TVS Scan vs Abdominal Ultrasound: What’s the Difference?

TVS scan vs abdominal ultrasound is a common question for many women when a doctor suggests an ultrasound. Both these tests use sound waves to see inside the body but they are done in different ways. An abdominal ultrasound is done on the stomach area from outside and a TVS (transvaginal scan) is done through the vagina to get a closer look at the uterus, ovaries, and other pelvic parts.

In this blog, we will explain everything about TVS scan vs abdominal ultrasound. We will also include what they are, how they are performed, their benefits, and more. This will help you to understand the role of each scan and more.

What is an Abdominal Ultrasound?

An abdominal ultrasound is very simple and safe, which uses sound waves to take pictures of the organs inside the stomach area, like the liver, kidneys, bladder, and pancreas. A small device called a probe is moved over the skin with the help of gel to get clear images.

Doctors suggest this scan if someone has stomach pain, swelling, or to check for any problems inside. It is also often done during pregnancy to see the baby’s growth. Since it does not use radiation and it is completely safe.

What is a TVS (Transvaginal) Scan?

A TVS scan is also called a transvaginal ultrasound. It is a test that helps doctors to see the female reproductive organs like the uterus, ovaries, cervix, and fallopian tubes. In this scan, a thin probe is gently placed inside the vagina. This gives clearer and closer images than an abdominal ultrasound.

Doctors often suggest a TVS scan to check reasons for irregular periods, infertility, pelvic pain, or early pregnancy health. It is a safe test, does not use radiation, and usually causes little or no discomfort.

Abdominal Ultrasound Procedure

In an abdominal ultrasound, the doctor uses a device called a transducer to look at the organs inside the belly, such as the liver, kidneys, bladder, and uterus. The patient is usually asked to lie down on a bed, and a water-based gel is spread on the stomach. This gel helps the sound waves to travel better and also gives clear pictures.

The doctor then moves the transducer over the stomach area and the images appear on a screen in real time. The test is painless, takes only a few minutes, and does not use any harmful radiation.

TVS Scan Procedure

In a TVS scan, a small ultrasound probe is gently inserted into the vagina to get a clear view of the uterus, ovaries, and nearby areas. The patient is usually asked to lie on the examination bed with knees slightly bent. A thin layer of gel is put on the probe and it is covered with a protective sheath before use.

The doctor then carefully places the probe inside the vagina and the images appear on a screen in real time. This scan is safe, does not cause much discomfort and also helps to detect even small changes that may not be visible in an abdominal scan.

Abdominal Ultrasound in Pregnancy

An abdominal ultrasound in pregnancy is a common test that helps doctors to see the baby growing inside the womb. In this scan, the mother is asked to lie down while a gel is spread on her stomach. A small device called a transducer is then moved over the belly and it shows live images of the baby on a screen.

This test is completely safe because it uses sound waves. It helps doctors to check the baby’s heartbeat, movement, growth, and position, along with the health of the uterus and placenta. Abdominal ultrasound is usually done at different stages of pregnancy to make sure the mother and baby are doing well.

TVS Scan in Pregnancy

A TVS (Transvaginal Scan) in pregnancy is a type of ultrasound where a small probe is gently placed inside the vagina to get clearer pictures of the uterus, ovaries, and early pregnancy. This method gives more detailed images, especially in the first few weeks when the baby is still very small.

The test is safe, does not cause harm to the baby, and usually takes only a few minutes. Doctors often suggest a TVS scan to confirm early pregnancy, check the heartbeat, measure the gestational sac, or find out the reason for bleeding or pain. It helps in understanding the pregnancy better and in making sure everything is progressing normally.

Pros & Cons of Abdominal Ultrasound

An abdominal ultrasound is a common test which is done during pregnancy and for checking other internal organs. It is very helpful but like any procedure, it has both advantages and risks. So, it’s very important to know about TVS scan vs abdominal ultrasound depending on the stage of pregnancy.

 

Pros of Abdominal Ultrasound

Cons of Abdominal Ultrasound

  

Non-invasive and painless

May not give clear images in very early pregnancy

Safe for both mother and baby (no radiation)

Image quality can be affected if the bladder is not full

Helps to monitor baby’s growth, heartbeat, and movements

Sometimes less detailed than TVS scan

Useful for checking placenta, amniotic fluid, and uterus

May miss very small structures in the first weeks

Quick and easy procedure

Sometimes requires follow-up with TVS for better clarity

Pros & Cons of TVS Scan

A transvaginal (TVS) scan is an ultrasound done through the vagina. It gives a closer and clearer view of the uterus, ovaries, and early pregnancy development. Doctors often compare TVS scan vs abdominal ultrasound to decide which method will give the best details at a given stage. But like any other test, TVS also has its own advantages and disadvantages.

 

Pros of TVS Scan
