^(99m)Tc-^(113m)In双核素技术在血管性勃起功能障碍诊断中的应用

Use of ^(99m)Tc-^(113m)In dual isotope in the diagnosis of vasculogenic erectile dysfunction

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

To evaluate the efficacy of dual isotopic technique in screening the pathogeny of vasculogenic erectile dysfunction (ED).A dual radioisotope study [ 99m technetium( 99m Tc) and 113m indium( 113m In)] were used in 56 men.The changes in 99m Tc and 113m In radioactivities were monitored before and after intracavernous papaverine plus prostaglandinum E 1 and audio visual sex stimulation test(AVSS).The results were judged by penogram index of arterial system (PIA,>60) and penogram index of venous system (PIV,>-48).The mean value of PIA and PIV in control group ( n =12) were 141.04 ±20.24 and -32.66±3.93.While in nonvasculogenic ED,both PIA and PIV are in normal range ( n =9);in venogenic ED ( n =23),PIA is in normal range and PIV out of the normal range;in arteriogenic ED ( n =5),PIV is in normal range and PIA is out of the normal range;in combined vasculogenic ED ( n =7),both the PIA and PIV are out of the normal range.The findings suggest that the dual radioisotope technique will be a useful,safe,objective and relative exact technique in the screening and evaluation of the vasculogenic erectile dysfunction patients.
