Endobronchial ultrasound-guided sampling using transbronchial needle aspiration plays a key role in staging and diagnosing lung cancer. We propose a systematic stepwise approach dividing the procedure into six landmarks that should be taught to new operators.

Using the Endoscope for Endobronchial Ultrasound in the Esophagus

Transesophageal ultrasound (EUS-B) is a safe and feasible procedure using the echoendobronchoscope (EBUS) in esophagus and stomach. After identifying six anatomical landmarks, additional structures can be identified and biopsied, sparing subsequent diagnostic sessions. Thus, EUS-B is an ideal continuation of bronchoscopy and EBUS in diagnosing lung cancer and other diseases.

Substernal thyroid lesions are common, and need to be differentiated from malignancy. Obtaining percutaneous fine needle biopsy is not possible due to its retrosternal location. This article proposes a protocol for biopsy of substernal thyroid lesions using Endobronchial Ultrasound-guided Transbronchial Needle Aspiration (EBUS-TBNA).

We describe a new ultrasound-based vector tissue Doppler imaging technique to measure muscle contraction velocity, strain and strain rate with sub-millisecond temporal resolution during dynamic activities. This approach provides complementary measurements of dynamic muscle function and could lead to a better understanding of mechanisms underlying musculoskeletal disorders.
FAQs
The transducer emits high-frequency sound waves, then receives echoes returning from nearby tissues. Differences in these echoes generate real-time images of structures surrounding the airway, including mediastinal and hilar lymph nodes. This imaging perspective allows clinicians to locate relevant targets that cannot be assessed by viewing the airway surface alone.
Real-time imaging helps align the integrated needle with a selected target before tissue is collected through the airway wall. This links the sampling step to the visualized structure rather than relying only on airway anatomy. The combination can improve diagnostic precision when evaluating lymph nodes or other abnormalities surrounding the airways.
Endobronchial Ultrasound combines visualization and tissue sampling during bronchoscopy, providing a minimally invasive alternative to approaches that require more extensive surgery. Its value is not limited to producing images: the integrated needle can obtain tissue during the same examination. This may reduce the need for invasive surgical procedures in appropriate diagnostic evaluations.
The procedure places a flexible bronchoscope with a small ultrasound transducer at its tip into the airways. The transducer produces real-time images of surrounding structures, particularly mediastinal and hilar lymph nodes. When a relevant target is identified, an integrated needle passes through the airway wall to collect tissue for evaluation.
Clinicians use Endobronchial Ultrasound to support the diagnosis and staging of lung cancer, especially when mediastinal or hilar lymph nodes require assessment. The technique also helps investigate enlarged lymph nodes and evaluate possible infections or inflammatory disease. Its ability to image and sample in one procedure supports several related diagnostic questions.
Ultrasound images show the location and appearance of structures surrounding the airway, while tissue obtained through the integrated needle provides material for diagnostic evaluation. This pairing can strengthen interpretation when imaging alone cannot establish the cause of an abnormality. In medicine, the combined information supports evaluation of cancer, infection, and inflammatory disease.
