OBJECTIVES To assess the value of dual-energy contrast-enhanced computed tomography (CT) imaging for the detection of urinary stone disease using dual-source CT. MATERIALS AND METHODS Forty consecutive patients (mean age 46.6 +/- 16.2 years, range 27-85 years) suspected of having urinary stone disease underwent dual-source CT of the urinary tract. A 3-phasic CT scan protocol consisting of a s...

PURPOSE To provide additional functional information for tumor characterization, we investigated the use of dual-energy computed tomography for imaging murine lung tumors. Tumor blood volume and vascular permeability were quantified using gold and iodine nanoparticles. This approach was compared with a single contrast agent/single-energy CT method. Ex vivo validation studies were performed to d...

The Research about Advanced Multi Material Decomposition of Dual energy in Computed Tomography image to find the liver diseases. The Existing system Multi material Decomposition(MMD) to find the liver disease using single energy. It was use Virtual Unenhancement algorithm. which is digitally removal of the effect of contrast agents from contrast-enhanced dual-energy CT exams. In proposed Method...

Dual-energy computed tomography (DECT) is a medical imaging technique that uses two different energy levels of X-rays to provide more detailed information about the composition tissues and materials within body. DECT technology still relatively new but applications have been developed for urological field. For example, it can be used analyze stones determine whether they are likely made up calc...
