Purpose

To evaluate patients with cervical stenosis with DWI and CSF flow studies.

Methods & Materials

Patients with clinical symptoms of cervical stenosis were referred by neurologists and neurosurgeons for MR imaging (GE 1.5 Tesla Milwaukee, Wisconsin and Philips 1.5 Tesla Gyroscan Intra, the Netherlands: Axial and Sagittal T2 (TR 2300; TE 100; NEX 8; FOV 20; 256 x 512 Matrix; slice thickness 3/0.3mm; ETL 16); Sagittal Cine CSF Flow (TR 14; TE 11; FOV 20; 96 x 256 matrix; pulse velocity 5cm/s; slice thickness 8mm; peripheral pulse gated); Sagittal DWI with ADC map (multishot SE; EPI 9; TE 18; peripheral pulse gated; FOV 22; 128 x 128 matrix; slice thickness 5/0.5mm; b-value 400 sec/mm2). ADC maps were obtained utilizing existing software available on the MRI scanner. Images were reviewed by two neuroradiologists blinded to the patientsâ
