Ultrasound Studies

We offer in-office ultrasound imaging for both obstetrical and gynecologic indications.

Please explore the following link to learn more about the use of ultrasound in obstetrics and gynecology.

Obstetrical Ultrasound


At Wilkerson OB/Gyn patients are typically scheduled for two ultrasounds during their pregnancy

  1. First trimester (approximately 8 weeks gestation) to establish viability and confirm the final due date
  2. Second trimester (approximately 18-20 weeks gestation) to survey the developing anatomy (if you want to know the gender of your baby we can share that with you at this visit!)
  3. Sometimes we prefer the second-trimester ultrasound to be done at the maternal fetal medicine specialist and will discuss and refer as appropriate

Medically Indicated

Additional ultrasounds are ordered at various times in the pregnancy when there is a medical or fetal indication (maternal diabetes, maternal hypertension, fetal growth concerns and many others)


It is exciting for us to be able to offer elective 3D/4D ultrasounds for a very special sneak peek of ultimate cuteness. There is no current medical indication for 3D/4D ultrasounds and the cost is not covered under insurance plans. Consequently, there is an out of pocket expense associated with this ultrasound. A prenatal package including photos and a CD is available to all interested patients. The optimal timing for an elective 3D/4D ultrasound is 27-32 weeks.

Gynecological Ultrasound

Transabdominal or Transvaginal

An ultrasound probe is placed on the abdomen and then a separate, more narrow probe is placed into the vagina in order to obtain images of the uterus, ovaries and surrounding tissues. This study is ordered by your doctor for many reasons including symptoms of pelvic pain, abdominal pain or abnormal bleeding. We typically plan for you to have the ultrasound done with our ultrasound technician and then to sit and review the results/decide on a treatment plan with your doctor during the same visit.


In certain cases, during a vaginal ultrasound, a sterile saline solution may be instilled into the uterine cavity through the cervix to improve visualization. This typically discussed and planned at the time the study is ordered.


“I LOVE this place! I had a different doctor office for my first son and they were terrible. I would get an appointment and wait over an hour. Here at Wilkerson I would get there and would go back immediately. They are very professional. Dr. Matthews and Dr. Flanagan are awesome! I had such a great pregnancy with my second son at this Dr. office. I would highly recommend them to other ladies looking for a great family friendly ob gyn! Rex Hospital is fantastic too!!!”

“I have been seeing the doctors at Wilkerson OBGYN for over 12 years. I delivered my two children with their doctors over the years. I have not had anything but wonderful experiences with their office. The front desk staff, the nurses, and the doctors are always helpful and courteous. I can call with questions for the advice nurse and am always called back quickly and with the answers to my questions. I refer my own patients to their practice and will continue to do so due to their excellent care that I have received.”

“I have had both my children with Wilkerson. Everyone there is always very kind and accommodating! So much so that I always miss not going after having my babies! The facilities are easy to access and always have ample parking! I love that it is right next to Rex hospital! Dr. Mong is my favorite doctor. Very smart and caring! Everyone is great!”

“I absolutely love this practice! Everyone is so nice and knowledgeable from the receptionist up front to the doctors! I never feel rushed and they always happy to answer any questions. They respond quickly to questions through their patient portal. Their phlebotomist is awesome! I hate needles and she is so friendly and talks to you to keep your mind off things! Truly an amazing practice!”
