if the abnormalities are in areas of higher risk of certain bone diseases, classifying lesions as benign or malignant, and longitudinally monitoring lesions over the course of treatment.

Download or read book Radiology of Osteoporosis written by Stephan Grampp and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to the aging population in the Western world, osteoporosis has become a major problem which is of interest to several medical disciplines: not only radiologists but also gynecologists, endocrinologists, rheumatologists, and orthopedic surgeons are involved in the management of this widespread condition. Functional imaging is becoming rapidly an important area of diagnostic radiology. Imaging of osteoporosis is another application of this recent addition to the armory of radiology. It is important that radiologists should be fully aware of the range of diagnostic modalities-conventional radiologic methods, dual X-ray absorptiometry, quantitative computed tomography, quantitative ultrasound, magnetic resonance imaging, etc. -that are now available for the diagnosis and the follow-up of osteoporosis, and know how to apply these sophisticated methods in daily clinical practice. Dr. S. Grampp is a radiologist with a longstanding interest in osteoporosis, and his previous publications on this condition are internationally known. He has been very successful in engaging several outstandingly qualified experts to contribute to the indi vidual chapters of this superb book, which provides a omprehensive c overview of our current knowledge of osteoporosis. I am confident that this volume will meet with great interest from radiologists and all other clinicians involved in the care of patients with osteoporosis and will encounter the same success as many previous volumes in this series.

Download or read book Registries for Evaluating Patient Outcomes written by Agency for Healthcare Research and Quality/AHRQ and published by Government Printing Office. This book was released on 2014-04-01 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: This User’s Guide is intended to support the design, implementation, analysis, interpretation, and quality evaluation of registries created to increase understanding of patient outcomes. For the purposes of this guide, a patient registry is an organized system that uses observational study methods to collect uniform data (clinical and other) to evaluate specified outcomes for a population defined by a particular disease, condition, or exposure, and that serves one or more predetermined scientific, clinical, or policy purposes. A registry database is a file (or files) derived from the registry. Although registries can serve many purposes, this guide focuses on registries created for one or more of the following purposes: to describe the natural history of disease, to determine clinical effectiveness or cost-effectiveness of health care products and services, to measure or monitor safety and harm, and/or to measure quality of care. Registries are classified according to how their populations are defined. For example, product registries include patients who have been exposed to biopharmaceutical products or medical devices. Health services registries consist of patients who have had a common procedure, clinical encounter, or hospitalization. Disease or condition registries are defined by patients having the same diagnosis, such as cystic fibrosis or heart failure. The User’s Guide was created by researchers affiliated with AHRQ’s Effective Health Care Program, particularly those who participated in AHRQ’s DEcIDE (Developing Evidence to Inform Decisions About Effectiveness) program. Chapters were subject to multiple internal and external independent reviews.
Download or read book Osteosarcopenia Bone Muscle and Fat Interactions written by Gustavo Duque and published by Springer Nature. This book was released on 2019-11-06 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited work presents the most current evidence on osteosarcopenia from bench to bedside, which is expected to facilitate the understanding of this syndrome and to develop preventive and therapeutic strategies. With our aging population, chronic diseases such as osteoporosis and sarcopenia are becoming highly prevalent. Fortunately, our understanding of the bone and muscle interactions has increased in recent years. This has allowed to the coining of the term osteosarcopenia to describe a syndrome in which these two diseases overlap. This overlap between osteoporosis and sarcopenia has major negative effects not only on our older adults but also on health systems worldwide. Readers will find a highly translational approach that starts with a summary of recent discoveries on stem cells biology, muscle and bone interactions – including the role of local bone and muscle fat – followed by comprehensive reviews on myokines (i.e. myostatin), osteokines (i.e. osteocalcin) and adipokines (i.e. interleukins) as major players and determinants of bone and muscle loss with aging. In addition, the role of sex steroids (i.e. estrogens, androgens), and calciotropic hormones (i.e. parathyroid hormone, vitamin D) in the pathogenesis of this syndrome is also reviewed. Moreover, using practical diagnostic and therapeutic tips, this book summarizes the clinical characteristics of osteosarcopenic patients thus facilitating the diagnosis and treatment of this syndrome in clinical practice. Finally, the book presents the case for the Falls and Fractures Clinic as the optimal model of care for this syndrome, aimed to avoid fragmentation and optimize osteosarcopenia care, and simultaneously prevent falls and fractures in older persons. This book offers relevant information on the mechanisms of osteosarcopenia, and a practical guide on how to identify and treat this geriatric syndrome and its adverse outcomes, which are dramatically affecting our aging population. The work is written by leaders in the field and is especially suited not only to any researcher in the musculoskeletal arena but also to medical specialists and allied health professionals involved in the care of older persons.
