Both programs allowed statistical differentiation between Parkinson's syndrome and essential tremor. Strict operator protocols are needed with QuantiSPECT to reduce inter- and intra-operator variation. The three-dimensional method (BRASS) gave greater concordance than the two-dimensional method (QuantiSPECT) with the visual assessment, but at a cost of increased operator time.

The transfer of a DaTSCAN database between camera types is feasible, but ideally all data would be acquired on a single camera type and phantom data used to normalize the database accordingly.

Inflammatory arthritis in the context of cystic fibrosis (CF) can represent a diagnostic and therapeutic challenge. Poor recognition and under‐treatment of musculoskeletal conditions increases symptom burden, affects quality of life, and may lead to changes to an individual's ability to carry out activities of daily living and to exercise. A careful assessment and multidisciplinary approach is essential when considering a diagnosis of CF‐associated arthritis (CFA), both in terms of identifying other treatable conditions, such as rheumatoid arthritis, and effectively addressing symptoms. In this collaboration between CF specialists and Rheumatologists, we consider joint symptoms in patients with CF, with a focus on CFA. We offer a differential diagnosis list and consider steps to assess and manage CF patients presenting with arthralgia including appropriate up‐to‐date rheumatological assessment.
