There is a new technology that helps detect one of diabetes' most harmful complications. It is called DDOT or dynamic diffuse optical tomography. It is a non-invasive, light-based imaging modality developed by researchers at Columbia University that will allow clinicians to diagnose and monitor peripheral artery disease in individuals with diabetes more accurately.
Currently, non-invasive diagnostic methods for detecting PAD (Peripheral Artery Disease) are limited to ankle-brachial index or ABI and lower-limb duplex ultrasound which may not reveal the full picture of blood flow in the extremities in some cases.
DDOT may give clinicians the clearest picture yet of the quality of blood flow in a patient's extremities by obtaining a direct measure of the distal perfusion rather than the surrogate ones yielded by the previously mentioned modalities. This is accomplished by a near-infrared optical tomography imager to send light through optical fibers into the tissue of the foot via a measuring probe placed around the foot.
If you suspect yourself or someone you know may be suffering from PAD, please make an appointment by calling (512) 328-8900 to determine your risk of complications from this condition. The doctors at Austin Foot and Ankle Specialists are experts in the diagnosis and detection of PAD.
