Imaging of Peripheral Nerves: AJR Expert Panel Narrative Review.

Peripheral nerve imaging provides information that can be critical to the diagnosis, staging, and management of peripheral neuropathies. MRI and ultrasound are the imaging modalities of choice for clinical evaluation of the peripheral nerves given their high soft tissue contrast and high resolution, respectively. This AJR Expert Panel Narrative Review describes MRI- and ultrasound-based techniques for peripheral nerve imaging; highlights considerations for imaging in the settings of trauma, entrapment syndromes, diffuse inflammatory neuropathies, and tumor; and discusses image-guided nerve interventions, focusing on nerve blocks and ablation.

Diagnostic accuracy of ultrasound versus X-ray for distal forearm fractures in children and adolescents: a systematic review and meta-analysis.

PURPOSE: Utilizing ultrasound for the detection of distal forearm fractures in children presents a potential safe and radiation-free alternative compared to X-ray. METHODS: A systematic review was undertaken to compare the diagnostic accuracy of ultrasound in detecting distal forearm fractures in children with X-ray imaging within the period spanning January 2010 to August 2023. The electronic databases MEDLINE and Cochrane CENTRAL were utilized for data retrieval. The QUADAS-2 tool was employed to assess the quality of the included studies. Subsequent statistical analysis was performed to calculate pooled sensitivity and specificity, positive and negative likelihood ratios, as well as the diagnostic odds ratio. RESULTS: Our meta-analysis included seventeen studies, encompassing a total of 2003 patients, 2546 ultrasound scans, and 1203 fracture cases as identified by the reference test (X-ray). The pooled sensitivity and specificity were 0.96 (95% CI: 0.93-0.98) and 0.96 (95% CI: 0.89-0.98), respectively. The positive likelihood ratio was 13.40 (95% CI: 7.97-21.50), the negative likelihood ratio was 0.06 (95% CI: 0.04-0.1), and the pooled diagnostic odds ratio was 209 (95% CI: 92.20-412.00). Our statistical analysis revealed low heterogeneity within our studied cohort. CONCLUSIONS: Our study indicates that ultrasound exhibits exceptionally high accuracy in the detection of distal forearm fractures in children and adolescents. It can be employed safely to either confirm or rule out a fracture, thus circumventing the need for potentially harmful radiation exposure in this vulnerable population. Future research endeavors should focus on establishing a universally accepted protocol for training and scanning methods to standardize practices and eliminate disparities in diagnostic procedures.

The Beauty of Musculoskeletal Ultrasound: Spot Diagnoses.

INTRODUCTION: Ultrasound is a powerful technique in musculoskeletal (MSK) imaging, and it can replace MR imaging in many specific clinical scenarios. This article will feature some common and less common spot diagnoses in musculoskeletal ultrasound. SPOT DIAGNOSIS: Cases were collected by members of the Educational Committee of the ESSR ( European Society of Musculoskeletal Radiology) with expertise in musculoskeletal ultrasound. Sixteen clinical entities are discussed based on the features that allow US spot diagnosis. CONCLUSION: Clinical history, location, and ultrasound appearance are the keys to spot diagnoses when performing musculoskeletal ultrasound. KEY POINTS: · Musculoskeletal ultrasound can be the primary and only modality in common spot diagnoses in specific clinical settings.. · Clinical history, location, and ultrasound appearance are keys to spot diagnoses.. · Knowledge of spot diagnoses in musculoskeletal ultrasound facilitates daily clinical practice..

Sonoanatomy of the ilioinguinal, iliohypogastric, genitofemoral, obturator, and pudendal nerves: a practical guide for US-guided injections.

The ilioinguinal, iliohypogastric, genitofemoral, obturator, and pudendal nerves are the major sensory nerves that may be involved in chronic groin and genital pain with a significant impact on the quality of life of patients. The diagnosis remains clinical, and US-guided diagnostic injections using an anesthetic may aid in confirming the clinical suspicion. The anatomy of the peripheral nerves can be successfully studied using imaging. High-resolution ultrasound is increasingly used in the clinical setting for visualizing small peripheral nerves, and magnetic resonance imaging provides an anatomical overview of the relationship between small nerves and surrounding structures. In this pictorial assay, we review the anatomy and clinical relevance of the ilioinguinal, iliohypogastric, genitofemoral, obturator, and pudendal nerves. We summarize the various techniques for ultrasound identification, and present the ultrasound-guided infiltration techniques for injecting the ilioinguinal, iliohypogastric, genitofemoral, obturator, and pudendal nerves. Corresponding magnetic resonance images and clinical photos of the probe placement technique are provided for anatomical correlation. This paper is aimed to serve as a practical technical guide for physicians to familiarize themselves with the ultrasound anatomy of the major inguinal sensory nerves and to enable successful ultrasound identification and ultrasound-guided diagnostic or therapeutic infiltrations for pain management of the ilioinguinal, iliohypogastric, genitofemoral, obturator, and pudendal nerves.

Clinical indications for musculoskeletal ultrasound updated in 2017 by European Society of Musculoskeletal Radiology (ESSR) consensus.

OBJECTIVES: To update the 2012 European Society of Musculoskeletal Radiology (ESSR) clinical consensus guidelines for musculoskeletal ultrasound referral in Europe. METHODS: Twenty-one musculoskeletal imaging experts from the ESSR participated in a consensus study based on a Delphic process. Two independent (non-voting) authors facilitated the procedure and resolved doubtful issues. Updated musculoskeletal ultrasound literature up to July 2017 was scored for shoulder, elbow, wrist/hand, hip, knee, and ankle/foot. Scoring of ultrasound elastography was included. The strength of the recommendation and level of evidence was scored by consensus greater than 67% or considered uncertain when the consensus was consensus less than 67%. RESULTS: A total of 123 new papers were reviewed. No evidence change was found regarding the shoulder. There were no new relevant articles for the shoulder, 10 new articles for the elbow, 28 for the hand/wrist, 3 for the hip, 7 for the knee, and 4 for the ankle/foot. Four new evidence levels of A were determined, one for the hip (gluteal tendons tears), one for the knee (meniscal cysts), one for the ankle (ankle joint instability), and one for the foot (plantar plate tear). There was no level A evidence for elastography, although for Achilles tendinopathy and lateral epicondylitis evidence level was B with grade 3 indication. CONCLUSIONS: Four new areas of level A evidence were included in the guidelines. Elastography did not reach level A evidence. Whilst ultrasound is of increasing importance in musculoskeletal medical practice, the evidence for elastography remains moderate. KEY POINTS: • Evidence and expert consensus shows an increase of musculoskeletal ultrasound indications. • Four new A evidence levels were found for the hip, knee, ankle, and foot. • There was no level A evidence for elastography.
