Stainless steel embolic AGENTS |
Devices made of stainless steel include some old coils, Amplatz Vascular Obstruction Device (Vascular Spider, discontinued), Amplatzer Vascular Plug, and core-removed guidewires used as embolic agents for massive lesions (e.g. PTFE-Coated, Bentson, etc by Cook, Boston Scientific, and others).
In general, stainless steel coils are MR Conditional. Patients with this coil may be scanned safely any time after placement under the following conditions: 1- Static Magnetic field ≤ 3.0 tesla 2- Maximum spatial magnetic gradient ≤ 1,600 gauss/cm 3- Maximum MR system reported, whole-body-averaged specific absorption rate (SAR) ≤ 2.0 W/kg normal operating mode for 15 minutes of scanning or less (i.e., per scanning sequence). Heating from stainless steel coils produced a maximum temperature rise of 1.8 °C during 15 minutes of MR imaging (i.e., for one scanning sequence) in a 3 tesla MR at an MR system reported whole-body-averaged SAR of 2.9 W/kg. Image Artifact may occur within ~ 75 mm of the stainless steel coil. Therefore, it may be necessary to optimize MR imaging parameters. Core-removed guide wires: Not rated. Marked MRI artifacts and image deterioration were noted in 2 of our patients with implanted stainless steel core-removed guidewires. There were no complications but the exams were terminated due to very poor image quality. ** Conditional 5, 6, and 8: Patients with this device can be scanned safely immediately after placement under the following conditions: -Field ≤ 3 Tesla, Maximum SGMF ≤ 720-Gauss/cm, and MR whole-body SAR ≤ 3 W/kg for 15 minutes pulse sequence. Heating ≤ 4.0 degrees C. In Conditional 5, artifacts may compromise the image relative to the size of the device. Conditional 8 is labeled at 1.5-Tesla and 3-Tesla Only. Artifacts may compromise the image relative to the size of the device or be slightly larger. Source: MRISafety.com |
