METHODS： This retrospective study evaluated 65 cases of GBCA that were categorized morphologically into the intraluminaI-GBCA （n = 37） and infiltrating-GBCA （n = 28） groups. The clinical and laboratory findings, presence of gallstones, gallbladder size, T-staging, nodal status, sensitivity of preoperative US and CT studies, and outcome were compared between the two groups. RESULTS： There were no significant differences between the two groups with respect to female predominance, presence of abdominal pain, serum aminotransferases level, T2-T4 staging, and regional metastatic nodes. Compared with the patients with intraluminaI-GBCA, those with infiltrating-GBCA were significantly older （65.49 ± 1.51 years vs 73.07 ± 1.90 years）, had a higher frequency of jaundice （3/37 patients vs 13/28 patients） and fever （3/37 patients vs 10/28 patients）, higher alkaline phosphatase （119.36 ± 87.80 IU/L vs 220.68 ± 164.84 IU/L） and total bilirubin （1.74 ± 2.87 mg/L vs 3.50 ± 3.51 mg/L） levels, higher frequency of gallstones （12/37 patients vs 22/28 patients）, smaller gallbladder size （length, 7.47± 1.70 cm vs 6.47 ± 1.83 cm; width, 4.21 ± 1.43 cm vs 2.67 ± 0.93 cm）, and greater proportion of patients with 〈 12 mo survival （16/37 patients vs 18/28 patients）. The sensitivity for diagnosing intraluminal- GBCA with and without gallstones was 63.6% and 91.3% by US, and 80% and 100% by CT, respectively. The sensitivity for diagnosing infiltrating-GBCA with and without gallstones was 12.5% and 25% by US, and 71.4% and 75% by c-r, respectively. CONCLUSION： In elderly women exhibiting small gallbladder and gallstones on US, especially those with jaundice, fever, high alkaline phosphatase and bilirubin levels, CT may reveal concurrent infiltrating-GBCA.展开更多

METHODS: Inner-Field-of-View DTI data previously acquired from ten pediatric healthy subjects(mean age = 12.10 years) was used to assess for reliability. ROIs were drawn by two neuroradiologists on each subject data twice within a 3-mo interval. ROIs were placed on axial B0 maps along the cervical spine using free-hand and fixed-size ROIs. Agreement analyses for fractional anisotropy(FA), axial diffusivity, radial diffusivity and mean diffusivity were performed using intra-class-correlation(ICC) and Cronbach's alpha statistical methods.RESULTS: Inter- and intra-rater agreement between the two ROI methods showed moderate(ICC = 0.5) to strong(ICC = 0.84). There were significant differences between raters in the number of pixels selected using free-hand ROIs(P < 0.05). However, no significant differences were observed in DTI parameter values. FA showed highest variability in ICC values(0.10-0.87). Cronbach's alpha showed moderate-high values for raters and ROI methods. CONCLUSION: The study showed that high reproducibility in spinal cord DTI can be achieved, and demonstrated the importance of setting detailed methodology for post-processing DTI data, specifically the placement of ROIs.展开更多
