Now available, the Hallmarq Standing Equine MRI! This is the only unit of its kind in this part of the Midwest, and it will prevent horses from having to ship several hours for this level of diagnostic imaging. Since the horse is standing during the procedure, the scan is safer and faster than units using general anesthesia.

Frequently Asked Questions about sMRI:

Q. How much does the MRI cost?
A. The price for the MRI is $1800 for 1 site. This is most commonly both front feet, including the fetlocks if needed. The price includes sedation, hospitalization and operator time. No additional costs are charged over the $1800.

Q. Does insurance cover the MRI?
A. Yes, major medical insurance typically covers the MRI at either 50 or 100%.

Q. Where is the unit located, or is it portable?
A. Although Yates Equine is a mobile practice, the MRI is not portable. The MRI is permanently installed at Dr. Yates's personal farm that is located on the south side of Indianapolis, about 2 miles south of 465, between the SR 37 and US 31 exits.

Q. Which parts of the horse can be scanned in the standing MRI?
A. Feet, up to and including the fetlock, are typically the most common parts of the horse scanned. However, the magnet may be raised out of the floor to reach approximately mid-forearm (radius) and mid-gaskin (tibia). This allows for knees, hocks and suspensories to be scanned if x-ray or ultrasound is not giving an answer on the lameness.

Q. What is the difference between an MRI and a CT (CAT scan)?

A. A CT uses radiation to give a 3D image of a structure and is especially good for diagnosing bone injuries, such as fractures. An MRI uses a magnet and radiowaves to develop a 3D image. MRI imaging is known to be superior to CT for tendon and ligament imaging.

Q. Is the MRI the same thing as a bone scan (nuclear scintigraphy)?

A. No, a bone scan involves injecting the horse with a radioactive substance bound to phosphate, which is then incorporated into bone. A gamma camera is able to detect areas of increased uptake of the radioactive phosphate to show where bone remodeling (inflammation or injury) is occurring. A bone scan is usually done to find the general area of a lameness when it is impossible to use nerve blocks (a neck or pelvic injury for example). After the lameness is localized, then x-rays, ultrasound and MRI can be used to determine what is causing the lameness.
