Gallbladder bile in cholecystitis: in vitro MR evaluation.

T G Loflin, J F Simeone, P R Mueller

    Radiology
    |November 1, 1985
    PubMed
    Summary

    Proton magnetic resonance (MR) relaxation times do not reliably differentiate acute from chronic cholecystitis. Bile concentration was higher in chronic cholecystitis patients, but protein content varied widely.

    Area of Science:

    • Gastroenterology
    • Medical Imaging
    • Biochemistry

    Background:

    • Cholecystitis, an inflammation of the gallbladder, can be acute or chronic.
    • Accurate differentiation between acute and chronic cholecystitis is clinically important for treatment decisions.

    Purpose of the Study:

    • To investigate if proton magnetic resonance (MR) relaxation times (T1 and T2) can differentiate between acute and chronic cholecystitis.
    • To assess bile concentration and protein content in relation to cholecystitis type.

    Main Methods:

    • Collected 53 gallbladder bile samples from patients undergoing cholecystectomy for acute or chronic cholecystitis, plus 5 from normal gallbladders.
    • Measured proton magnetic resonance (MR) relaxation times (T1 and T2), protein content, and water content.
    • Analyzed data based on pathological diagnosis: 11 acute cholecystitis, 41 chronic cholecystitis, 6 normal.

    Main Results:

    • No significant difference was found in mean T1 and T2 relaxation times between acute and chronic cholecystitis groups.
    • Bile from patients with chronic cholecystitis was more concentrated compared to those with acute cholecystitis.
    • Protein content showed wide variation within both acute and chronic cholecystitis patient groups.

    Conclusions:

    • Proton magnetic resonance (MR) T1 and T2 relaxation times are not reliable biomarkers for distinguishing acute from chronic cholecystitis.
    • Bile concentration may offer some distinction, but protein content is highly variable.
