CT Angiography
Steps Involved in IVF:
Procedure Description
CT Angiography (CTA) is a non-invasive medical imaging procedure used to visualize blood vessels and assess their health. It employs computed tomography (CT) technology combined with an injected contrast dye to produce detailed cross-sectional images of blood vessels, helping medical professionals diagnose conditions such as blockages, aneurysms, and other vascular abnormalities. CTA is widely used in various fields of medicine, including cardiology, neurology, and oncology, due to its ability to provide clear, accurate images without the need for traditional catheter-based angiography.
During a CTA, the patient is administered a contrast dye, usually iodine-based, which is injected into a vein. The dye travels through the bloodstream, highlighting the blood vessels in the resulting images. The CT scanner takes multiple X-ray images, which are then processed by computer software to create 3D images of the vascular system. These images allow physicians to examine the blood vessels in great detail, making it easier to detect abnormalities such as blockages, clots, or structural issues.
CT Angiography is highly valuable in assessing coronary arteries, cerebral arteries, and the aorta, among other vessels. The procedure is also employed to evaluate patients before surgeries or minimally invasive procedures. Its ability to detect arterial diseases early on helps in preventing severe conditions like strokes or heart attacks, making it an essential tool in modern diagnostic medicine.
Procedure Duration
The duration of CT Angiography is relatively short compared to other diagnostic procedures. The entire process, including preparation, typically lasts around 30 to 60 minutes. However, the actual scan time is much shorter, often taking just 5 to 10 minutes. Below is a detailed breakdown of the phases involved:
a. Pre-procedure Preparation
Before the scan, patients are briefed about the procedure. An intravenous (IV) line is placed, usually in the arm, through which the contrast dye will be administered. It's essential for the patient to remain still during the procedure, so the technician may provide instructions on breathing techniques to ensure clear images. Depending on the specific vessels being examined, patients may be required to fast for a few hours before the procedure.
b. During the Procedure
Once the patient is positioned on the CT table, the contrast dye is injected through the IV. Some patients may experience a warm sensation or metallic taste as the dye circulates. The CT scanner then takes a series of X-ray images, rotating around the patient to capture detailed views of the blood vessels. The process is painless, although some patients may feel slight discomfort from remaining still for the duration of the scan.
c. Post-procedure and Recovery
After the images are captured, the IV line is removed, and the patient can usually resume normal activities immediately. No special recovery time is required, but patients are advised to drink plenty of water to help flush the contrast dye from their system. In most cases, results are available within a few hours to a couple of days, depending on the complexity of the case and the facility.
Benefits of CT Angiography
- Non-invasive procedure: Unlike traditional angiography, CT Angiography does not require a catheter to be inserted into the arteries, making it a safer and less painful option.
- Detailed imaging: The high-resolution 3D images produced by CTA allow for accurate visualization of blood vessels and abnormalities, aiding in precise diagnosis.
- Quick and efficient: The procedure is relatively short, with minimal preparation and no significant recovery time needed.
- Early detection of vascular diseases: CTA can help detect blockages, aneurysms, and other vascular issues before they become life-threatening, contributing to better patient outcomes.
- Broad application: CT Angiography can be used to assess various vascular structures, including coronary arteries, brain arteries, and peripheral vessels.

Risks & Considerations
Although CT Angiography is generally safe, like any medical procedure, it does come with some risks and considerations. Below are a few points to keep in mind:
- Allergic reaction to contrast dye: Some patients may have an allergic reaction to the iodine-based contrast dye. In rare cases, this can lead to more severe reactions, such as anaphylaxis.
- Radiation exposure: Although the amount of radiation used in CT Angiography is relatively low, repeated exposure can accumulate over time, increasing the risk of developing certain types of cancer.
- Kidney function issues: Patients with pre-existing kidney problems may be at risk of contrast-induced nephropathy, a condition where the kidneys are damaged by the contrast dye.
- Not suitable for all patients: CT Angiography may not be appropriate for individuals with certain conditions, such as severe kidney disease or pregnancy, due to the risks associated with contrast dye and radiation.
- False positives or negatives: Although rare, there is a small chance that the results of CT Angiography may show false positives or negatives, potentially leading to unnecessary treatments or missed diagnoses.
How to Choose the Right Doctor and Hospital
When selecting a doctor or hospital for CT Angiography, it’s essential to prioritize expertise, technology, and patient care. Here are some practical tips:
Look for certified radiologists with specialized training: Ensure the medical professional performing the procedure is a certified radiologist with experience in vascular imaging. This ensures that the interpretation of the images is accurate and that any potential issues are detected early on.
Choose a hospital with advanced imaging technology: The quality of the CT scanner and imaging software can significantly impact the accuracy of the procedure. Look for hospitals or imaging centers with the latest generation CT scanners, as these provide higher resolution images and reduce radiation exposure.

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.
