Purpose
“The only localization study needed in a patient with hyperparathyroidism is to localize an experienced parathyroid surgeon” is an old saying by Doppman.(1) However,
in the era of minimally invasive surgeries which have far less morbidity and equal success rate,
accurate pre-operative localization of the parathyroid lesion has become extremely important.(2,3)
Ultrasound and Tc99m Sestamibi scinitigraphy are the imaging modalities of choice for pre-operative localization of the parathyroid lesion.
(1,2,4) But these modalities are fraught with significant false positive and false negative rates upto 30%.
Concomitant thyroid nodules and inability to differentiate thyroid and parathyroid nodules are the most common reasons for the same.
(3,5–10)
There is only one previous study on the use of stain elastography in the evaluation of parathyroid lesions.
(11) However,
there has been no previous study looking at the usefulness of shear wave elastography in differentiating parathyroid and thyroid lesions.
For the first time,
we aimed to assess the usefulness of ARFI elastography in differentiating parathyroid and thyroid lesions.
