Cancer-focused molecular imaging.

Molecular imaging, based largely on recent advances in genetics, genomics and high-throughput computational analysis, uses isotope-labeled probes to target specific cell surface molecules, tumor proteins and enzymes. This cross-disciplinary imaging modality undoubtedly will make profound changes in medical, surgical and radiologic practice. Physiology-based imaging modalities naturally are relevant for molecular studies. As a relatively new discipline, molecular imaging is accompanied by much hope for improved cancer diagnosis and treatment.
