1. Medical CT-scanners for non-destructive wood density and moisture content measurements
Abstract : Most methods to measure wood density and moisture content are destructive. One non-destructive technique is X-ray computed tomography (CT). The actual physical variable measured is the X-ray linear attenuation coefficient which is highly density dependent. READ MORE

2. Preoperative localisation of parathyroid adenoma in primary hyperparathyroidism using 99mTc-sestamibi SPECT/CT : an evolving scanning protocol
Abstract : Primary hyperparathyroidism (pHPT) is caused by one or more hyperfunctional parathyroid gland causing an inappropriately high release of parathyroid hormone (PTH) in relation to the calcium concentration in the blood. PTH acts on the bones to release more calcium and on the kidneys to reabsorb calcium, causing hypercalcemia. READ MORE

3. Computed Tomography and Magnetic Resonance Imaging in Determination of Human Body Composition. Methodological and Applied Studies
Abstract : Background: Computed tomography (CT) and magnetic resonance imaging (MRI) provide important research opportunities due to their unique capability of characterizing and quantifying tissues and organs. Ionizing radiation is a limitation using CT, and recent developments aiming to improve MRI for determination of body composition have not been validated. READ MORE

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

5. Clinical use of prognostic markers in head and neck cancer
Abstract : Head and neck cancer (HNC) is a heterogeneous group of tumors where squamous cell carcinoma is the most dominant. In 2020, 1640 new cases of HNC were reported in Sweden which accounted for 2.3% of the total cancer incidence. READ MORE
