[A recent research publication in PLoS ONE has described a new 3T MRI sign of Parkinson's disease known as the 'absent swallow tail sign'. The discovery, which has the potential to revolutionize the diagnosis of this important disease, uses axial high resolution susceptibility weighted imaging (SWI) to assess the structure of the substantia nigra within the midbrain....
...In Parkinson's disease, the high SWI signal within nigrosome-1 is lost and the normal 'swallow tail sign' cannot be identified (Figure 1B - Parkinson's disease). The researchers found that absence of the swallow tail sign had a diagnostic accuracy of greater than 90% for Parkinson's disease. http://radiopaedia.org/blog/new-tell...insons-disease
