At present, the four factors leading to the highest

death rates of humanity are encephalemia, cancers, myocardial

infarct, and traffic accidents.

To each of the four factors,

makes it possible to observe, directly from the external side,

the functional status, size and location of the internal organs.

This possesses a unique value to the diagnosis of some

pathological development caused by occupation of organs.

example, the static display of nuclear medicine can diagnose

the pathological change concerning occupation in the case of i

liver cancer, with the rate of coincidence over 80-85% usually.

At present, the most advanced nuclear medical visual-display

technology, after undergoing the computer image reproduction,

has progressed from the static, qualitative and 2-dimensional

level to the kinetic, quantitative and 3-dimensional level.

For instance, the various isotopic laminal display (CT)

techniques have rendered it possible to observe the kinetic

growth or declining of the isotopic tracing agents in the

particular parts inside the human body, thus giving a

penetrating representation of the function and metabolism

of the organism.

This unique point enjoys tremendous clinical

value, because in the course of the emergence and development

of a disease, the functional change of the organism is usually

earlier than the formal and structural changes. In particular,
