The telediagnosis of double aortic arch using spatio-temporal image correlation.

We diagnosed two cases of double aortic arch (DAA) remotely. In both cases, the right aortic arch was suspected, and a remote diagnosis was requested. We performed a remote diagnosis by the spatio-temporal image correlation (STIC) method. DAA was diagnosed by detecting the left aortic arch in an axial transverse section in the three-vessel trachea view. Since the STIC method can make multiple cross sections, making a diagnosis by the STIC method was useful for the remote diagnosis of these patients. In particular, HD flow render mode clearly showed left aortic arch, so it was possible to diagnose DAA.
