MICAD (Molecular Imaging and Contrast Agents Database)

Unrestricted Access


The Molecular imaging and contrast agent database (MICAD) is an online source of information on in vivo molecular imaging agents based on recommendations from the extramural community. The database includes agents developed for positron emission tomography (PET), single photon emission computed tomography (SPECT), magnetic resonance imaging (MRI), ultrasound (US), computed tomography (CT), and optical imaging. 


NCBI publishes a Help manual with sections for the NCBI Bookshelf and all of their databases and databanks.  It is located at http://www.ncbi.nlm.nih.gov/books/NBK3831/ .  

User tools and features

Users may search the contents by typing keywords into the available textbox or by browsing the table of contents.  A click on the plus (+) sign opens each section of the contents.  MICAD chapters are now accessible through PubMed. To retrieve a list of all MICAD records, query PubMed for "Molecular Imaging and Contrast Agent Database (MICAD)"[book].   There is a link on the home page of the “book” which allows users to download the latest list of FDA-approved contrast agents.  The MICAD staff has created the Molecular Imaging Probes and Contrast Agents List (MIP & CA List) by screening the PubMed/MedLine databases and other appropriate sources of such information. Only agents used in animal or human studies yielding in vivo data were selected for inclusion in the list. Although great care has been taken to accurately present all and only those imaging and contrast agents that fulfill the in vivo data criteria, this list is by no means considered complete. No one imaging modality has been given preference over the others and the omission of any agent(s) or the introduction of any errors in the list is purely unintentional. The MIP & CA List is subject to the same copyright and disclaimers as the rest of the MICAD content. Please read carefully the complete disclaimer information for MICAD before using the list.  A link to download the latest version of the list is also available on the MICAD home page.
