Real-time grey scale contrast-enhanced ultrasonography in diagnosis of gallbladder cancer

Objective: To explore the clinical value and charateristics of contrast-enhanced ultrasound (CEUS) in diagnosis of gallbladder carcinoma. Materials and methods: 384 patients with benign and malignant gallbladder disease were examined by CEUS. The characteristics of CEUS were analyzed and compared with pathological examination. All the fundamental ultrasound examinations were performed by the Siemens Sequoia Acuson512 or Philips iU22, which were matched with contrast pulse sequence (CPS) imaging technique. Results: (1) The CEUS patterns of Gallbladder carcinomas showed quick and heterogeneous hyper-enhancement at…
