Labeled antibodies, antibody fragments or peptides binding to soluble cytokines or cytokine receptors are used to diagnose whether a patient has cancer or an autoimmune disease. In a preferred embodiment, a radiolabelled tag that is chemically bound to a peptide, antibody, or antibody fragment specific for sTNFR-1 and / or sTNFR2 is injected into a patient with a tumor, or suspected tumor, or with any disease associated with STNF-1 / STNF-2. The patient is then imaged using standard nuclear imaging equipment to detect areas or sites of concentration of the radiolabel and / or receptor / inhibitor and / or antigen. By screening for cancer by the substances it produces, using an injected antibody to that substance with a tracer attached to it, one can detect cancer at a very early stage, potentially even microscopically.

Systems, methods, and probes are provided for functional imaging by radioactive-emission-measurements, specific to body structures, such as the prostate, the esophagus, the cervix, the uterus, the ovaries, the heart, the breast, the brain, and the whole body, and other body structures. The nuclear imaging may be performed alone, or together with structural imaging, for example, by x-rays, ultrasound, or MRI. Preferably, the radioactive-emission-measuring probes include detectors, which are adapted for individual motions with respect to the probe housings, to generate views from different orientations and to change their view orientations. These motions are optimized with respect to functional information gained about the body structure, by identifying preferred sets of views for measurements, based on models of the body structures and information theoretic measures. A second iteration, for identifying preferred sets of views for measurements of a portion of a body structure, based on models of a location of a pathology that has been identified, makes it possible, in effect, to zoom in on a suspected pathology. The systems are preprogrammed to provide these motions automatically.
