  • Assessment of the fetal lungs in utero - American Journal of Obstetrics . . .
    Ultrasound findings of primary lung hypoplasia can include reduced fetal chest circumference and fetal lung-to-head ratio, 5 and major mediastinal shift can also be observed when hypoplastic right lung is diagnosed Assessment of the position and size of the heart is therefore imperative
  • The Fetal Chest - Radiology Key
    Three-dimensional ultrasound in a surface or tomographic display can help in demonstrating various chest structures, especially in transvaginal scanning where transducer manipulation is limited Clear visualization of the lungs can be achieved from about the 12th week of gestation onward
  • Ultrasound Evaluation of the Fetal Thorax - Radiology Key
    CPAMs are the most common lung lesions identified by fetal ultrasound imaging On occasion, hybrid lesions are found, with imaging and pathologic features of both CPAM and BPS Historically, CPAMs were thought to be infrequent, with reported incidence between 1 in 25,000 and 1 in 35,000 live births
  • Echogenic fetal lung lesions | Radiology Reference Article . . .
    Echogenic fetal lung lesions on antenatal ultrasound can be detected in a number of situations They include: 1 Biyyam DR, Chapman T, Ferguson MR et-al Congenital lung abnormalities: embryologic features, prenatal diagnosis, and postnatal radiologic-pathologic correlation
  • ISUOG Practice Guidelines (updated): performance of 11–14‐week . . .
    Performing a routine first-trimester ultrasound examination at 11 + 0 to 14 + 0 weeks' gestation is of value for confirming viability and plurality, accurate pregnancy dating, screening for aneuploidies, identification of major structural anomalies and screening for preterm pre-eclampsia
  • Prenatal diagnosis and outcome of echogenic fetal lung lesions
    atresia’, ‘fetal surgery’, ‘prenatal diagnosis’, ‘ultrasound’ and ‘fetus’ RESULTS The fetal medicine database search identified 193 fetuses with an echogenic lung lesion diagnosed at 18–35 weeks of gestation, which included nine cases of CHAOS, 170 of CAM and 14 of PS Congenital high airway obstruction syndrome (CHAOS)
  • Assessment of lung area in normal fetuses at 12–32 weeks - Fetal Medicine
    Results The respective mean left and right lung areas (manual tracing) increased with gestational age, from 36 and 58 mm2 at 12 weeks to 220 and 325 mm2 at 20 weeks and 594 and 885 mm2 at 32 weeks This 16-fold increase in lung area was accompanied by a four-fold increase in head circumference
  • Prenatal diagnosis and outcome of echogenic fetal lung lesions
    In this study, we describe the prenatal sonographic features, antenatal management and outcome of 193 fetuses with echogenic lung lesions examined in our unit and review the literature on these conditions
  • Assessment of the fetal lungs in utero - PubMed
    Two-dimensional ultrasound is the mainstay of investigation of pulmonary pathology during pregnancy, providing good prognostication in conditions such as congenital diaphragmatic hernia; however, it is less validated in other high-risk groups such as those with congenital pulmonary airway malformation or preterm premature rupture of membranes
  • A pictorial guide for the second trimester ultrasound - PMC
    Introduction: The second trimester ultrasound remains an important screening tool for detecting fetal abnormalities This pictorial guide for the second trimester ultrasound is designed to assist practitioners to produce a high quality diagnostic survey of the fetus by demonstrating and describing recommended images
