MR Safe What does this mean?
MR Safe

MR Safe – an item that poses no known hazards in all MRI environments. Using the terminology, “MR Safe” items are non-conducting, non-metallic, and non-magnetic items such as a plastic Petri dish. An item may be determined to be MR Safe by providing a scientifically based rationale rather than test data.

MR Conditional

MR Conditional – an item that has been demonstrated to pose no known hazards in a specified MR environment with specified conditions of use. “Field” conditions that define the MR environment include static magnetic field strength, spatial gradient magnetic field, dB/dt (time rate of change of the magnetic field), radio frequency (RF) fields, and specific absorption rate (SAR). Additional conditions, including specific configurations of the item (e.g., the routing of leads used for a neurostimulation system), may be required.

MR Unsafe

MR Unsafe – An item that is known to pose hazards in all MRI environments. MR Unsafe items include magnetic items such as a pair of ferromagnetic scissors.

Frequently Asked Questions

1. Are Multi-Modality Markers suitable for MRI use?

Yes. Multi-Modality Markers are made from non-metallic, non-conductive materials and are MR Conditional for use in 1.5T and 3T MRI environments. They maintain visibility across all MRI sequences without creating distortion, signal loss, or heating, allowing for safe use during active scanning.

2. What makes Multi-Modality Markers different from standard MRI skin markers?

These markers are designed for multi-modality imaging—they show up clearly on MRI, CT, X-ray, and mammography. The hydrogel structure and center passage hole make them useful for biopsy guidance, lesion localization, and cross-modality correlation, helping radiologists and technologists align and compare results from multiple imaging systems.

3. How does the hydrogel design help with image quality?

The hydrogel material prevents tissue indentation and eliminates artifact formation. It conforms smoothly to the skin surface, producing a clean, consistent signal across modalities. This helps maintain precise anatomical alignment and minimizes shadowing or distortion in high-resolution MRI and CT scans.

4. How are these markers applied and removed?

Each marker uses a medical-grade adhesive that holds securely during imaging but removes easily without residue or skin irritation. To apply, place the marker on clean, dry skin, ensuring full contact. The design includes a central hole for needle placement, ideal for interventional or biopsy procedures. Markers are single-use and supplied 50 per box.

5. What are the dimensions and visibility features of Multi-Modality Markers?

Each marker measures 15 mm in outer diameter and 3.5 mm thick, with a 5 mm axial hole and 2 mm center hole. They produce a bright, well-defined reference point on all imaging systems, ensuring clear localization for radiologists during multi-modality studies and follow-up scans.
