Ultrasound imaging offers a critical tool for detecting fetal myelomeningocele, a neural tube defect visible at 21 weeks of gestation as shown in the provided image. This article explores the significance of this diagnostic image, providing a detailed look at the condition and its implications for prenatal care. Understanding these ultrasound findings can enhance awareness and guide effective medical management.
GA=21w5d: This label indicates the gestational age of the fetus, calculated as 21 weeks and 5 days. It helps determine the developmental stage, which is crucial for assessing the severity of fetal myelomeningocele.
8.3cm/1.3/28Hz: This specifies the measurement and settings of the ultrasound probe, with 8.3 cm indicating the depth, 1.3 the frequency, and 28Hz the frame rate. These parameters ensure clear imaging of the fetal spine and surrounding structures.

MI 1.2: This mechanical index value indicates the ultrasound’s intensity, set at 1.2, which is within safe limits for fetal imaging. It ensures minimal risk while maintaining image quality.
TIis 0.1: This thermal index value, at 0.1, measures potential heating effects, indicating a low risk to the fetus. It reflects the safety of the ultrasound procedure.
Dr. Moroder ecofetale.com: This credits the physician or website associated with the scan, Dr. Moroder, and provides a resource for further information. It signifies professional oversight of the imaging process.
2.Trim.F: This indicates the second trimester of pregnancy, aligning with the 21-week gestational age. It is a critical period for detecting structural abnormalities.
Har-alto 100: This likely refers to a high-resolution setting or adjustment on the ultrasound machine. It enhances the visibility of fine details in the fetal image.
Gn 1: This gain setting, set to 1, controls the brightness of the ultrasound image. A low setting ensures clear contrast for accurate diagnosis.
C6 / M5 P3 / E2 SRI II 3: These are additional machine settings, including color, mode, and speckle reduction imaging (SRI) level 3. They optimize the image quality for detailed analysis.
Understanding Fetal Myelomeningocele
Fetal myelomeningocele is a serious condition where the spinal cord and its protective covering protrude through an opening in the spine. This ultrasound image highlights the defect, often visible as a sac-like structure on the fetus’s back.
- The condition results from incomplete closure of the neural tube during early development.
- The arrow points to the protrusion, indicating where the spinal cord is exposed.
- It can lead to paralysis, bladder dysfunction, and hydrocephalus if untreated.
- Early detection at 21 weeks allows for planning interventions like fetal surgery.
- The 8.3 cm depth setting helps visualize the defect clearly in the second trimester.
Diagnosis and Imaging Techniques
Ultrasound technology plays a vital role in diagnosing fetal myelomeningocele. The settings and annotations provide valuable diagnostic clues.
- The Voluson E8 machine offers high-resolution imaging, essential for spotting subtle abnormalities.
- GA=21w5d confirms the timing, aligning with the second trimester screening.
- MI 1.2 and TIis 0.1 ensure safety while maintaining image quality.
- The Gn 1 and SRI II 3 settings enhance contrast and reduce noise.
- Regular scans can monitor the defect’s progression and plan delivery.
Clinical Management and Prognosis
Fetal myelomeningocele requires careful management to improve outcomes. Early diagnosis through ultrasound guides treatment decisions.
- Prenatal surgery can close the defect, potentially reducing hydrocephalus risk.
- Postnatal care may include shunt placement for excess cerebrospinal fluid.
- Physical therapy addresses muscle weakness and mobility issues.
- Genetic counseling helps assess recurrence risk in future pregnancies.
- Long-term prognosis depends on the defect’s size and location.
This ultrasound image of fetal myelomeningocele underscores the importance of prenatal screening in identifying neural tube defects early. The detailed annotations, from GA=21w5d to Dr. Moroder ecofetale.com, highlight the precision of modern imaging technology. By leveraging these insights, healthcare providers can offer timely interventions, improving the quality of life for affected individuals and their families.
