Functional MRI - Brain
Steps Involved in IVF:
Procedure Description
Functional MRI, or fMRI, is an advanced neuroimaging technique that measures and maps brain activity by detecting changes associated with blood flow. Unlike traditional MRI, which focuses on the anatomical structure of the brain, fMRI provides insights into brain functionality by capturing dynamic processes. It relies on the Blood Oxygen Level Dependent (BOLD) contrast, which highlights areas of increased brain activity due to heightened blood oxygenation. This technique is non-invasive, radiation-free, and provides both spatial and temporal information on brain activity.
The fMRI process generally involves scanning the brain while a person performs specific tasks, such as listening to music, solving problems, or visualizing images. These activities are designed to stimulate particular brain regions, and the fMRI detects how different brain areas respond. The resulting data aids in understanding brain networks, connectivity, and localized function, making it valuable for research, clinical diagnosis, and even planning neurosurgical interventions.
Functional MRI has grown to be a crucial tool in neuroscience, psychology, and medical research. It plays a pivotal role in diagnosing neurological conditions like epilepsy, Alzheimer's disease, stroke, and tumors. Additionally, fMRI is utilized to understand psychiatric disorders, language processing, sensory perception, and cognitive functions. Its application has become invaluable in pre-surgical mapping, where surgeons identify critical brain areas to minimize the risk of damage during operations.
Procedure Duration
The duration of an fMRI scan typically ranges from 30 minutes to an hour, depending on the complexity of the study and the number of sequences required. The procedure is usually divided into preparation, scanning, and recovery phases, with each phase offering a specific contribution to the overall process.
1. Preparation Phase:
Patients are first briefed about the procedure, including the tasks they might be asked to perform inside the scanner. To ensure accuracy, patients are asked to remove all metallic objects since the MRI machine uses a strong magnetic field. Comfortable positioning is crucial, as even small movements can compromise the quality of the images. This phase generally takes around 10-15 minutes.
2. Scanning Phase:
During this phase, the patient lies still in the scanner while the machine captures detailed images of brain activity. Depending on the study design, the patient may be asked to perform certain tasks, or stimuli may be introduced (visual, auditory, etc.). The scanning phase is typically 20-40 minutes long and may include multiple sequences, each lasting 5-10 minutes.
3. Post-Scan and Recovery Phase:
After the scan, patients can resume normal activities immediately as no recovery period is needed. The data acquired is then processed and analyzed by specialists to map brain function and identify any abnormalities. The duration of the post-scan phase is brief, as it usually involves only logistical activities, such as changing back into regular clothing and receiving any necessary follow-up instructions.

Risks & Considerations
- Metal and Electronic Device Interference: Patients with metallic implants, pacemakers, or other electronic devices should exercise caution as the MRI's magnetic field can interfere with such devices.
- Claustrophobia and Anxiety: The enclosed nature of the MRI machine may induce claustrophobia or anxiety in some patients. Open MRI machines are available in some centers for those who find traditional scanners uncomfortable.
- Noise and Discomfort: MRI scanners produce loud noises during the scan, which can be uncomfortable. Patients are usually provided earplugs or headphones to mitigate this issue.
- Motion Artifacts: Any movement during the scan can distort images, leading to reduced quality. Patients need to remain still for accurate results, which can be challenging during longer sequences.
- Limited Access for Certain Conditions: Patients with severe neurological or musculoskeletal disorders might face challenges in remaining still during the scan, potentially affecting the quality of the images.
How to Choose the Right Doctor and Hospital
When seeking the best facility and provider for an fMRI scan, consider the following:
- Accreditation and Expertise: Ensure that the hospital or imaging center has the necessary accreditation and that the radiologists and neurologists are highly experienced in neuroimaging. Look for providers with a track record in interpreting and conducting fMRI for diverse neurological conditions.
- Technology and Equipment: Advanced technology is crucial for precise imaging and accurate results. Select a facility equipped with the latest fMRI machines and software for data analysis to ensure that the brain activity is captured with clarity and precision.
By understanding the critical elements of the fMRI procedure, its duration, and benefits, as well as considering the potential destinations for high-quality care and evaluating the risks involved, medical professionals and patients can make informed decisions when seeking this crucial neuroimaging service.

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.
