Abstract

The in vivo early detection of subcutaneous human tumors implanted in small animals was studied by laser-induced fluorescence reflectance imaging (FRI), with a hematoporphyrin (HP) compound as an exogenous optical contrast agent. Tumor detection was shown to be possible just 3 days after the inoculation of tumor cells, when tumors were neither visible nor palpable. However, this detection capability is limited to a temporal window of approximately 100 h from HP administration and to a low optical contrast of the tumor (<2).
