An indium:calcium phosphate colloid that specifically targets fibrin.

The ability of indium to target fibrin in vitro was evaluated. The radionuclide (114m)Indium (114mIn) was prepared as a soluble and colloidal (In:In) form, as well as, a mixed indium:calcium phosphate (In:CaP) colloid. Soluble 114mIn was prepared by maintaining acid pH (50 mM HCl).

Natural display mode for digital DICOM-conformant diagnostic imaging.

Rationale And Objectives: The authors performed this study to investigate the verification of the contrast display properties defined by the digital imaging and communication in medicine (DICOM) PS (picture archiving and communication system [PACS] standard) 3.14-2001 gray-scale display function standard and their dependency on display luminance range and video signal bandwidth.

Materials And Methods: Contrast sensitivity and contrast linearity of DICOM-conformant displays were measured in just-noticeable differences (JNDs) on special perceptual contrast test patterns.
