Red depicts soft areas, and blue depicts hard areas relative to the entire elastography image. The Bosniak classification is divided into four groups going from I, corresponding to a simple cyst, to IV, corresponding to a cyst with solid parts and an 85%100% risk of malignancy [13,16]. The kidney is divided into parenchyma and renal sinus. Urea is carried in the bloodstream to the kidneys. Therefore, renal tumors without a Doppler signal, which are not obvious simple cysts on US and CT, should be further investigated with CEUS, as CEUS is more sensitive than both Doppler US and CT for the detection of hypovascular tumors [20]. The importance of segmentation in medical applications is inevitable and hence its performance and accuracy is a priority. 2. appointment. the ultrasound wave will be sent through that patient's body.
