Abstract Medical x-ray imaging is used to visualise patients’ anatomical structures and in some cases their physiology. X-rays are ionizing radiation, thus their use needs to be optimised, as stochastic effects are assumed to increase linearly with the exposure dose. Imaging protocols need to be optimised to a radiation dose level that follows the as low as reasonably achievable principle without compromising the diagnostic value of the image. Different methods can be used to help in the optimisation process, such as simulations, radiation dose and image quality assessments with dosimeters and

Abstract This dissertation is a pioneering effort in a project to document, preserve and study the human remains found beneath old Northern Finnish churches. These remains have spontaneously mummified as a result of the early modern elite’s practice of burying under church floors. The main subject of the study is an early 17th-century Vicar of the Kemi parish, Nikolaus Rungius, and his mummified remains. His mummy that still is an important tourist attraction and a popular character in local lore, has a unique history as it has been exhibited since the 18th-century. The computed tomography sca

Tutkimuksessa tutkittiin Oulun Yliopistollisen sairaalan päivystyksessä 07/2010–7/2011 tietokonetomografialla kuvattuja tapaturmapotilaita. Tutkimuksen tarkoituksena oli selvittää kuinka suuressa osassa kuvauksia tuli diagnostisesti merkittäviä löydöksiä. Kuvantamislöydöksiä verrattiin erilaisiin muuttujiin, kuten ikään ja kuvausindikaatioon sekä ISS-traumaluokitukseen. Tutkielman aineisto kerättiin trauma TT tutkimuskoodin perusteella ja tilastoitu SPSS-ohjelman avulla.

Abstract Osteoarthritis (OA) is a heterogenic joint disease significantly affecting the quality of life of a patient, causing pain and disability. OA causes degenerative changes to the structure and composition of articular cartilage and subchondral bone. Currently, effective treatments for OA are limited, partly due to limitations in defining the imaging biomarkers of early OA. Improvement of imaging modalities in OA research and clinical setup is a requirement for quantitating early OA-related tissue features. In the clinical and preclinical setup, computed tomography (CT) enables imaging of

Abstract This thesis evaluated the factors affecting bone flap survival and bone flap resorption after primary cranial reparation surgery, cranioplasty, conducted to repair a cranial bone defect with an autologous cryopreserved bone flap. Emphasis is put on the predictors, progression, and definition of an important yet poorly understood postoperative complication, bone flap resorption. Study I assessed the rates and predictors of bone flap removal and bone flap resorption in a Finnish retrospective multicentre setting. 40% of patients developed complications of whom half required bone flap re

Abstract Osteoarthritis (OA) is the commonest joint disease in the world, and it has a major socioeconomic impact. OA causes progressive degenerative changes in the composition and structure of articular cartilage and subchondral bone. Clinical diagnosis of OA is based on physical examination and qualitative evaluation of changes on plain radiographs. Current clinical imaging methods are subjective or insensitive to early OA changes. Therefore, new methods are needed so as to quantify composition of the cartilage and characteristics of the subchondral bone. The aim of this thesis was to evalua

Abstract In brain surgery the operated region is often removable pathological tissue or a functional nucleus. To reach the region neurosurgeons utilize imaging and guiding methods to locate and demarcate the region of surgical interest (ROSI). This thesis has focused on the three most common intraoperative imaging modalities used in brain surgery, namely magnetic resonance imaging (MRI), ultrasound imaging (US) and computed tomography (CT). The aim was to form practical intraoperative imaging concepts for brain tumor resections and stereotactic procedures and then to evaluate their feasibility

Abstract Hip fracture is a significant problem in health care incurring major costs to society. Therefore, it is necessary to study fracture mechanisms and develop improved methods to estimate individual fracture risk. In addition to conventional bone density measurements, computational finite element (FE) analysis has been recognized as a valuable method for studying biomechanical characteristics of a hip fracture. In this study, computed tomography (CT) based finite element methods were investigated and simulation models were developed to estimate experimental femoral fracture load and hip f

Abstract Hip fracture is the most severe complication of osteoporosis. The occurrence of hip fracture is increasing worldwide as a result of the ageing of the population. The clinical assessment of osteoporosis and to some extent hip fracture risk is based on the measurement of bone mineral density (BMD) using dual X-ray absorptiometry (DXA). However, it has been demonstrated that most hip fractures occurring after a fall involve non-osteoporotic populations and that the geometry plays a critical role in the fracture risk assessment. A potential alternative for the assessment of hip fracture r
