What is Spinal/Sacral Ultrasonography?
Spinal or sacral ultrasonography is a method used in medicine to evaluate the spine and sacrum region. This imaging technique is especially preferred in children and infants because, as the bone structure is not yet fully hardened, internal structures can be clearly examined using sound waves. Being radiation-free makes it a reliable diagnostic method.
Spinal ultrasonography provides detailed imaging of the lower part of the spinal cord, nerve exit points, sacral canal, and surrounding tissues. It is used to evaluate structural abnormalities, congenital anomalies, or fluid accumulation in the spinal cord.
How is Spinal/Sacral Ultrasonography Performed?
During the examination, the patient is usually placed face down. Especially in infants, an appropriate position is given to keep the area being examined stable. A gel that facilitates the movement of the ultrasound probe is applied to the area, and the spinal cord and sacral canal are imaged using sound waves.
No pain or discomfort is felt during the procedure. The images obtained during the 15–20 minute examination are evaluated in detail by a specialist. It can be safely performed in pediatric patients without the need for sedation.
Why is Spinal/Sacral Ultrasonography Requested?
After birth, if a dimple, hair growth, skin discoloration, or swelling is observed on the back, ultrasonography may be requested. These findings can indicate hidden openings or developmental anomalies in the spinal cord. Early ultrasonography helps prevent serious issues that may develop later.
Additionally, spinal ultrasonography can be performed to evaluate symptoms such as urinary incontinence, leg weakness, or developmental delays. The physician may request detailed imaging of the spine and sacral region if suspicious findings are present.
What Diseases Can Be Detected by Spinal/Sacral Ultrasonography?
Examination can reveal congenital anomalies such as spina bifida occulta, which occurs when the spinal cord does not fully close. Cysts, fluid accumulation, or structures like lipomas in the spinal canal can also be visualized with ultrasonography.
Tethered cord syndrome, where the spinal cord is abnormally stretched downward, can be detected early using this method. Developmental disorders related to nerve exits in the sacral region, such as dermal sinus tracts, can also be seen through ultrasonography. These findings guide further testing and treatment planning.
Which Area is Examined in Spinal/Sacral Ultrasonography?
Spinal or sacral ultrasonography is used to examine the lower parts of the spinal system, particularly the lower back and sacrum (tailbone area). This method images the lower end of the spinal cord, nerve exit points, sacral canal, and surrounding soft tissues.
It plays an important role in investigating congenital anomalies. Especially when dimples, hair growth, or skin discoloration are observed on the sacral region, ultrasonography is performed to understand the underlying structural issues, clarifying whether there is a developmental anomaly in the lower spinal cord.
Who is Spinal/Sacral Ultrasonography Applied To?
This examination is mostly suitable for infants and young children. Because the bone structure is not fully hardened, sound waves pass through the spinal canal easily, and internal structures can be clearly examined. Therefore, it is particularly diagnostically valuable in the first 6 months of life.
In adults, sacral ultrasonography can be used in a limited way. While useful for evaluating soft tissues, the quality of images decreases as bone ossification progresses. The examination is also often requested by physicians for children with congenital anomaly findings on the back or with symptoms such as urinary incontinence or leg weakness.
How Long Does Spinal/Sacral Ultrasonography Take?
The examination is completed in a very short time, typically 15–20 minutes. Keeping the baby or child still allows the procedure to be performed quickly and effectively. Sedation is generally not required, and the examination can be easily completed with simple positioning.
No pain or discomfort is experienced during the procedure. The sound waves used are harmless and do not contain radiation. Once the necessary images are obtained, the results are evaluated quickly. In some cases, additional imaging such as MRI may be required for a more detailed assessment.
Spinal/Sacral Ultrasonography Prices 2026
Prices vary depending on the scope of the examination, the technology of the equipment used, and the city where the service is provided. Fees at private healthcare institutions are generally higher compared to state hospitals.
As of 2026, the price range for spinal/sacral ultrasonography is approximately 2000 TL to 5000 TL. If Doppler or advanced imaging is added, this fee may increase slightly. For precise pricing, confirmation should be obtained directly from the center where the examination will be performed.
What Are the Disadvantages of Spinal/Sacral Ultrasonography?
Although spinal or sacral ultrasonography is reliable and harmless, it has some limitations. In adults, the hardening of the bone structure makes it difficult for sound waves to penetrate internal structures, reducing image quality and limiting detailed evaluation. Therefore, it is not a preferred method in adults.
Another disadvantage is that the imaging may not always provide a definitive diagnosis. In some cases, ultrasonography only shows suspicious findings, which may need confirmation through advanced imaging methods such as MRI. Inexperienced operators may also increase the risk of misinterpretation.
Who Should Not Have Spinal/Sacral Ultrasonography?
While this method is easily used in infants and young children, it is generally not applied in adults. As the bone structure is fully developed, ultrasound waves cannot reach the sacral canal, making meaningful imaging impossible.
Additionally, ultrasonography may not be suitable for areas with severe skin infection or open wounds. The region must be clean and in proper condition to minimize infection risk. Although the risk of allergic reaction is very low, caution is advised for individuals sensitive to the gels used.
Post-Spinal/Sacral Ultrasonography Care
No special precautions are needed after the examination. Once the gel is removed, the patient can resume daily activities comfortably. Being radiation-free, it does not have any lasting effects on the body.
However, it is important for the results to be evaluated by a specialist to determine if further investigation is needed. If a suspicious finding is detected, the doctor may recommend advanced imaging like MRI. Correct interpretation of the report is crucial for the treatment process.
Does Spinal/Sacral Ultrasonography Cause Pain?
Ultrasonography is completely painless. During the procedure, only gel is applied, and slight pressure is applied with the probe. This pressure does not cause any pain. One of the main reasons it can be safely applied in infants and children is that it does not cause discomfort.
No sedation or anesthesia is required. If the child moves during the procedure, image quality may decrease, but this only slightly prolongs the process. Overall, the procedure is very comfortable and safe.
Does Spinal/Sacral Ultrasonography Provide Definitive Results?
This method provides highly reliable results, especially in infants, for examining the spinal cord and sacrum. Since the bone structure is not fully hardened, sound waves pass easily, allowing detailed imaging of the lower spinal cord. Therefore, examinations performed in the first 6 months of life have high diagnostic value.
However, it may not always provide a definitive diagnosis. Some structural anomalies or more complex disorders may be partially visible on ultrasound. In such cases, advanced imaging such as MRI is required. Therefore, ultrasonography is a reliable preliminary method but may need additional procedures to confirm the diagnosis.
Does Spinal/Sacral Ultrasonography Hurt?
The patient feels no pain during the procedure. Only gel is applied to the skin, and the ultrasound probe applies light pressure on the area. This pressure feels like normal touch. The painless nature of the procedure is especially important for safely performing it in infants.
The sound waves used do not harm the body. Patients can remain comfortable throughout the procedure. Therefore, spinal or sacral ultrasonography is a painless and safe imaging method.
Is Spinal/Sacral Ultrasonography Risky?
This method does not contain radiation, so it has no known harm. Its routine use in infants is evidence of its safety. The sound waves emitted by the ultrasound device do not damage the body or leave any permanent effects.
The main concern regarding risk is the ultrasound gel used. Very rarely, some individuals may have an allergic reaction. Other than that, the method has no risky aspects and is a safe, harmless diagnostic tool.
Who Performs Spinal/Sacral Ultrasonography?
This examination is performed by radiology specialist physicians. The radiologist operates the device to image the spinal cord and sacral region and reports the findings. In some cases, specialists experienced in pediatric radiology may be preferred.
Nurses or technicians may assist during preparation, but imaging and reporting are done by the specialist. The results are shared with physicians in related fields such as urology or neurosurgery.
Does Social Security Cover Spinal/Sacral Ultrasonography?
The Social Security Institution (SGK) covers ultrasonography tests requested for medical reasons. Spinal/sacral ultrasonography performed in state hospitals or SGK-affiliated private healthcare institutions can be provided free of charge if deemed necessary by a physician.
However, additional fees may be requested in private hospitals. Extra service fees may apply beyond what SGK covers. Therefore, it is important to confirm beforehand whether the facility has an SGK agreement and if any additional charges will be applied.
Is Spinal/Sacral Ultrasonography Performed with Contrast?
This method, used to evaluate the spine and sacral region, is performed using standard ultrasonography. No drugs or contrast agents are administered during the examination. Imaging is achieved using sound waves, making the procedure completely drug-free.
Some imaging methods use contrast through a vein to get clearer details, but spinal or sacral ultrasonography does not require this. Its safe, drug-free, and radiation-free nature is especially suitable for infants and children.
Should You Drink Water Before Spinal/Sacral Ultrasonography?
No special preparation is needed for this examination. Unlike kidney or bladder ultrasounds, a full bladder is not required. Therefore, the patient does not need to drink water before the procedure.
The main requirement is for the infant or child to remain calm during the exam to improve image quality. No fasting or fluid intake is required. Spinal/sacral ultrasonography is thus a practical and easy-to-perform method.
Is Spinal/Sacral Ultrasonography Available in State Hospitals?
This examination is available in state hospitals. Ultrasonography devices in radiology departments are used to perform spinal/sacral ultrasonography in infants and children. If covered by SGK, there is no charge.
However, some smaller hospitals may not have pediatric radiology specialists. In such cases, university hospitals or training and research hospitals are preferred. In major centers, this examination is routinely performed and referrals for advanced tests are provided if needed.
What Are the Side Effects of Spinal/Sacral Ultrasonography?
Since this method does not involve radiation, it has no serious side effects. The sound waves used do not harm the body, making it safe for use in infants. The most common minor issue is a cold sensation from the gel applied to the skin.
Very rarely, some individuals may develop an allergic reaction to the gel, causing redness or mild itching. No permanent or serious side effects have been reported. With these characteristics, spinal/sacral ultrasonography is a highly reliable and risk-free imaging method.
