What the Extra Inch Does for Positioning
Pick the 6x4x2 when you need real height. Two inches under the knees gives the lower back some relief during a long supine scan. The same block under an ankle raises the foot clear of the table for a lateral view, and between the arm and the torso, it keeps the arm from pressing against the body during a shoulder or elbow study. When you only need a small correction, the 6x4x1 rectangle sponge is the better fit, and the two stack when a setup calls for 3 inches.
Made for the Magnet Room
The MR Safe label tells you the block holds no metal and no conductive or magnetic material. Inside the field it does not heat, pull, or cast artifact on the image, so your MRI team can keep it in the scanner room full time instead of swapping supports at the door.
Built for High-Volume Rooms
- Heavy-duty closed-cell foam holds its shape under repeated compression through daily use.
- The foam is non-porous, so blood, contrast, and cleaning solution stay on the surface rather than soaking in.
- It is radiolucent, so it leaves no shadow on X-ray or CT images.
- Two inches of firm foam gives the lift a thin pad cannot, without the bulk of a full bolster.
- The non-coated surface wipes down with standard disinfectant and dries quickly since nothing soaks in.
- Charcoal grey foam hides the marks that show on lighter pads, and the block is light enough to reposition with one hand.
Uses in MRI, X-ray, and CT
You get flat lift and separation in every imaging room. In MRI, the block raises a knee, supports an elbow, or props the head in a neutral position. In X-ray and CT, it lifts an extremity for a lateral or oblique view and stays invisible on the image. Pair it with the MR Safe wedge set when you need an angle instead of flat height.
Cleaning Between Patients
Spray or wipe with your standard surface disinfectant and let it dry. Closed cell foam does not wick fluid the way open cell foam does, so there is no soaked core holding contamination between exams. That is why closed cell is the better choice for infection control. Keep it on the shelf with your other positioning sponges so it is within reach for the next setup.
Frequently Asked Questions
What is the difference between the 6x4x2 and the 6x4x1 sponge?
Thickness. Both share the same 6 by 4 footprint and the same MR Safe closed cell foam. The 6x4x2 gives 2 inches of lift for knees, ankles, and larger gaps. The 6x4x1 gives 1 inch for smaller corrections. You can stack the two when a setup calls for 3 inches.
Can I use this sponge inside the MRI scanner room?
Yes. It carries the MR Safe label, so it holds no metal or magnetic material and can stay in the scanner room and near the bore.
Does the foam absorb blood or contrast?
No. The closed cell structure keeps fluid on the surface, so you wipe it off rather than replace the sponge.
How do I choose between this block and a wedge?
Use the rectangle when you need a flat lift. Use a wedge when you need an angle, such as tilting a limb or opening a shoulder. For MRI work, the MR Safe wedge set covers the angled jobs.
