    Post-data processing (PDP) can improve visualization of subtle hepatic metastases on ultrasound, but does not reveal new lesions. Fundamental equipment improvements are needed for enhanced hepatic sonography sensitivity.

    Area of Science:

    • Medical Imaging
    • Diagnostic Ultrasound
    • Hepatology

    Background:

    • Digital equipment enables sonographic image manipulation, termed pre-data or post-data processing (PDP).
    • PDP alters the gray scale curve to enhance specific decibel ranges for improved image interpretation.

    Purpose of the Study:

    • To evaluate the effectiveness of post-data processing (PDP) in visualizing hepatic metastases on sonograms.
    • To determine if PDP can identify lesions not visible with standard linear gray scale imaging.

    Main Methods:

    • Sixty patients with technically adequate hepatic sonograms were analyzed.
    • Scans were initially assessed using the normal linear gray scale range and then with PDP.
    • Abnormal scans were categorized based on echogenic differences between lesions and liver tissue.

    Main Results:

    • Of 60 patients, 32 had normal sonograms and 28 had abnormal findings.
    • PDP improved visualization of hepatic metastases in 10 of 28 abnormal scans, particularly when echogenic differences were minimal (one false-positive).
    • PDP did not reveal any lesions that were not already recognizable on the standard scan; 18 abnormal scans showed sufficient echogenic difference without PDP's aid.

    Conclusions:

    • Post-data processing can aid in visualizing subtle hepatic metastases but does not increase the detection rate of new lesions.
    • The utility of PDP is limited in cases with significant echogenic differences between lesions and liver.
    • Significant improvements in hepatic sonographic sensitivity necessitate fundamental advancements in equipment technology beyond current PDP capabilities.
