EUS-guided fine needle biopsy: minimally invasive access to metastatic or recurrent cancer

High Performance Relaxor-Based Ferroelectric Single Crystals for Ultrasonic Transducer Applications

“…Compared with traditional ultrasound, EUS imaging is more accurate, and gives more detailed information due to the proximity of the EUS transducer to the organs of interest. This methodology proves to be effective, safe, minimally-invasive, and very well tolerated, which has been investigated by numerous studies [53,61–63]. However, the currently used endoscopic-type ultrasonic transducers are mainly made from piezoelectric PZT ceramics, whose properties are not as good as those of PMN-PT single crystals.…”

Diagnosis of recurrent lung cancer in the mediastinum using endosonographically guided fine‐needle aspiration biopsy

“…10,11 Our case illustrates that after surgery and adjuvant radiation therapy for lung cancer, EUS-FNA can be performed safely and obviates the need for thoracotomies. Whether this changes patient survival is unclear.…”

Linear and curved‐linear (convex) endoscopic ultrasonography: The present situation and roles in the future

“…Furthermore, immunostaining and genetic analysis may be applied to histology samples. Thus, with the case of local recurrence, mainly developed at the outside of the intestintal tract after surgery, 13 EUS‐FNAB can become a useful diagnostic method for cases where biopsy with direct observation is impossible.…”
