Which test confirms cephalopelvic disproportion?

The correct choice for confirming cephalopelvic disproportion is the ultrasound. This imaging technique is especially useful in obstetrics as it provides valuable information regarding the size and position of the fetus and the dimensions of the pelvis. During pregnancy, an ultrasound can help assess whether the fetal head is likely to fit through the birth canal, considering factors like fetal size, head circumference, and pelvic measurements.

Ultrasound is considered non-invasive, widely available, and effective in providing real-time visualization, which is crucial in assessing morphological relationships in the pelvis and fetal structure. This helps healthcare providers plan for delivery by determining whether a vaginal birth is feasible or if a cesarean section may be necessary due to cephalopelvic disproportion.

While other imaging tests like digital pelvimetry, X-rays, and CT scans could provide information about pelvic size, they are not the primary or most effective methods to assess cephalopelvic disproportion in clinical practice. Digital pelvimetry is a manual method and less reliable than ultrasound, X-rays are typically avoided during pregnancy due to radiation exposure, and CT scans are not commonly used in obstetric assessments for the same reason. Thus, ultrasound stands out as the most appropriate and reliable method to confirm cephalopel
