MRI is unsuitable for:
(All of the above) (19-Sutton 7th)MAGNETIC RESONANCE IMAGINGADVANTAGESDISADVANTAGES* It is non-invasive technique* It is safe as it does not involve the use of ionising radiation* There is no adverse biological effect.* Images can be readily produced in any plane eg. Axial sagittal or coronal without changing position of the patient* It gives high intrinsic contrast* Very high cost of imaging* Inability to image bone and calcium* It is unsuitable for patients with cardiac pacemakers and other ferromagnetic implants.* Imaging time is long, hence movement or motion artifacts are quite like.* Highly operator dependent, hence require technical expertise
