Defining New Metrics in Microwave Ablation of Pulmonary Tumors: Ablation Work and Ablation Resistance Score.

摘要: Abstract Purpose To investigate pulmonary microwave ablation metrics including work, resistance score, and involution. Materials Methods Retrospective review was performed of 98 tumor ablations using the NeuWave Certus Microwave Ablation System (NeuWave Medical, Madison, Wisconsin) in 71 patients (32 men 39 women; mean age, 64.7 y ± 11.5). work defined as sum (power) * (time) (number antennas) for all phases during an procedure. zone measured on CT at 3 time points: after procedure, 1–3 months (mean 47 d), 3–12 292 d). zones were scored based location lobe (upper = 1, middle/lingula 2, lower=3) region (peripheral parenchymal=2, central=3), 2 summed score. Results significantly smaller regions with higher score ( P Conclusions Pulmonary is correlates to a nonlinear involution pattern first year may be useful planning before
