Glossary of Molecular Imaging Terminology

Molecular imaging in living subjects: seeing fundamental biological processes in a new light

“…Further reviews of issues centered on molecular imaging techniques can be found elsewhere (Cherry and Gambhir 2001;Weissleder 2001Weissleder and Mahmood 2001;Chatziioannou 2002). Moreover, a glossary of molecular imaging terminology has been published recently to enhance collaborative efforts between multiple disciplines (Wagenaar et al 2001). Table 1 outlines some of the general characteristics of the imaging modalities available, and serves also as a simplified guide for biologists in choosing appropriate molecular imaging modalities and approaches.…”

In Vitro MR Imaging of Regulated Gene Expression

“…Tyrosinase is an MR imaging reporter enzyme that catalyzes two fundamental reactions during melanin synthesis. Melanin itself has a high iron-binding capacity that is responsible for intensified MR signals of cells that express the tyrosinase reporter gene (1,4).…”

An introduction to molecular imaging in radiation oncology: A report by the AAPM Working Group on Molecular Imaging in Radiation Oncology (WGMIR)

“…The number or density of molecular signals depends on the imaging technique and the targeted biological process or system. Definitions for the multidisciplinary terminology relevant for this field can be found in Cox and Nelson 18 and Wagenaar et al 19 and specifically for oncology in Pomper and Gelovani. 20 Five modalities are typically used for molecular imaging: (a) PET, (b) SPECT, (c) MRI, (d) optical, and (e) ultrasound.…”
