Dynamic liver scanning in cirrhosis.

M I McLaren, J S Fleming, B H Walmsley

    Summary

    Dynamic liver scanning with 99mTc sulphur colloid reveals reduced mesenteric fraction (MF) and liver:spleen ratio (L:S) in cirrhosis patients. These scintigraphy findings may aid in monitoring disease progression and treatment response.

    Area of Science:

    • Nuclear Medicine
    • Hepatology
    • Radiology

    Background:

    • Cirrhosis is a severe liver condition with significant morbidity.
    • Assessing disease severity and monitoring treatment response in cirrhosis remains challenging.
    • Dynamic liver scintigraphy offers a non-invasive imaging approach.

    Purpose of the Study:

    • To evaluate the utility of dynamic liver scanning using 99mTc sulphur colloid in patients with cirrhosis.
    • To compare scintigraphic parameters between cirrhotic patients and healthy controls.
    • To explore the correlation between scintigraphic findings and clinical outcomes, such as variceal bleeding.

    Main Methods:

    • Dynamic liver scintigraphy was performed on 41 patients with cirrhosis and 33 control subjects.
    • Technetium-99m sulphur colloid (99mTc SC) was used as the radiotracer.

  • Key parameters analyzed included the mesenteric fraction (MF) and the liver:spleen ratio (L:S).

    • Main Results:

    • Cirrhotic patients exhibited a significantly reduced mesenteric fraction (MF) (0.30 +/- 0.17) compared to controls (0.58 +/- 0.09) (P < 0.001).
    • The liver:spleen ratio (L:S) was also significantly lower in cirrhotics (1.6 +/- 0.95) versus controls (4.9 +/- 1.4) (P < 0.001).
    • Patients with a history of recent variceal bleeding showed lower MF and L:S values than those without bleeding.

    Conclusions:

    • Dynamic liver scintigraphy using 99mTc SC can effectively differentiate cirrhotic patients from controls.
    • Reduced MF and L:S ratios are indicative of cirrhosis.
    • This imaging technique shows potential for monitoring disease progression and evaluating treatment efficacy in cirrhosis.
