Molecular imaging: an old and new field connecting basic science and clinical medicine.

Combination of recent progress in imaging technology and molecular biology/gene technology has evolved a new field named "molecular imaging". It includes wide range of imaging technique from basic research to clinical practice. For basic researchers, we focused on the part of in vivo imaging in human, and introduce the recent progress of modern biomedical imaging, as a crossing point of basic science and clinical medicine.
