22.2 Results
Table 22.1 shows the results of the measurements. The median radiation exposure dose to the operator physicians was low at 12 μSv per exam. The radiation exposure dose to the other medical staff, such as nurses and radiology technicians, was almost negligible low, probably because they stood farther away from the operating table. Logistic regression analysis indicated that increased body mass index (BMI) of the participants and displacement of the radial EBUS (R-EBUS) probe from a lesion were the risk factors for increases in radiation exposure dose [1].

Radiation exposure dose from fluoroscopy during bronchoscopy
Median (range) | P value (vs. operator physician) | |
|---|---|---|
Duration of fluoroscopy (min) | 7.6 (1.5–23.9) | |
Operator physician (μSv/exam) | 12 (1–99) | |
Assistant physician (μSv/exam) | 3 (0–7) | <0.01 |
Nurse (μSv/exam) | 0 (0–9) | <0.01 |
Radiology technician (μSv/exam) | 0 (0–1) | <0.01 |
