Conclusion

CEUS of parathyroid lesions shows high sensitivity and specificity in differentiation of adenoma, regardless after injecting 1 ml vs 2 ml of contrast agent. Hypereplasia shows homogeneous enhancement, uptake and washout appears fastpaced in comparson to adenoma, whereas adenoma is characterized by peripheral uptake, central washout and slower hemodynamics.
