Kawasumi Najuta Thoracic Stent Graft System

MRI Information

The results of nonclinical study under the prescribed conditions of using MRI equipment, Twin Speed 1.5T, manufactured by GE indicate that this stentgraft is compatible with MR imaging. The conditions are described as follows:

・Magnetic field intensity: 1.5 T (tesla)
・Gradient field: 400 G (gauss)/cm
・MR imaging for 15 minutes or shorter at specific absorption rate (SAR) of 3.77 W/kg

・As a result of the MRI shooting in the nonclinical study with 3 stentgrafts overlapped done in the nonclinical study under the MRI shooting conditions described above, an temperature increase of the stent section 3.19 degrees or less is observed

・An artifact of up to 16.5 cm is observed at the edge of the stentgraft as a result of the assessment of image artifacts in the nonclinical study under the MRI shooting conditions described above.
