  5. 3. Dual-energy imaging in stroke : feasibility of dual-layer detector cone-beam computed tomography

    Author : Fredrik Ståhl; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Background: Dual-energy computed tomography (DECT) is increasingly available and used in the standard diagnostic setting of ischemic stroke patients. For stroke patients with suspected large vessel occlusion, cone-beam computed tomography (CBCT) in the interventional suite could be an alternative to CT to shorten door to thrombectomy time.

    Abstract : X-ray computed tomography (CT) is a widely used imaging modality that enables visualization of nearly every part of the human body. It is used for diagnosis of disease and injury as well as medical treatment planning. READ MORE

  7. 5. Pharmacological Modulation of Skeletal Homeostasis

    Author : Niklas U. Andersson; Institutionen för experimentell medicinsk vetenskap; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Farmakologi; toxicology; farmakognosi; farmaci; toxikologi; pharmacy; pharmacognosy; Pharmacological sciences; peripheral quantitative computed tomography.; dual energy X-ray absorptiomenty; estrogen; parathyroid hormone; gastrectomy; alendronate; ovariectomy; Bone;

    Abstract : Both ovariectomy (OVX) and gastrectomy (GX) cause osteopenia in several animal species including humans. While the effect of OVX has been ascribed to estrogen deficiency, the underlying mechanism behind GX-induced osteopenia is poorly understood. READ MORE
