Official title

Parathyroid Adenoma Detection With Rubidium Chloride Imaging: A Proof-of-Concept Study

Overview

Assess the uptake of rubidium-82 in parathyroid adenomas.

Detailed description

Parathyroid adenomas demonstrate uptake of rubidium-82 chloride and can be detected with PET imaging.

The investigators aim to describe the uptake pattern of rubidium-82 chloride in parathyroid adenomas as well as compare the uptake pattern of rubidium-82 chloride to that of 18F-fluorocholine in patients with parathyroid adenoma.

Interventions

  • Other PET/CT imaging with rubidium-82
    PET imaging of the neck will be started immediately before infusion of 10 Megabecquerels per kilograms of rubidum-82 over 30 seconds. The acquisition will last 10 minutes. This will be followed by a non-contrast low-dose CT of the neck for localization and attenuation correction.

Primary outcome measures

  • Uptake pattern of rubidium-82 in parathyroid adenomas [Time frame: 3 months]
Secondary outcome measures (1)
  • Comparison between the uptakes of rubidium-82 and 18F-fluorocholine in patients with parathyroid adenomas [Time frame: 3 months]

Eligibility criteria

Inclusion criteria

  • Age ≥ 18y
  • Ability to undergo imaging logistics
  • Ability to provide informed consent
  • Biochemical evidence of primary hyperparathyroidism
  • Documented parathyroid adenoma on prior 18F-fluorocholine imaging

Exclusion criteria

  • Normocalcemic primary hyperparathyroidism
  • Breastfeeding or pregnancy
  • Claustrophobia or inability to undergo imaging logistics
  • Any other history, condition, therapy, or uncontrolled intercurrent illness, which could in the opinion of the investigator affect compliance with study requirements or which would make the participant unsuitable for this study
