Multi-slice computed tomography for diagnosis of mucinous cystic neoplasms and serous cystadenomas of the pancreas / 南方医科大学学报

<p><b>OBJECTIVE</b>To assess the value of multi-slice computed tomography (MSCT) in the diagnosis and differential diagnosis of pancreatic mucinous cystic neoplasms and serous cystadenoma.</p><p><b>METHOD</b>The MSCT images were reviewed for 19 pathologically confirmed cases of pancreatic mucinous cystadenomas and 13 cases of pancreatic serous cystadenomas (n=13) treated in our center between July, 2003 and December, 2009. The CT features were analyzed including the tumor location, contour, dimension of the largest cyst, cystic wall, septation, presence of calcification, solid component, pancreatic atrophy, main pancreatic duct dilatation, and lesion margins.</p><p><b>RESULTS</b>Significant differences were found between the two groups in lesion diameter (P=0.009), cyst distribution of the largest cyst (>2 cm) (P=0.01), and the presence of solid component (P=0.02).</p><p><b>CONCLUSION</b>MSCT can be of important value in the diagnosis and differential diagnosis of pancreatic mucinous cystic neoplasms and serous cystadenomas.</p>

Study on vertebral degenerations of coal miners with low back pain by means of computerized tomography / 中华劳动卫生职业病杂志

<p><b>OBJECTIVE</b>To study lumbar vertebral degenerations of coal miners with low back pain.</p><p><b>METHODS</b>40 underground miners with low back pain, aged from 30 to 50 years and employed for a length from 10 to 30 years, were taken as observation group. 30 ground workers without low back pain but with almost the same age, employment length and height etc. were selected as control group. Intervertebral discs at L3/L4, L4/L5, L5/S1 were scanned with computerized tomography, comparing herniated discs, sagittal diameter of vertebral canal, height of lateral recess, vertebral hypertostosis, ligament hypertrophy and calcification between two groups.</p><p><b>RESULTS</b>L3/L4, L4/L5, L5/S1 herniated discs and narrow lateral recess in observation group(0.33 +/- 0.15, 0.53 +/- 0.25, 0.45 +/- 0.18 and 0.40 +/- 0.08, 0.31 +/- 0.05, 0.37 +/- 0.07) were more serious than that in control group(0.28 +/- 0.11, 0.32 +/- 0.21, 0.37 +/- 0.19 and 0.42 +/- 0.10, 0.43 +/- 0.07, 0.40 +/- 0.06), but only with significant difference at L4/L5 (P < 0.01). Sagittal diameter of vertebral canal in observation group is narrower than that in control group but of little significance(P > 0.05). Cases of vertebral hyperostosis, ligament hypertrophy and calcification were found more frequent in observation group(45.00%, 42.50%, 22.50%) than in control group(23.33%, 16.67%, 16.67%), but only ligament hypertrophy was remarkable(P < 0.05).</p><p><b>CONCLUSIONS</b>As compared with control group lumbar vertebral degenerations are more serious in underground miners with manifestations like herniated disc and narrow lateral recess mainly at L4/L5.</p>
