Diagnosis of abdominal neuroblastoma by imaging techniques is demandin
g, and in most cases several complementary modalities are needed for c
orrect staging. Ultrasonography is performed first, followed by contra
st CT and/or MRI. Both skeletal and specific MIBG scintigraphy are ess
ential in most cases. This applies not only for the primary diagnosis
but also for monitoring the response to therapy and for picking up rec
urrent disease.
