Level 2 Ultrasound: Detailed Anomaly Scan in Istanbul

Türkçe okuyun

Dr. Alparslan Demir · Obstetrics and Gynaecology

Level 2 ultrasound often raises a practical question: “I already have scans at my check-ups—why do I need this one?” I begin by reviewing your pregnancy dates and previous reports, then explain which anatomical assessments are complete and which still need planning. I want you to understand the report as well as the images.

When is it done, and what does it examine?

A detailed anomaly scan is commonly planned at 18–22 weeks; timing can vary with individual circumstances and local protocols. It systematically assesses the brain, face, spine, key heart structures, chest, abdominal wall, stomach, kidneys, bladder and limbs. Measurements, the placenta and amniotic fluid also contribute to the assessment. ISUOG: Mid-trimester scan guidance

How is it different from a level 1 scan?

The terms “level 1” and “level 2” are not used identically everywhere. A standard scan also assesses anatomy; a detailed or targeted examination follows a more extensive protocol. I therefore look at what was actually examined rather than relying on the label alone. A 3D/4D picture of the face does not establish that the anatomical assessment is complete.

What role does the Voluson E8 play?

High-resolution systems such as the Voluson E8 support detailed anatomical imaging with appropriate probes and settings. Doppler and volume-imaging functions may be used when indicated. The model does not determine diagnostic completeness by itself: operator experience, fetal position and imaging conditions remain important. GE HealthCare: Voluson E8 technical information

What happens after the scan?

I first review the findings with you and check whether any views remain incomplete. If findings are unremarkable, pregnancy follow-up continues. Incomplete views may require another scan. A suspected abnormality may lead to fetal medicine assessment, a focused examination of the heart or genetic counselling. Diagnostic testing is discussed where appropriate, including its benefits and risks. NHS: Anomaly scan and follow-up

Questions you may want to ask

They could not see everything. Does that mean something is wrong?

Not necessarily. Your baby’s position can prevent the required views. I explain which structures need another look and when that assessment should take place.

Does a normal scan guarantee a healthy baby?

No. Reassuring findings do not exclude every anomaly, genetic condition or problem that may develop later. Some small or later-developing structural changes cannot be identified at this examination.

Will it hurt, and how long does it take?

The examination is usually performed through the abdomen with gel and a probe. You may feel pressure. It often takes about 30 minutes, but obtaining the necessary views can take longer. Please say if you are uncomfortable.
