Abstract
Ukungasebenzi kakuhle kwengqondo kwi-erectile dysfunction (ED) ichongiwe kwizifundo ezininzi ze-neuroimaging. Uphononongo lwamva nje lweMRI lubonise utshintsho kwimicimbi engwevu kwizigulana ze-ED. Olu phononongo lujolise ekuphandeni utshintsho olwenziwe ngobuchwephesha kwimiba emhlophe yecerebral (WM) kwizigulana ze-ED zengqondo kunye nokunxibelelana okunokubakho nezinto eziguquguqukayo zeklinikhi. Izigulana ezingamashumi amabini anesixhenxe ze-ED zeengqondo kunye nezifundo ze-27 ezinempilo (i-HS) zibandakanyiwe kwaye zenziwa ukuskena nge-magnetic resonance (MR) yokusasaza i-imaging tensor imaging (DTI). Iinkcukacha-manani ezisekwe kwiteknoloji zaqeshwa ukuchonga ulwakhiwo lweWM kwizigulana zengqondo ze-ED. Ii-indices ezininzi ezivela kwi-DTI '[i-anisotropy ye-fractional anisotropy (FA), i-axial diffusivity (AD) kunye ne-diffusivity (MD)] unxibelelwano kunye neempawu kunye nexesha labo, ngokwahlukeneyo, zahlalutywa. I-IIEF-5, umgangatho wemibuzo yokwakhiwa (QEQ) kunye nokuzithemba kunye nolwalamano (SEAR) iphepha lemibuzo lalisetyenziselwa ukuvavanya iimpawu zezigulana zengqondo ze-ED.
Xa kuthelekiswa ne-HS, izigulana ze-ED zengqondo zibonise ukonyuka kwamaxabiso e-FA, ukunciphisa amaxabiso e-MD kunye nokunciphisa amaxabiso e-AD kumaphecana amaninzi e-WM kubandakanya i-corpus callosum (i-genu, umzimba kunye ne-splenium), i-corticospinal tract, i-capsule yangaphakathi, i-corona radiata, i-capsule yangaphandle kunye ne-longitudinal ephezulu I-fasciculus (p <0.05, ukulungiswa kweqela elingenasiphelo kulungisiwe).
Zombini amanqaku e-IIEF kunye ne-QEQ yamanqaku ezigulana ze-ED abonise ukungqinelani okungahambelani kakuhle namaxabiso aphakathi e-FA, kunye nokunxibelelana okuqinisekileyo kunye nexabiso eliphakathi le-AD kunye ne-MD amaxabiso kwi-splenium ye-corpus callosum (p <0.05).
Iziphumo zabonelela ubungqina bokuqala beenguqu zemozulu ye-WM kwizigulana ezinokusebenza kwengqondo ye-ED. Utshintsho lwe-morphological kwi-splenium ye-corpus callosum yayihambelana nobunzima beempawu.
