Title: Comparison of I-123 IMP and Ga-67 citrate scintigraphy of malignant melanoma. Author: Murata K, Suzuki K, Ayakawa Y, Higashi N, Paul Lin PJ. Journal: Clin Nucl Med; 2003 Aug; 28(8):704-8. PubMed ID: 12897669. Abstract: I-123 iodoamphetamine (IMP) and Ga-67 scintigraphy of malignant melanoma were performed to compare the accumulation of these tracers regarding tumor diameter to determine the site of I-123 IMP accumulation and to evaluate the use of I-123 IMP and Ga-67 in postoperative follow-up. The studies involved 44 patients with a definite diagnosis of malignant melanoma during a 10-year period from April 1991 through March 2001. In this study a very high detection rate of 90.9% was obtained for primary foci with I-123 IMP. With Ga-67, the primary site detection rate was 25%. The results suggest that I-123 IMP is superior to Ga-67 with respect to the detection rate of primary site.[Abstract] [Full Text] [Related] [New Search]
