Gynecologic Ultrasound — Seeing What the Exam Cannot
A gynecologic ultrasound uses sound waves to create real-time images of the uterus, ovaries, fallopian tubes, and surrounding pelvic structures. It is the most commonly ordered imaging study in gynecology — and at Lapeer Women’s Health, it is performed in-office by Dr. Andrei at both the Lapeer and Rochester Hills locations. No separate radiology facility visit required.
Ultrasound is not a replacement for a pelvic exam — it is a complement to it. The exam tells Dr. Andrei what she can feel; ultrasound tells her what she can see. Together, they provide a more complete picture of pelvic anatomy than either can provide alone. When ultrasound findings are inconclusive or a more detailed evaluation is needed, Dr. Andrei will order the appropriate next step — whether that is an MRI, a sonohysterogram, or an in-office procedure like hysteroscopy.
Gynecologic ultrasound at LWH is ordered when it will meaningfully change clinical management — not as a routine add-on to every appointment. When it is indicated, results are reviewed with you at the same visit whenever possible.
What Gynecologic Ultrasound Evaluates
These are the most common clinical indications for gynecologic ultrasound at Lapeer Women’s Health.
Uterine fibroids
Ultrasound identifies fibroid number, size, and location — submucosal, intramural, or subserosal — which determines whether they are likely contributing to heavy bleeding, pressure, or pain and what treatment is appropriate.
Ovarian cysts
Ultrasound characterizes cysts by size, morphology, and content — distinguishing simple functional cysts from complex or septated cysts that require closer follow-up or intervention.
Endometrial thickness
The endometrial stripe measurement is critical in evaluating postmenopausal bleeding and abnormal uterine bleeding. A thickened or irregular stripe prompts endometrial biopsy for tissue-based diagnosis.
Uterine polyps
Polyps within the uterine cavity are often identified on ultrasound as focal endometrial thickening or an echogenic lesion. Sonohysterography or hysteroscopy may follow for confirmation and removal.
PCOS evaluation
Polycystic ovarian morphology — the presence of 12 or more follicles per ovary or increased ovarian volume — is one component of the PCOS diagnostic criteria and is assessed by transvaginal ultrasound.
Pelvic pain evaluation
Ultrasound evaluates structural causes of pelvic pain including ovarian cysts, endometriomas, adnexal masses, and uterine abnormalities. It does not visualize endometriosis implants directly but identifies endometriomas.
Transvaginal vs. Transabdominal — What’s the Difference
Two types of gynecologic ultrasound are used at Lapeer Women’s Health. Dr. Andrei selects the appropriate type — or a combination of both — based on what needs to be evaluated.
- Transvaginal ultrasound (TVUS) — a small probe is placed in the vaginal canal, providing higher-resolution images of the uterus and ovaries due to proximity. Best for endometrial evaluation, early follicle counting, and ovarian detail.
- Transabdominal ultrasound — the probe is moved over the lower abdomen with the bladder full. Better for evaluating larger uteri, large fibroids, or when a broader pelvic view is needed.
- Both types use sound waves only — no radiation, no contrast dye, no sedation required.
- Most gynecologic ultrasounds at LWH are transvaginal — it provides the clearest view of uterine and ovarian anatomy.
- Patients who prefer transabdominal-only imaging can request this — discuss with Dr. Andrei at your visit.
“Ultrasound is the most useful tool I have for evaluating pelvic anatomy — but only when it’s ordered for the right reason. I want to know what the imaging will tell me that I don’t already know from the history and exam, and how it will change what we do next.”
- Ultrasound results reviewed with you at the same visit when possible
- Findings explained in plain language — not just a report sent to a portal
- Next steps determined based on what imaging shows — not deferred to a separate follow-up
- When MRI or sonohysterogram is the better tool, Dr. Andrei explains why and coordinates the order
- Images retained in your chart for longitudinal comparison at future visits
