为评价双核素技术对筛选血管性勃起功能障碍 (ED)病因的效用 ,分别用99mTc、113mIn标记 5 6位男子的阴茎动、静脉血 ,观察其阴茎海绵体血流动力学变化。结果 12例正常男子PIA为 141.0 4± 2 0 .2 4(正常值 >6 0 ) ,PIV为 - 32 .6 6± 3 .93(正常值 >- 48)。而非血管性ED 9例 ,PIA为 98.85± 9.2 1(正常 ) ,PIV为 - 36 .42± 3 .0 6(正常 ) ;静脉性ED 2 3例 ,PIA为 136 .36± 17.0 7(正常 ) ,PIV为 - 74.11± 2 .73(异常 ) ,动脉性ED 5例 ,PIA和PIV分别为 :2 6 .10± 6 .85 (异常 )、- 2 7.76± 3 .89(正常 ) ;混合血管性ED :7例 ,PIA为 32 .70± 5 .13 ,PIV为 - 6 4.36±5 .40 (均异常 ) ,作者认为联合应用ICI和99mTc 113mIn双核素技术可以初步区分血管性ED中的具体血管问题
In order to evaluate the effect of binuclear technology on the etiology of screening for erectile dysfunction (ED), the penile arterial and venous blood of 56 men were labeled with 99mTc and 113mIn, and the hemodynamic changes of the penis were observed. Results The PIA of 12 normal men was 141.0 4 ± 2.04 (normal> 60) and PIV was - 32.66 ± 3.93 (normal> - 48). 9 cases of non-vascular ED, PIA was 98.85 ± 9.21 (normal), PIV was -36.42 ± 3.06 (normal), venous ED 2 was 3 cases, PIA was 136.36 ± 17.0 7 (normal ), PIV was -74.11 ± 2.73 (abnormal), Arterial ED was found in 5 cases, PIA and PIV were: 2.10 ± 6 .85 (abnormal), -2.76 ± 3.89 (normal), mixed Vascular ED: 7 cases, PIA 32 .70 ± 5 .13, PIV was -6.436 ± 5.40 (all abnormal), the authors believe that the combination of ICI and 99mTc 113mIn dual-nuclide technology can be initially differentiated in vascular ED Specific vascular problems
