过去我曾说过:“核医学已经到了一个转折点而不去转折是错误的”。这次第32届美国核医学年会清楚表明,核医学正在开始转折,而且面临着变革的挑战。加速器和正电子正在成为核医学的新焦点。 50年代,~(131)Ⅰ标记物占统治地位,60年代是~(99m)Tc,70年代是~(201)Tl,80年代是~(11)C,~(18)F和~(123)Ⅰ。我相信,90年代有5种放射性核素将占优势,它们是~(11)C、~(18)F、~(15)O、~(123)Ⅰ和~(99m)Tc。
In the past I said: “Nuclear medicine has reached a turning point without turning around is wrong.” The 32nd annual meeting of the U.S. Nuclear Medicine Institute made it clear that nuclear medicine is beginning to undergo a turnaround and faces the challenge of change. Accelerators and positrons are emerging as the new focus of nuclear medicine. In the 1950s, ~ (131) I markers dominated, ~ 99m Tc in the 1960s, ~ 201 Tl in the 1970s, ~ 11 C, 18 F and 123 in the 1980s ) Ⅰ. I believe there will be five types of radionuclides that will dominate in the 1990s. They are ~ (11) C, ~ (18) F, ~ (15) O, ~ (123) I and ~ (99m) Tc.
