Abstract

This paper describes a study on the automated analysis of ultrasonographic prostate images. With image processing, tissue characterization in the prostate was performed to assess the probability of malignancy. During prostate examinations, images were recorded at the positions where biopsies were taken. The used samples were divided into three groups. Two of them were used for the construction of a classification tree, and the third was used for the evaluation of this classification. A sensitivity of 80.6% and specificity of 77.1% were reached retrospectively. In a prospective way, these results were 80.0% and 88.2%, respectively. The prospective predictive value for cancer detection was 85.7%. The presented prospective value for image analysis was almost twice as high as the values normally found for prostate examination.

    Citation Excerpt :

    Prostate ultrasound images contain high speckle noise, shadow artifacts due to calcification in prostate region, short range of gray levels and boundaries are missing especially at the base and apex region of the prostate [13], which makes the segmentation process difficult. However, ultrasound images are widely used in various computer aided diagnosis (CAD) systems [2,7–11], image guided interventions, and various therapies like brachytherapy. In localized prostate cancer, low-dose-rate (LDR) brachytherapy can be used to provide a quick and accurate diagnosis [14].
