  • Patent number: 8475763
    Abstract: A method for detecting antigen associated with adenocarcinoma commences by forming a 124I conjugate of a preferential locator, such as an antibody, and introducing the conjugate into a patient suspected of having adenocarcinoma. Positron emission tomography (PET) scanning of the patient reveals sites of accumulated conjugate, such sites including lymph nodes. The course of treatment of the patient then is determined by the amount of revealed lymph nodes.

  • Patent number: 7738946
    Abstract: System, method and apparatus wherein a probe employing non-imagining optics is utilized in conjunction with a fluorescing (e.g., nanocrystal) tracer at the body of a patient. Excitation components within the probe working end are utilized to excite the nanocrystals to fluoresce at wavelengths in the near infrared region, such fluorescent energy is homogenized by interacting with involved tissue to provide a uniform fluorescing intensity over the surface of a photo-detector. Initialization and background determination procedures are described along with a technique for determining statistically significant levels of fluorescing activity.
