“…However, MRI provides an excellent visualisation of the median nerve and of its links with the other carpal tunnel structures and, in particular, it allows for the individuation of either nerve adhesion or compression. Last, a correlation between some MRI parameters and the level of electrophysiologic severity has recently been demonstrated [19,20].…”

The carpal tunnel syndrome is a compressive neuropathy with high incidence rates, and its correct diagnosis, treatment and follow-up may lead to significant benefits in healthcare, social and economic terms. In this review, based on systematic review databases and guidelines, we summarise the appropriate indications for the diagnosis, treatment and follow-up, accompanied, whenever possible, by the levels of evidence and strength of recommendations.

“…Most of the studies accept EMG as the gold standard and attempt to determine the accuracy of other tests in comparison with EMG. 1,[40][41][42][43][44][45][46][47] The aim of this study was to compare the diagnostic accuracy of EMG, US, CT, and MRI for the diagnosis of CTS with the use of the clinical findings as the gold standard.…”

EMG or US could be used as the first-step test in most cases. If they are both available, EMG should be the first choice. They may be performed together when diagnosis is challenging. CT may especially be preferred for bone-related pathological conditions, whereas MRI may be preferred for soft tissue-related pathological conditions. Even though imaging studies have been proven to be powerful diagnostic tools for CTS, no conclusive information currently exists to support replacing EMG with imaging studies.

“…Enlargement of the cross sectional area of the median nerve at the level of distal radio-ulnar joint and at the level of pisiform bone or at the entrance to the tunnel was found to be of diagnostic value for idiopathic CTS in the majority of cases studied (Martins et al, 2008;Uchiyama et al, 2005;Jarvik et al, 2002;Almann et al;Mesgarzadeh et al, 1995;Monagle et al;Kleindienst et al, 1996;Kleindienst et al, 1998). However, several investigators have shown a larger cross-sectional area of the nerve in CTS groups than in controls, even at the hook of the hamate bone level (Almann et al;Mesgarzadeh et al, 1995;Monagle et al).…”

SUMMARY:The objective of this study was to evaluate morphological changes of the median nerve in patients with carpal tunnel syndrome (CTS) and healthy controls, to correlate the MRI findings of wrists. This study compared not only morphological changes of the median nerve and also displayed descriptively structures in carpal tunnel between patients diagnosed with idopathic CTS and healthy controls. Our study involved 60 hand, 30 of hand were evaluated diagnosed with idiopathic CTS and 30 hand as healthy controls bilaterally. Two provocative tests (Phalen's and Tinel's test) were performed on each hand for both the patient group (60 wrist) and the control group (60 wrist). With regard to Phalen and Tinel's test results, 24 and 26 wrists were excluded from patient and control groups respectively. Totally 70 wrists were evaluated, and in terms of cross-sectional area of median nerve at the level of distal radioulnar joint, pisiform bone and the hook of hamate bone by MRI in the patient and control groups. In addition to evaluation of crosssectional area of median nerve, we determined signal intensity of wrists and different localization of the median nerve in the carpal tunnel. Cross-sectional area of the median nerve measured by wrist magnetic resonance at the level of metacarpal bones and signal intensity of wrists may be considered as a valuable indicator to determine patients referred with idiopathic CTS.
