Thoracic Anatomy
This structure separates the thoracic cavity from the abdominal cavity.
What is the diaphragm?
Fetal breathing movements can be observed using this modality.
What is ultrasound?
This rare condition results in fluid accumulation within the pleural cavity.
What is pleural effusion?
This imaging modality is the primary tool for fetal thoracic evaluation.
What is ultrasound?
Pulmonary hypoplasia may occur secondary to this abnormal fluid condition.
What is oligohydramnios?
These paired organs are responsible for gas exchange after birth.
What are the lungs?
The four stages of lung development include this final stage.
What is the alveolar stage?
This congenital anomaly involves herniation of abdominal organs into the chest cavity.
What is congenital diaphragmatic hernia (CDH)?
The fetal position and heart location are evaluated using this ultrasound plane.
What is the four-chamber view?
A favorable outcome is more likely in CPAM cases with this cyst type.
What is macrocystic?
This centrally located organ in the thorax shifts position in some fetal anomalies.
What is the heart?
Lung development begins at this gestational age.
What is around 5 weeks?
This thoracic mass contains cystic and solid components and can be macrocystic or microcystic.
What is congenital pulmonary airway malformation (CPAM)?
Color Doppler is used to assess this in thoracic lesions.
What is vascular supply?
In cases of large lesions, this prenatal intervention might be considered.
What is fetal surgery or thoracoamniotic shunting?
The normal position of the heart is referred to using this term.
What is levocardia?
This fluid-filled organ plays a role in fetal lung development by providing amniotic fluid.
What is the kidney?
A fetal lung lesion with systemic arterial supply is known as this.
What is bronchopulmonary sequestration?
This ratio helps determine the severity of a congenital diaphragmatic hernia.
What is the observed-to-expected LHR (O/E LHR)?
This condition must be ruled out when a cystic thoracic mass is seen.
What is congenital diaphragmatic hernia?
The fetal lungs appear with this echogenicity on ultrasound.
What is homogeneous and hyperechoic compared to the liver?
This key measurement helps assess the thoracic cavity and predict pulmonary hypoplasia.
What is the lung-to-head ratio (LHR)?
The presence of a hyperechoic mass in the chest with an anomalous feeding vessel is most likely this.
What is a pulmonary sequestration?
MRI may be used in fetal assessment for better visualization of this.
What is the lung volume or lesion extent?
This imaging finding suggests a poor prognosis in thoracic anomalies.
What is mediastinal shift or hydrops fetalis?
