Needle placement under ultrasound can be achieved by two different approaches, namely, an In-plane and Out-of-plane technique. Each of these approaches offers its own advantages and challenges. Depending on different factors that include body habitus, anatomic considerations, and needle trajectories ...
The aim of this study was to assess the out-of-plane versus the in-plane approaches for the interscalene brachial plexus block, as regards the performance time, the onset, the progression and the recovery of sensory block, the onset and progression of the motor block as well as, the postop...
BackgroundA long-axis in-plane (LA-IP) approach and a short-axis out-of-plane (SA-OOP) approach are the two main approaches used in ultrasound (US)-guided vascular catheterization. However, the efficacy and safety of these approaches remain controversial. Therefore, we performed this meta-ana...

In freehand 3D ultrasound (US), the relative positions and orientations of the 2D US images are usually obtained from a position tracking device, at the expense of clinical convenience. As an alternative or complement to this approach, transducer motion can be inferred from image content, using...
Subsequently, the ultrasound probe was moved 2–3 cm laterally to locate the hyperechogenicity of the T8 transverse process and identify the erector spinae muscle. Using an in-plane technique, a 21-G needle was advanced in a cranio-caudal direction until the tip of the needle reached the ...
The transgastric two-chamber view is developed from the same probe position by rotating the multiplane angle forward to about 90 degrees and is especially useful for examining the chordae tendinae, which are perpendicular to the ultrasound beam in this view. The chordae to the posteromedial ...
Ultrasound-based local pulse wave velocity (PWV) estimation, as a measure of arterial stiffness, can be based on fast focused imaging (FFI) or plane wave imaging (PWI). This study was aimed at comparing the accuracy of in vivo PWV estimation using FFI and PWI. Ultrasound radiofrequency data...
Different techniques can be used to inject a fascial plane, e.g., in-plane technique vs. out-of-plane technique. The in-plane needling has the significant advantage of allowing the needle to be seen along its entire length, including its tip. This way, the direction of the puncture can...
They were randomized to out-of-plane (Group I, n = 43) and in-plane (Group II, n = 43) groups. In group I, the number of first-attempt cannulations was very high (p Conclusions Out-of-plane ultrasound imaging during axillary vein cannulation increased the chance of first-attempt ...
