Trailers (81): Fetal imaging guidelines

Reddy et al. Fetal imaging

Why should you read about this topic?

Fetal imaging is ubiquitous and practice patterns vary widely, perhaps too much so.  We need balanced, evidence-based guidelines for its use.

What were the authors trying to do?

Define indications for ultrasound and MRI in pregnancy, when and how often studies should be performed, methods to optimize cost effectiveness, and identify opportunities for research

Who participated and in what setting?

Representatives of the NICHD, SMFM, AIUM, ACOG, ACR, Society for Pediatric Radiology, and Society of Radiologists in Ultrasound held a fetal imaging workshop

What was the study design?

Consensus development

What were the main outcome measures?

Evidence for indications, timing, and clinical usefulness of fetal ultrasonography and magnetic resonance imaging

What were the results?

Optimal timing for a single obstetric ultrasound is at 18-20 weeks.  Additional sonograms have specific indications.

What is the most interesting image in the paper?

Table 2

What were the study strengths and weaknesses?

Strengths:  attempt to standardize fetal imaging.  Weaknesses: consensus compromise.

What does the study contribute for your practice?

Guidelines for comparisons with and adjustments of your protocols.
