Efficacy of intraoperative ultrasonography for the detection of small lung nodules
- Conditions
- lung cancer, metastatic lung tumor, benign lung nodule
- Registration Number
- JPRN-UMIN000036921
- Lead Sponsor
- Department of Surgery, Teikyo University School of medicine
- Brief Summary
22 tumors (85%) were detectable with ultrasonography after lung collapse. Of these 22 tumors, 16 were well-depicted, while six were poorly delineated. tumor dimension of the mediastinal window (MD) showed the largest area under the receiver operating characteristic curve (0.81), and tumors with an MD less than 6 mm had a high risk of difficult localization using ultrasonography.
