Which diagnostic studies are commonly used to evaluate fetal death?

• A. EEG
• B. Ultrasound, fetal monitoring, and amniocentesis
• C. Chest X-ray
• D. Colonoscopy

Answer: (B)

When fetal death is suspected, a combination of imaging, fetal status assessment, and fluid analysis is used to confirm death and explore possible causes. Ultrasound is the key initial tool because it can definitively show absence of fetal cardiac activity and movement, and it also assesses the placenta and uterus for any complicating factors. Fetal monitoring, typically with electronic fetal heart rate monitoring, helps document the absence of a fetal heartbeat over time and confirms nonviability. Amniocentesis provides amniotic fluid for analysis, including fetal karyotype and infectious studies, which helps identify chromosomal abnormalities or infections that might explain the fetal loss. Together, these studies are commonly used to evaluate fetal death. Other tests like EEG, chest X-ray, or colonoscopy aren’t relevant to assessing intrauterine fetal viability or its causes.
