Magnetic Resonance Imaging (MRI)


Magnetic Resonance Imaging (MRI) is a highly advanced medical imaging technology for showing images of various tissues and organs in different planes after computer reconstruction. MRI scan uses a powerful magnetic field and radio waves to produce images. Doctors can then make a more accurate and thorough diagnosis. It can provide extremely high-resolution medical images without ionising radiation, although an MRI scan is often costly.


Examination Process


The examination time takes 30 minutes to 2 hours, depending on the type of examination. Before the examination, our radiographer will explain examination procedure and ask about past medical history. Before entering the MRI scanning room, he/she will use a metal detector to check if there is any removable metal on the patient's body. During examination, the patient is asked to lay on the table and slowly move into the bore. Radiographer may place coils on top of patient's body to enhance signal receiving. Due to rapid change of gradient strength, the patient will hear noise in different tones and frequencies.  Earplugs will be provided for protection. A call bell will be given, in case of any emergency situations, the patient can still talk to our radiographer outside the examination room.
