Spee-D-Mark MRI Skin Marker is easily identifiable- clearly and accurately communicates an area of interest or concern to the radiologist. Perfect for large areas like abdomen and spine scans. The MRI skin marker is 100% latex-free and hypoallergenic safe for patients. Also does not indent the skin, preventing a compromised image. It is artifact-free which helps generate artifact-free images, resulting in reduced retakes.
