In 98 cases, Ga-67 citrate scintigraphic examination was performed from November 1983 to March 1985 in Kagawa Medical School Hospital. A restrospective evaluation of these cases showed that 38 cases (38.8%) did not meet indication for a Ga-67 study according to HISADA'S criteria. Of these 38 cases a positive Ga-67 uptake was shown in only 5 cases. Although application of Ga-67 detection is limited, many patients appear to receive a Ga-67 study without indication. The expensive Ga-67 study should be performed only in indicative cases.
