    Summary

    CT-guided liver biopsies using the Menghini needle achieved an 86% diagnostic tissue recovery rate. This method offers superior accuracy and specimen yield compared to blind or ultrasound-guided techniques for focal liver lesions.

    Area of Science:

    • Hepatobiliary Medicine
    • Interventional Radiology
    • Diagnostic Pathology

    Background:

    • Liver biopsies are crucial for diagnosing focal liver lesions.
    • Traditional blind liver biopsy techniques have limitations in accuracy and specimen adequacy.
    • Ultrasound-guided biopsy offers visualization but may yield smaller tissue samples.

    Purpose of the Study:

    • To evaluate the efficacy of CT-guided liver biopsy using the Menghini needle.
    • To compare CT-guided biopsy with blind and ultrasound-guided techniques.
    • To determine the diagnostic yield for focal liver lesions.

    Main Methods:

    • CT-guided liver biopsies were performed on 42 patients using the Menghini needle.
    • The Menghini needle is a specific type of biopsy needle designed for liver tissue acquisition.
    • Diagnostic tissue recovery rates were assessed for focal liver lesions.

    Main Results:

    • Successful recovery of diagnostic tissue was achieved in 86% of focal liver lesions.
    • CT-guided biopsy demonstrated better diagnostic specimen recovery than blind techniques.
    • Greater tissue amount and improved guidance accuracy were observed compared to ultrasound-guided methods.

    Conclusions:

    • CT-guided liver biopsy with the Menghini needle is an effective method for obtaining diagnostic histologic specimens.
    • This technique is particularly indicated for patients with few focal liver defects requiring histological analysis.
    • It offers advantages in accuracy and tissue yield over alternative biopsy approaches.
