Dr. Atabak Allaei is a double board-certified physician in Vascular & Interventional Radiology and Diagnostic Imaging, a distinction that reflects advanced training in both diagnostic imaging and minimally invasive image-guided treatment. He serves as an attending physician at both Cedars-Sinai Medical Center in Beverly Hills and UCI Medical Center, and is the Medical Director of the California Fibroid Center.
Recognized for his expertise in uterine fibroid embolization and adenomyosis embolization, Dr. Allaei is respected in the field for his advanced technical skill, careful patient selection, and ability to manage complex embolization cases. Patients travel from across the country to seek his care for minimally invasive alternatives to major surgery, hysterectomy, or prolonged recovery.
As a vascular and image-guided specialist, Dr. Allaei has extensive experience in minimally invasive treatments for complex vascular and gynecologic conditions. He has developed a specialized approach to treating fibroids and adenomyosis, combining precise imaging, advanced embolization techniques, and individualized post-procedure management to help patients achieve meaningful symptom improvement while preserving the uterus.
Dr. Allaei has performed more than 5,000 image-guided procedures and has broad experience treating conditions involving the uterus, pelvis, lungs, liver, kidneys, bowel, bladder, tumors, and vascular system. This extensive procedural background allows him to approach even complex embolization cases with a high level of judgment, technical confidence, and attention to patient safety.
Originally from San Diego, California, Dr. Allaei earned his undergraduate degree in Biochemistry and Cell Biology from the University of California, San Diego, graduating Summa Cum Laude. He later pursued cancer research before earning his Doctor of Medicine degree from the State University of New York. He completed residency training in New York, followed by fellowship training in Vascular and Interventional Radiology at the prestigious Mallinckrodt Institute of Radiology at Washington University/Barnes-Jewish Medical Center.
Patients choose Dr. Allaei not only for his recognized expertise, but also for his personalized and honest approach to care. He takes time to understand each patient’s goals, explain treatment options clearly, and deliver advanced minimally invasive procedures with a strong focus on safety, comfort, and long-term outcomes.

Why patients seek our doctor
A method refined and proven across more than 2,000 embolizations — with a track record of successful outcomes that have spared women the hysterectomy or major surgery they were told was their only option.
Fibroids and adenomyosis are treated through a pinhole, with the uterus left intact. Every case is planned from his own reading of your MRI and performed by his own hand — which is why women fly in from other states and other countries rather than have it done closer to home.
He does every case himself
Every appointment and every procedure is conducted by Dr. Allaei — not a physician assistant, nurse practitioner or rotating provider.
He reads your MRI himself
Board certification in Diagnostic Imaging means he reads your MRI directly, rather than working from another radiologist’s report.
The right specialty for this procedure
Complex cases are routine
The uterus stays, whenever it can
Atabak Allaei, MD
Medical Director, California Fibroid Center
He reads your MRI. He plans your treatment. He performs your procedure. Every time — personally.
Women who were told hysterectomy was the only option
Real patients, in their own words — including women who had already been scheduled for surgery.
About Dr. Allaei
Focus: fibroids and adenomyosis
Dr. Allaei is recognized for his expertise in uterine fibroid embolization and adenomyosis embolization, and is respected in the field for his advanced technical skill, careful patient selection, and ability to manage complex embolization cases. He has developed a specialized approach that combines precise imaging, advanced embolization technique, and individualized post-procedure management — helping patients achieve meaningful symptom improvement while preserving the uterus. Adenomyosis is treated the same way — and because it is so often mistaken for fibroids, getting that diagnosis right is part of the work.
Patients travel from across the country to seek his care for minimally invasive alternatives to major surgery, hysterectomy, or prolonged recovery — for fibroids, for adenomyosis, or for both together.
Breadth of experience
Dr. Allaei has performed more than 10,000 image-guided procedures, including over 2,000 embolizations. That work spans well beyond the uterus — and within it covers both fibroids and adenomyosis:
This extensive procedural background is what allows him to approach even complex fibroid and adenomyosis cases with a high level of judgment, technical confidence, and attention to patient safety.
Why the specialty matters
Uterine fibroid and adenomyosis embolization is not a gynecologic surgery. Nothing is cut and nothing is removed — fibroids and adenomyosis are both treated from inside the blood vessels, through a pinhole, under live X-ray guidance. That is a vascular procedure, and it falls under the training and board certification of Vascular & Interventional Radiology.
It is worth being clear about this, because many women are only ever offered the options their gynecologist is trained to perform. OB-GYN certification covers surgical treatment — myomectomy, hysterectomy, ablation. Embolization is performed by interventional radiologists, which is why so many patients reach us having never been told the non-surgical option existed. Both specialties have a role; the difference is which procedures each is trained and certified to perform.
Training and credentials
He is double board-certified in Vascular & Interventional Radiology and in Diagnostic Imaging — a distinction reflecting advanced training in both diagnostic imaging and minimally invasive image-guided treatment. He serves as an attending physician at Cedars-Sinai Medical Center in Beverly Hills and UCI Medical Center, and is Medical Director of the California Fibroid Center.
How he practices
Originally from San Diego, Dr. Allaei is chosen by patients not only for his recognized expertise but for a personalized and honest approach. He takes time to understand each patient’s goals, explains every option clearly — surgical and non-surgical alike, for fibroids and adenomyosis both — and delivers advanced minimally invasive procedures with a strong focus on safety, comfort, and long-term outcomes.
Clinical decisions here are made by the physician who performs the procedure, with no outside influence on your care and no pressure to move you through a schedule. More about how our practice works →
Hear from current and past OR staff
The nurses and technologists who work beside him in the procedure room — the people who watch him operate — describe what it's like to assist his cases.
Patient reviews tell you about bedside manner. Operating-room staff see something patients never do: how a physician handles a difficult case, how steady the hands are, and whether the room stays calm.
About Dr. Allaei
Does Dr. Allaei perform the procedure himself?
Yes. He performs every fibroid and adenomyosis embolization personally, and conducts every appointment himself — not a physician assistant, nurse practitioner or rotating provider. The physician who reviews your imaging is the physician who treats you.
What is Dr. Allaei board certified in?
He is double board-certified in Vascular & Interventional Radiology and in Diagnostic Imaging.
This is the certification that matters for embolization — and it is not an OB-GYN certification. Uterine fibroid and adenomyosis embolization is not a gynecologic surgery. It is an image-guided vascular procedure, performed from inside the arteries through a pinhole, and it is trained for and performed by vascular and interventional radiologists — not by gynecologists, whose training covers surgical treatments such as myomectomy and hysterectomy.
His second certification, in Diagnostic Imaging, is why the same physician who reads your MRI is the one who performs your procedure.
How many procedures has he performed?
More than 10,000 image-guided procedures, including over 2,000 embolizations. That experience spans the uterus, pelvis, lungs, liver, kidneys, bowel, bladder, tumors and the vascular system — which is what allows him to take on complex fibroid and adenomyosis cases.
Do patients travel to see him?
Yes — patients travel from across the country and internationally. Appointments and imaging review are conducted by video telehealth, so out-of-area patients typically travel only once, for the procedure itself.
