Multimodality imaging in primary hyperparathyroidism

Area of Science:

• Endocrinology
• Radiology
• Nuclear Medicine

Background:

• Parathyroid adenoma localization varies institutionally due to differing imaging availability and expertise.
• There is no established consensus on the optimal imaging strategy for primary hyperparathyroidism.

Purpose of the Study:

• To review and evaluate the efficacy of diverse imaging modalities for parathyroid adenoma localization.
• To highlight the advantages and limitations of each technique in various clinical scenarios.
• To propose a systematic imaging approach for improved diagnostic accuracy.

Main Methods:

• Clinico-radiological review of literature and case examples.
• Evaluation of high-resolution ultrasound, 99mTc-sestamibi scintigraphy (planar and SPECT/CT), 4D CT, MRI, PET/CT, and selective venous sampling.
• Discussion of parathyroid anatomy and embryology.

Main Results:

• Each imaging technique possesses unique strengths and weaknesses for parathyroid localization.
• Integrated SPECT/CT and 4D CT offer advanced visualization capabilities.
• Anatomical knowledge is critical for surgical planning.

Conclusions:

• A systematic, multi-modality imaging approach can maximize the accuracy of parathyroid lesion localization.
• Accurate localization is essential for optimizing surgical outcomes in primary hyperparathyroidism.
