Abstract「要旨」 SPECTが普及してきてから多少膵シンチグラムの件数が増加している傾向にある. しかし本来, 75Se-selenomethionineの検査は慎重に行う必要があり, また超音波, CT, MR等の普及で, 膵シンチグラムの比重が減少していることは否めない. 26例について, 従来の膵シンチグラム, SPECT, X線CTを4人の医師による評価を数字化して検討した. 膵炎のごく一部に膵シンチグラムによる付加価値を認めるが, 腫瘍についてはX線CTに対して全く付加価値はなかった. また再現性も常にX線CTの方がよかった. SPECTは従来の膵シンチグラムに対して明瞭な利点は見いだせなかった.

Abstract[Summary] We studied the efficacy of pancreas scintigraphy using 75Se-selenomethionine by conventional method and SPECT in 26 patients diagnosed as pancreatic tumor or pancreatitis. X-CT was also performed in all patients and compared its efficacy with that of scintigraphy. In order to evaluate the image quality, 4 doctors analysed the images independently without clinical information and score them according to the possible abnormality. The average score of each film was adopted as an index for sensitivity, and the standard deviation was evaluated as objectiveness of the images. As for the detection of pancreatic tumor, both the sensitivity and the objectiveness of X-CT were superior to those of scintigraphies. However, evaluation by scintigraphy combined with X-CT increased the diagnostic sensitivity of pancreatitis than that of X-CT alone in some cases. These results suggest that the scintigraphy has no indication to suspected pancreatic tumor, but it still has some value in limited cases of pancreatitis. Almost no advantage was noted in SPECT combined with conventional image. Main reason was the artifact of SPECT preventing the accurate interpretation. Only benefits of SPECT were to decrease the false positive rate and to increase the objectiveness of 75Se-selenomethionine scan. When the scan is discussed as the examination, careful considerations should be done on the point of limited advantage on diagnostic efficacy and marked disadvantage of radiation to patients and environment.
