Three-dimensional sonography in the evaluation of primary hyperparathyroidism

Area of Science:

• Radiology
• Endocrinology
• Medical Imaging

Background:

• Primary hyperparathyroidism is a condition requiring accurate preoperative localization of parathyroid glands.
• Conventional two-dimensional sonography is a standard imaging modality for parathyroid evaluation.

Purpose of the Study:

• To review the diagnostic utility of three-dimensional sonography in primary hyperparathyroidism.
• To illustrate the imaging characteristics of parathyroid glands using grayscale and Doppler sonography.
• To highlight the added value of three-dimensional scanning in preoperative assessment.

Main Methods:

• This pictorial essay reviews grayscale and Doppler findings on two-dimensional sonography.
• Characteristic appearances of parathyroid glands are presented.
• The application and benefits of three-dimensional sonography are demonstrated.

Main Results:

• Two-dimensional sonography reveals characteristic grayscale and Doppler features of parathyroid glands.
• Three-dimensional sonography provides additional benefits in visualizing parathyroid gland anatomy and spatial relationships.

Conclusions:

• Three-dimensional sonography is a valuable tool for the preoperative evaluation of primary hyperparathyroidism.
• The technique offers enhanced visualization beyond conventional two-dimensional sonography.
