Summary Objective: In this pilot study, we visualised the primary distribution of injected botulinumtoxin (BoNT)-bolus in upper limb spasticity (ULS) and, for control (HC), NaCl bolus of different volumes by magnetic resonance tomography (MRI). Material and Methods: Sagittal, dynamic BFFE sequences were performed during injection of 1 ml BoNT/NaCl bolus in spastic (n = 4), 1 ml NaCl in right, and 2 ml NaCl in left M. biceps brachii in HC (n = 6). Results: Immediate increase of hyperintensity occurred parallel to muscle fibres. The primary distribution length (mean: HC: 1 ml: 5,3 cm; 2 ml 5,7 cm; ULS: 3,3 cm) was…
