 Advertisements will be sent to selected faculty within the departments of medicine and radiology with details of patient involvement and the selected physical findings which will be studied. Patients will be asked by their treating physician or radiologist involved in their care if they can be contacted by the study coordinator. The coordinator will then assess interest and availability. Patients will then be consented if they agree to participate. Fourteen patient-subjects will ultimately be selected to participate in our assessment program. They will be compensated 350 for participating.
