- W2978045205 abstract "Objective: To determine the CT perfusion values of metastastic lymph node tumors, lymphoma and muscle by using multislice computed tomography (MSCT) with body perfusion software package and to assess their differences and correlations. Methods: MSCT perfusion imagings were obtained in patients with metastatic lymph node tumor (n=40), lymphoma (n=22), and in the muscle of healthy volunteers (n=50) by a multisection CT scanner (Siemens Somato Volume Zoom 4) with following parameters: 4×5 mm collimation, 120 kV, 60 mA. The data acquisition lasted for 40 seconds after 40 ml nonionic contrast agent (I 300 mg /ml, 4.0 ml/s) was administered by a power injector with a 5 seconds delay. The mean blood flow (BF) was measured on an MV 300 workstation using body perfusion software (Siemens) by deconvolution method. Results: The mean values of BF in normal muscle, metastatic lymph node tumor and lymphoma were (0.20±0.08)ml/(min·ml), (0.50±0.16) ml/(min·ml), and (0.71±0.18)ml/(min·ml), respectively, with those in metastatic lymph node tumor and lymphoma significantly higher than those in normal muscle (P 0.001) and that in lymphoma significantly higher than that in metastatic lymph nodes (P0.05). Conclusion: MSCT perfusion imaging has clinical value in differentiating cervical malignant lymph node lesions." @default.
