  2. 11. CT with 3D-Image Reconstructions in Preoperative Planning

    Author : Angeliki Dimopoulou; Anders Magnusson; Anders Persson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CT Angiography; 3D-image reconstructions; haemodialysis; AVF AVG; DIEP flap; surgery time; complicated renal calculi; PNL; true nonenhanced images; virtual nonenhanced images; CT Urography; Radiology; Radiologi;

    Abstract : Computed tomography is one of the most evolving fields of modern radiology. The current CT applications permit among other things angiography, 3D image reconstructions, material decomposition and tissue characterization. CT is an important tool in the assessment of specific patient populations prior to an invasive or surgical procedure. READ MORE

  4. 12. Quantifying the quality of medical x-ray images. An evaluation based on normal anatomy for lumbar spine and chest radiography

    Author : Anders Tingberg; Malmö Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical physics; normal anatomy; free response forced error FFE ; receiver operating characteristics ROC ; visual grading analysis VGA ; European image criteria; quantifying clinical image quality; radiology; tomography; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

    Abstract : Optimisation in diagnostic radiology requires accurate methods for determination of patient absorbed dose and clinical image quality. Simple methods for evaluation of clinical image quality are at present scarce and this project aims at developing such methods. READ MORE

  5. 13. Patients and Staff in the Hybrid Operating Room: Experiences and Challenges

    Author : May Bazzi; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hybrid operating room; patient experience; nursing staff; endovascular aortic repair; teamwork; video recordings; interviews; radiology; surgery; anesthesia;

    Abstract : The hybrid operating room (OR), which combines a traditional OR with a radiological intervention room, is one example of the technical advancements within hospitals. In a hybrid OR, the staff have to manage the technique confidently in a not completely familiar environment and still be able to care for the vulnerable patient in the safest way. READ MORE

  6. 14. Radiological methods in rheumatoid arthritis and osteoarthritis

    Author : Tomas Söderman; Adel Shalabi; Anders Sundin; Suzanne Werner; Marie-Louise Wretling; Seppo Koskinen; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rheumatoid arthritis; Cervical spine; Radiography; Computed tomography; Magnetic resonance imaging; ACL reconstruction; Knee laxity; Long-term evaluation; Osteoarthritis; KOOS; SF-36; Tegners Activity Scale; IKDC; Quality of life; Radiology; Radiologi;

    Abstract : The dissertation's theme is the critical role of radiology when evaluating two different groups of patients. Firstly, patients with rheumatoid arthritis (RA) of the cervical spine were studied to evaluate upper spine instability with dynamic computed tomography (CT). READ MORE

  7. 15. Core Biopsy of Breast and Axillary Lesions : Technical and Clinical Aspects

    Author : Shahin Abdsaleh; PG Lindgren; Per Skaane; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiology; Automatic core needle biopsy; Semiautomatic core needle biopsy; Surgical specimen; Dynamic needle behavior; Hormone Receptors; Radiologisk forskning; Radiological research; Radiologisk forskning;

    Abstract : The aims of this work were to image and analyze the needle behavior at automated core biopsy, to investigate the clinical utility of an alternative core biopsy technique using a semiautomated gun in breast and axillary lesions, and also to compare core biopsy with surgical specimens in malignant breast lesions regarding histologic features and hormone receptor expression.In two experimental studies, using butter and silicon phantoms, respectively, the needle pass was imaged and its dynamic behavior studied.
