The aim of this study was to assess the small bowel transit time in patients with Parkinson's disease (PD). Ten patients with PD with no gastrointestinal complaints and ten healthy control subjects were investigated using single photon emission computed tomography fused with computed tomography after swallowing of a specially prepared capsule containing technetium 99m, which allowed visualization of the passage in the intestines. Preliminary results show that the small intestine passage in PD patients was prolonged compared to controls.
