Patent ID: 7700075

Claim:
A method of diagnosing cancer in a selected region of the intestinal tract using dual modality virtual colonoscopy in vivo, comprising the steps of: administering the radiolabeled 18-(4-iodophenyl)-octadecylphosphocholine; using computed tomography or magnetic resonance imaging to produce a visualization of the three-dimensional morphology of the selected region suspected of having a malignant tissue; using positron emission tomography or single photon emission tomography to produce a visualization of the distribution of the radioactivity produced by the radiolabeled 18-(4-iodophenyl)-octadecylphosphocholine; and comparing the visualization of the morphology of the selected region to the visualization of the distribution of the radioactivity produced by the radiolabeled 18-(4-iodophenyl)-octadecylphosphocholine, wherein the presence of radioactivity indicates the malignant tissue.
