Kwenzelwa ini futhi kwenziwa nini umzimba wonke nge-scintigraphy?

• Lapho kwenziwa i-scintigraphy ephelele yomzimba
• Kwenziwa kanjani i-PCI
• Ukunakekelwa ngaphambi kokuhlolwa

I-scintigraphy yomzimba wonke noma ucwaningo lomzimba wonke (i-PCI) ukuhlolwa kwesithombe okucelwe ngudokotela wakho ukuphenya indawo yesimila, ukuqhubeka kwezifo, kanye ne-metastasis. Ngalokhu, kusetshenziswa izinto ezinemisebe, ebizwa nge-radiopharmaceuticals, njenge-iodine-131, i-octreotide noma i-gallium-67, kuye ngenhloso ye-scintigraphy, elawulwa futhi imuncwe izitho, ikhipha imisebe etholwa yimishini. Yazi ukuthi iodine enemisebe yenzelwe ini.

Izithombe zitholakala kusetshenziswa idivaysi, elandelela umzimba wonke, ngemuva kosuku noma ezimbili zokuphathwa kwento. Ngakho-ke, kungenzeka ukuqinisekisa ukuthi i-radiopharmaceutical isatshalaliswa kanjani emzimbeni. Umphumela wokuhlolwa kuthiwa ujwayelekile lapho into isatshalaliswa ngokulingana emzimbeni, futhi ikhombisa ukugula lapho ukubonwa okuphezulu kwe-radiopharmaceutical kutholakala engxenyeni noma esifundeni somzimba.

Lapho kwenziwa i-scintigraphy ephelele yomzimba

I-scintigraphy yomzimba wonke ihlose ukuphenya indawo eyinhloko yesimila, ukuvela nokuthi ngabe ikhona yini imetastasis. I-radiopharmaceutical esetshenzisiwe incike ekutheni iyiphi uhlelo noma isitho ofuna ukusihlola:

• I-PCI ene-iodine-131: inhloso yayo eyinhloko yi-thyroid, ikakhulukazi kulabo asebesuswe i-thyroid;
• IGallium-67 PCI: kuvame ukwenziwa ukubheka ukuvela kwama-lymphomas, ukusesha imastastasis nokuphenya izifo;
• I-PCI ene-octreotide: kwenziwa ukuhlola izinqubo zesimila semvelaphi ye-neuroendocrine, efana ne-thyroid, izimila zepancreatic kanye ne-pheochromocytoma. Bona ukuthi ungayibona kanjani futhi uyiphathe kanjani i-pheochromocytoma.

I-scintigraphy yomzimba wonke yenziwa ngaphansi kokuqondiswa kwezokwelapha futhi ayibonisi ubungozi esigulini, ngoba izinto ezinemisebe ye-radioactive zisuswa ngokwemvelo emzimbeni.

Kwenziwa kanjani i-PCI

Ukusesha okugcwele komzimba kwenziwa ngezinyathelo ezine:

1. Ukulungiswa kwezinto ezinemisebe yomthamo ezonikezwa;
2. Ukuphathwa komthamo esigulini, kungaba ngomlomo noma ngqo emthanjeni;
3. Ukuthola isithombe, ngokufunda okwenziwe yimishini;
4. Ukucubungula isithombe.

I-scintigraphy yomzimba wonke ayidingi ukuthi isiguli sizile, kepha kukhona ezinye izincomo okufanele zilandelwe ngokuya ngento okufanele inikezwe.

Endabeni ye-iodine-131, kunconywa ukuthi ugweme ukudla okunothe nge-iodine, njengezinhlanzi nobisi, ngaphezu kokumisa ukusetshenziswa kwemithi ethile, njengezithasiselo zamavithamini namahomoni wegilo ngaphambi kokwenza isivivinyo. Uma ukwenziwa kwe-scintigraphy okugcwele kungenziwanga, kepha kwenziwa kuphela i-scintigraphy yegilo, kufanele uzile ukudla okungenani amahora amabili. Bona ukuthi kwenziwa kanjani i-scintigraphy ye-thyroid nokuthi yikuphi ukudla okunothe nge-iodine okufanele kugwenyelwe ukuhlolwa.

Ukuhlolwa kwenziwa ngesiguli esilele ngesisu futhi kuthatha imizuzu engama-30 kuye kwengu-40. Ku-PCI ene-iodine-131 ne-gallium-67, izithombe zithathwa ngama-48h ngemuva kokuphathwa kwe-radiopharmaceutical, kepha uma kusolwa ukutheleleka, i-PCI ene-gallium-67 kufanele ithathwe phakathi kuka-4 no-6h ngemuva kokuphathwa kwento leyo. Ku-PCI ene-octreotide, izithombe zithathwa kabili, kanye namahora angaba ngu-6 futhi kanye namahora angama-24 okuphathwa kwezidakamizwa.

Ngemuva kokuhlolwa, umuntu angabuyela emisebenzini ejwayelekile futhi kufanele aphuze amanzi amaningi okusiza ukuqeda into enemisebe ngokushesha.

Ukunakekelwa ngaphambi kokuhlolwa

Ngaphambi kokuba kuhlolwe umzimba wonke, kubalulekile ukuthi umuntu atshele udokotela uma enanoma yiluphi uhlobo lokungezwani komzimba, uma esebenzisa noma imuphi umuthi oqukethe iBismuth, njenge-Peptulan, isibonelo, esetshenziselwa i-gastritis, noma uma ukhulelwe noma uncelisa, njengoba lolu hlobo lokuhlola lunganconyiwe, ngoba lungathinta ingane.

Imiphumela emibi ehlobene nokuphathwa kwe-radiopharmaceuticals ayivamile, hhayi ngoba kusetshenziswa imithamo ephansi kakhulu, kepha ukusabela okweqile, ukuqubuka kwesikhumba noma ukuvuvukala kungenzeka esifundeni lapho kufakwa khona into. Ngakho kubalulekile ukuthi udokotela asazi isimo sesiguli.
