MRI scan also has disadvantage which it is
done in an enclosed space, so the people who are claustrophobic (fearful of
being in a closely enclosed surface) are facing problems with MRI to be
finished. Estimate suggest that as many as one in six patients experience the
ill effect of claustrophobia in an MRI machine and can’t go through it.
Moreover, the machine has limitation to how big a patient can be. Then , If a
patient is suffering from severe back pain, neck pain or other symptoms, lying
still for a prolonged period may not be well tolerated.
To overcome this problem ‘open’ MRI scanner
should be developed where the patient sits or stands with the scanning
equipment (which contains the large magnets) set on
either side of them. There is a gap at the front, not only does this expel the
risk of claustrophobia, but it means patients can even watch a diverting DVD on
a screen in front of them. In addition to that, its not only profiting those who dislike being enclosed, it also can
accommodate bigger patients who are essentially not able to fit into an
ordinary machine.
To
further decrease scanning time, we suggest to implement a technique called
compressed sensing. Compressed sensing decreases filter times by
social affair just a little portion of the information customarily expected to
empower reproduction of an entire attractive reverberation picture; this is
called under-examining. The way to the strategy is a unique calculation
utilized after the sweep that can recreate the full MR picture from these
couple of information focuses with high constancy.
For children , such a feat is
nearly impossible during the processed. In addition, the confined space of the
MRI machine joined with the loud noises it creates can upset children, making
it even more difficult for them to remain still. Moreover, young kids
experiences difficulty holding their
breath on command. To prevent from causing image distortion, we need to make
sure that there is no movement of the chest and abdomen. So we suggest to build
MRI Signal-receiving coils that are designed to maximize the amount of true
signal that is received while minimizing the noise or interference. However ,
standard coils are regularly bigger than needed for children and pick up extra
noise , causing image to become less sharp. While the reduced size of the coils improve image clarity.
Lastly , MRI scan is a
painless and safe scan that produces clearer images of the body and its
tissues, at any angle. So we recommended that this machine should always be
upgraded to give us a better image of how our body and the brain works than
ever before. So it will be useful for doctor to detect some diseases like brain
tumour or cancer and allowing much more effective surgery.
very interesting blog :) thanks for the information
