Gynaecological Ultrasound

A gynaecological ultrasound (also called a pelvic ultrasound) is an imaging examination that uses sound waves to create real-time pictures of the pelvic organs, such as the uterus, ovaries, and fallopian tubes. It is a non-invasive procedure used to diagnose a variety of conditions, including pelvic pain, abnormal bleeding, ovarian cysts, and infertility. The scan is performed using one or both methods: an abdominal ultrasound (using a transducer on the abdomen) and/or a transvaginal ultrasound (using a transducer inserted into the vagina).

A gynaecological ultrasound (also called a pelvic ultrasound) is an imaging examination that uses sound waves to create real-time pictures of the pelvic organs, such as the uterus, ovaries, and fallopian tubes. The scan may be conducted using with either one or both techniques: an transabdominal ultrasound and/or a transvaginal ultrasound.

What the scan involves

  • Preparation: For an abdominal ultrasound, you may be asked to drink water to fill your bladder, which helps to provide a clearer view of the organs.
  • Procedure: A gel is applied to the skin of the lower abdomen, and a transducer (a handheld device) is moved over the area.
  • Transvaginal approach: In some cases, a transvaginal ultrasound will also be performed. A smaller transducer is inserted into the vagina to get a more detailed view of the uterus and ovaries.

Why it's performed

  • To investigate symptoms like pelvic or abdominal pain, abnormal or heavy bleeding, and bloating.
  • To assess fertility issues. The scan can check the size, shape, and position of the uterus and evaluate the lining (endometrium) for abnormalities.
  • To evaluate conditions like ovarian cysts or fibroids (benign tumors in the uterine muscle) and polyps (growths in the uterine lining).
  • To follow up on abnormalities felt during a physical exam. 

Endometriosis Ultrasound

An endometriosis ultrasound is a specialized, detailed imaging examination that uses high-frequency sound waves to look for signs of endometriosis, a condition where tissue similar to the uterine lining grows outside the uterus. It’s more in-depth than a routine gynaecological/pelvic ultrasound and helps diagnose and evaluate the severity of the condition by checking for cysts, assessing scar tissue, and evaluating the mobility of pelvic organs. A specialist sonographer often performs this scan, which can involve both transabdominal and transvaginal ultrasounds.

What the scan involves

  • Preparation: For an abdominal ultrasound, you may be asked to drink water to fill your bladder, which helps to provide a clearer view of the organs.
  • Transvaginal approach: In some cases, a transvaginal ultrasound will also be performed. A smaller transducer is inserted into the vagina to get a more detailed view of the uterus and ovaries. The sonographer will use a probe to create images, applying pressure to assess organ mobility.
  • They will look for endometriomas (cysts on the ovaries), assess the uterus for adenomyosis, and check other organs like the bowel and bladder for nodules.

Why it's more detailed than a gynaecological scan

  • This specialized scan is performed by sonographers with specific expertise in endometriosis.
  • It often combines transabdominal and transvaginal approaches for a more comprehensive view.
  • It is designed to detect the subtle signs of endometriosis, including changes in organ movement and the presence of deep nodules, which a standard ultrasound might miss. 
  • It should be noted that, while not all types of endometriosis are visible on ultrasound, this examination is a valuable, non-invasive tool to help diagnose and manage the condition.

Early pregnancy Ultrasound

An early pregnancy ultrasound, also known as a dating scan, is a medical imaging examination performed in the first trimester to confirm and monitor the progress of a pregnancy. These scans offer valuable information for both expectant parents and healthcare providers regarding the health and development of the embryo or fetus.

What the scan involves

For the abdominal ultrasound, you will be asked to drink water to fill your bladder, which helps to provide a clearer view of the pelvic organs and pregnancy. In some cases, a transvaginal ultrasound will also be also performed to obtain better views of the pelvic organs.

What the scan checks for

  • Pregnancy confirmation: Verifies the pregnancy is in the uterus and not outside the uterus
  • Heartbeat: Confirms the embryo is alive and growing by visualizing the fetal heartbeat, which should be visible from about six weeks onward.
  • Gestational age: Measures the embryo to accurately determine the number of weeks pregnant and calculate the estimated due date.
  • Multiple pregnancies: Determines if there is more than one baby, such as twins or triplets.
  • Uterine and ovarian health: Checks the uterus and ovaries for abnormalities like fibroids or cysts. 

When is it best performed

  • The scan is typically performed before 11 weeks, but ideally around 8 to 9 weeks to most accurately confirm the due date.
  • It can sometimes be performed as early as 6 weeks, but it’s not consistently possible to confirm fetal heart activity before this time. 

Viability Scan:

Similar to the early pregnancy scan the viability scan is usually carried out between 6 and 10 weeks of pregnancy, a viability scan confirms the presence of a heartbeat, the embryo’s location within the uterus (ruling out ectopic pregnancy), and estimates gestational age. This scan is crucial for providing reassurance, especially in cases of pain, bleeding, previous miscarriage, or uncertainty about dates.

When and how it's done

  • Timing: The ideal time is between 7 and 9 weeks for the most accurate dating and to clearly see the fetal heartbeat.
  • Procedure: The scan is usually performed using both transabdominal and transvaginal ultrasound for better image quality in early pregnancy.

Saline Sonography

Saline sonography, also known as saline infusion sonohysterography (SIS or SHG), is a specialized ultrasound technique used to evaluate the uterus. During this procedure, a small amount of sterile saline solution is gently infused into the uterine cavity through a thin catheter while transvaginal ultrasound imaging is performed.

The infusion of saline helps to expand the uterine cavity, providing a clearer view of the endometrial lining and allowing for more detailed visualization than standard ultrasound alone. This enhanced detail can help detect abnormalities such as polyps, fibroids, adhesions, or abnormal uterine shapes that might be contributing to symptoms like abnormal uterine bleeding, infertility, or recurrent pregnancy loss.

Saline sonography is generally well-tolerated, minimally invasive, and does not require anesthesia. Some women may experience mild cramping during or after the procedure. It is usually performed in the first half of the menstrual cycle, after menstruation but before ovulation, to avoid interfering with a potential early pregnancy.

It is an important tool in gynaecological evaluation, providing valuable information for both diagnosis and treatment planning.

HyCoSy

HyCoSy (hystero-salpingo contrast sonography) is a specialised ultrasound procedure used to assess the fallopian tubes and confirm if they are open or blocked. It involves using contrast fluid during a transvaginal ultrasound, making it a safe and effective way to evaluate tubal patency and diagnose certain structural issues within the female reproductive system. This test is commonly used in fertility investigations. Detailed instructions will be provided to you on booking in for this examination.

Hystero-salpingo contrast sonography also known as HyCoSy, is a specialised ultrasound procedure that is used to assess the fallopian tubes and confirm if they are open or blocked.

What the Procedure Involves:

  • Using contrast fluid during a transvaginal ultrasound to evaluate tubal patency and diagnose certain structural issues within the female reproductive system.
  • The contrast fluid is gently infused through a fine tube into the cervix while a transvaginal Ultrasound examination is performed.
  • Preparation includes timing the test during your menstrual cycle (usually days 5–12) and taking pain relief beforehand, if necessary.
  • Detailed instructions will be provided to you on booking in for this examination.

Why It's Performed:

  • To diagnose structural issues within the female reproductive system that may contribute to infertility.
  • Most importantly to assess whether the fallopian tubes are open (tubal patency) or blocked.

This test is commonly used in fertility investigations, and most patients can return to normal activities the same day.

Testicular Ultrasound

A testicular ultrasound is used as part of the evaluation for male fertility issues. It provides detailed images of the testicles, epididymis, and surrounding scrotal structures, helping doctors identify physical problems that might affect sperm production or transport. The procedure is safe, does not use radiation, and is usually painless.

What the scan involves

  • Preparation: No preparation is needed for this examination.
  • Procedure: You will lie on your back, and a clear gel will be applied to the scrotum. The gel may feel cold. A sonographer will move a handheld probe (transducer) over the area.
  • The scan itself is painless, though you may feel some discomfort if there is an underlying painful condition. Afterward, you can return to your normal activities. 

Why it's performed

  • To check for blockages and issues in the tubes that transport sperm.
  • To diagnose varicoceles (Enlarged veins in the scrotum that can impair sperm production).
  • To identify and classify testicular masses that may require further investigation.
  • To locate a testicle that has not moved into the scrotum (undescended testicle)
  • To accurately measure the size of the testicles, as small testicular volume can be a sign of infertility.

The above indications are only some of the reasons why a testicular ultrasound is carried out. It is a primary diagnostic tool to evaluate testicular health and pinpoint problems with sperm production or delivery that may impact fertility. 

3D gynaecology uss:

A 3D gynaecology ultrasound is an advanced imaging technique that creates detailed three-dimensional images of the female reproductive organs. This technology allows for clearer and more accurate visualisation of the uterus, ovaries, and surrounding structures compared to traditional 2D ultrasounds. 3D ultrasound is particularly useful for evaluating complex conditions such as uterine abnormalities, polyps, fibroids, and congenital anomalies. It assists both patients and healthcare providers in understanding anatomy and planning appropriate treatment, all while remaining safe and non-invasive.

Usually carried out between 6 and 10 weeks of pregnancy, a viability scan confirms the presence of a heartbeat, the embryo’s location within the uterus (ruling out ectopic pregnancy), and estimates gestational age. This scan is crucial for providing reassurance, especially in cases of pain, bleeding, previous miscarriage, or uncertainty about dates.

Nuchal Translucency (NT) Scan:

Conducted between 11 and 14 weeks, the NT scan measures the fluid at the back of the baby’s neck. An increased thickness can indicate a higher risk of chromosomal conditions such as Down syndrome. The NT scan is often combined with other tests for a comprehensive first-trimester screening.

3D/4D Early Pregnancy Scans:

While standard early pregnancy scans use 2D imaging, some clinics offer advanced 3D and 4D scans. A 3D scan creates a three-dimensional image of the gestation , providing more detailed visualisation of anatomy. A 4D scan shows real-time, moving images. These technologies can offer clearer views of the gestational sac, yolk sac, and early fetal structures, though they are not always necessary for routine assessment.

Benefits:

Early pregnancy scans offer reassurance about early fetal development, help detect multiple pregnancies, and may identify certain structural problems at an early stage. They can also help estimate the expected due date more accurately.

In summary, early pregnancy scans (including viability, NT, and 3D/4D imaging) are safe, non-invasive, and play a vital role in early prenatal care, ensuring both maternal and fetal wellbeing.

Endometriosis uss:

An endometriosis ultrasound is a specialised imaging examination designed to detect signs of endometriosis, a condition where tissue similar to the lining of the uterus grows outside the womb. This ultrasound, often performed transvaginally, can help identify endometriomas (ovarian cysts related to endometriosis), as well as detect deep infiltrating endometriosis affecting pelvic organs. While not all types of endometriosis are visible on ultrasound, this scan is a valuable, non-invasive tool to help diagnose and manage the condition.

HyCoSy with lipidol:

HyCoSy with Lipiodol is a specialised ultrasound procedure that uses Lipiodol, an oil-based contrast agent, to evaluate the openness (patency) of the fallopian tubes. During this test, Lipiodol is gently introduced into the uterus and fallopian tubes while their flow is monitored using ultrasound imaging. In addition to providing clear images, some studies suggest Lipiodol may even improve fertility in some women after the procedure. HyCoSy with Lipiodol is safe, minimally invasive, and commonly used as part of fertility assessments.

Testicular ultrasound:

A testicular ultrasound is sometimes used as part of the evaluation for male fertility issues. It provides detailed images of the testicles, epididymis, and surrounding scrotal structures, helping doctors identify physical problems that might affect sperm production or transport.

Common reasons to perform a testicular ultrasound in the context of male fertility include:

Detecting varicoceles: Enlarged veins in the scrotum (varicoceles) are a common cause of male infertility, and ultrasound can diagnose their presence and severity.

Finding structural abnormalities: Ultrasound can identify testicular atrophy (shrinking), tumors, cysts, or undescended testes, all of which might impact fertility.

Evaluating blockages or obstructions: The scan can help detect blockages in the tubes that carry sperm.

Assessing inflammation or infection: It can help diagnose epididymitis (inflammation of the epididymis) or orchitis (inflammation of the testicle), both of which could affect fertility.

The procedure is safe, does not use radiation, and is usually painless. It gives valuable information alongside other fertility tests such as semen analysis and hormone assessments, helping guide treatment decisions for men experiencing infertility.
