Shear Wave Elastography in Gestational Diabetes Mellitus

SWE is a novel noninvasive dynamic ultrasound technique which refers to measurement for quantitative analysis of tissue elasticity. The stiffer the tissue, the higher shear wave velocity is measured. Elastographic examinations were performed by physicians using Samsung HS70A ultrasound system with a Samsung CA1-7A convex transducer and S-Shear wave technique. During the examination, patients were lying in supine position, breathing levels kept steady to prevent noise and artifacts and minimum pressure were applied on the transducer to eliminate misleading tissue compression. A region of interest (ROI) box of 10 × 10 mm was positioned on placenta and six measurements were obtained from central and peripheral zones of placenta while avoiding vascular structures
