“…There have been limited studies concerning ARFI investigating placental elasticity [17][18][19]. Sugitani et al [13] measured the placental elasticity by using ARFI in an ex vivo study and they found higher ARFI scores in intrauterine growth restricted and hypertensive pregnancies.…”

“…Sugitani et al [13] measured the placental elasticity by using ARFI in an ex vivo study and they found higher ARFI scores in intrauterine growth restricted and hypertensive pregnancies. Recent in vivo studies demonstrated that the placenta becomes stiffer in preeclamptic pregnancies [17][18][19]. Placental infarction, inflammation of trophoblastic villi and vasculitis are major findings which occur in intrauterine growth restricted and hypertensive pregnancies [25].…”

“…It has been used for various diseases as well as in placenta pathology [13][14][15][16][17][18][19]. Acoustic radiation force impulse (ARFI) elastography is relatively a new method which uses a short acoustic push pulse in the target tissue, which causes a tissue displacement of approximately 1-20 um.…”

Aims: Maternal red blood cell alloimmunization is an important cause of fetal morbidity and mortality in the perinatal period, despite well-organized prophylaxis programs. The objective of the study was to evaluate placental elasticity by using Acoustic Radiation Force Impulse (ARFI) in Rhesus (Rh) alloimmunized pregnant women with hydropic and nonhydropic fetuses and to compare those with healthy pregnant women. Material and methods: This case-control and descriptive study comprised twenty-eight healthy pregnant women, 14 Rh alloimmunized pregnant women with nonhydropic fetuses, and 16 Rh alloimmunized pregnant women with hydropic fetuses in the third trimester of pregnancy. Placental elasticity measurements were performed by ARFI elastosonography at the day of delivery. The maternal characteristics and neonatal outcomes of the patients were also noted. Results: The highest mean placental ARFI scores were observed in Rh alloimmunized pregnant women with hydropic fetuses (1.13 m/s) (p=0.001). Healthy controls and Rh alloimmunized pregnant women with nonhydropic fetuses had similar mean placenta ARFI scores (0.84 m/s, 0.88 m/s, respectively) (p<0.05). Conclusions: Based on the present findings, the placenta becomes stiffer in Rh alloimmunized pregnancies complicated with hydrops fetalis. The increased placental ARFI scores may be a supplemental marker for adverse pregnancy outcomes, additional to Doppler evaluation of middle cerebral artery. This data should be confirmed with a large sample size and prospective studies by using serial measurements of ARFI elastosonography in maternal red blood cell alloimmunization.

“…In obstetrics and gynaecology, elastography has been used to assess uterine fibroids, subchorionic hematoma, and cervical length in the cases of preterm labour [16–18]. It has also more recently been used to evaluate differences in placental function between normal and preeclamptic pregnancies and may be useful as an aid in predicting preeclampsia [19, 20]. …”

Morbidly adherent placentation (MAP) is a condition in which the placenta is abnormally attached to the uterine myometrium. MAP is a complication of pregnancy that can cause significant morbidity to the mother and fetus and therefore early diagnosis is crucial in its management and prevention of adverse outcomes. Ultrasonography remains the primary diagnostic tool for MAP, with magnetic resonance imaging (MRI) serving as a secondary diagnostic modality. Elastography is a relatively new concept in ultrasound based imaging, which has found application in several fields of medicine, including obstetrics, primarily for evaluation of the firmness of cervical tissue in a preterm labour setting. We report a case on a patient who was diagnosed with placenta increta on ultrasound, aided by elastography and her subsequent management with an en bloc hysterectomy.

Strain elastography in placental dysfunction: placental elasticity differences in normal and preeclamptic pregnancies in the second trimester

Abstract: The placental elasticity ratios measured by SE imaging during the second trimester differ between the normal pregnancies and the pregnancies complicated by PE. SE might be used as a supplement tool in addition to the existing methods for the prediction of PE.
