“…The total lung volume was estimated by subtracting the fetal heart volume from the fetal thorax volume. This approach had the disadvantage of including parts of the mediastinal vessels and parts of the thymus in the calculated pulmonary volume [13,14]. In cases of CDH, the herniated organs make this technique unfeasible.…”

We report on 2 fetuses with congenital diaphragmatic hernia (CDH) in whom the fetal lung volumes were estimated by three-dimensional ultrasound and the results compared with the postmortem lung volume measurements. Both examiners (sonographer and pathologist) were blinded to each other’s results. The 1st case was a right CDH diagnosed at 20 weeks of gestation. The 2nd case was a left CDH diagnosed at 22 weeks of gestation. Both pregnancies were terminated upon request of the parents. Three-dimensional ultrasound estimation of the fetal lung volume was performed 1 day before termination of pregnancy using the technique of rotation of the three perpendicular planes. The left and right lung volumes estimated by three-dimensional ultrasound were 3.88 and 1.87 cm³, respectively, in the 1st case and 0 and 5.52 cm³, respectively, in the 2nd case. On postmortem examination, the left and right lung volumes were 3.0 and 2.2 cm³, respectively, in case 1 and 1.1 and 5.6 cm³, respectively, in case 2. This suggests that a three-dimensional estimation of pulmonary volumes may be correlated with postmortem findings in cases with CDH.

“…Again, for either volumetric method, the actually measured volume should be expressed as a function of what is expected for an appropriate normal match still using the same measuring method. Several groups have published nomograms for multiplanar or rotational volume 3D US acquisitions in normal pregnancies [7][8][9][10][11][12][13][14][15] .…”

“…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.…”

MRI investigation of normal fetal lung maturation using signal intensities on different imaging sequences

et al. 2006

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.
