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

What is the MRI ACR Phantom, Medium used for?

The MRI ACR Phantom, Medium is a quality assurance tool used to test and calibrate MRI scanners according to ACR (American College of Radiology) accreditation standards. It helps technologists verify image accuracy, detect system drift, and evaluate geometric distortion, slice thickness, spatial resolution, low-contrast detectability, and signal-to-noise ratio (SNR). It’s essential for maintaining reliable image quality and ensuring compliance with ACR, AAPM, and IPEM MRI performance guidelines.

Is the MRI ACR Phantom, Medium MR Safe for use inside the scanner bore?

Yes. This phantom is MR Safe, meaning it contains no ferromagnetic or conductive materials and presents no known hazards in any MRI environment. It can be safely positioned inside the bore during imaging sequences without affecting the magnetic field or causing artifacts. The design and labeling meet ASTM F2503 standards for MR Safe devices.

How is the Medium ACR Phantom different from the Large model?

The Medium ACR Phantom measures 7 inches in diameter, making it slightly smaller and easier to handle than the 8-inch Large Phantom. It’s ideal for facilities that need precise QA testing in systems with more compact coil setups or limited bore space. Both models are functionally equivalent and comply with ACR MRI Accreditation and AAPM Reports 28, 34, and 100 for MRI acceptance and QA testing.

What tests can I perform using this ACR MRI phantom?

You can use the MRI ACR Phantom, Medium to perform a complete range of MRI system quality control tests, including geometric distortion and spatial resolution, slice position and thickness accuracy, image uniformity and low-contrast detectability, signal-to-noise ratio (SNR) and water–fat shift measurements, electronic and physical slice offset checks. Each phantom includes a detailed instruction manual with ACR-compliant test procedures and result interpretation guidelines.

How is the MRI ACR Phantom shipped, and what should I know before ordering?

MRI Med typically ships stocked QA products like this phantom within 48 business hours (Monday–Friday, PST). The Phantom Case (PC-138) is available separately for secure storage and transport. An import tariff surcharge applies at checkout. Returns are accepted for unused items within 30 days of shipment, with prior approval required. Any damage or shortage must be reported within 48 hours to MRI Med and the carrier.
