A reasoned landmark-based ultrasound scanning technique is described to allow a prompt and reliable identification of these pathologic conditions.
The aim of this study was to evaluate the long-term effects of access to the femoral artery for the purposes of coronary angiography through the measurement of femoral artery distensibility and elasticity on the accessed and non-accessed sides.
This cross-sectional study included patients who underwent femoral angiography at least 1 year previously. Those whose femoral artery was accessed once formed Group 1 (
= 59), those who were accessed twice formed Group 2 (
= 57), those accessed 3 times formed Group 3 (
= 55), and those with more than 3 accesses, Group 4 (
= 60). The groups were compared in respect of femoral artery elasticity and distensibility in the accessed and non-accessed sides.
No statistically significant difference was determined in respect of femoral distensibility and elasticity in Group 1 (9.40 ± 0.84 vs 9.48 ± 0.75,
= 0.107 and 0.23 ± 0.03 vs 0.23 ± 0.03,
= 0.433, respectively). However, a significant difference was observed between the two sides in terms of distensibility and elasticity in Group 2 (9.02 ± 0.81 vs 9.23 ± 0.75, and 0.21 ± 0.02 vs 0.22 ± 0.02), in Group 3 (8.49 ± 0.77 vs 9.18 ± 0.9 and 0.19 ± 0.02 vs 0.21 ± 0.02), and in Group 4 (8.14 ± 0.74 vs 9.03 ± 0.81 and 0.16 ± 0.01 vs 0.2 ± 0.02,
<0.001, for all comparisons).
While a single access in the femoral artery for coronary angiography does not affect femoral artery elasticity and distensibility, multiple accesses may have adverse effects.

The aims of our study were to evaluate cases of extremity pain or swelling in paediatric patients using USG to diagnose acute osteomyelitis, and correlate USG findings with MRI findings.
18 paediatric patients with extremity pain or swelling were evaluated. After the clinical and laboratory work-up, imaging was done using radiographic examination, USG and MRI of the affected limb.
5 patients (27.8%) out of 18 were diagnosed with acute osteomyelitis based on USG findings, confirmed by MRI and surgical drainage. The mean age of the patients with acute osteomyelitis was 8.2 years. Male children were more commonly affected as compared to female. The distal metaphysis of the femur was the most common site involved (80%). The right lower limb was more commonly affected. The most frequent presentation was pain at the affected site. On USG, deep soft tissue fluid collection around the bone was present in all cases (100%). Periosteal thickening or elevation with subperiosteal fluid collection was seen in 4 casesng tool.
Percutaneous ultrasound-guided core needle biopsy is a well-established method in the diagnosis of musculoskeletal tumors. It is unclear which factors contribute the most to a successful biopsy. The aim of the study was to determine the value of ultrasound-guided core needle biopsy of solid lesions in the musculoskeletal system using a 16-gauge needle.
A retrospective analysis performed at a regional sarcoma center over one year included patients referred for ultrasound-guided biopsy of musculoskeletal soft tissue lesions. At least 6 months' clinical and radiological follow-up, results from repeat or excisional biopsy, or interventional treatment, served as outcome reference. The biopsy procedure and yield were analyzed. The biopsy was classified as 'diagnostic' when a definitive diagnosis could be made on the first biopsy, and 'accurate' when only the malignant or benign nature of the tumor could be determined.
From 102 referrals for biopsy of soft tissue lesions in 2019, a total of 73 biopsies of solid lesions with a 16-gauge cutting needle were included (73 patients). There were 34 males and 39 females, with a mean age of 57.7 years. The overall proportion of diagnostic biopsies was 84%, for malignant lesions 88% and benign lesions 81%. The tumor could be classified as malignant or benign in 12 patients (16%) (accurate biopsy). It was possible to discriminate between malignant and benign lesions in each case. The majority of biopsied lesions were benign 64% (
= 47).
The diagnostic value of ultrasound-guided percutaneous core needle biopsy of musculoskeletal soft tissue lesions performed with 16-gauge needle is good, with a high rate of diagnostic biopsies, both for benign and malignant lesions.

This imaging anatomy study aimed at detecting anatomical variations and potential interconnections of the superior peroneal retinaculum to other lateral stabilizing structures.
We retrospectively reviewed the imaging archives of 63 patients (38 females, 25 males, mean age 32.7, range 18-58 years) with available ankle US, MR and CT images to detect whether US and MR can detect the presence of interconnections between the superior peroneal retinaculum and the anterior talofibular ligament, inferior extensor retinaculum and peroneal tendon sheath. We evaluated the presence of common anatomical variations including low peroneus brevis muscle belly, peroneal tubercle, os peroneum, and retromalleolar fibular groove shape in relation to the presence of superior peroneal retinaculum connections.
The connections of the superior peroneal retinaculum can be revealed on magnetic resonance imaging (MRI) and ultrasound (US). The connection to the anterior talofibular ligament was located (a) inferior to the lateral mconnections between the superior peroneal retinaculum and the anterior talofibular ligament, inferior extensor retinaculum, and superior peroneal retinaculum. Our results are a starting point for further studies on the connections of the superior peroneal retinaculum and the applicability of ultrasound and MRI in assessing their occurrence. Buparlisib Knowledge of the anatomical connections of the superior peroneal retinaculum may help radiologists with the assessment of lateral ankle injuries, and surgeons with treatment planning.
