Pelvic Ultrasound

A pelvic ultrasound uses sound waves to examine pelvic organs and can be performed through the lower abdomen or with an internal probe.

The probe sends and receives sound waves, and software turns the echoes into moving images. The examination can show the size, shape, position, and blood flow of organs such as the uterus and ovaries.

For an abdominal scan, you lie on your back while gel is placed on the lower abdomen. The sonographer moves a handheld probe over the skin. A comfortably full bladder may help create a clearer viewing window, so you may be asked to drink fluids beforehand.

An internal scan uses a slender covered probe placed gently in the vagina. You change privately, receive instructions, and can discuss consent or discomfort throughout. Tell the sonographer if you need a pause or if an internal examination is not suitable for you.

Diagnostic ultrasound does not use ionising radiation. It is widely used to examine pelvic structures, including during pregnancy when clinically appropriate. The quality of the images depends on the body area, bladder preparation, probe position, and what the scan is intended to assess.

Ultrasound can identify many structural changes, but it cannot settle every diagnosis. The clinician interprets the report with your symptoms, examination, menstrual history, and other tests. A normal scan may still need follow-up when symptoms continue.

An abnormal report may describe a cyst, fibroid, thickened lining, unusual blood flow, or a finding that needs a closer look. It does not by itself establish the cause. Your clinician will explain whether the finding fits your symptoms and whether it needs monitoring or further assessment.

Next steps can include repeat ultrasound, blood tests, examination, MRI, or a tissue sample. Ultrasound may help assess an [Imperforate Hymen](/conditions/imperforate-hymen/) or investigate a pelvic finding that requires further evaluation. A scan can also be part of assessing symptoms where [Ovarian Cancer](/conditions/ovarian-cancer/) is one of several possible diagnoses.

The examination is often performed without sedation and usually allows you to leave soon afterwards. The sonographer may take images from several angles and use Doppler imaging to assess movement of blood through selected vessels.

A clinician may request pelvic ultrasound for pelvic pain, unusual bleeding, fertility assessment, pregnancy-related questions, or a suspected change involving the uterus or ovaries. It can also investigate an examination finding or monitor a known issue over time.

Tell the service about pregnancy, recent procedures, allergies to products used during the examination, and whether an internal scan may be difficult or unacceptable for you. This helps the team plan the appointment respectfully.

The appointment usually follows these steps: review the request and preparation instructions; expose only the area being examined; lie in the required position; allow gel or a covered probe to be used; hold still while images are collected; and receive instructions about what happens next.

The sonographer may ask you to change position or briefly empty your bladder between abdominal and internal views. Images are sent for interpretation rather than diagnosed solely at the bedside.

There is usually no recovery period after a standard ultrasound. You can generally return to your usual activities. Mild temporary pressure or tenderness may occur after an internal examination; contact your healthcare team if pain, bleeding, or other symptoms concern you.

External ultrasound may feel cold from the gel or uncomfortable from pressure on a tender area. An internal examination can feel intrusive or uncomfortable, and you can ask for it to stop. Ultrasound may not show every structure clearly, particularly when bowel gas or body position limits the view.

Depending on the clinical question, alternatives may include an examination, blood tests, MRI, computed tomography, or follow-up imaging. An internal ultrasound can provide a closer view, while an abdominal approach may be preferred in some situations. The choice depends on symptoms, pregnancy status, consent, and the detail needed.

Look for a service that explains preparation, offers a choice of approach when clinically possible, protects your privacy, and has a clear pathway for sending the report to your clinician. Bring relevant previous reports and ask who will discuss the findings with you.
