“…We used also SMI in our study to overcome these technical defects. In a literature review, we found four (4) studies investigating intraneural vascularity of median nerve in CTS by SMI 26 27 28 29 . However, the main research focus in Karahan et al 26 and Chen et al 27 was the comparison of SMI and Doppler US.…”

“…However, in our study, similar with the report of Chen et al 27 , blood flow display ratios of 1 and above and 2 and above are observed in a higher percentage in CTS patients. In the study of Nam et al 28 , unlike other researcher, both monochrome SMI and color SMI were performed and vascularization was quantified using a computer program. In this study, vascularity was shown to be higher in CTS patients than in controls, which is similar to our study and the study by Chen et al.…”

“…However, superb microvascular imaging (SMI) is a new ultrasound technology so that it can capable of differentiate blood flow signals from artefacts by using a newly developed algorithm 25 . In CTS, hypervascularization of the median nerve has been shown by SMI 26 27 28 29 . To the best our knowledge, there is not any study assessing median nerve hypervascularity by using SMI in PsA.…”

Background It is well known that the carpal tunnel syndrome (CTS) is the most widespread peripheral nerve entrapment syndrome throughout the world. CTS can also be seen more often in rheumatic disease, especially in psoriatic arthritis (PsA). Usage of ultrasonography to diagnose CTS has been the subject of investigations for many years. Superb microvascular imaging (SMI) is a newly developed ultrasonographic technique to visualise vascularity. More recently, there have been some studies on the diagnosis of CTS with SMI. However, a review of the literature reveals that there there has been no study on the diagnosis of CTS in PsA. This is the subject of the present report, where we evaluate the diagnostic value of SMI in CTS in patients with PsA. Materials and methods 30 PsA patients (56 wrists) and 26 healthy volunteers (52 wrists) were examined in the study. Demographic and clinical features were recorded carefully. All participants underwent a standard electrodiagnostic study (EDS) and ultrasonographic examination within a maximum of one week. CTS was diagnosed using EDS. The vascularity of the median nerve was examined using a new ultrasonographic technique. SMI signals were graded from 0 to 3. Results There were no significant differences between groups, with respect to their age, gender, body mass index, smoking status, and hand dominance. Although CTS was diagnosed in 9 patients (14 wrists) in the PsA group, CTS was not diagnosed for any patient in the control group (p=0.002). The blood flow display ratio of SMI in the median nerve was markedly higher in CTS patients than with controls (median (25th, 75th percentile): 2(0.75, 2), 1(0, 2); p=0.014; respectively) or compared with CTS-free PsA patients (2(0.75, 2), 1(0, 2); p=0.030; respectively). There was no remarkable difference between PsA patients and healthy controls with respect to the median nerve’s blood flow display ratio (median (25th, 75th percentile): 1(0, 2), 1(0, 2); p=0.164; respectively). Conclusion To the best our knowledge, this is the first study assessing SMI in the diagnosis of CTS in PsA patients. We concluded that SMI has important diagnostic value in PsA patients for diagnosing CTS.

“…With different targeting CTS cases and using either static strain elastography (tissue compression produces strain) 5 or share wave elastography (focused acoustic radiation force from a linear ultrasound array), 6 MN stiffness was reported, and its elastoscan determined the early pathophysiological changes that are caused by CTS. [7][8][9][10] This study is an extension of the study by Lasheen et al, 11 which aimed to compare CTS patients and healthy volunteers regarding the ultrasound and sonoelastography (SE) of the MN at the wrist and the later correlation to nerve conduction study (NCS) results and included increased stiffness of MN affected by CTS with positive correlations with NCSs. In this paper, we focused on the symptomatic and the functional evaluation in correlation to MN elasticity, its ultrasound parameters, and the electrodiagnostic grading of primary CTS patients.…”

Objectives: This study focused on the symptomatic and the functional evaluation in correlations to median nerve elasticity, its ultrasound parameters, and the electrodiagnostic grading of primary carpal tunnel syndrome (CTS) patients. Patients and methods: In the case-control study, 100 wrists of 57 CTS patients (54 females, 3 males; mean age: 39±9.8 years; range, 20 to 60 years) clinically diagnosed according to the American Academy of Neurology Clinical Diagnostic Criteria were evaluated between December 2019 and December 2020. The control group included 110 nondiseased wrists of 55 sex- and age-matched healthy subjects (males 7, females 48; mean age: 35.7±10.3 years; range 20 to 58 years). Functional assessment using Hi-Ob-Db clinical scale, electrodiagnosis, ultrasonographic screening, and elasticity evaluation were done for all patients. Results: CTS patients had an increased stiffness of the median nerve compared to controls. Functional stages were positively correlated with the ultrasonographic parameters and the electrodiagnostic stages of CTS. The elastogram of clinically diagnosed patients was revealed more stiffness of the MN, with negative electrodiagnosis results. Conclusion: Clinically diagnosed CTS could be missed by the electrodiagnosis but then properly figured by ultrasonography and potentially graded by sonoelastography. Sonoelastography may be an effective method for early diagnosis and appropriate grading of CTS.
