Purpose: To report our experience with computed tomography (CT)-guided coaxial needle biopsy of intrathoracic lesions by different approaches. Material methods: Medical records of 100 patients who underwent CT-guided biopsy of intrathoracic lesions were evaluated retrospectively. A coaxial needle technique was used in all patients; an 18-gauge needle was used for transsternal penetration, throu...

conclusions in squatting position the number of spinal needle-bone contacts was lower compared to the traditional sitting position, nonetheless ease of needle insertion or space identification was the same in the both groups. results the total number of spinal needle bone contact was statistically lower in the squatting position compared to traditional sitting position group (222 versus 230 res...

A new versatile transbronchial needle, the modified type 2B retractable needle, was used for the staging and diagnosis of bronchogenic carcinoma. It combines the advantages of its predecessors, the fixed type 1A needle and the retractable type 2A needle, such as convenience of usage and the added ability to sample peripheral as well as central lesions. The new modified type 2B retractable needl...

Many surgical procedures could benefit from guiding a bevel-tip needle through a sequence of treatment points in a patient. For example, brachytherapy procedures implant radioactive seeds to treat cancer, and biopsy procedures extract tissue samples to test for cancer. A bevel-tip needle has an asymmetric tip that cuts through tissue along a circular arc. By rotating the needle during its inser...

Needle dimensions, needle surface area, needle dry weight per area (LWA) and needle density (ND, needle weight per volume) were measured in terminal current-year shoots in a natural canopy of variably sized Picea abies (L.) Karst. trees growing along a light gradient. Needle shape was described as a rhomboid. Needle width (D(2)) increased with increasing diffuse site factor, a(d) (relative amou...

Lateral transmission of blood-borne diseases can occur when a single needle is used repeatedly to vaccinate livestock. Needle-free technology to vaccinate sheep without damaging the carcass, causing lesions, or leaving needle fragments, and eliciting a similar antibody response as traditional needle vaccinations, has been hampered due to variable wool length. Vaccine delivery, injection time, a...

A new type of needle system combines 2 parts, an inner needle and an outer needle. The inner needle is used for filler injection and the outer needle acts as a guiding needle that can observe blood reflow when inserting into the vessel lumen during injection process. This new needle system can be used for all kinds of filler, providing real time monitoring for physician and preventing intravasc...

Objectives: Dry Needling (DN) is a novel and effective intervention for patients with Myofascial Pain Syndrome (MPS). Some characteristics, such as needle penetration depth, needle insertion into the target muscle, and trigger points must be identified in this intervention. The Ultrasound (US)-guided DN is a technique that involves needle insertion at the site of injury and the simulation of ti...
