AIm:The carpal tunnel syndrome (CTS) is the commonest compressive neuropathy. Electromyography (EMG) is accepted as gold standard in diagnosis of CTS. However, pathologies and variations that are associated with a various findings may lead to failure. sOnuÇ: Klinik ve EDT ile KTS tanısı alan hastalarda bilek MRİ eşlik eden patolojileri ortaya koyabilmektedir. Ek patolojiler uygulanacak cerrahi şeklini değiştirebileceği gibi, postoperatif başarısızlığı da azaltılacaktır. Özellikle belirgin predispozan faktörü olmayan, tek taraflı KTS öyküsü bulunan, kliniğinde şüpheli semptomları olan olgularla ve endoskopik cerrahi planlanan hastalara el bileği MRİ önerilir.

“…Likewise, it has been reported that MRI is capable or delivering more detailed images of the wrist anatomy in cases with partial or no recovery despite surgical intervention (3,11,19,25,28). Besides, it is known that MR is an objective and non-invasive method compared to EMG.…”

“…Its long axis is parallel to the flexor retinaculum in most cases. As it is traced distally, median nerve divides into its terminal branches and this anatomical formation can be seen in the most distal part of the carpal tunnel at the level of metacarpal bases (9,15,19).…”

“…These findings with the complement of EMG can be supportive to the diagnosis. On the other hand, MR findings depend on the comments of the radiologist as there is no parametric value differentiating normal and pathologic wrists, contrary to EMG (9,10,12,15,19). The aim of this study was to try to find parametric ratios to explain the pathophysiology of carpal tunnel syndrome using MR.…”

ABSTRACTaIM: The aim of this study was to try to find parametric ratios for the diagnosis and pathophysiology of carpal tunnel syndrome using MR. MaterIaL and MetHOds:Dominant side wrist MRI examinations of 27 female carpal tunnel patients and 21 normal females were compared. The carpal tunnel contents area / carpal tunnel cross section area ratio was defined, analysed and discussed with the literature. resuLts: Carpal tunnel contents / wrist area ratios of the carpal tunnel patients were measured and compared with the control group. This comparison revealed that the proportion of the contents of the carpal tunnel is increased in the carpal tunnel syndrome patients. Palmar bowing was found to be increased and median nerve cross section area was found to be increased at the proximal entrance of the carpal tunnel.cOncLusIOn: As Phalen has postulated, the volume of the contents of the carpal tunnel were found to be increased in the carpal tunnel syndrome patients. Carpal tunnel cross section areas remained the same with the control group. This increase can be demonstrated by MRI imaging which can provide an evidence for the pathophysiology of carpal tunnel syndrome.keywOrds: Carpal tunnel syndrome, Area measurement, Ratio ÖZ aMaÇ: Bu çalışmanın amacı, el bileği MR incelemesiyle tespit edilen karpal tünel kapsamı/karpal tunel alanı oranları ile karpal tunel sendromuna diagnostik ve patofizyolojik bir yaklaşımda bulunmaktır. yÖnteM ve gereÇLer: 27 karpal tunel hastası kadın ile dominant el bileği MR incelemesi yapılan 21 kadından oluşan kontrol grubunun el bilek MR ları karşılaştırılmıştır.

Bu kapsam artışına karşılık karpal tunel yüzey alanlarında anlamlı bir artış tespit edilmemiştir. Bu bulgu MR ile gösterilebilmektedir ve karpal tunel sendromunun fizyopatolojisinin anlaşılması konusunda bir kanıt olabilmektedir.anaHtar sÖZcÜkLer: Karpal tunel sendromu, Alan ölçümü, Oran

“…Another reason to use MRI in patients with peripheral neuropathies is the potential to serve as an adjunct in the diagnosis and management of these patients (Weis et al, 1986;Britz et al, 1996;Grant et al). A number of other studies have been published investigating the diagnostic accuracy of MRI for CTS (Pasternack et al, 2003;Kleindienst et al, 1996;Kleindienst et al, 1998;Mesgarzadeh et al, 1989b;Murphy et al;Oneson et al;Pierre-Jerome et al, 1996a;Radack et al;Soccetti et al, 1992;Timins et al, 1996). Our MRI protocols mainly focused on the assesment of morphologic anatomy of carpal tunnel and do not include functional MRI techniques.…”

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.
