Ultrasound imaging is an excellent tool for diagnosis in women’s health, particularly in terms of checking on reproductive organs or pregnancy monitoring. There are two general kinds of pelvic scans: transvaginal ultrasound and abdominal ultrasound. Both employ sound waves to produce images of internal structures but vary in their method of performance and purpose.
If you’re not sure which one is best for your case, here’s a summary of the main differences — and when each is usually suggested.
What Is an Abdominal Ultrasound?
An abdominal or transabdominal scan is an external scan taken over the lower stomach. It involves putting a gel onto the skin and passing a handheld probe (a transducer) across the abdomen. This is usually the method used early in pregnancy and then at subsequent times or for routine pelvic scans.
It’s usually the initial form of ultrasound done because it’s rapid, readily available, and doesn’t involve internal insertion. The pictures generated may be limited at times because of body configuration or the contents of the bladder, though.
What Is a Transvaginal Ultrasound?
A transvaginal ultrasound (TVS), however, employs a thin, wand-shaped probe placed inside the vaginal canal. This provides a closer and more distinct image of the uterus, ovaries, cervix, and other surrounding organs. Due to its closeness to these organs, it gives more precise and detailed images, especially in early pregnancy or when assessing gynecological issues.
Clinics that provide TV ultrasound in the Philippines usually prescribe this scan to identify reasons for irregular bleeding, pelvic pain, or infertility.
When Is Each One Recommended?
Abdominal Ultrasound Is Often Used For:
- Routine prenatal screening (particularly in the second and third trimester)
- Fetal growth monitoring
- General pelvic imaging
Transvaginal Ultrasound Is Preferred For:
- Early pregnancy evaluation (particularly before 10 weeks)
- Examining menstrual irregularity
- Diagnosis of cysts, fibroids, or endometriosis
- Monitoring follicle development in fertility treatment
Your doctor will choose the appropriate scan based on your symptoms, stage of pregnancy, or medical history. In some cases, both types may be done together for a more complete picture.
Which One Is Right for You?
Neither of the two scans is superior to the other — each has a different function. If you’re confused about what kind you need, it’s better to talk to a physician first. Online services such as NowServing PH can help you reach OB-GYNS who can walk you through the process, discuss your choices with you, and arrange the appropriate test at a reputable center.
Knowing the differences between these two types of ultrasounds will have you ready and comfortable before your appointment.
