A new first-trimester ultrasound lexicon standardizes terminology for intrauterine pregnancy (IUP), ectopic pregnancy (EP), and early pregnancy loss (EPL). This consensus-based guide aims to improve communication among healthcare providers and patients.
Area of Science:
- Obstetrics and Gynecology
- Radiology
- Medical Terminology
Background:
- Current first-trimester ultrasound terminology lacks standardization, potentially leading to miscommunication.
- Existing terms for early pregnancy complications are varied and can be imprecise.
Purpose of the Study:
- To establish a standardized, evidence-based lexicon for first-trimester ultrasound imaging.
- To provide clear definitions and preferred terms for intrauterine pregnancy, ectopic pregnancy, and early pregnancy loss.
Main Methods:
- A multisociety panel convened to develop the lexicon.
- A modified Delphi process was employed, requiring at least 80% consensus for term agreement.
- Scientific evidence, societal guidelines, and expert consensus informed the process.
Main Results:
- Agreement was reached on preferred terms, synonyms, and terms to avoid for first-trimester ultrasound findings.
- Specific definitions were established for intrauterine pregnancy (IUP) and ectopic pregnancy (EP), including cesarean scar implantation.
- Recommended terms include 'cardiac activity' over 'heartbeat' and 'early pregnancy loss' (EPL) to replace 'pregnancy failure.'
Conclusions:
- The developed lexicon provides a standardized framework for first-trimester ultrasound reporting.
- This standardized terminology aims to enhance clarity and consistency in communication among imagers, clinicians, and patients.
- The lexicon addresses critical areas such as pregnancy location and early pregnancy outcomes.

Ultrasound I: Abdominal Ultrasonography
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
