Limitations of Brain Imaging Techniques

Although imaging techniques such as PET and SPECT have helped bring about tremendous advances in the study of brain diseases, they have some limitations:

·        The use of radioactive substances in PET and SPECT limits the number of times a person can undergo these tests. There is the risk that the client will have an aller-gic reaction to the substances. Some clients may find receiving intravenous doses of radioactive material frightening or unacceptable.

·        Imaging equipment is expensive to purchase and maintain, so availability can be limited. A PET camera costs about $2.5 million; a SPECT camera costs about $500,000.

·        Some persons cannot tolerate these procedures because of fear or claustrophobia.

·        Researchers are finding that many of the changes in dis-orders such as schizophrenia are at the molecular and chemical levels and cannot be detected with current imaging techniques (Fujita et al., 2005; Vythilingam et al., 2005).
