Weight-Bearing CT Imaging

Weight-Bearing CT Imaging

The American Orthopedic Foot & Ankle Society recommends standing (weight bearing) imaging, when possible, to get the most accurate assessment of the functional bony anatomy of the lower extremities. Deformities of the forefoot, midfoot and hindfoot, as well as meniscal position in the knee, are shown to be more visible in weight bearing. Your doctor may order a standing scan to supplement your X-Rays. The CT scan takes less than 30 seconds, delivers low radiation dose, and provides your doctor with three dimensional views of the lower extremities.

NextStep Foot & Ankle Centers is proud to introduce our new CurveBeam Extremity 3D Imaging to our South County location. This new weight bearing CT will conduct a more accurate alignment-dependent condition diagnosis. The CT will provide 3D views of morphology, alignment and joint space, leading to a better overall treatment plan. The CurveBeam Weight Baring CT three-dimensional imaging helps ensure the right diagnosis the first time!

What is the Curve Beam CT?
Computed tomography (CT) technology acquires and combines multiple X-Ray projections to create a three-dimensional true representation of bones and joints.

How is a Standing CT Scan Taken?
To get a standing CT scan, you step on to a circular platform. The platform is about 2 inches off the ground, and there are handlebars on either side of the platform to assist you. There is a cushioned seat attached to the back of the system in case you are unable to stand. You stand in place as the entry doors, which are not taller than the height of an average person’s knee, close in front of you. The operator will start the scan, and you will be asked to stay completely still for 30 – 60 seconds. Then the doors will re-open and you will be able to step out.

How is a Standing CT Scan Different from a Traditional CT Scan?
Traditional computed tomography requires patients to lie still on a table, which slides into the center of the CT scanner. When a scan is taken in the standing position, physicians can evaluate alignment of the bones and joints. For example, physicians can clearly see if the ankle is rotated out of position, or if joint space is compromised in the midfoot. In a traditional CT scan, the foot is in a relaxed position. Although there are methods to “simulate” the standing position while the patient is lying on a table, the best way to evaluate foot and ankle biomechanics is to have the patient stand. Standing CT uses cone beam CT technology, which means the X-Ray tube only needs to make one revolution around the foot & ankle to capture the entire region of interest.


Why should YOU get a weightbearing CT scan?

• Quick Scan – Take less than 48 seconds a scan.
• Affordable – Most commercial insurances are accepted. Medicare is accepted too!
• Precise Measurements
• High definition
• Low radiation – A bilateral foot scan from our system is a fraction of the radiation compared to a traditional CT.
• 3D Dimensions
• Analysis of the foot arch support.
