A Practical Approach to the Fetal CNS - Part 1
What is our Approach
What is our Approach
In the following lecture series on CNS imaging of the fetus, we will outline why we feel that a limited sequence of views that is relatively easy to obtain can help you to exclude almost any significant CNS anomaly
Take Home Points
incidence of CNS Anomalies
- The individual anomalies mentioned her all have an incidence of < 1/1000 pregnancies
- This begs the question, how much work should we invest in finding these rare entities?
what are the possible approaches for diagnosis
- The "Positive" Approach
- Scan, scan, scan: Do a detailed scan scrutinizing the entire brain for any anomalies
- The "Negative" Approach
- Find a reasonable "sequence of views" that effectively excludes any significant anomaly
- This is our approach and the approach we will discuss in the remaining lectures
