“…Several publications indicate that fetal lung volume can be reliably assessed with both two-and three-dimensional (3D) ultrasound, and the data obtained can be used to predict pulmonary hypoplasia [2][3][4][5][6]. However, ultrasound data do not provide functional and biochemical information about the fetal lungs.…”

To purpose of this paper is to study the relation between normal lung maturation signal and changes in intensity ratios (SIR) and to determine which magnetic resonance imaging sequence provides the strongest correlation of normal lung SIs with gestational age. 126 normal singleton pregnancies (20-37 weeks) were examined with a 1.5 Tesla unit. Mean SIs for lungs, liver, and gastric fluid were assessed on six different sequences, and SIRs of lung/liver (LLSIR) and lung/gastric fluid (LGSIR) were correlated with gestational age for each sequence. To evaluate the feasibility of SIRs in the prediction of the state of the lung maturity, accuracy of the predicted SIRs (D*) was measured by calculating relative residuals (D*-D)/D for each sequence. LLSIRs showed significant changes in every sequence (p<0.05), while LGSIRs only on two sequences. Significant differences were shown for the mean of absolute residuals for both LLSIRs (p<0.001) and for LGSIRs (p=0.003). Relative residuals of LLSIRs were significantly smaller on T1-weighted sequence, whereas they were significantly higher for LGSIRs on FLAIR sequence. Fetal liver seems to be adequate reference for the investigation of lung maturation. T1-weighted sequence was the most accurate for the measurement of the lung SIs; thus, we propose to determine LLSIR on T1-weighted sequence when evaluating lung development.

“…As neonates with non-lethal PH require intensive respiratory therapy immediately after delivery, an accurate prenatal diagnosis is important [26]. In this study, we chose the separate measurement of the volume of the fetal lungs, the technique chosen by most authors [13,23,26,27]. Preliminary studies obtained fetal lung volume by subtracting heart volume from thoracic volume [11,12].…”

Although three-dimensional ultrasound (3DUS) was already being used in the early 1980's 1-3 and the first commercially available three-dimensional scanner was presented in 1989 in Paris at the International Radiology Congress 4 , it has only been in the recent decade that the technology has found its way into clinical applications. This rapid development is mainly due to the equally rapid development of computer processor technology, essential for three-dimensional ultrasound. Originally used as a tool for creating a surface mode showing the face of the fetus and gender abnormalities, its application has become much broader nowadays. The technique is now becoming ever more important in obstetrics and gynecology, but also in many other fields such as cardiology, surgical applications and urology. Three-dimensional ultrasound is an easy, quick and cheap imaging technique without any known adverse effects on the mother or developing fetus as has been stated by the American Institute of Ultrasound in Medicine (AIUM). In addition, it has been reported by numerous authors to be very accurate in assessing volumes 5-9 . Recently, it has been suggested that both two-and three-dimensional ultrasound, especially in the 1st and 2nd trimester, are of positive influence in initiating the bonding between mother and infant 10 .Although the technique of 3DUS is relatively recent, its clinical importance has already been established in prenatal diagnosis and is likely to continue to increase. This review will provide an overview of the current applications of 3DUS in prenatal diagnosis. The applications will be discussed by subject. The fetal heart is briefly mentioned, since clinical applications of 3DUS studies of the heart are sparse and the new four dimensional ultrasound technologies, such as STIC (spatial temporal correlated imaging) are beyond the subject of this review. GESTATIONAL SACThe gestational sac (GS) is regarded as a reflection of the early uteroplacental unit function and 3DUS volumetry is suggested to have some predictive value for adverse

Reproducibility of Fetal Lung Volume Measurements With 3‐Dimensional Ultrasonography

Abstract: Our findings suggest that 3-dimensional ultrasonographically derived measurements are reliable and reproducible up to 30 weeks if a standard measurement technique is used.
