A study on reference based time intensity curves quantification in DCE-MRI monitoring of rectal cant (typically Gadolinium DTPA) and, subsequently, the assessment of signal intensities changes over time. The signal intensity on T1-weighted images can be considered proportional to the concentration of contrast agent..The intensity-time curve can be studied trough semiquantitative parameters. Time

Metal Artifact Reduction in CBCT Using Forward Projected Reconstruction Information and Mutual Infography images. We present a novel method for metal artifact reduction in cone-beam computed tomography images via virtual replacement of the metal objects in the 3D volume with objects of identical geometry but water like x-ray attenuation coefficient. As the 3D scan procedure for CBCT of mobile C-a

Comparison of Advanced Iterative Reconstruction Methods for SPECT/CT, 40sec./frame) of a resolution and the NEMA NU2-2001 image quality phantom was performed. Reconstructions were done using Evolution for bone (GE), Flash3D (Siemens) and Astonish (Philips). The reconstructed slices were either analyzed directly or after additional post-filtering according to the manu

Imaging Properties of Digital Magnification Mammography,onditions of a matched average glandular dose (AGD). The AGD in each magnification mammography was matched to that of conventional contact mammography with 4 cm breast thickness. A dedicated mammographic unit with nominal focal spot sizes of 0.1 mm and 0.3 mm, molybdenum anode and 0.03 mm molybdenum
