Routine body perfusion CT approaches clinical reality

November 28, 2006

The most crucial process to assess in a tumor for efficient management is neo-angiogenesis. Currently, no reliable biomarker is available to measure angiogenesis, and direct microvessel density assay requires frequent biopsies for serial tumor monitoring. Technological innovations in imaging, however, have enabled the capture of physiological information in addition to anatomic details. One promising imaging technique for acquiring physiological information about angiogenesis is perfusion CT, which provides anatomic information as well.
