    Technetium-99m-PIPIDA (99mTc-PIPIDA) scans accurately diagnose biliary tract disease, especially acute cholecystitis. This rapid hepatobiliary scan is reliable, even with jaundice, aiding in diagnosis and ruling out disease.

    Area of Science:

    • Nuclear Medicine
    • Diagnostic Imaging
    • Gastroenterology

    Background:

    • Biliary tract diseases require accurate and timely diagnosis.
    • Hepatobiliary scintigraphy is a key imaging modality.

    Purpose of the Study:

    • To validate technetium-99m-PIPIDA (99mTc-PIPIDA) for diagnosing biliary tract disease.
    • To assess the accuracy of 99mTc-PIPIDA in patients with suspected acute cholecystitis.

    Main Methods:

    • Prospective study of 117 patients with symptoms of acute cholecystitis.
    • Hepatobiliary scans using 99mTc-PIPIDA as an initial screening test.
    • Surgical pathology in 59 patients used for accuracy evaluation.

    Main Results:

    • Diagnostic accuracy for acute cholecystitis was 97%.

  • 100% accuracy in confirming complete common duct obstruction (12 patients).
  • Normal scans effectively ruled out acute cholecystitis; jaundice did not affect reliability.

    • Conclusions:

    • 99mTc-PIPIDA hepatobiliary scanning is a highly accurate, safe, and rapid diagnostic tool.
    • It is effective for diagnosing acute cholecystitis and common duct obstruction.
    • The test is reliable across different patient conditions, including jaundice.
