67Ga scanning was performed in 26 patients with hypernephroma (17 with only a primary lesion of hypernephroma, 4 with both primary and metastatic lesions, 2 with hypernephroma and pyelonephritis, and 3 with only a metastatic lesion after nephrectomy). In patients with primary lesions alone, the positive finding rate by67Ga scanning was low (26percnt;), and in metastatic lesions that by scanning was high (86percnt;). The practical conclusions are as follows:67Ga scanning is of little use as a diagnostic aid in primary lesion of hypernephroma, but may be useful in case with metastases with inflammatory disease.
