MRI Pelvis Female (Routine) — Dictation, Appropriateness, and Dose for Residents

1. The High-Stakes Female Pelvis MRI Read

It’s a routine outpatient MRI of the female pelvis. The indication: “indeterminate adnexal mass on ultrasound.” The referring GYN needs to know if this is a simple hemorrhagic cyst that will resolve, a classic endometrioma, a benign dermoid, or something that needs an urgent oncology consult. Your attending expects you to nail the signal characteristics — T1 bright, T2 shading, fat saturation dropout — and correctly apply O-RADS MRI scoring if you see any suspicious solid components. This isn’t a stat read from the ED, but it’s a high-stakes interpretation where diagnostic precision changes patient management. Getting the key findings into a clean, structured report is non-negotiable.

When I was a resident, these were the cases where I’d double- and triple-check my search patterns. For more guides like this, check out our free trainee calculators and references.

2. What a Routine Female Pelvis MRI Covers and What Attendings Look For

A routine female pelvis MRI is the problem-solving modality for gynecologic imaging, typically ordered after an ultrasound is inconclusive. It provides superior soft tissue contrast without ionizing radiation, making it ideal for characterizing adnexal masses, mapping fibroids, and diagnosing conditions like adenomyosis and deep infiltrating endometriosis. The scan itself takes about 30-40 minutes with the patient supine, often after receiving an anti-peristaltic agent like glucagon to reduce bowel motion artifact.

Your attending will expect a comprehensive report that systematically evaluates the key pelvic structures and answers the specific clinical question. A thorough report should address:

• Uterus: Size, position, and morphology. Note any Müllerian anomalies (e.g., septate vs. bicornuate). Measure the junctional zone to assess for adenomyosis.
• Fibroids: A complete map including the number, location (submucosal, intramural, subserosal), size of the dominant fibroids, and any signs of degeneration. This is critical for pre-procedural planning for Uterine Artery Embolization (UAE) or myomectomy.
• Endometrium: Thickness and signal characteristics.
• Adnexa (Ovaries and Fallopian Tubes): Characterize any cysts or masses. Is it a simple cyst, a T1-bright hemorrhagic cyst, a fat-containing dermoid, or a classic endometrioma with T1 hyperintensity and T2 shading? For complex masses, describe solid components, enhancement, and any restricted diffusion.
• Endometriosis: Look for T1-bright implants in the posterior cul-de-sac, on the uterosacral ligaments, bowel, or bladder.
• Other Pelvic Structures: Briefly comment on the cervix, vagina, bladder, and any free fluid or lymphadenopathy. Always check the visualized bones for metastatic lesions.

3. Radiology Report Template for a Routine Female Pelvis MRI

This template provides a solid starting point for a comprehensive report. You can adapt it into a macro in your dictation software.

Technique

Multiplanar, multisequence magnetic resonance imaging of the female pelvis was performed without and with the administration of [x] mL of [contrast agent name] intravenous contrast. Sequences include: sagittal T2, axial T2, coronal T2, axial T1 pre-contrast, axial T1 fat-saturated pre-contrast, axial DWI/ADC, and axial 3D T1-weighted dynamic post-contrast images.

Findings

Uterus: Anteverted/retroverted. Measures [ ] x [ ] x [ ] cm. The junctional zone is [normal/thickened], measuring up to [ ] mm. The myometrium demonstrates [homogeneous signal/fibroids]. The endometrium measures [ ] mm in thickness.

Fibroids: [If present, describe number, location, and size of dominant fibroids. e.g., “There is a 3.4 cm intramural fibroid in the posterior body. A 2.1 cm subserosal fibroid arises from the fundus.” Note any degeneration.] If absent, state “No uterine fibroids are identified.”

Cervix: Unremarkable. No suspicious mass or fluid collection.

Right Ovary: Measures [ ] x [ ] x [ ] cm. [Describe follicles or any masses. e.g., “Contains a 2.5 cm T1 hyperintense, T2 hypointense lesion with shading, consistent with an endometrioma.” or “Normal in appearance.”]

Left Ovary: Measures [ ] x [ ] x [ ] cm. [Describe follicles or any masses. e.g., “Contains a 4.0 cm complex cystic lesion with a fat-containing nodule that demonstrates signal dropout on fat-saturated sequences, consistent with a dermoid cyst.” or “Normal in appearance.”]

Endometriosis: [No evidence of deep infiltrating endometriosis. / There are T1 hyperintense nodules along the uterosacral ligaments consistent with endometriotic implants.]

Bladder: Normal wall thickness. No intraluminal lesions.

Pelvic Sidewalls: No lymphadenopathy.

Free Fluid: [None/Physiologic amount of] free fluid in the cul-de-sac.

Visualized Bowel: Unremarkable.

Bones: No aggressive osseous lesion.

Impression

1. [Finding 1, e.g., “Right ovarian endometrioma measuring 2.5 cm.”]
2. [Finding 2, e.g., “Multiple uterine fibroids, the largest being a 3.4 cm intramural fibroid, as detailed above.”]
3. [Finding 3, e.g., “Thickened junctional zone, suspicious for adenomyosis.”]

4. Free Radiology Template Sources

Building your own template library is a rite of passage, but you don’t have to start from scratch. If you need templates for other modalities, two great free repositories exist. The Radiological Society of North America (RSNA) curates a comprehensive library at RadReport.org, which covers nearly every study you’ll encounter. Another excellent resource is Radiology Templates (AU), maintained by Australian radiologists.

5. The Next-Level Move: AI-Assisted Structured Reporting

The best reports are structured, consistent, and directly answer the clinical question. But manually formatting every finding during a busy shift is tedious. This is where AI-assisted tools can streamline your workflow. Instead of clicking through a structured template, you can dictate your positive findings in free form — “4 cm T1 bright, T2 shaded lesion in the right ovary consistent with endometrioma” — and the software structures it for you.

Tools like GigHz Precision AI are designed for this. It takes your natural language dictation of positive findings and organizes it into a clean, attending-ready report based on pre-loaded ACR and SIR templates. It helps ensure you don’t miss key elements and presents your findings in a logical, readable format.

6. When Should You Order a Routine Female Pelvis MRI? ACR Appropriateness Criteria

The American College of Radiology (ACR) provides evidence-based guidelines for imaging. For female pelvic conditions, MRI is often a second-line or problem-solving tool.

For an indeterminate adnexal mass found on ultrasound in a pre- or postmenopausal patient without acute symptoms, an MRI of the pelvis with and without contrast is rated “Usually Appropriate.” It is the gold standard for characterizing these lesions.

In cases of suspected endometriosis, an initial ultrasound is “Usually Appropriate.” However, if the ultrasound is indeterminate or negative and deep infiltrating endometriosis is suspected, or for treatment planning, a pelvic MRI is “Usually Appropriate” as the next step. For suspected rectosigmoid endometriosis specifically, MRI is also “Usually Appropriate” for initial imaging.

For uterine fibroids, ultrasound is the typical first-line imaging modality. When treatment like UAE or myomectomy is being planned, an MRI is “Usually Appropriate” to provide a detailed map of fibroid number, size, and location, which is critical for procedural success.

For acute pelvic pain, the guidelines are more nuanced. Ultrasound is almost always the first choice. MRI is generally not the initial imaging test for acute pain, whether gynecologic or non-gynecologic in origin, as CT and US are faster and more readily available.

7. Routine Female Pelvis MRI Protocol — Sequences, Contrast, and Key Parameters

A high-quality female pelvis MRI protocol is designed to maximize soft-tissue contrast and differentiate various pathologies. The key is using a combination of T2-weighted imaging as the anatomic workhorse, supplemented by T1-weighted sequences (especially with fat saturation) to identify blood and fat. Dynamic contrast-enhanced imaging helps characterize suspicious masses.

Below is a typical protocol. Note that slice thickness is kept thin (3-4 mm) for high-resolution evaluation of the endometrium, junctional zone, and ovarian morphology.

Common protocol pitfalls:

• Contrast Use: While a with-and-without contrast study is common for adnexal mass characterization, a non-contrast study is often sufficient for fibroid mapping or many cases of suspected endometriosis.
• Vaginal/Rectal Gel: Some institutions instill ultrasound gel into the vagina or rectum. Vaginal gel can help evaluate perineal or lower vaginal masses. Rectal gel is particularly useful for outlining the uterosacral ligaments and posterior cul-de-sac when evaluating for deep infiltrating endometriosis.
