“…Our results for the control group were in agreement with the results of Li et al (11). Our results are also compatible with a recent study on postpartum placentas, which reported higher elasticity values in the central region of the placenta of intrauterine growth-restricted fetuses and hypertensive pregnancies (12). Their elasticity values cannot be compared to ours due to their ex vivo study design.…”

“…Despite that the authors did not observe any histological damage to the placental tissue after ARFI examination and some researches confirm that temperature increase caused by pulse burst might still be within the safe limits determined by Food and Drug Administration [26][27][28], safety of ARFI or other similar techniques on pregnant should be carefully investigated.…”

“…Results revealed a significant difference in shear wave velocity between FGR and normal group -higher in FGR group (1.94 ± 0.74 vs. ± 1.31 0.35, p < 0.05), and no significant difference between normal and PIH group. Moreover, authors noticed a correlation between increased velocity and decreased birth weight Z-score [26].…”

Sonoelastography is a novel technique that uses ultrasound waves to assess the elasticity of tissues noninvasively. It provides an ultrasound-based method to detect and display the relative stiffness of tissue. The main principle of sonoelastography is the measurement of tissue distortion in response to external compression. Changes in elasticity and tissues deformation elicited by compression are measured, processed and then shown in real time presentation with color-coded elastograms. Most of the elastography applications are well known and have been described in detail in adults, e.g. evaluation of liver fibrosis or thyroid nodules. Similarly, most of sonoelastographic studies are based on groups of adults. The purpose of this review article is to bring this technology closer to pediatric clinicians and to summarize some of its current clinical applications that are being pursued. In this part we take into consideration utility of elastography in evaluation pathologies of musculoskeletal system, lymphatic nodes, thyroid, kidneys in pediatric patients and also elastography of placenta (Adv Clin Exp Med 2015, 24, 4, 725-730).

“…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.…”

“…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. Placental evaluation with ARFI elastosonography has been studied in hypertensive disorders and fetal growth restricted pregnancies and a stiffer placenta in both groups was reported [13]. To date, no study has been found which has evaluated the placental tissue stiffness in maternal red blood cell alloimmunization.…”

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.
