[Statistical analysis of nuclear medicine in the Higashi Nippon Gakuen University Dental Hospital]

The number of radionuclide in vivo tests carried out at the Higashi Nippon Gakuen University Dental Hospital was statistically analyzed and discussed. The subjects were all patients admitted to the Division of Nuclear Medicine during the seven years between 1981 and 1989. The total number of the patients included those introduced through medical facilities in Toubetsu-cho and others. The results of this analysis were as follows: 1) The proportion of the first time patients admitted to the Higashi Nippon Gakuen University Dental Hospital was only 11 percent of all patients. 2) Cases of radionuclide in vivo tests at the Higashi Nippon Gakuen University Dental Hospital decreased in number, annually. However the proportion of tumor scintigraphy and bone scintigraphy increased gradually.
