By Henry N. Wagner

Taking either a historic and philosophical stance, mind Imaging: The Chemistry of psychological job offers an in depth account of molecular imaging at its most interesting. Written through Dr. Henry N. Wagner Jr, a hugely acclaimed writer and overseas authority within the box of nuclear drugs, the publication brings thus far all of the interesting paintings found in mind imaging, exhibiting the variations one of the a number of imaging modalities, and reviewing the data of chemical reactions within the mind.

This brought about a new view of disease. The germ theory of disease views disease as a struggle between a human host and offending bacterial organisms, many of which are normal flora that become infectious. Anton van Leeuwenhoek’s invention of the microscope in the seventeenth century made it possible for the first time to see the bacteria themselves. PET and SPECT let us image the molecules within the body. In 1876, Robert Koch proposed four postulates that needed to be met to establish that a specific microorganism was the cause of a disease: (1) the organism had to be present in all patients with the disease; (2) the organism had to be isolated from the patient; (3) when the organism is injected into a susceptible host, it must cause the same disease as that in the original host; and (4) the organism must be isolated a second time from the infected host.

(b) Dr. David Kuhl and Dr. R. Q. Edwards. (c) Schematic drawing of the first tomographic scanner. A Molecular Theory of Mental Disease 41 Fig. 2 (continued) Kuhl’s group carried out the first imaging of glucose utilization in the human brain with FDG, an analog of glucose. They found regional abnormalities in the use of brain glucose before there were demonstrable structural changes in patients with stroke, senile dementia of the Alzheimer type, and Huntington’s disease.

PET and SPECT let us read the book. Our administrative leaders at Johns Hopkins were skeptical. On February 8, 1979, I received a letter from Dr. Bob Heyssell, Director of Johns Hopkins Hospital (before coming to Johns Hopkins, he had been head of nuclear medicine at Vanderbilt University). ” He had read an article written by Jon Franklin, a Pulitzer Prize-winning reporter from The Baltimore Sun, which said: “Johns Hopkins scientists say they will install a scanner A Molecular Theory of Mental Disease 39 capable of watching the chemical process of thought as it flickers through the brain … It is designed to help map the circuitry of thought and allow scientists to understand how information is processed by the brain … Once brain specialists understand how energy flows through the brain, they should be able to pinpoint the problem in patients with certain diseases, including schizophrenia, senility, Huntington’s disease, Parkinson’s disease, manic-depressive psychosis, drug addiction and manganese poisoning …” “Dr.
