ABSTRACT:
A detectably labeled porphyrin compound for identifying a sentinel lymph node in patients, particularly those with cancer. A method of identifying a sentinel lymph node, comprising the steps of: injecting the detectably labeled porphyrin compound into a tumor, wherein the porphyrin compound is detectably labeled with a radiolabel which is a γ-emitting radioactive metal; and detecting radioactive emission or a color so as to detect and thereby identify the sentinel lymph node. A method of identifying a sentinel lymph node, comprising the steps of injecting the detectably labeled porphyrin compound into tissue surrounding a tumor, wherein the porphyrin compound is detectably labeled with a non-radioactive metal; and taking a series of magnetic resonance images to identify the sentinel lymph node by viewing the images showing the injected detectably labeled porphyrin compound.
