  2. 1. CT Urography : Efforts to Reduce the Radiation Dose

    Author : Pär Dahlman; Anders Magnusson; Anders Sundin; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Urinary tract malignancy; renal cell carcinoma; urography; x-ray computed tomography; radiation dosage; dose escalation; hematuria diagnosis; Diagnostic radiology; Diagnostisk radiologi; Radiologi; Radiology;

    Abstract : Computed tomography urography (CTU) is today the imaging method used to investigate patients with suspected urinary tract malignancy, replacing the old imaging method intravenous pyelography (IVP) about a decade ago. The downside of this shift was that the effective radiation dose to the examined patient was eight times higher for CTU compared to IVP. READ MORE

  4. 2. Diagnosis and evaluation of therapeutic response of bone metastases

    Author : Ipek Çiray; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Bone metastases; breast neoplasm; MR imaging; CT; diagnosis; therapy evaluation; Onkologi; Oncology; Onkologi; diagnostisk radiologi; Diagnostic Radiology;

    Abstract : The aim of this study was to investigate different aspects of different imaging modalities in the diagnosis of bone metastases and in the assessment of their response to therapy. The role of CT, with and without clinical information, was investigated as compared to CT-guided bone biopsy in the evaluation of suspected bone metastases. READ MORE

  5. 3. Scaphoid Fractures - epidemiology, diagnosis and treatment

    Author : Peter Jörgsholm; Malmö Handkirurgi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Scaphoid fracture; carpal fracture; paediatric; radiography; CT; MRI; arthroscopy; scapholunate ligament injury; radial comminution; surgical treatment; conservative treatment; fracture union;

    Abstract : Abstract The scaphoid is the most commonly fractured carpal bone. The diagnosis is difficult and untreated the long-term results are poor. Approximately 10% do not unite even if they are treated properly. The aim of this thesis was to study scaphoid fracture epidemiology, diagnosis and treatment. READ MORE

  6. 4. CT Colonography: implementation and technical developments

    Author : Valeria A Fisichella; Göteborgs universitet; []
    Keywords : X-ray Computed Tomography; Computed Tomographic Colonography; Computer-Assisted Image Processing; Three-Dimensional Imaging; Colonoscopy; Colon; Rectum; Colorectal Neoplasms; Computer-Assisted Diagnosis; Ionizing Radiation;

    Abstract : Background: Computed tomographic colonography (CTC) is a minimally invasive imaging method for the detection of colorectal neoplasms. Uncertainty about its diagnostic performance, optimal visualization method, long learning curve and radiation exposure are among problems with CTC, affecting its implementation in routine health care.

  7. 5. Aortic valve imaging - Towards new standards in prosthetic valve endocarditis

    Author : Erika Fagman; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; prosthetic valve endocarditis; aortic valve endocarditis; ECG-gated CT; cardiac CT; 18F-FDG PET CT;

    Abstract : Background: Aortic prosthetic valve endocarditis (PVE) is a disease with high mortality, and diagnosis is difficult. Transesophageal echocardiography (TEE) has been the mainstay imaging modality in the diagnostic workup, but TEE has diagnostic shortcomings. Thus, new imaging methods might improve the diagnostic workup of PVE. READ MORE
