Ni, aku cedok dari website lain.
A positron emission tomography (PET) scan is a unique type of imaging test that helps doctors see how the organs and tissues inside your body are actually functioning.
The test involves injecting a very small dose of a radioactive chemical, called a radiotracer, into the vein of your arm. The tracer travels through the body and is absorbed by the organs and tissues being studied. Next, you will be asked to lie down on a flat examination table that is moved into the center of a PET scanner—a doughnut-like shaped machine. This machine detects and records the energy given off by the tracer substance and, with the aid of a computer, this energy is converted into three-dimensional pictures. A physician can then look at cross-sectional images of the body organ from any angle in order to detect any functional problems.
A PET scan can measure such vital functions as blood flow, oxygen use, and glucose metabolism, which helps doctors identify abnormal from normal functioning organs and tissues. The scan can also be used to evaluate the effectiveness of a patient’s treatment plan, allowing the course of care to be adjusted if necessary.
Currently, PET scans are most commonly used to detect cancer, heart problems (such as coronary artery disease and damage to the heart following a heart attack), brain disorders (including brain tumors, memory disorders, seizures) and other central nervous system disorders.
Ni lah mesin scan tu. Lebih kurang macam CT scan biasa juga. Bezanya sebelum scan, aku diberi radioactive chemical yang diinjek ke dalam salur darah. Lepas tu, aku diminta untuk baring, kurangkan pergerakan dalam masa 45 minit ke sejam camtu. Masa scan tu dalam 20 ke 30 minit. Waktu nak dimasukkan contrast dalam salur darah (sebelum scan kena insert branula kat tangan) rasa pedih sebab contrast tu pekat dan kena masuk 3ml per second. Menjerit jugakla dalam hati sebab tengah scan mana boleh bergerak. Walaupun beberapa saat saja masa untuk auto inject contrast tu, sakit tu.. haish.. rasa panas ngan kebas kat tangan. Bila contrast tu dah start berjalan dalam badan, oklah. Hilang sakit tu.
Badan dah diinjek dengan bahan radioaktif. Maka aku adalah umpama radioaktif bergerak selama 24 jam. Tak boleh duduk dekat dengan orang lain. Takut memudaratkan orang. Paling kesian anak-anak la. Kesian, boleh tengok saja tapi tak boleh pegang. Dah habis tempoh 24 jam, apa lagi, kena 'gomoi' la anak-anak aku tu. Hehe..
Pernah juga buat PET-CT masa breasfeeding dulu. Ini yg paling kesian, dah la tak boleh pegang, menyusu jauh sekali la. Pam dan buang saja. Paling sedih tengok anak tu. Hilang nenen, dengan mama sekali untuk satu malam. Esoknya, lepas geram la dia. Hehe..
Staf kat kaunter PET-CT tu pun dah cam aku. Masa nak register, tengok muka ja, tak perlu bagi nama. Iye lah, aku kan regular customer kat situ. Hehe..
