The aims are to describe the profile of these patients particularly neurobehavioral and cognitive symptoms, changes in calcium and PTH over time and treatment modalities.Methods: Patients newly diagnosed with PHPT and with high serum calcium leve...

Objective: Acoustic Radiation Force Impulse (ARFI)-Imaging is a novel ultrasound-based elastography method enabling quantitative measurement of tissue stiffness. The aim of the present study was to evaluate ARFI for the differentiation of thyroid nodules and to compare it with the well known qualitative Realtime-Elastography (RTE)Materials and Methods: ARFI-imaging involves the mechanical excitation of tissue using short-duration acoustic pulses to gener...
