Methods 24 primary and pre-treated patients diagnosed with multiple myeloma according to the International Myeloma Working Group criteria were examined by F-FDG PET/CT and whole-body MRI including DWI (b= 0, and b= 800 s/mm). F-FDG PET/MRI was used to achieve correct matching of findings in the corresponding PET/ CT study. Suspicious lesions were defined by the imaging gold-standard of nonenhan...
Osteoma is a benign bone-forming tumor that usually arises in the craniofacial bones and rarely in the long bones. Clavicular involvement is extremely rare. We report a 51-year-old woman with osteoma of the left clavicle. Radiograph of the left shoulder showed a well-defined lobulated blastic mass in the proximal and mid-portion of the left clavicle. Bone scintigraphy was performed 4 hours afte...

PII: S0167-7799(02)02027-9 Ladurner and colleagues [1] were the first to use computed tomography (CT) to study physiological function in the human brain by measuring cerebral blood volume with intravenously injected X-ray contrast agent (an iodinated compound that preferentially stops X-rays more effectively than...
Alzheimer's disease (AD) alters the functional connectivity of the default mode network (DMN) but also the topological properties of the functional connectome. Cognitive training (CT) is a tool to slow down AD progression and is likely to impact on functional connectivity. In this pilot study, we aimed at investigating brain functional changes after a period of CT and active control (AC) in a g...
The saga of CT coronary angiography continues and new exciting developments are on the horizon. We have witnessed the astounding rapid developments in CT technology from 4-, 16-, 64-, 128-, 256-, to 320-slice acquisition, with tube rotational speed increasing from 250 to 87 ms and with ever decreasing radiation exposure from 20 to ,1 mSv with the preservation of image quality. One would think t...
