PURPOSE To improve CT number reproducibility in helical CT, a newly developed controlled-orbit helical scan mechanism was applied. The authors developed a method for volumetric measurement of cerebral blood flow (CBF) with dynamic helical computed tomography (CT) after inhalation of xenon gas. MATERIALS AND METHODS In three subjects (two healthy men aged(More)
Cerebral vascular permeability is an important consideration in treatment for intracranial tumours. We have developed a new method to measure the cerebral vascular permeability quantitatively using a conventional X-ray CT scanner and iodinated contrast medium. We have already applied our method in 50 cases of intracranial tumour and 5 cases, which establish(More)
We report on the development of a novel analytical HPLC technique of nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, ketoprofen and naproxen, with an isocratic aqueous mobile phase. In this study, we designed a new pH- and temperature-responsive copolymer of N-isopropylacrylamide (NIPAAm), butyl methacrylate (BMA) and(More)
We developed a method to measure regional permeability of cerebral capillary vessels, extracellular fluid space volume, and vascular bed volume using multi-slice dynamic CT with iodinated contrast medium. We implemented the method as a novel software "BBB study", and evaluated it in four cases of brain tumor. The examination time was about 20 minutes, and(More)
