Kangaroo feeding tube with
IRIS technology
MR Unsafe
MR Conditional
The Kangaroo feeding tube with IRIS technology was
determined to be MR Conditional. Do not bring MR
Unsafe items into the MRI scan room. This includes all
components and accessories of the Kangaroo system
(console, interface cables, stylet, etc.) other than the
Kangaroo feeding tube with IRIS technology.
Non-clinical testing demonstrated that the Kangaroo
feeding tube with IRIS technology is MR Conditional.
A patient with this device can be scanned safely,
immediately following positioning of this feeding tube
under the following MR Scan Conditions:
• Static magnetic field of 1.5 or 3.0 Tesla
• Maximum spatial gradient magnetic field of 3,700-
gauss/cm (37 T/m)
• Maximum MR system reported, whole-body
averaged specific absorption rate (SAR) of <2 W/kg
(Normal Operating Mode).
MRI-related heating:
Under MR Scan Conditions defined above, the
Kangaroo feeding tube with IRIS technology is
expected to produce a maximum temperature increase
of 1.5°C after 15 minutes of continuous scanning.
These temperature changes will not pose a hazard to a human subject under the
conditions indicated above.
Artifact Information
MR image quality may be compromised if the area of interest is in the exact same
area or relatively close to the position of the Kangaroo feeding tube with IRIS
technology. Therefore, optimization of MR imaging parameters to compensate for the
presence of this device may be necessary. The maximum artifact size (i.e., as seen on
the gradient echo pulse sequence) extends approximately 10-mm relative to the size
and shape of this device.
Additional instructions or information essential to safe use in the MR Environment:
The stylet must be removed from the Kangaroo feeding tube with IRIS technology
prior to permitting the patient to enter the MR system room to undergo an MRI
examination.
Applied part definition:
Per IEC 60601-1 Ed. 3.1, the applied part of this system is the Kangaroo feeding
tube with IRIS technology. The feeding tube with IRIS technology is detachable ME
equipment intended to receive power from the Kangaroo console.
