图1 1例胰腺导管腺癌患者的术前BMUS影像及SWE定量评估 Note： A. The body part of pancreatic parenchyma (red arrows) in the superficial layer of portal vein was clearly displayed on BMUS with a lesion located in the body-tail part of pancreas (yellow cursors). B. VTIQ assessment makes the visualization of relative elasticity of target tissues. The body part of pancreatic parenchyma appeared in an evenly blue color, which indicated a relatively low elasticity. C. VTIQ revealed an unevenly green color in the pancreatic lesion, which indicated a relatively high elasticity. The circles in B and C indicate the ROIs in the pancreatic parenchyma and the lesions, respectively, and the SWV values were detected. AA—abdominal aorta; IVC—inferior vena cava; PL—pancreatic lesion; PV—portal vein.
