ISUOG Practice Guidelines (updated): performance of the routine mid‐trimester fetal ultrasound scan

Abstract

ISUOG Practice Guidelines (updated): performance of the routine mid-trimester fetal ultrasound scan Clinical Standards CommitteeThe International Society of Ultrasound in Obstetrics and Gynecology (ISUOG) is a scientific organization that encourages sound clinical practice, and high-quality teaching and research related to diagnostic imaging in women's healthcare. The ISUOG Clinical Standards Committee (CSC) has a remit to develop Practice Guidelines and Consensus Statements as educational recommendations that provide healthcare practitioners with a consensus-based approach, from experts, for diagnostic imaging. They are intended to reflect what is considered by ISUOG to be the best practice at the time at which they are issued. Although ISUOG has made every effort to ensure that Guidelines are accurate when issued, neither the Society nor any of its employees or members accepts liability for the consequences of any inaccurate or misleading data, opinions or statements issued by the CSC. The ISUOG CSC documents are not intended to establish a legal standard of care, because interpretation of the evidence that underpins the Guidelines may be influenced by individual circumstances, local protocol and available resources. Approved Guidelines can be distributed freely with the permission of ISUOG (

Current use and performance of the different fetal growth charts in the Italian population

“…Fetal measurements were made in accordance with the ISUOG guidelines [11] and as previously described [6]. The EFW (in grams) was computed using the Hadlock 3 formula [12]:…”

The birth weight of macrosomia influence the accuracy of ultrasound estimation of fetal weight at term

“…The BPD, AC, HC, and FL measurements were performed strictly following the practice guidelines 26 . Detailed measurement standards are shown in Figure 1 and Table 1.…”

ISUOG Practice Guidelines: role of ultrasound in the prediction of spontaneous preterm birth

“…Therefore, in accordance with the 2022 updated ISUOG Practice Guidelines on the performance of the routine mid-trimester fetal ultrasound scan 84 , when a comprehensive local feasibility analysis coupled with availability of preventive measures indicate that there are sufficient funding, skills and equipment, we recommend universal CL screening for PTB using TVS for asymptomatic singleton pregnancies between 18 and 24 weeks, and prescription of natural vaginal progesterone for patients identified as having CL ≤ 25 mm (Figure 11). The benefit/risk ratio favors a CL cut-off of ≤ 25 mm rather than ≤ 20 mm or ≤ 15 mm, since a missed opportunity to intervene carries a greater risk of poor outcome than does overtreating with natural vaginal progesterone, which carries only minimal, if any, risk.…”
