Segnet Network Algorithm-Based Ultrasound Images in the Diagnosis of Gallbladder Stones Complicated with Gallbladder Carcinoma and the Relationship between P16 Expression with Gallbladder Carcinoma

Figure 9

Contrast-enhanced ultrasound examination. (a) The patient was a 62-year-old male with a history of gallbladder stones for 5 years and epigastric pain for 5 days. Contrast-enhanced ultrasound examination of the abdomen showed that the continuity of the gallbladder wall was locally interrupted, and a slightly strong echogenic nodule protruding into the cavity was seen near the bottom. (b) The patient was a 55-year-old female with dull pain in the upper abdomen for half a year. Contrast-enhanced ultrasound examination of the abdomen showed the thickening of the gallbladder wall, and a moderate echogenic mass filled the cyst cavity at the bottom of the gallbladder. (c) The patient was a 53-year-old female with abdominal pain for 3 days. Contrast-enhanced ultrasound examination of the abdomen showed that the gallbladder volume increased significantly, and a solid mass with irregular shape was seen in the cyst cavity. (d) The patient was a 64-year-old female with a history of gallbladder stones for 5 years and epigastric pain for 5 days. Contrast-enhanced ultrasound examination of the abdomen showed clear boundaries of gallbladder lesions and irregular thickening of the cyst wall.
