If you or your child need an MRI, that is, an MRI, you should know that the procedure is safe.
Many people will never need to have an MRI scan, and if you have a cochlear implant, there may be other diagnostic tools available to use. In fact, 85% of radiology professionals agree that they have an alternative diagnostic tool for those who cannot undergo magnetic resonance due to having a device or a magnet implant.
Magnet removal for better head and neck MRI studies
If you must undergo an MRI scan of the head, the presence of the cochlear implant magnet will distort the MRI scan image of any power. Regardless of what brand of implant you have, for the MRI scans of the brain in general you need to remove the magnet.
You can remove and replace the implant magnet with a medical procedure if necessary. In the unlikely event that you or your child need repeated MRIs, there is an option without a magnet.
Neuroimaging: Role of MRI
Magnetic resonance imaging can produce not only morphological images but also functional ones and its range of indications is extended day by day, invading the terrain of other modalities (CT, angiography, PET, ultrasound, etc.). There are currently two techniques in MRI that are leading the research, functional magnetic resonance imaging (MRI).
Determining the merits of a given medical imaging test poses a complex and multidimensional problem. In fact, the merits of an examination may depend on the patient's age, sex, size and physical limits. It may also depend on the disorder and symptoms under review
Making good decisions about medical imaging is further complicated by the fact that imaging techniques are evolving rapidly and that some clinical cases and exams are difficult. Furthermore, understanding the rationale for prescribing practices for diagnostic imaging exams is further complicated by an increasing trend in the number of specialists (e.g. cardiologists, obstetricians, rheumatologists, neurologists and oncologists) who order diagnostic imaging tests and interpret images and, in some cases, run imaging laboratories.
The use of advanced diagnostic imaging is likely to continue to increase over the next decade due to the above factors. Other factors may also contribute to the continued growth in the use of advanced diagnostic imaging. For example, the increased use of CT may be due in part to the interest it has had as a screening tool, particularly for lung cancer in smokers and former smokers, heart disease and colon cancer.
Similarly, it is likely that PET/CT will play an increasingly important role, as new radioactive indicators will broaden the range of clinical disorders that it can diagnose. It remains to be seen whether this possible increase in use will result in an increase in the frequency of inappropriate use.
