“…SWS overcomes the limitations of strain elastography by automatically generating an acoustic force that creates a mechanical impulse, leading to tissue displacement in the form of shear‐waves. This technology has been widely used in the assessment of breast or prostate mass and liver cirrhosis 17‐19 . The advantage of SWS is that the generation of the mechanical impulse is operator‐independent 20 …”

“…This technology has been widely used in the assessment of breast or prostate mass and liver cirrhosis. [17][18][19] The advantage of SWS is that the generation of the mechanical impulse is operator-independent. 20 The cervical canal is surrounded by a layer of longitudinal smooth muscle fibers that are wrapped circumferentially by a layer of smooth muscle and collagenous cells, which may act as a "sphincter" to maintain the pregnancy.…”

Preterm birth (PTB) is defined as a birth that occurs before 37 weeks of gestation, which is the leading cause of perinatal morbidity and mortality. 1 The inherent cervical length and strength are two main features of the cervix that determine whether a pregnant woman is at risk for spontaneous PTB. 2 A short cervix identified by transvaginal ultrasound in the second trimester of pregnancy is associated with a significant risk of spontaneous PTB. It is recognized that the measurement of cervical length in the second trimester can identify high-risk women that may benefit from progesterone prophylaxis. 3,4 However, the low sensitivity and positive predictive value have limited the clinical utility of cervical length assessment as a universal screening tool. 5-7 In the first trimester of pregnancy, the presence of the undeveloped lower uterine segment and the variable degree of the curvature of the endocervical canal have generated significant technical challenges for the cervical length to be measured, which

“…The technology of elasticity imaging has been applied in clinical practice over the past decade. Clinical benefits of elastography have been shown in imaging of the breast [12] , thyroid [13] and liver [14] with accumulating evidence of improved interpretation specially for classifying breast lesions [12] . It is hypothesized that if the value demonstrated with this modality is extrapolated to assessment of various tissue invasiveness, it may be implicated in evaluating women with suspected abnormal placental invasion.…”

Background: Placenta accreta spectrum is a term which describes abnormal invasion of the placenta into the uterine myometrium. The first line in diagnosis is ultrasonography and magnetic resonance imaging may complement the diagnosis. Aim: The aim of the work is to assess the accuracy of shear wave elastography in predication of placental invasion in women with placental previa. Materials and Methods: This is a prospective cohort study which was conducted in Ain Shams University on 50 women with a diagnosis of anterior placenta previa and history of previous cesarean section who were pregnant at 32 weeks or more and were planned for delivery by elective cesarean section. They were subjected to ultrasonography and elastography study and the diagnosis of placenta accreta spectrum was confirmed/ excluded intraoperatively. Results: Placental separation was normal in 36% of cases, delayed in 46 % of cases, partial in 6% of cases only whereas non separation occurred in 12% of cases. elastrgraphy had a sensitivity of 73.7%, specificity of 90.3%, positive predicting value of 82.4% and negative predictive value of 84.8% in diagnosing cases with abnormal placental invasion while sensitivity, specificity positive and negative predictive value of ultrasonography in diagnosing abnormal placental invasion was 89.5%, 96.8%, 94.4% and 93.8% respectively. Conclusion:Elastography is sensitive and specific but inferior to ultrasonography in evaluating women with suspected placenta accreta spectrum but it may be useful in diagnosis of focal invasion.

“…In recent years, many clinical studies of ultrasound elastography have focused on the prognostication and treatment response evaluation in different soft tissue tumors (204). In some studies, a correlation between breast tumor stiffness and receptor status, histological grade, and Ki-67 expression has been reported, suggesting that tumor evaluation using elastography could in future venture beyond determining whether tumors are malignant or benign (205).…”

This review looks at highlights of the development in ultrasound, ranging from interventional ultrasound and Doppler to the newest techniques like contrast-enhanced ultrasound and elastography, and gives reference to some of the valuable articles in Acta Radiologica. Ultrasound equipment is now available in any size and for any purpose, ranging from handheld devices to high-end devices, and the scientific societies include ultrasound professionals of all disciplines publishing guidelines and recommendations. Interventional ultrasound is expanding the field of use of ultrasound-guided interventions into nearly all specialties of medicine, from ultrasound guidance in minimally invasive robotic procedures to simple ultrasound-guided punctures performed by general practitioners. Each medical specialty is urged to define minimum requirements for equipment, education, training, and maintenance of skills, also for medical students. The clinical application of contrast-enhanced ultrasound and elastography is a topic often seen in current research settings.
