Tract density imaging values were significantly decreased after magnetic resonance-guided focused ultrasound in the genu of the corpus callosum and left globus pallidus of seven patients with Parkinson’s disease.
Figure 3. The brain areas with significantly decreased track density values postoperatively, overlaying on the T1 template. A) Left globus pallidus and B) genu of the corpus callosum. The color bar represents the t-value of the T-test.
Figure 1. The A) fractional anisotropy (FA) and B) track density image (TDI) from the same patient. TDI has a higher spatial resolution than that of the FA image (1 × 1 × 1 mm3 vs 2.2 × 2.2 × 2.2 mm3, respectively).
