I-ventriculography yenuzi

I-Nuclear ventriculography isivivinyo esisebenzisa izinto ezinemisebe ebizwa nge-tracers ukukhombisa amakamelo enhliziyo. Inqubo ayisebenzi. Izinsimbi azithinti inhliziyo ngqo.

Isivivinyo senziwa ngenkathi usaphumule.

Umhlinzeki wezokunakekelwa kwempilo uzojova into enemisebe ebizwa nge-technetium emthanjeni wakho. Le nto inamathela kumaseli abomvu egazi futhi idlule enhliziyweni.

Amangqamuzana egazi abomvu ngaphakathi enhliziyweni athwala okokusebenza akha isithombe esingathathwa yikhamera ekhethekile. Lezi scanner zilandelela into lapho ihamba endaweni yenhliziyo. Ikhamera inesikhathi nge-electrocardiogram. Ikhompyutha bese icubungula izithombe ukuze zenze kubonakale sengathi inhliziyo iyahamba.

Ungatshelwa ukuthi ungadli noma uphuze amahora ambalwa ngaphambi kokuhlolwa.

Ungase uzizwe ulunywa okwesikhashana noma uphine lapho i-IV ifakwa emthanjeni wakho. Ngokuvamile, kusetshenziswa umthambo engalweni. Ungaba nenkinga yokuhlala unganyakazi ngesikhathi sokuhlolwa.

Ukuhlolwa kuzokhombisa ukuthi igazi lifutha kanjani ezingxenyeni ezahlukahlukene zenhliziyo.

Imiphumela ejwayelekile ikhombisa ukuthi ukucindezela kwenhliziyo kuyinto ejwayelekile. Isivivinyo singahlola amandla wokukhama ngenhliziyo (ingxenyenamba yokukhipha). Inani elijwayelekile lingaphezu kuka-50% kuya ku-55%.

Ukuhlolwa nakho kungabheka ukunyakaza kwezingxenye ezahlukahlukene zenhliziyo. Uma ingxenye eyodwa yenhliziyo ihamba kabi ngenkathi ezinye zihamba kahle, kungasho ukuthi kube nomonakalo kuleyo ngxenye yenhliziyo.

Imiphumela engajwayelekile ingabangelwa:

• Ukuvaleka emithanjeni ye-coronary (isifo semithambo yenhliziyo)
• Isifo se-valve senhliziyo
• Ezinye izifo zenhliziyo ezenza buthaka inhliziyo (kunciphise umsebenzi wokumpompa)
• Ukuhlaselwa kwenhliziyo okudlule (i-myocardial infarction)

Isivivinyo singenzelwa futhi:

• Ukuqina kwenhliziyo
• Ukwehluleka kwenhliziyo
• Idiopathic cardiomyopathy
• I-Peripartum cardiomyopathy
• Ischemic cardiomyopathy
• Ukuhlola ukuthi umuthi uthinte ukusebenza kwenhliziyo

Ukuhlolwa kwe-imaging yenuzi kunengozi ephansi kakhulu. Ukuvezwa kwi-radioisotope kuletha inani elincane lemisebe. Leli nani liphephile kubantu abangenalo uvivinyo lwe-nuclear imaging kaningi.

Ukucabanga nge-cardiac pooling imaging; Ukuskena kwenhliziyo - okwenuzi; I-Radionuclide ventriculography (RNV); Ukuskena kokutholwa kwamasango amaningi (i-MUGA); Inhliziyo yenuzi; I-Cardiomyopathy - i-ventriculography yenuzi

• Inhliziyo - ukubuka kwangaphambili
• Ukuhlolwa kwe-MUGA
