(a) Imaging features of the stents. CT sag indicates sagittal CT image; CT ax, axial CT image; CM, stent filled with diluted contrast medium. The numbers separated by the slash indicate the window width and window level (in Hounsfield units).
A, 2.0-mm stents.
B, 3.0-mm stents.
C, 4.0-mm stents.
- Fig 2.
Attenuation profile of the BOC3 stent. The difference between two vertical lines represents a distance of 0.5 mm.
A, BOC3 filled with only NaCl solution only. PNHU<200(NaCl) = 3.
B, BOC3 filled with diluted contrast medium. PNHU<200(CM) = 0.
- Fig 3.
ALN of the stents and tubes when filled with diluted contrast medium. ALN1500/400 was 0% for T3, and ALN500/200 was 0% for T4.
- Fig 4.
DIFFHU<200 of the stents. DIFFHU<200 was zero for all 2.0-mm stents.
