Initial phantom study on estimation of speed of sound in medium using coherence among received echo signals

ConclusionThe speed of sound of a homogeneous medium could be determined by the proposed method with errors of less than 1% using CFs obtained from ultrasonic echo signals selected based on the CF-weighted echo amplitudes, i.e., when echo signals with better signal-to-noise ratios (SNRs) were used.

This study aims to assess whether ultrasound-guided injection of platelet-rich plasma can safely and effectively treat symptoms associated with acetabular hip labral tears. Design Institutional review board approval was gained for a prospective study of eight patients (N = 8), who have previously failed conservative management, to receive ultrasound-guided injection of platelet-rich plasma at the site of hip labrum tear. We assessed pain reduction and functional ability at baseline and then 2, 6, and 8 wks after injection, using the visual analog scale and Harris Hip Score, respectively. Results Statistically signifi...

Introduction Ozone has been recently used as a safe alternative treatment in musculoskeletal disorders with fewer adverse effects than corticosteroids. The aim of this study was to compare the efficacy of a single injection of ozone with that of a corticosteroid in the treatment of shoulder impingement. Design Thirty patients with shoulder pain and clinical signs and symptoms of impingement were randomly assigned into two groups: ultrasound-guided injection with ozone or corticosteroid. Patients’ symptoms were evaluated by visual analog scale, constant score, shoulder pain and disability scale, shoulder range of...

We describe a case of posttraumatic chronic intercostal neuralgia, in which successful pain relief was achieved via repeated injections of local anesthetic and steroid combinations in the serratus anterior plane under ultrasonographic guidance. This novel technique is easy to administer, reliable, and warrants further investigation with regard to its use for rehabilitation of patients who are experiencing posttraumatic chronic neuropathies of the chest wall.

Authors: De Luca S, Fiori C, Bollito E, Garrou D, Aimar R, Cattaneo G, De Cillis S, Manfredi M, Tota D, Massa F, Passera R, Porpiglia F Abstract BACKGROUND: To evaluate if multiparametric magnetic resonance (mpMRI)- transrectal ultrasound (TRUS) fusion targeted biopsy (TBx) versus untargeted standard biopsy (SBx) may decrease the rate of pathological upgrading of Gleason score (GS) 3+4 prostate cancer (PCa) at radical prostatectomy (RP). We also evaluated the impact of percent pattern 4 and cribriform glands at biopsy in the risk of GS 3 + 4 = 7 upgrading. METHODS: 301 patients with GS 3+4 PCa on biopsy (159 SB...
