In some cases the doctor may suspect the presence of conjoined twins
early in the pregnancy by finding that the mother’s uterus is larger than
expected and hearing two fetal heartbeats when listening through a
stethoscope. Conjoined twins can be diagnosed by ultrasound as early
as the eighth week of pregnancy. Magnetic resonance imaging (MRI) can
be used to identify which organ systems are shared between the twins.
Computed tomography (CT) scans are primarily useful in evaluating the
bony structures of twins fused at the hips or pelvis.
Electrocardiograms (ECGs) and electroencephalograms (EEGs)
may be used to evaluate the extent of shared heart or brain function
and to determine whether surgical separation of the twins is
possible.
