Recommendations on routine mid-trimester anomaly scan.

Area of Science:

• Medical Imaging
• Obstetrics
• Prenatal Diagnosis

Background:

• Mid-trimester anomaly scans are crucial for detecting fetal abnormalities.
• Prenatal detection rates vary due to local factors like resources and expertise.
• Standardizing scan protocols is essential for equitable care.

Purpose of the Study:

• To determine the minimal requirements for routine mid-trimester anomaly scans in Asian countries.
• To address variations in local circumstances, medical practices, and resource availability.
• To optimize the detection of fetal anomalies through standardized protocols.

Main Methods:

• Review of existing guidelines and literature on mid-trimester anomaly scans.
• Analysis of factors influencing prenatal detection rates in Asian contexts.
• Discussion of essential fetal structures and optional views for routine scans.

Main Results:

• A consensus on the core components of a routine mid-trimester anomaly scan was developed.
• Identification of key factors (e.g., sonographer expertise, equipment) affecting scan efficacy.
• Distinction between mandatory and optional examination elements was proposed.

Conclusions:

• Establishing minimal requirements for anomaly scans is vital for improving prenatal care in Asia.
• A standardized approach, balancing comprehensiveness with feasibility, is necessary.
• Routine anomaly scans present ongoing clinical challenges requiring continuous evaluation and adaptation.
