The aim of the study is to investigate the applicability and performance of 64Cu-DOTATATE PET/CT/MR for diagnosis in patients with Lyme neuroborreliosis (LNB). In this prospective, observational cohort study with 64Cu-DOTATATE, the investigators wish to include a total of 50 patients clinically suspected of LNB. The investigators will investigate the diagnostic value of 64Cu-DOTATATE-PET comparing clinically suspected and CSF verified LNB patients with clinically suspected patients without CSF verification. The investigators hypothesize that the information obtained from 64Cu-DOTATATE PET/CT/MRI can improve the diagnostics of LNB as well as that 64Cu-DOTATATE PET/CT/MRI will be able to contribute to the follow-up of patients by adding prognostic information and the risk of persistent symptoms. The application of 64Cu-DOTATATE PET/CT/MRI in the diagnostic work-up of LNB would thus expectedly lead to a more precise diagnosis and risk assessment.
