Brief Summary:
Prospective observational study to compare sensitivity of 3T functional Magnetic Resonance Imaging (3T fMRI) at diagnosing Parkinson's Disease (PD) against the benchmark DaTScan diagnostic test and clinical diagnosis at follow up.

Condition or disease Intervention/treatment

Intervention Details:
  • Other: Patient assessment
    Clinical examination, Examination, Questionnaires
  • Radiation: DATScan
    In small subgroup
  • Radiation: Orbital X-Ray
    If foreign body in eye needs exclusion
  • Other: Magnetic Resonance Imaging (MRI)
    MRI scanning of all subjects

Primary Outcome Measures :
  1. Presence or absence of "swallow tail" on nigrosome MRI at 3T [ Time Frame: 12 months ]
    Does absence of "swallow tail" on nigrosome MRI at 3T correlate with final diagnosis of Parkinson's Disease 12 months after initial presentation of clinically uncertain diagnosis? Is this correlation as accurate as that of DatScan? Is nigrosome MRI at 3T at least 80% sensitive and 80% specific to predict the final clinical diagnosis of Parkinson's disease vs. other movement disorders in patients with indeterminate or atypical parkinsonian features? Is the "swallow tail" and accurate marker of early Parkinson's disease.

Ages Eligible for Study:   21 Years to 90 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
All potential participants need to have to capacity to give consent prior to study enrolment. Study participation is not possible if the participant is unable to give consent or does not have the capacity to consent.

Inclusion criteria:

  • Ability to give informed consent
  • Age > 21 to < 90 years
  • Clinical symptoms suspicious for a diagnosis of Parkinson's disease but clinical uncertainty with regards to a definite diagnosis:

    • Clinical symptoms not meeting all of the required UK brain bank diagnostic criteria for the diagnosis of PD
    • Clinical features not typically associated with PD and therefore raising the possibility of a different type disorder/movement disorder
  • Referred for a DatScan as part of the NHS clinical diagnostic workup to investigate a suspicion for a parkinsonian movement disorder type disease or referred for a research DatScan as part of this study for the diagnostic workup to investigate a suspicion for a parkinsonian movement disorder type disease.

Exclusion criteria:

  • Participants with any known contraindication to MRI such as:

    • Intracranial aneurysm clips
    • Cardiac pacemakers and defibrillators
    • Cochlear implants.
    • MR-incompatible metal implant or tattoo
    • Patients with a significant head tremor
    • Claustrophobia
    • Pregnant women
    • Participants that are felt to be unfit for the MRI scan according to the judgement of medically qualified personnel, either on the research team, or the patient's clinical team. (eg. due to back pain, claustrophobia, acute sickness etc.) This includes patients with signs of impaired temperature regulation such as an extremely high fever.
  • (only for those planned for research DatScan) Participants in which a DatScan nuclear medical study can't be performed due to

    • Severe allergy to iodide compounds
    • Thyroid gland dysfunction
