  • Efficacy Evaluation of SAVE for the Diagnosis of Superficial Neoplastic Lesion
    Efficacy Evaluation of SAVE for the Diagnosis of Superficial Neoplastic Lesion

    The detection of non-polypoid superficial neoplastic lesions using current standard of white light endoscopy surveillance and random biopsy is associated with high miss rate. The subtle changes in mucosa caused by the flat and depressed neoplasms often go undetected and do not qualify for further investigation, e.g., biopsy and resection, thus increasing the risk of cancer advancement. This paper presents a screening tool named the saliency-aided visual enhancement (SAVE) method, with an objective of highlighting abnormalities in endoscopic images to detect early lesions.
