Comparison of Cochlear Implant Magnets and Their MRI Artifact Size

Table 2

Individual measurement at 3 T.

		Distance of measurement	AB		Medel
			Ipsilateral	Contralateral	Ipsilateral	Contralateral
	Area of measurement	in cm
Volunteer 1	Hard artifact		3	8.5	3	8.9
	Soft artifact		5.3	10.9	5.3	11
	Survey sagittal		5.8		5.8
Volunteer 2	Hard artifact		4.1	13.4	4	13.3
	Soft artifact		6	11	5.8	10.6
	Survey sagittal		5.8		5.7

The table shows each measurement for each brand in terms of estimation (ipsilateral and contralateral) and the differentiation between soft and hard artifact. In addition, the survey calculation is added.
