When a doctor recommends an ultrasound to examine the pelvic region, you may come across different scanning methods. Two commonly used options are a pelvic scan and a transvaginal scan. Although both use ultrasound technology, they differ in how the examination is performed and the type of images they provide.
Understanding the Pelvic Scan vs Transvaginal Scan comparison can help you understand why a particular scan may be recommended and what to expect during the examination.
What Is a Pelvic Scan?
A pelvic scan is an ultrasound examination used to evaluate organs and structures in the pelvic region. It is generally performed by moving an ultrasound probe over the lower abdomen.
What Does a Pelvic Scan Examine?
A pelvic ultrasound can provide images of:
- Uterus
- Ovaries
- Urinary bladder
- Endometrium
- Surrounding pelvic structures
It may be recommended for pelvic pain, abnormal bleeding, menstrual irregularities, or suspected abnormalities involving the reproductive organs.
What Is a Transvaginal Scan?
A transvaginal scan is a specialized ultrasound examination performed using a slim ultrasound probe that is gently inserted into the vagina.
How Is a Transvaginal Scan Performed?
The probe is wrapped in a protective sheath and also given some lubricating gel before it’s inserted. Since the probe is placed nearer the uterus and ovaries, transvaginal ultrasound can usually give more detailed views of those structures, in a way that feels more “close up” than usual.
The procedure is generally quick, although some patients may experience mild pressure or temporary discomfort.
Pelvic Scan vs Transvaginal Scan: Key Differences
The main Difference between pelvic and transvaginal ultrasound is the position of the ultrasound probe.
A pelvic scan kind of uses an external way, through the lower abdomen, so it stays outside, and a transvaginal scan is more internal; you know, it goes inside. Which one gets chosen kind of depends on what organs you have to see, and also on how exact that detail really needs to be, like how fine it has to look.
Pelvic Scan vs Transvaginal Scan Comparison
Feature | Pelvic Scan | Transvaginal Scan |
Probe position | Over the lower abdomen | Inside the vagina |
Approach | External | Internal |
Image detail | Provides a general pelvic view | Often provides more detailed views |
Invasiveness | Non-invasive | Minimally invasive |
Bladder preparation | Usually requires a full bladder | Usually requires an empty bladder |
Common purpose | General pelvic assessment | Detailed reproductive-organ assessment |
What Can a Pelvic Scan Detect?
A pelvic ultrasound can help evaluate the uterus, ovaries, bladder, and other pelvic structures.
Common Reasons for a Pelvic Scan
A pelvic ultrasound for the uterus and ovaries may be recommended to investigate:
- Uterine fibroids
- Ovarian cysts
- Abnormal uterine bleeding
- Pelvic pain
- Changes in the uterine lining
- Certain ovarian abnormalities
- Enlarged pelvic organs
Ultrasound findings should always be interpreted by a qualified healthcare professional alongside symptoms and medical history.
When Is a Transvaginal Scan Recommended?
A transvaginal scan may be recommended when more detailed imaging of the uterus, endometrium, or ovaries is required.
Common Reasons for Transvaginal Ultrasound
Doctors may recommend it for:
- Abnormal vaginal bleeding
- Pelvic pain
- Ovarian abnormalities
- Evaluation of the endometrium
- Certain gynecological concerns
- When an abdominal scan does not provide sufficient detail
Can You Have Both Types of Scans?
Yes. In some cases, a healthcare professional may recommend both examinations.
Why Are Both Scans Sometimes Used?
A pelvic scan can provide a broader overview of the pelvic region, while a transvaginal scan can provide closer and more detailed images of specific reproductive organs.
Therefore, neither examination is universally “better.” The appropriate scan depends on the patient’s symptoms and the doctor’s diagnostic requirements.
How to Prepare for These Ultrasound Scans?
Preparation depends on the type of examination being performed.
Preparation for a Pelvic Scan
For a transabdominal ultrasound, you may be asked to drink water before the examination and arrive with a full bladder. Follow the preparation instructions provided by your diagnostic centre.
Preparation for a Transvaginal Scan
For a transvaginal examination, you are generally asked to empty your bladder before the scan. Your healthcare provider or diagnostic centre will explain the specific preparation required.
Pelvic Scan vs Transvaginal Scan: Which One Do You Need?
The answer depends on what your doctor needs to evaluate. A pelvic scan may be suitable for a general assessment, while a transvaginal scan can provide more detailed imaging of structures such as the uterus, endometrium and ovaries.
In some situations, both approaches may be used to obtain a more comprehensive assessment.
Choose the Right Diagnostic Centre for Your Scan
