Transcranial Dopplers
Steps Involved in IVF:
Procedure Description
Transcranial Doppler (TCD) ultrasound is a non-invasive imaging technique used to assess the blood flow in the brain's major arteries. TCD plays a crucial role in diagnosing and monitoring various neurological conditions, including cerebrovascular diseases, brain aneurysms, and traumatic brain injuries. By utilizing sound waves, the procedure measures the speed and direction of blood flow within the brain’s arteries, providing vital information without the need for radiation or contrast agents.
During the TCD procedure, a device called a transducer is placed over areas of the skull where the cranial bone is thinner. This placement allows the ultrasound waves to pass through the bone and access the underlying arteries. The ultrasound waves emitted by the transducer penetrate the skull, and when they encounter moving blood cells, they bounce back to the device at different frequencies, creating a Doppler shift. These frequency changes are then analyzed to determine blood flow characteristics, revealing any abnormalities or blockages within the brain’s vascular network.
TCD is particularly valuable in detecting conditions like stroke risk, vasospasms, and the effectiveness of treatments in patients with sickle cell disease. It is also used as a follow-up tool in neurosurgical procedures and can even help determine brain death in critical cases. Unlike MRI or CT scans, TCD is less costly, requires no radiation exposure, and can be conducted repeatedly over time, making it an attractive option for both initial diagnosis and ongoing monitoring.
Procedure Duration
The Transcranial Doppler procedure typically lasts between 30 minutes to an hour, depending on the patient's condition and the number of arteries being examined. The process involves a few stages, each carefully designed to ensure accurate results. Initially, the technician or physician will position the patient comfortably, often reclining, with the head supported. A water-based gel is then applied to the transducer, ensuring optimal contact between the skin and the device.
Once the procedure begins, the transducer is gently placed over specific areas of the skull, typically the temporal region, the back of the head, and sometimes the eye sockets. During this phase, the clinician may ask the patient to remain still or make slight head adjustments to help capture optimal images of the blood vessels. For each artery, the transducer’s angle and location may be adjusted multiple times to gather accurate data on blood flow.
Recovery time is virtually non-existent with TCD, as the procedure is entirely non-invasive. Patients can immediately return to their daily activities without restrictions or the need for additional recovery measures. Unlike other diagnostic imaging, TCD requires no anesthesia, injections, or radiation, making it highly accessible for repeated monitoring and routine check-ups.
Benefits

Risks & Considerations
- Quality of Equipment: Ensure the facility uses high-quality ultrasound equipment, as older or low-resolution devices may yield inaccurate results.
- Technician Experience: Since TCD is highly operator-dependent, the accuracy of the results relies significantly on the skill and expertise of the technician or physician performing the scan.
- Limited Visualization: While effective for many conditions, TCD cannot visualize blood vessels within the skull as clearly as CT or MRI, which may be necessary for more detailed diagnoses.
- Not Suitable for All Conditions: TCD is best for monitoring blood flow rather than providing detailed images of brain structures, so it may not replace other imaging techniques in complex cases.
- Variability in Interpretation: The interpretation of TCD results may vary, so patients should seek facilities with reputable specialists in neurological diagnostics to ensure accurate reading and analysis of their results.
How to Choose the Right Doctor and Hospital
When selecting a provider for Transcranial Doppler, consider the facility's reputation for neurological diagnostics, especially the experience level of its staff in handling TCD. Ideally, choose a hospital or clinic with a dedicated neurology department and a team of professionals trained specifically in Doppler ultrasound for brain imaging. Experienced radiologists and technicians play a vital role in ensuring accurate and consistent results, so prioritize facilities with specialists in this area.
Moreover, look for institutions that prioritize patient safety and use up-to-date, high-quality equipment. Modern ultrasound machines designed for cranial imaging will yield the most reliable data. Checking for internationally recognized accreditation, while not specifically listed here, can also indicate high standards, but ultimately, professional reputation and transparency in healthcare practices should be key deciding factors.

Frequently Asked Questions
What actually happens during hyperstimulation of the ovaries?
The patient will take injectable FSH (follicle stimulating hormone) for eight to eleven days, depending on how long the follicles take to mature. This hormone is produced naturally in a woman’s body causing one egg to develop per cycle. Taking the injectable FSH causes several follicles to develop at once, at approximately the same rate. The development is monitored with vaginal ultrasounds and following the patient’s levels of estradiol and progesterone. FSH brand names include Repronex, Follistim, Menopur, Gonal-F and Bravelle. The patient injects herself daily.
What happens during egg retrieval?
When the follicles have developed enough to be harvested, the patient attends an appointment where she is anesthetized and prepared for the procedure. Next, the doctor uses an ultrasound probe to guide a needle through the vaginal wall and into the follicle of the ovary. The thin needle draws the follicle fluid, which is then examined by an embryologist to find the eggs. The whole process takes about 20 minutes.
What happens to the eggs?
In the next step, the harvested eggs are then fertilized. If the sperm from the potential father, or in some cases, anonymous donor, has normal functionality, the eggs and sperm are placed together in a dish with a nutrient fluid, then incubated overnight to fertilize normally. If the sperm functionality is suboptimal, an embryologist uses Intracytoplasmic Sperm Injection to inject a single sperm into a single egg with an extremely precise glass needle. Once fertilization is complete, the embryos are assessed and prepared to be transferred to the patient’s uterus.
How are the embryos transferred back to the uterus?
The doctor and the patient will discuss the number of embryos to be transferred. The number of successfully fertilized eggs usually determines the number of eggs to be placed in the uterus. Embryos are transferred to the uterus with transabdominal ultrasound guidance. This process does not require anesthesia, but it can cause minor cervical or uterine discomfort. Following transfer, the patient is advised to take at least one days bed rest and two or three additional days of rest, then 10 to 12 days later, two pregnancy tests are scheduled to confirm success. Once two positive tests are completed, an obstetrical ultrasound is ordered to show the sac, fetal pole, yolk sac and fetal heart rate.
Embryoscope©
Built into this technology there is a microscope with a powerful camera that allows the uninterrupted monitoring of the embryo during its first hours of life. In this way, we can keep a close eye on the embryo, from the moment when the oocyte is inseminated and begins to divide into smaller and smaller cells, until it can be transferred to the uterus.
