Detailed first trimester ultrasound scans can now identify subtle fetal malformations. Advances in high-frequency transvaginal transducers enable comprehensive early fetal anatomy analysis, improving detection rates for congenital anomalies.
Area of Science:
- Obstetrics and Gynecology
- Medical Imaging
- Fetal Medicine
Background:
- First trimester ultrasound screening, including nuchal translucency, is standard practice.
- Technological advancements have enhanced ultrasound capabilities for early fetal assessment.
Purpose of the Study:
- To demonstrate the feasibility of detailed early fetal anatomical analysis using advanced ultrasound.
- To highlight the identification of fetal malformations during the first trimester.
Main Methods:
- Review of prospective studies utilizing high-frequency transvaginal ultrasound transducers.
- Analysis of optimal gestational age windows for visualizing specific fetal anatomical structures.
Main Results:
- High-frequency transvaginal ultrasound allows for detailed examination of early fetal anatomy.
- Numerous fetal malformations, including subtle defects, can be identified in the first trimester.
- Specific gestational age timelines are provided for optimal anatomical structure assessment.
Conclusions:
- Advanced ultrasound technology significantly improves the detection of fetal malformations in the first trimester.
- Routine first trimester scans can be enhanced for comprehensive anatomical evaluation.
- Timely assessment based on gestational age is crucial for accurate diagnosis.

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...

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
