The National Nuclear Data Center (NNDC) provides nuclear data through 40 websites, many of which are being updated to make easier find. most visible change is a site-wide navigation menu that links the NNDC’s most-visited databases. Evaluated Structure File (ENSDF) front page now also has chart interface for visual exploration its data. NuDat 3.0 faster, smoother, and feature-rich interactive C...

BACKGROUND PET/CT has recently been shown to be a viable alternative to traditional post-infusion imaging methods providing good quality images of 90Y-laden microspheres after selective internal radiation therapy (SIRT). In the present paper, first we assessed the quantitative accuracy of 90Y-PET using an anthropomorphic phantom provided with lungs, liver, spine, and a cylindrical homemade lesi...

In internal radionuclide therapy, a growing interest in voxel-level estimates of tissue-absorbed dose has been driven by the desire to report radiobiologic quantities that account for the biologic consequences of both spatial and temporal nonuniformities in these dose estimates. This report presents an overview of 3-dimensional SPECT methods and requirements for internal dosimetry at both regio...

UNLABELLED The constant-volume urinary bladder model in the standard MIRD Pamphlet No. 5 (Revised) phantom has recognized limitations. Various investigators have developed detailed models incorporating more physiologically realistic features, such as expanding bladder contents and residual volume, and variable urinary input rate, initial volume and first void time. We have reviewed these publis...
