Abstract:
Objective: To explore the value of small FOV scanning in CT-guided of transthoracic needle lung biopsy (TTLB) for small pulmonary nodule (≤20 mm). Methods: CT-guided TTLB was performed in 104 small pulmonary nodules under CT guidance using small FOV (n=38, group A) or common FOV (n=66, group B) scan mode, respectively. The technique and lesion-related variables, including distance to pleura, times of puncture, operating time and pleura-needle angle, etc. were recorded. The incidence of pulmonary hemorrhage and pneumothorax were compared between 2 groups. Results： The total incidence rate of pulmonary hemorrhage in group A was 31.58% (12/38), of ≥grade 2 pulmonary hemorrhage was 2.63% (1/38), while in group B was 66.67% (44/66) and 22.73% (15/66), respectively. The incidence rate of pulmonary hemorrhage in group A was significantly lower than that in group B (χ2=14.172, P=0.001). There was no significant difference of incidence rate of pneumothorax, distance to pleura, times of puncture nor operating time (all P>0.05). Conclusion： The incidence rate of pulmonary hemorrhage after CT-guided TTLB for small pulmonary nodule (≤20 mm), especially higher-grade (≥grade 2) pulmonary hemorrhage might be significantly reduced by using small FOV scanning mode.
