Virtual fluoroscopy during transbronchial biopsy for locating ground-glass nodules not visible on X-ray fluoroscopy

Abstract: Background: Virtual fluoroscopy (VF) is a novel guided technique that provides ray summation images of target lesions similar to X-ray fluoroscopy. Endobronchial ultrasound with a guide sheath (EBUS-GS) is a useful modality for imaging ground-glass nodules (GGNs) but is not ideal for GGNs that cannot be detected on X-ray fluoroscopy. We evaluated whether the addition of VF to EBUS-GS improved the diagnostic yield.Methods: Consecutive patients who had undergone diagnostic bronchoscopy for GGNs that were not det… Show more

“…A 2.4-mm cryoprobe was used with the thick scope after removing the GS. Virtual bronchoscopy (VB) and virtual fluoroscopy (Ziostation2®, Ziosoft Ltd., Tokyo, Japan) were created using thin-section CT (TSCT) images [ 19 , 20 ]. The type of bronchoscope and the size of cryoprobe were selected by each operator based on CT images and VB navigation.…”

“…Finally, the sampling location was adjusted, and radiograph and virtual fluoroscopy images were aligned in up to three directions. 31 Immediately prior to freezing, the auxiliary scope for hemostasis was replaced with a light source from the main scope. Then, the tip of the cryoprobe was frozen for 5 to 6 s, to approximately À42 C, and frozen tissues were retracted using the main scope.…”

“…These virtual images were constructed from highresolution computed tomographic images using a workstation (Ziostation2®, Ziosoft, Tokyo, Japan) before the procedure. 9,27 We divided the R-EBUS ndings into three groups, "within," "adjacent to," and "invisible," according to the positional relationship between the probe and the target. 3 If the lesion could not be detected using R-EBUS, the lesion was considered invisible and excluded from the analysis.…”
