Many patients who have had Lyme disease struggle with cognitive challenges, even after treatment. This new imaging study shows changes in white matter that might explain these symptoms.
Automated tractography pipeline with diffusion MRI measures traumatic axonal injury in severe traumatic brain injuries.
Purpose: To assess the technical performance of the apparent diffusion coefficient (ADC) on a dedicated 3T radiotherapy scanner, using a standardized phantom and sequences. Investigations into factors that could impact the technical performance of ADC in the clinic were also completed, including changing the slice-encoded imaging direction and the reference sample ADC value. Methods: ADC acquisitions were performed monthly on an isotropic diffusion phantom over 1 year. Measurements of ADC %bias, coefficients of variation for short-/long-term repeatability and precision (CVST/CVLT and CVP), and...
