Ultrasound (US) is the primary imaging tool for right upper quadrant pain, diagnosing cholecystitis and other conditions. Contrast-enhanced CT or MR imaging (MRCP) can complement US for specific limitations.

Area of Science:

  • Radiology
  • Medical Imaging

Background:

  • Acute right upper quadrant pain is a common clinical presentation.
  • Ultrasound (US) is frequently the first-line imaging modality used.

Purpose of the Study:

  • To evaluate the diagnostic utility of US in acute right upper quadrant pain.
  • To identify the limitations of US and suggest complementary imaging modalities.

Main Methods:

  • Review of US imaging findings in patients with acute right upper quadrant pain.
  • Comparison of US findings with other imaging modalities like CT and MRCP when necessary.

Main Results:

  • US accurately diagnoses acute cholecystitis and identifies various other causes of pain, including non-hepatobiliary conditions.

  • Limitations of US include incomplete visualization of the liver dome, subcostal areas, and biliary ducts.
  • Contrast-enhanced CT and MRCP (Magnetic Resonance Cholangiopancreatography) are valuable for specific challenging cases.

    • Conclusions:

    • US is a powerful and effective initial diagnostic tool for acute right upper quadrant pain.
    • Complementary imaging with CT or MRCP is recommended when US has limitations.
    • Tailoring imaging to the patient's clinical presentation and pain location is crucial for accurate diagnosis.
