Outline of Final Research Achievements |
123I is more suitable for scintigram due to its energy spectrum. However,there is no report that compared two scans directly in iodine therapy. A total of 12 patients (average:58.8y.o. median:61y.o) with distant metastasis were incorporated in this study. We performed direct comparison of the result of two scans.Result of ten patients out of 12(83.3%) shows completely accorded with that of 131I. Lesion detection rate of 123 ,using 131I as a reference, was 100%(6/6) in lymph node metastasis、94.4%(17/18) in bone metastasis, 66.6%(2/3) in lung metastasis. Difference of uptake intensity was seen in 2 cases、and lung uptake measured by 123I was tend to be low compared with131I. 123I tends to have good separation of lesions, however there was no lesion only detectable by123I. less number of lesions were detectable by 123I and inferior to 131I, especially in the detection of131I. lung lesion
