What Are the Prerequisites for Diagnostic Medical Sonography

Requirements for a physician to send a medical diagnostic ultrasound study

Some examples of medical conditions that can be diagnosed with ultrasound include:

  • Pregnancy: Ultrasound can be used to assess fetal growth and development, as well as to detect any potential issues.
  • Abdominal conditions: Ultrasound can be used to diagnose conditions such as gallstones, pancreatitis, and liver disease.
  • Cardiovascular conditions: Ultrasound can be used to evaluate the heart and blood vessels, as well as to diagnose conditions such as heart valve disease and congenital heart defects.
  • Gynecological conditions: Ultrasound can be used to diagnose conditions such as ovarian cysts, uterine fibroids, and endometriosis.
  • Urological conditions: Ultrasound can be used to diagnose conditions such as kidney stones, bladder infections, and prostate cancer.
  • Musculoskeletal conditions: Ultrasound can be used to diagnose conditions such as tendinitis, bursitis, and muscle tears.

In addition to the clinical suspicion of a condition, physicians may also send ultrasound studies to:

  • Confirm a diagnosis: Ultrasound can be a useful tool to confirm a diagnosis that has been clinically suspected.
  • Assess the progression of a condition: Ultrasound can be used to evaluate the progression of a medical condition over time.
  • Guide a medical procedure: Ultrasound can be used to guide medical procedures such as needle biopsies and punctures.

In general, doctors have the discretion to send ultrasound studies when they deem it necessary for patient care.

Patient Preparation for Ultrasound Studies:

  1. Abdominal Ultrasound:
    • Fasting: For abdominal ultrasounds, patients are often required to fast for a specified period before the examination. Fasting helps ensure a clear visualization of the abdominal organs, such as the liver, gallbladder, and pancreas. Typically, patients are asked not to eat or drink anything for 6 to 8 hours before the test.
    • Medication: Patients should inform their healthcare provider about any medications they are taking, especially if they are related to abdominal conditions. Depending on the case, the physician may advise patients to temporarily discontinue certain medications.
  2. Pelvic Ultrasound:
    • Bladder Filling: In the case of pelvic ultrasounds, especially for gynecological examinations, patients are often instructed to drink several glasses of water and refrain from urinating before the test. This helps fill the bladder and provides a better view of the pelvic organs, such as the uterus and ovaries.
  3. Renal (Kidney) Ultrasound:
    • Hydration: To facilitate imaging of the kidneys, patients may be advised to drink plenty of water before the test. Staying well-hydrated can help improve the clarity of the images.
  4. Vascular Ultrasound:
    • Clothing: Patients undergoing vascular ultrasound may need to wear loose-fitting clothing that allows easy access to the area being examined. For example, for a vascular study of the leg, the patient might need to wear shorts or a gown.
  5. General Preparation Tips:
    • Jewelry and Accessories: Patients should be advised to remove any jewelry or accessories in the area being examined, as they can interfere with the ultrasound probe.
    • Comfortable Clothing: Wearing comfortable clothing can help ensure a relaxed and stress-free experience during the ultrasound.

It’s crucial for patients to follow their healthcare provider’s instructions regarding preparation to obtain accurate results from the ultrasound study. Failure to comply with preparation guidelines can sometimes lead to inconclusive or suboptimal images, which may necessitate a repeat examination.

Before any ultrasound, patients should also inform their healthcare provider about any allergies, medical conditions, or medications they are taking, as this information can be essential for tailoring the ultrasound examination to their specific needs and ensuring their safety and comfort during the procedure.


In summary, medical diagnostic ultrasound studies are an essential tool in modern medical practice. Physicians can request these studies when they have a clinical suspicion of a condition that can be evaluated or diagnosed using ultrasound. The versatility of this technology spans from early detection of fetal development issues to the assessment of cardiovascular and musculoskeletal conditions.

With its safety, accessibility, and ability to guide medical procedures, ultrasound continues to play a crucial role in patient care and the advancement of medicine. As patients, we can rest assured that this tool will remain a valuable resource in diagnosing and treating diseases in the future.
