dc.description.abstractI evaluated the diagnostic accuracy and safety of performing of transthoracic needle biopsy (TNB) using a C-arm cone-beam computed tomography (CBCT) system. I retrospectively evaluated 99 TNB cases performed in 98 patients using a C-arm CBCT system with an 18-gauge automated cutting needle. I reviewed the diagnostic accuracy according to the size and depth of the lesion, incidence of complications, additional treatment for complications, procedure time, number of needle passes per biopsy, and radiation dose. The final diagnoses revealed 72 malignant and 27 benign lesions. The overall sensitivity, specificity, and diagnostic accuracy for the malignancy were 95.8%, 100%, and 97.0%, respectively, and those for small pulmonary nodules less than 20 mm in size were 94.1%, 100%, and 96.6%, respectively. There was no significant difference in the correct diagnosis of malignancy according to lesion size (p = 0.634) or depth (p = 0.542). For benign lesions, a specific diagnosis was obtained in 14 cases (51.9%). TNB induced complications in 19 of 99 procedures (19.2%), including pneumothorax (16.2%), immediate hemoptysis (2.0%), and subcutaneous emphysema (1.0%). Among these, four patients with pneumothorax required chest tube insertion (2.0%) or pig-tail catheter drainage (2.0%). The mean procedure time was 11.9±4.0 min; number of needle passes 1.2±0.5 times; radiation doses 170.0±67.2 mGy, respectively. TNB using a C-arm CBCT system provides high diagnostic accuracy with a relatively low complication rate and a short procedure time, particularly for small pulmonary nodules.;본 연구에서는 C-arm cone beam computed tomography (CBCT) system을 이용하여 시행한 경피적폐침생검의 진단 정확도 및 안전성을 평가하였다. 98명의 환자에서 C-arm CBCT system 유도하에 18 게이지 자동절단침 (automated cutting needle)을 사용하여 경피적폐침생검을 시행한 99증례를 후향적 분석하여 병변의 크기 및 깊이에 따른 진단 정확도, 합병증의 빈도 및 종류, 시술시간, 침 삽입횟수 및 방사선피폭량을 평가하였다. 최종진단은 악성 병변이 72증례, 양성 병변이 27증례로 나타났다. 악성 병변의 민감도, 특이도 및 진단 정확도는 각각 95.8%, 100%, 97.0%로 나타났고, 크기가 20 mm미만의 작은 폐결절의 경우는 각각 94.1%, 100%, 96.6%로 나타났다. 병변의 크기(p = 0.634)와 깊이(p = 0.542)에 따른 악성 병변의 정확한 진단에 유의한 차이점은 없었다. 양성 병변의 경우, 14증례(51.9%)에서 특정 진단명을 얻을 수 있었다. 경피적폐침생검 후 합병증은 19증례(19.2%)에서 보였고, 기흉(16.2%), 즉각적인 객혈(2.0%), 피하기종(1.0%)이 나타났다. 이들 중 4명의 기흉 환자는 가슴관 삽입(2.0%) 또는 pig-tail 카테터 배액 (2.0%)을 시행하였다. 평균시술시간, 침 삽입횟수 및 방사선피폭량은 각각 11.9±4.0 min, 1.2±0.5 times, 170.0±67.2 mGy를 나타냈다. 결론적으로, C-arm CBCT system을 이용한 경피적폐침생검은 특히 작은 폐결절에서 짧은 시술시간과 높은 진단 정확도 및 낮은 합병율을 나타낸다.-
