Ultrasound elastography in diagnosis and follow-up for patients with sialolithiasis.

Objectives:: This study aims to answer whether acoustic radiation force impulse imaging (ARFI) can reasonably be employed in initial examination and follow-up during therapy in patients with sialolithiasis, one of the most common non-malignant disorders of the salivary glands.

Methods:: Mechanical tissue properties of affected and contralateral healthy salivary glands were analyzed by ARFI in 129 patients with sialolithiasis. In different subgroup analyses, ARFI shear wave velocity values were compared between healthy and diseased submandibular or parotid glands, salivary glands with calculi exhibiting different sizes, as well as before and after therapy.

Ultrasound elastography in diagnosis and follow-up for patients with chronic recurrent parotitis.

Purpose: Chronic recurrent parotitis (CRP) is a non-obstructive disease with episodes characterized by painful swelling of the parotid gland. It presents in both a juvenile and an adult form, with no clear information on its actual origin. Diagnosis is based on patient medical history and ultrasound examination but is frequently not correctly identified.
