“…70–73 Both ultrasound-guided steroid injections and surgical treatment of carpal tunnel syndrome lead to prompt and sustained reductions in nerve size as measured by cross-sectional area. 70–72,74,75 When Cartwright and colleagues 70 looked at median nerve vascularity in conjunction with nerve size, both decreased in tandem in patients with carpal tunnel syndrome after ultrasound-guided steroid injections around the median nerve. Nerve echogenicity, measured by examiner rating, showed a similar time course of improvement.…”

There is an inherent conflict between interpreting ultrasound imaging, which generates rich, highly textured complex representations of 3-dimensional space, and the rendering of these images into discrete measures for statistical analysis Reducing images to a small set of numbers, by necessity, ignores vast amounts of useful data, but the process is a prerequisite for generating objective information that can be shared by the clinical community. This article illustrates how ultrasound imaging is used in quantitative ways. The goal is not to supplant or diminish the importance of descriptive findings but to make the field amenable to statistical methods and standards for making diagnoses and designing therapeutic trials of new interventions. The discussion focuses first on muscle ultrasonography, a technique that was developed more than a decade earlier than nerve ultrasound, to illustrate key elements in determining how to best extract quantitative information from complex images. The discussion then applies some of these same principles to the study of 2 common nerve disorders.

“…Intraneural vascularity has been proposed as an additional parameter in the diagnosis of CTS, sometimes being the only detectable finding [34,35]. Recent studies have shown that endoneural hypervascularity is correlating with the severity of the median nerve lesions evaluated through electrophysiologic studies [36,37].…”

Aims: The ultrasonographic (US) evaluation of the median nerve at the level of the carpal tunnel outlet (CTO) and mid forearm in pediatric patients with mucopolysaccharidosis type II (MPS II) and comparison with healthy subjects. Material and method: Fifteen children with MPS II and 44 healthy children were included in the study and they were divided into three age groups. The cross-sectional area, the appearance of the nerve, and the ratio of the cross-sectional areas were evaluated by US. Results: At the level of the CTO the mean area of the nerve was increased in all MPS II groups compared with the correspondent healthy age groups and the differences were statistically significant (p<0.01). At the level of the mid forearm the differences were statistically significant only for the first age group. Other US findings at the level of the CTO in the MPS II groups were represented by hypoechogenicity (86.67 % on the right and 93.33% on the left), thickened fascicles (80% bilaterally), irregular contour (53.33% bilaterally) and the presence of the Doppler signal including the nerve (26.67 % on the right and 33.33 % on the left). The CTO/mid forearm cross-sectional area ratio was higher in all MPS II age groups and the differences were statistically significant (p<0.001). Conclusion: In patients with MPS II there are significant US changes in the size and aspect of the median nerve.
