I-Spiral CT engiography (ikhompyutri ye-tomography angiography) yindlela yokuphanda eyenza ukuboniswa kwemithambo yegazi (imithwaba, imirhoxo) kunye novavanyo olulandelayo lwemiqathango yabo kunye nohlobo lokuhamba kwegazi kuzo. Le ndlela iqhutyelwa kusetyenziswa i-device ekhethekileyo-i-tomograph, apho umfanekiso wesithathu weempahla uyadalwa yi-X ray kunye nokusetyenziswa kwekhompyutha. I-CT engiographie ayiyiyo intshabalala, kunye nokukhanya kweminye imitha.
Imiqondiso ye-CT engiography
Inkoliso ye-CT-angiography isetyenziselwa ukufunda i-coronary arteries, i-pulmonary veins kunye neetriyri, i-araca yesisu kunye nesisu, i-artery carotid, imithwalo yeentso, imithwalo ye-artery. Ukuxilongwa kugqityiweyo ukuchonga ukungaqhelekanga kokuphuhliswa kwamathambo, i-thrombosis, i-stenosis kunye nokuphazamiseka, ezinye iisetyhula kunye ne-pathologies ye-cardia. Izimpawu eziphazamisayo ezisebenza njengesiseko salolu cwaningo zi:
- rhoqo utywala , intloko;
- ukugada kwamalungu;
- ukuphazamiseka kwamehlo, ukuva;
- ukukhubazeka kwememori ;
- ukuphuma, njl njl
Amalungiselelo okuhlukelelwa kwe-CT engiography
Ukwandisa ukuhluka komfanekiso kwaye ufumane umfanekiso ochanekileyo wendlela yokujikeleza nge-CT engiographie, i-agent ekhethekileyo ye-radiopaque ene-iodine iyafakwa emzimbeni. Ngenxa yoko, i-canula kunye ne-catheter zifakwe kwi-vein veinar, apho iziza ezichaseneyo ziya kuhanjiswa kwi-distributer ngezinga elithile. Kwixesha elizayo, liya kukhishwa emzimbeni ngokusebenzisa izintso ngendlela engokwemvelo.
Iingxaki kunye nemiphumo yezobugcisa zixhomekeke kakhulu ekusebenziseni i-ejenti eyahlukileyo, enokubangela ukuphendulwa komzimba. Ukongeza, isilwanyana esisetyenzisiweyo singathintela imeko yezintso. Ngoko ke, ngaphambi kokuvavanywa, isigulane kufuneka senze iimvavanyo ezithile.
