“…One of the most frequent severe spinal abnormalities, open spina bifida, is usually associated with abnormal intracranial anatomy: up to 97% of cases present with the so‐called ‘banana sign’, which is due to Chiari‐II malformation 25 . However, a longitudinal section of the fetal spine should be sought 4 if technically feasible, because it may reveal, at least in some cases, other spinal malformations, including vertebral abnormalities and sacral agenesis, although the latter diagnosis may be challenging even for experts, due to the physiological non‐ossification of the caudal spine in the mid trimester 26 . Under normal conditions, a sagittal section of the spine at 18–24 gestational weeks demonstrates the three ossification centers of the vertebrae (one inside the body and one on each side at the junction between the lamina and pedicle) that surround the neural canal, and that appear as either two or three parallel lines, depending on the orientation of the ultrasound beam (Figure 3).…”

ISUOG Practice Guidelines (updated): sonographic examination of the fetal central nervous system. Part 1: performance of screening examination and indications for targeted neurosonography Clinical Standards Committee The 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 any 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.

“…We assumed that the negative results in that study were derived from the small age range. Other studies on foetal MRI have shown that sacral length, height, and sagittal and transverse diameters increase linearly with advancing gestational age [ 18 , 19 ]. Nevertheless, even in our study, for infants younger than one year, although the correlation coefficients were all >0.7, the R-squared values of simple regressions were less than 0.7 ( Fig.…”

“…Over the past several years, magnetic resonance imaging (MRI) has been used increasingly as an adjunct examination to US for the evaluation of fetal anomalies (9,10) and has proven useful in imaging fetal spinal canals and cord pathologies (11) with ultrafast spinecho T2-weighted imaging sequences (12)(13)(14)(15)(16)(17). However, literature regarding the use of MRI for the diagnosis of the musculoskeletal system (18)(19)(20)(21) and, in particular, bony spinal structures, is scarce and mainly focuses on postmortem imaging examinations without vertebral developmental abnormalities (22)(23)(24)(25)(26) or case reports (27,28). Recently, with the improvement and modification of fetal imaging of the susceptibility-weighted imaging (SWI) sequence, the application of fetal MRI for bony spinal structures has attracted mounting attention (29,30).…”

Background: Magnetic resonance imaging (MRI) has been used increasingly as an adjunct examination to ultrasound (US) for the evaluation of fetal anomalies. The purpose of this study was to determine whether the accuracy and confidence of diagnosing fetal vertebral anomalies are improved with MRI. We also assessed whether fetal MRI provides additional information when diagnosing fetal vertebral anomalies. Methods:We performed a single-center, retrospective study of 127 pregnant women with fetuses suspected of having vertebral anomalies on US examination; women also underwent fetal MRI scanning. Comparisons of diagnostic accuracy and confidence were made between MRI and US for the identification of fetal vertebral anomalies. We also assessed any additional information provided by MRI. McNemar's paired binomial test, chi-square test, or Fisher's exact test were used to compare the diagnostic ability between MRI and US. In all cases, postnatal or postmortem imaging findings were used as reference standards.Results: A total of 127 participants were recruited between December 2015 and January 2021. Fetal vertebral anomalies were detected in 63.8% (81/127) cases and found to be negative in 36.2% (46/127) of cases at follow up. The diagnostic accuracy of vertebral anomalies was 46.9% (38/81) for US and 84.0%
