Liver-spleen scintigraphy is a highly effective screening tool for diagnosing chronic liver disease before liver biopsy, significantly outperforming ultrasonography. This imaging method is frequently used in patients over 50.

Area of Science:

  • Hepatology
  • Diagnostic Imaging
  • Radiology

Background:

  • Percutaneous liver biopsy is a key diagnostic procedure for suspected chronic liver disease.
  • Hepatic imaging plays a role in patient evaluation prior to biopsy.

Purpose of the Study:

  • To analyze the utilization and diagnostic yield of hepatic imaging modalities in patients referred for percutaneous liver biopsy.
  • To compare the effectiveness of liver-spleen scintigraphy, ultrasonography, and computed tomography in detecting diffuse liver disease.

Main Methods:

  • Prospective analysis of 91 patients undergoing percutaneous liver biopsy for suspected chronic liver disease.
  • Review of hepatic imaging procedures performed, including liver-spleen scintigraphy, ultrasonography, and computed tomography.
  • Comparison of imaging findings with biopsy results and analysis of factors influencing imaging frequency.

Main Results:

  • Hepatic imaging was performed in 56% of patients; liver-spleen scintigraphy was the predominant modality (82% of imaging cases).
  • Scintigraphy demonstrated diffuse liver disease in 95% of cases, while ultrasonography showed none (P < 0.0001).
  • Imaging frequency was significantly higher in patients over 50 years old (76% vs. 37%, P < 0.001).

Conclusions:

  • Liver-spleen scintigraphy is a sensitive and frequently utilized screening tool for diffuse liver disease prior to percutaneous liver biopsy.
  • The use of scintigraphy is justified by diagnostic accuracy and other factors beyond initial diagnosis, particularly in older patients.
