Radboud Imaging Research
Welcome to the research website of the Department of Radiology and Nuclear Medicine at Radboud university medical center, Nijmegen.
Our research has a strong focus on early detection and early treatment of common diseases. It covers fundamental research on a molecular level, development of new medical devices and software tools, and translates these results to clinical applications that can be used in daily routine. Our mission is to bridge the gap between research and practice and to help shape the future of healthcare. We use technology to make healthcare more affordable by increasing automation of diagnostic and therapeutic procedures, thus freeing manpower for those areas in patient care in which the "human touch" is most needed.
The four fundamental science groups cover ultrasound (MUSIC), biomedical MR (BioMR), diagnostic image analysis (DIAG) and tracer research (TRACER). Clinical research is mainly focused on prostate, breast, chest and vascular disease.
Ewoud Smit et al. have published a paper in the American Journal of Neuroradiology entitled: Timing-Invariant CT Angiography Derived from CT Perfusion Imaging in Acute Stroke: A Diagnostic Performance Study.
Timing-invariant CT angiography (CTA) derived from CT perfusion (CTP) data may obviate a separate cranial CTA in acute stroke, thus enhancing patient safety by reducing total examination time, radiation dose, and volume of contrast material. Therefore, they assessed the diagnostic accuracy of timing-invariant CTA for detecting intracranial artery occlusion in acute ischemic stroke, to examine whether standard CTA can be omitted.
Overall, standard CTA and timing-invariant CTA provided similar high diagnostic accuracy for occlusion detection with a sensitivity of 96% and a specificity of 100% for standard CTA and a sensitivity of 98% and a specificity of 100% for timing-invariant CTA. For proximal large-vessel occlusions, the sensitivity and specificity were 100% for both techniques. They concluded that timing-invariant CTA derived from CTP data provides diagnostic accuracy similar to that of standard CTA for the detection of artery occlusions in acute stroke.
