Gallium-67 imaging in abdominal disease.

M F Hauser, P O Alderson

    Seminars in Nuclear Medicine
    |July 1, 1978
    PubMed
    Summary

    Gallium-67 imaging effectively detects abdominal inflammation like abscesses and infections, aiding in diagnosis. It also shows potential for identifying recurrent cancers, especially hepatomas and seminoma spread.

    Area of Science:

    • Nuclear Medicine
    • Diagnostic Imaging

    Background:

    • Intra-abdominal inflammation and neoplasms present diagnostic challenges.
    • Gallium-67 (67Ga) citrate is a radiopharmaceutical used in nuclear medicine.

    Purpose of the Study:

    • To evaluate the utility of Gallium-67 imaging in diagnosing intra-abdominal inflammation and neoplasms.
    • To assess the reliability and effectiveness of 67Ga imaging in specific abdominal conditions.

    Main Methods:

    • Gallium-67 imaging was performed on patients with suspected abdominal disease.
    • Image interpretation focused on detecting sites of inflammation (abscesses, infections) and neoplasms.
    • Comparison with other imaging modalities like ultrasound and CT was considered for anatomical detail.

    Main Results:

    • 67Ga imaging reliably detected intra-abdominal inflammation, including subphrenic abscesses, postoperative infections, pyelonephritis, perinephric abscesses, and peritonitis.
    • Detection rates for abdominal neoplasms were less impressive, with lymphoma detected in just over 50% of sites.
    • 67Ga demonstrated utility in detecting recurrence of 67Ga-avid neoplasms, particularly hepatomas and nodal spread of seminoma.

    Conclusions:

    • Gallium-67 imaging is a valuable tool for diagnosing intra-abdominal inflammation.
    • While less sensitive for primary abdominal neoplasms, 67Ga is effective for detecting recurrent 67Ga-avid tumors.
    • Selective use of 67Ga imaging in patients with suspected abscesses or recurrent neoplastic disease is recommended.
