“…In previous studies, the visibility of needles was scored based on grading of observers [ 4 , 5 ]. Visual perception of the needle tips on US images depends on multiple factors, such as tissue echogenic properties, formation of artifacts, equipment quality.…”

“…Several techniques have been reported in the literature to improve the visibility of needles in 2D ultrasound image guidance. Kawai et al [ 4 ] used a commercially available vascular needle (20 gauge) and created four modified versions: a re-cut needle, a dimple needle, a file-like rough surface needle and a needle with four sides holes. They evaluated the 2D US images, and the visibility was graded from invisible to excellent by interventional radiologists.…”

AimNeedle visibility is crucial for effective and safe ultrasound-guided interventional procedures. Several studies have investigated needle visibility in 2D ultrasound imaging, but less information is available for 3D ultrasound imaging, a modality that has great potential for image guidance interventions. We performed a prospective study, to quantitatively compare the echogenicity of various commercially available needles in 3D ultrasound images used in clinical practice under freehand needle introduction.Materials and MethodsA set of seven needles, containing biopsy needles, a TIPS needle, an ablation needle and a puncture needle, were included in the study. A liver-mimicking phantom and cow liver were punctured by each needle. 3D sweeps and real-time 3D data were acquired at three different angles (20°, 55° and 90°). Needle visibility was quantified by calculating contrast-to-noise ratio.ResultsIn the liver-mimicking phantom, all needles showed better visibility than in the cow liver. At large angles, contrast-to-noise ratio and needle visibility were almost similar in both cases, but at lower angles differences in visibility were observed with different types of needles.ConclusionThe contrast-to-noise ratio increased with the increase in angle of insonation. The difference in visibility of different needles is more pronounced at 20° angle. The echogenic properties of inhomogeneous cow liver tissues make the needles visibility worse as compared to a homogenous phantom. The needle visibility becomes worse in 3D real-time data as compared to 3D ultrasound sweeps.

“…Various factors may influence needle visibility. Numerous studies describe the influence of needle insertion angle and different needle types on needle visibility in B-mode [2][3][4][5]. However, these studies mostly examined qualitative assessment based on a visual rating system.…”
