Accuracy of Prostate Volume Measurement on 2d Transabdominal USG Modality Using the Gradient Vector Flow (GVF) Segmentation Application Measurement Technique

Abstract

In the field of radiology, supporting examinations to evaluate the prostate include examination with X-rays, Magnetic Resonance Imaging (MRI), and ultrasonography (USG). Of all imaging examinations that have been carried out throughout the world, it is estimated that around 25% use ultrasound. The general objective of this research is to analyze the design of the Gradient Vector Flow (GVF) segmentation algorithm on 2D ultrasound images to measure prostate volume in the adult age group. This study created a Gradient Vector Flow (GVF) segmentation application for the prostate organ to calculate the prostate volume calculation. RnD research with an experimental approach was carried out by creating a Gradient Vector Flow (GVF) segmentation design application, tested on 15 DICOM-based ultrasound images, measuring and calculating prostate volume using caliper measurement on ultrasound equipment and Gradient Vector Flow segmentation application. Measurements were made by an expert (sonographer) as an observer with data analysis using SPSS statistics. Analysis of ultrasound image of prostate volume using caliper measurement technique and Gradient Vector Flow (GVF) segmentation is similar to a p-value of 0.950 (> 0.05). Measurement with caliper measurements has similarities shown by the mean rank value of Gradient Vector Flow (GVF) of 15.60 with a mean rank value of caliper measurement of 15.40. GVF application measurement on transabdominal ultrasound prostate volume measurement is similar to caliper measurement and can be used to get more accurate results on objects with less clear edge characteristics. However, the caliper measurement method can be used more efficiently.
