Lumbar punctures (LPs) are interventional procedures that are used to collect cerebrospinal fluid. Since the target window is small, physicians have limited success conducting the procedure. The procedure is especially difficult for obese patients due to the increased distance between bone and skin surface. We propose a simple and direct needle insertion platform, enabling image formation by sweeping a needle with a single ultrasound element at the tip. The needle-shaped ultrasound transducer can not only sense the distance between the tip and a potential obstacle, such as bone, but also visually locate the structures by combining transducer location tracking and synthetic aperture focusing...

A diagnosis of pulmonary sarcoidosis is based on the assessment of clinical outcome, radiology findings and detection of noncaseating granulomas in cytology or histology specimens. Cytological material obtained from enlarged lymph nodes and/or histological specimens from bronchial mucosa and lung tissue are examined according to sarcoidosis stage. The most available are standard bronchoscopic methods as conventional transbronchial needle aspiration (cTBNA), endobronchial biopsy (EBB) and transbronchial lung biopsy (TBLB) both performed with use of forceps...

Over the last few decades, fine needle aspiration cytology (FNA) has emerged as a SAFE (Simple, Accurate, Fast, Economical) diagnostic tool based on the morphologic evaluation of cells. The first and most important step in obtaining accurate results from FNA is to procure sufficient and representative material from the lesion and to appropriately transfer this material to the laboratory. Unfortunately, the most important aspect of this task occurs beyond the control of the cytopathologist, a key reason for obtaining unsatisfactory results with FNA...

PURPOSE: To describe a single skin puncture technique combining subcutaneous injection of anesthetic to the depth of the vessel wall with venipuncture in the same movement. TECHNIQUE: Using ultrasound guidance, controlled anesthetic instillation along the needle tract and outer vessel wall with a 21-G vascular access needle can be combined with vessel puncture. This technique reduces the number of skin punctures and ensures accurate anesthetic instillation. The maximum inadvertent intravascular dose of commercial local anesthetic preparations that can be delivered with a small syringe is far below toxicity thresholds...
