Comparison of Magnetic Resonance Imaging and Ultrasonography in Diagnosing and Grading Carpal Tunnel Syndrome: A Prospective Study

Carpal Dimensions by Plain Wrist Radiography in Patients with Severe Carpal Tunnel Syndrome

“…Recently, ultrasound is increasingly used for the diagnosis of CTS. By measurement of the cross-section area of the median nerve in a different area of the patients' wrist and compression with a control group, Bagga uncovered that ultrasound can be beneficial for diagnosis and grading of CTS [ 7 ]. Drakopoulos examined 96 patients after which they proved that the cross-section area of the median nerve at the pisiform level measured by the ultrasound can be as valuable as electrodiagnostic studies [ 1 ].…”

“…There are controversial results concerning the usefulness of ultrasound findings for evaluation of CTS [ 3 – 5 ]. Moreover, MRI and anthropometric measurements are used for diagnosis and prediction of the treatment [ 6 , 7 ]; however, they cannot be replaced for EDS as a gold standard diagnostic test. Recently, digital X-ray machines have proven popular and medical imaging softwares can measure decimal distances in digital images.…”

The prognostic value of median nerve thickness in diagnosing carpal tunnel syndrome using magnetic resonance imaging: a pilot study

“…On the other hand, MRI helps pinpoint the relevant factors causing CTS. Furthermore, in severe to extreme CTS, the demarcation of the median nerve is poor and the signal intensity of the nerve shows fasciculation, and therefore MRI is more useful in advanced CTS [7,16,25]. The MNCSA is also a useful morphological parameter for the evaluation of CTS.…”

Quantitative parameters of diffusion tensor imaging in the evaluation of carpal tunnel syndrome

“…Numerous studies have been conducted to investigate the ability of different MRI parameters to diagnose CTS (8,10,21,38). The CSA of the median nerve has been found to be a good diagnostic parameter (38)(39)(40) as well as a good indicator for grading CTS (41). Other MRI semiquantitative parameters, such as the flattening ratio of the median nerve, the flexor retinaculum bowing ratio, and the signal intensity ratio of the median nerve compared to that of the hypothenar muscle, have been found to have variable values in the diagnosis and grading of CTS (42)(43)(44).…”
