Momma yensua Radiopharmaceuticals ho ade wɔ ɔkwan a ɛnyɛ den so. Eyi bɛyɛ nea ɛho hia wo paa!

Ebia ehu ka wo kakra bere a wote asɛmfua "radiopharmaceuticals" no, ɛnte saa? Asɛmfua "radioactive" ma yɛkae biribi a ɛyɛ hu ntɛm ara, nanso sɛ wɔde di dwuma yiye wɔ nnuruyɛ mu a, ebetumi aboa kɛse. Enti ɛnnɛ, momma yɛnka nea wɔyɛ, sɛnea wɔyɛ adwuma, ne sɛnea ahobammɔ wom ma wo ho asɛm.

Dɛn ne nnuru a wɔde yɛ radiopharmaceuticals yi? Momma yɛnte ase kɛkɛ!

Sɛ yɛbɛka no tiawa a, saa `(Radiopharmaceuticals)` yi nso yɛ nnuru soronko bi . Nanso wɔwɔ radioactive element kakra, kyerɛ sɛ, wɔyɛ radioactive. Mma ɛnhaw wo, eyi yɛ radioactivity a wɔahyɛ so, a ahobammɔ wom. Yɛn nnuruyɛfo, kyerɛ sɛ, nnuruyɛfo ne akwahosan ho adwumayɛfo a wɔde wɔn ho hyɛ mu no de nnuru yi di dwuma de yɛ mfonini ho sɔhwɛ ahorow wɔ nuklea nnuruyɛ mu na wɔsa nyarewa bi, titiriw kokoram akisikuru .

Susuw ho hwɛ, sɛ wɔpɛ sɛ wohu sɛ ebia biribi asɛe wɔ wo nipadua mu a, ɛtɔ mmere bi a nnuruyɛfo ma wo aduru kakra nom anaasɛ wɔma wo injection ansa na wɔayɛ scan? Eyi yɛ biribi a ɛte saa. Nnipa a wɔatete wɔn titiriw a wɔfrɛ wɔn nuklea nnuruyɛfo na wɔyɛ nnuru titiriw yi na wɔde ma . Afei , radiologists ne radiologic technologists (RTs) de di dwuma de yɛ mfonini a wɔde hu yare ho nhwehwɛmu. Ɛtɔ mmere bi a, radiation oncologists nso de nnuru yi ma sɛ ayaresa.

Dɛn na wɔde radiopharmaceuticals yi di dwuma?

Wɔde nnuru yi di dwuma titiriw wɔ afã abien. Ma yɛnhwɛ nea wɔyɛ.

1. Radiopharmaceuticals a wɔde hwehwɛ yare mu

Wɔtaa de radiopharmaceuticals di dwuma wɔ nuklea nnuruyɛ mu mfoniniyɛ sɔhwɛ ahorow mu . Yɛfrɛ eyinom "aduru a wɔde hu radiopharmaceuticals." Wɔ United States nkutoo no, wobu akontaa sɛ wɔyɛ nuklea nnuru a wɔsɔ hwɛ yi ɔpepem pii afe biara. Enti wubetumi asusuw sɛnea wɔde di dwuma kɛse no ho.

Saa nhwehwɛmu ahorow yi betumi ahwɛ sɛ akwaa ne ntini a ɛwɔ wo nipadua mu no reyɛ adwuma yiye anaa . Wɔyɛ eyi saa:

Wɔma wo aduru a ɛma anyinam ahoɔden yi kakraa bi pɛ sɛ wobɛnom, ahome, anaa wode ahyɛ wo mu. Ɛtɔ mmere bi a wɔfrɛ eyinom radiotracers . Nnuru dodow a wɔde radioactive bɛma wo no rempira wo. Ɛyɛ kakraa bi pɛ. Saa aduru yi kɔ baabi a ɔhaw bi wɔ wo nipadua mu no na ɛboaboa ano. Afei, mfoninitwa afiri a ɛyɛ mmerɛw yiye, te sɛ gamma mfoninitwa afiri, hu mframa a ɛwɔ wo nipadua mu na ɛyɛ mfonini ahorow a oduruyɛfo no betumi ahu.

Fa no sɛ, saa aduru yi te sɛ detective bi a ɔrekɔ nipadua no mu, hwehwɛ mmeae a ɔhaw no wɔ na ɔkyerɛ yɛn sɛ, "Eha na ɔhaw no wɔ."

Sɛnea wɔde radiopharmaceuticals di dwuma de hu yare no ho nhwɛso ahorow bi ni:

• Fluorine-18: Eyi yɛ radiotracer a wɔtaa de di dwuma wɔ PET scan (Positron Emission Tomography scans) mu.
• Technetium 99m: Eyi ne ade a wɔde radioactive a wɔtaa de di dwuma wɔ nuklea nnuruyɛ mu. Wɔde hwehwɛ nnompe, mmerɛbo dwumadi, ne asaabo dwumadi mu.
• Xenon-133: Eyi yɛ aduru a ɛma anyinam ahoɔden a wohome. Wɔde ma de hwɛ ahurututu mu dwumadi (ahurututu mu dwumadi ho sɔhwɛ).
• Rubidium-82: Eyi yɛ aduru a wɔde fa ntini mu (IV). Wɔde hwɛ sɛnea koma ntini no te (myocardial imaging).

2. Radiopharmaceuticals a wɔde sa yare

Afei ma yɛnka sɛnea wɔde saa nnuru yi di dwuma de sa yare no ho asɛm. Eyinom yɛ soronko kakra wɔ nea wɔde hwehwɛ yare no ho. Radiopharmaceuticals a wɔde sa yare no ma mframa a ano yɛ den yiye na ekum nkwammoaa fi adi . Wɔyɛ eyi de kum nkwammoaa a enni apɔwmuden, titiriw kokoram nkwammoaa .

Saa nnuru yi te sɛ "bounty hunters." Ɛne sɛ, wohu kokoram nkwammoaa na wɔde mframa a wɔde sa yare no kɔ saa nkwammoaa no nkyɛn tẽẽ . Eyi yɛ soronko wɔ external beam radiation therapy , a ɛde afiri di dwuma de mframa a ɛhyerɛn fi wo nipadua akyi kɔ no ho. Nanso saa radiopharmaceuticals a wɔde sa yare yi yɛ adwuma tẽẽ denam nea wɔde wɔn ani asi so no so.

Saa afuw yi, nnuru a ɛma anyinam ahoɔden a wɔde sa yare no yɛ foforo koraa. Nhwehwɛmufo da so ara rehwehwɛ sɛnea wɔde di dwuma foforo mu. Wogye di sɛ radiopharmaceuticals a wɔde sa yare no bedi dwuma titiriw wɔ kokoram ayaresa mu daakye.

Dɛn ne radiopharmaceuticals a wɔde sa kokoram?

``Radiopharmaceuticals`` ahorow pii wɔ hɔ a nnuruyɛfo de sa kokoram. Nhwɛsoɔ:

• PLUVICTO® (lutetium Lu 177 vipivotide tetraxetan): Eyi yɛ aduru a U.S. Aduan ne Nnuru Dwumadibea (FDA) apene so. Wɔde sa prostate kokoram (PSMA-positive metastatic castration-resistant prostate cancer - PSMA-positive mCRPC).
• LutatheraTM `(LutatheraTM - Lutetium Lu 177 aduru a wɔde yɛ aduru)`:Eyi nso yɛ aduru a FDA apene so. Wɔde sa ntini mu akisikuru bi (somatostatin receptor-positive gastroenteropancreatic neuroendocrine tumors) a ɛba yafunu, dwensɔtwaa, ne dwensɔtwaa mu.
• Iodine-131: Eyi ne ɔkwan titiriw a wɔfa so sa radioactive iodine. Ebetumi asa thyroid kokoram binom ne Graves yare a wɔsan frɛ no hyperthyroidism no bi.
• Radium-223: Eyi tu mpɔn yiye wɔ nnompe mu akisikuru a ɛba bere a prostate kokoram trɛw (ɛtrɛw) kɔ nnompe no mu no mu. U.S. FDA apene Radium-223 dichloride (XofigoTM) so sɛ wɔmfa nyɛ eyi.

Afei nso, mprempren wɔreyɛ radiopharmaceutical ayaresa ahorow pii a wɔde sɔ kokoram ahorow afoforo hwɛ wɔ ayaresabea .

Dɛn ne nnuru a wɔde yɛ radiopharmaceuticals a wɔtaa de di dwuma?

Sɛnea yɛadi kan aka no, Technetium-99m yɛ radiopharmaceutical a nnuruyɛfo taa de di dwuma. Wɔde di dwuma titiriw ma mfoninitwa nhwehwɛmu a wɔde hu yare no. Ɛboa ma "wohu" nea edidi so yi:

• Pulmonary perfusion (mogya a ɛsen) w’ahurututu mu.
• Mogya a ɛsen fa wo ntini mu (Vascular perfusion).
• Nnompe.
• Myocardial ntini a ɛwɔ nipadua no mu.
• Nsu a ɛma nusu.
• Thyroid ntini a ɛwɔ nipadua no mu.

Nnuru afoforo bi a wɔtaa de di dwuma wɔ radio so ne:

• 18F Fluorodeoxyglucose `(18F Fluorodeoxyglucose - FDG)`
• Gallium-68 NKYERƐKYERƐMU
• Gallium-68 PSMA `(Gallium-68 PSMA)`
• 18F PSMA `(18F PSMA)`
• Iodine 123 `(Iodine 123)`

Enti so radiopharmaceuticals yi yɛ nea asiane biara nni ho ankasa?

Eyi yɛ asɛmmisa a nnipa pii wɔ. Sɛ wɔde radiopharmaceuticals di dwuma na wɔhwɛ so yiye a, asiane biara nni ho. Wo radiologist ne/anaasɛ radiation oncologist ne nuklea nnuruyɛfo bɛyɛ adwuma de ahwɛ ahu sɛ radiopharmaceutical dodow a wɔde ma wo no teɛ na ahobammɔ wom . Enti biribiara nni hɔ a ɛsɛ sɛ ɛhaw yɛn ho.

Te sɛ nnuru nyinaa no, mframa a wɔde sa yare betumi de ɔhaw ahorow bi aba . Nanso, mpɛn pii no, mfaso a ɛwɔ aduru no so no dɔɔso sen asiane a ɛwɔ mu no. Wo duruyɛfo bɛkyerɛkyerɛ saa nsunsuanso bɔne a ebetumi aba yi mu akyerɛ wo ansa na woafi ayaresa ase.

Ɛwom sɛ wɔde radiopharmaceuticals adi dwuma mfe du du pii wɔ nuklea nnuruyɛ mu mfoninitwa mu de, nanso nnansa yi ara na wɔafi ase de adi dwuma de asa kokoram. Nhwehwɛmufo da so ara resua sɛnea nnuru a ɛma anyinam ahoɔden yi de wɔn ani si kokoram nkwammoaa so na wokunkum wɔn no ho ade. Sɛ w’ani gye ho sɛ wubesua nnuru a wɔde sa kokoram a wɔde sa kokoram a wɔsɔ hwɛ wɔ ayaresabea ho ade a, wo ne wo duruyɛfo nkasa. Wɔn ani gye sɛ wɔbɛboa wo.

Nea etwa to no, nneɛma a ɛho hia sen biara a ɛsɛ sɛ wokae

Okay, enti, sɛnea yɛaka ho asɛm no, eyinom ne nneɛma atitiriw a ɛsɛ sɛ wokae:

• Radiopharmaceuticals yɛ aduru titiriw bi a ɛhwɛ radioactivity so .
• Wɔde eyinom di dwuma titiriw de yɛ mfonini a wɔde hu (e.g. PET scans, bone scans) ne de sa nyarewa bi, titiriw kokoram .
• Wɔ diagnostics mu no, eyinom yɛ adwuma sɛ ``Radiotracers'', "ɛkyerɛ" nipadua no mmeae a ɔhaw ahorow wɔ.
• Wɔ ayaresa mu no, eyinom boa ma wɔde wɔn ani si kokoram nkwammoaa so na wɔsɛe wɔn .
• Saa nnuru yi yɛ nea asiane biara nni ho bere a wɔde ma wɔ oduruyɛfo hwɛ a ɛfata ase no . Sɛnea ɛte wɔ nnuru nyinaa ho no, ebia nsunsuanso nketenkete bi bɛba, nanso mpɛn pii no mfaso a ɛwɔ so no boro so.
• Saa adwuma yi, titiriw wɔ kokoram ayaresa mu no, da so ara renya nkɔso , na wobetumi ahwɛ nkɔso foforo pii kwan daakye.

Enti, bere foforo a wobɛte ``(Radiopharmaceutical)'' ho asɛm no, afei woanya ntease pa wɔ nea ɛyɛ ne nea wɔde di dwuma ho, ɛnte saa? Sɛ wowɔ nsɛmmisa foforo biara a, ntwentwɛn wo nan ase bere nyinaa sɛ wubebisa wo duruyɛfo.
