This sound relates to the movement of blood within your heart chambers. The images are constantly viewed on the monitor and recorded for a permanent record of the examination. This is reviewed by the physician prior to completion of the final report. Other than wearing loose-fitting clothing, there are no special restrictions or preparation prior to a 2D Doppler echocardiogram. Although the gel is water soluble and should not stain; it is messy and could get on your clothing so please be aware and dress appropriately.

It is very important that you keep your appointment once it is scheduled. If you must cancel your appointment, please give the office at least 24 hours notice by calling Our testing schedule requires tight time restrictions, so please notify the office immediately if you will be late for your appointment.

We appreciate your complete cooperation. The ordering physician will then review the results and discuss them with you. You may be trying to access this site from a secured browser on the server.

A single capillary is a mere microns in diameter -- so small that red blood cells must flow through in single file. SC-OCTA works by combining spectroscopy, which looks at the various visible light wavelengths, or color spectra, with conventional optical coherence tomography OCT , which is similar to ultrasound except uses light waves instead of sound waves.


Like a radar, OCT pinpoints the tissue of interest, and then spectroscopy characterizes it. SC-OCTA has many advantages over traditional imaging: it does not rely on injected dyes for contrast or harmful radiation. Many types of imaging also only work if the area of interest is moving for example, ultrasound can only image blood when it is flowing or completely still. This enables it to image stagnant blood or moving organs, such as a beating heart.

The new technology's only limitation is that it cannot image deeper than 1 millimeter.

This might seem shallow compared to ultrasound, which can see several centimeters below the surface. Backman said this can be remedied by putting the tool on the end of an endoscopic probe. By inserting it into the body, the tool can image organs up-close.
