  2. 11. Experimental treatment of patients with disseminated malignant melanoma

    Author : Aglaia Schiza; Gustav Ullenhag; Angelica Loskog; Sara Mangsbo; Thomas Tötterman; Ola Winqvist; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Malignant melanoma; AdCD40L; immunotherapy; proteomics; DW-MRI; FDG-PET CT; prediction; early response; BRAF-inhibitor; vemurafenib; Oncology; Onkologi;

    Abstract : Malignant melanoma (MM) is the deadliest skin cancer with an ever-increasing incidence. New treatments have improved the prognosis for patients with advanced MM. Still, most patients do not respond, and the side effects can be severe, underlining the need for better therapies. READ MORE

  4. 12. Methods of image acquisition and calibration for x-ray computed tomography

    Author : Martin Sjölin; Mats Danielsson; J. Webster Stayman; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Medical Technology; Medicinsk teknologi;

    Abstract : X-ray computed tomography (CT) is a common medical imaging device for acquiring high-resolution 3D images of the interior of the human body. The images are formed by mathematical reconstruction from hundreds of planar x-ray images that have been acquired during less then a second. READ MORE

  5. 13. Exploring new protocols in emergency radiology, and their impact on radiation and diagnosis

    Author : Ali Latifi; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Computed tomography (CT) has become the predominant radiological examination in thoracic and abdominal emergencies. The increasing use of CT, both for diagnosis and follow-up and the continued development of the CT technique demand that we improve our examination protocols constantly. READ MORE

  6. 14. Optimizing computed tomography : quality assurance, radiation dose and contrast media

    Author : Patrik Nowik; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Computed tomography (CT) is an important modality in radiology; it enables imaging of the inside of patients without superimposed anatomy. The radiation dose and quality of a CT image are highly dependent on the CT scanner, the scan settings and, if applicable, the timing and dosage of the intravenous contrast media (CM). READ MORE

  7. 15. Visual grading evaluation of reconstruction methods and dose optimisation in abdominal Computed Tomography

    Author : Bharti Kataria; Michael Sandborg; Örjan Smedby; Anders Persson; Hannibal Sökjer; Håkan Geijer; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Since its introduction in the 1970’s CT has emerged as a modality of choice because of its high sensitivity in producing accurate diagnostic images. A third of all Computed Tomography (CT) examinations are abdominal CTs which deliver one of the highest doses among common examinations. READ MORE
