    Summary
    This summary is machine-generated.

    Gray-scale ultrasound can identify enlarged parathyroid glands in primary hyperparathyroidism patients. While sensitivity was limited, its low false-positive rate makes it a useful diagnostic tool.

    Area of Science:

    • Radiology
    • Endocrinology
    • Surgical Oncology

    Background:

    • Primary hyperparathyroidism is often diagnosed by elevated calcium levels.
    • Accurate localization of abnormal parathyroid glands is crucial for surgical planning.
    • Noninvasive imaging modalities play a key role in preoperative assessment.

    Purpose of the Study:

    • To evaluate the efficacy of gray-scale ultrasound in identifying parathyroid glands in patients with primary hyperparathyroidism.
    • To assess the diagnostic performance, including sensitivity and specificity, of ultrasound for parathyroid adenomas.
    • To describe anatomical limitations and potential pitfalls associated with ultrasound examination of the parathyroid glands.

    Main Methods:

    • Gray-scale ultrasound imaging was performed on patients diagnosed with primary hyperparathyroidism.

  • A total of 25 pathologically and anatomically confirmed enlarged parathyroid glands were assessed.
  • Ultrasound findings were correlated with pathological and anatomical data.

    • Main Results:

    • Twenty-one out of 25 enlarged parathyroid glands (greater than 5 mm) were successfully identified by ultrasound.
    • The size of identified glands ranged from 6 to 15 mm.
    • The study demonstrated a poor nosological sensitivity but a low false-positive rate for ultrasound.

    Conclusions:

    • Gray-scale ultrasound is a valuable tool for detecting enlarged parathyroid glands in primary hyperparathyroidism, despite limitations in sensitivity.
    • The low false-positive rate of ultrasound is advantageous in clinical practice.
    • Understanding anatomical limitations is essential for optimizing ultrasound's role in diagnosing and managing primary hyperparathyroidism.
