| 目的 初步探讨在PACS (picture archiving and communication system，PACS)工作站评价肺癌强化的效率及有效性。方法 62例周围型肺癌患者经屏气训练后，采用64层螺旋CT（multi-slice spiral computed tomography ，MSCT）行胸部增强双期扫描（以4ml/s的速度注入造影剂），分别在25s及90s行胸部螺旋扫描。在PACS及CT工作站上分别测量肺癌增强前后各时相的CT值并计算强化净增值及记录90s时肺癌的强化模式。 结果 在PACS工作站上测量肺癌平扫CT值（40.21±7.03Hu）、增强后25s（55.53±11.09 Hu）及90s CT值（75.95±13.45 Hu）分别为与在CT工作站上测量（39.01±8.95Hu；56.01±10.91 Hu；76.03±11.95Hu）无显著差异（t=1.140 , p=0.256>0.05；t=1.580 , p=0.149>0.05；t=1.505 ,p=0.150﹥0.05）。在PACS工作站上计算强化净增值（35.74±11.95 Hu）与在CT工作站上（37.02±12.05 Hu）无显著差异（t=2.001 , p=0.099>0.05）。在PACS及CT工作站上观察62例90s时肺癌的强化模式表现相同，其中38例表现为均匀强化；17例表现为不均匀强化, 5例表现为周边强化,2例表现为中央强化。 结论 在PACS工作站与在CT工作站评价肺癌强化的无显著差异，PACS工作站能准确评价肺癌强化。 |

| Objective: The aim of the study was to determine the efficiency and effectiveness of picture archiving and communication system (PACS) workstation in detecting enhancement pattern of peripheral bronchogenic carcinoma. Methods: The 62 patients with peripheral bronchogenic carcinoma underwent two-phase contrast material-enhanced multislices computed tomography (MSCT) of the chest in a single-breath-hold technique. Two spiral CT scans were obtained at 25 s and 90 s respectively after nonionic contrast material was administrated via the antecubital vein at a rate of 4 mL/s by using an autoinjector. Precontrast and postcontrast attenuation on every scan were measured on PACS and CT orkstations respectively and peak height was calculated. Enhancement pattern was evaluated on the image obtained at 90 s after injection of contrast medium on PACS and CT workstations respectively. Results: No statistically significant difference in precontrast attenuation, postcontrast attenuation at 25 s and 90 s was found between these measured on a PACS workstation [(40.21 ± 7.03) HU; (55.53 ± 11.09) HU; (75.95 ± 13.45) HU] and those [(39.01 ± 8.95) HU; (56.01 ± 10.91) HU; (76.03 ± 11.95) HU] on a CT workstation (t = 1.140, P = 0.256 > 0.05; t = 1.580, P = 0.149 > 0.05; t = 1.505, P = 0.150﹥0.05). The peak height that calculated on a PACS workstation was 35.74 HU (20 HU). There was not statistically significant difference in peak height between that calculated on a PACS workstation and that on a CT workstation [(37.02 ± 12.05) HU; t = 2.001, P = 0.099 >
0.05]. The tumors showed same enhancement pattern on PACS workstation and CT workstation. Of the 62 cases, 38 showed homogeneous enhancement, 17 showed heterogeneous enhancement, five showed peripheral enhancement, two showed central enhancement, at 90 s. The enhancement pattern revealed on PACS workstation was consistent with feature of peripheral bronchogenic carcinoma. Conclusion: The efficiency and effectiveness of PACS workstation is as same as those of CT workstation in detecting enhancement pattern of peripheral bronchogenic carcinoma. |
