Suspicious features include increased wall thickness (>3 mm), increased signal intensity on T2-weighted images (Fig. 11b) and progressive enhancement of the bile ducts (due to the fibrotic component of the tumour) following intravenous administration of gadolinium.
Increased wall thickness and Al substitution lead to an improved chemical stability against alkaline solution.
TEM images also showed that treated MWCNT filler increased wall thickness of nanotube.
The joint impact of pipeline diameter and wall thickness on failure rate reveals that increased wall thickness is effective in mitigating risks.
Computed tomography (CT) revealed increased wall thickness in the left half of the transverse colon; however, the absence of increased CT values in the surrounding fatty area suggested that its invasion depth was the muscularis propria (MP).
On bedside sonography, no pericardial effusion was noted, aorta size was normal without evidence of mural thrombosis or false lumen, no hydronephrosis or stone was remarked in the right kidney, and gallbladder scan showed increased wall thickness and multiple tiny gallstones with posterior shadows without pericholecystic fluid.
Although the evaluation of vessel wall thickness on CECT may serve as a good predictor of vascular inflammation [9, 31], increased wall thickness can persist for a long time after the acute phase of arterial inflammation, thus limiting its relevance in the early assessment of inflammation.
Overall, there was good agreement between luminal narrowing at CMRA and increased wall thickness at MR-CVW in all patients.
The normalized wall index was higher in asymptomatic subjects when compared to patients (82.8 ± 20.7 versus 68.2 ± 17.0, p = 0.012), representing an increased wall thickness in all patients and asymptomatic subjects but a relatively thicker vessel wall compared to lumen diameter in patients.
