Magnetic Resonance Imaging

Esok pagi i kena pi Hosp. Serdang sbb nak buat MRI (Magnetic Resonance Imaging). Dengar mcm teruk sangat kan. Actually i'm having problem with my left ear. Kadang2 ok tp kadang2 mcm i dengar perlahan sangat. Pakar kat Putrajaya dah checked tp physically telinga i looks normal. So dia rasa mungkin i ada problem dgn nerve. Reason i kena buat MRI sbb nerve problem on older people is normal but on me? umur i baru 26 thn..Sbb tu la i kena buat scanning tu just to confirm je..So, start 12 tgh mlm ni i kena puasa sampai la esok pagi.

So, what is MRI?

An MRI (or magnetic resonance imaging) scan is a radiology technique that uses magnetism, radio waves, and a computer to produce images of body structures. The MRI scanner is a tube surrounded by a giant circular magnet. The patient is placed on a moveable bed that is inserted into the magnet. The magnet creates a strong magnetic field that aligns the protons of hydrogen atoms, which are then exposed to a beam of radio waves. This spins the various protons of the body, and they produce a faint signal that is detected by the receiver portion of the MRI scanner. The receiver information is processed by a computer, and an image is produced.

The image and resolution produced by MRI is quite detailed and can detect tiny changes of structures within the body. For some procedures, contrast agents, such as gadolinium, are used to increase the accuracy of the images.

Macam takut je dengar kan..Anyway the machine will probably look like this..

Tengok la esok camne..will update later k
