Some comments about magnetic resonance image for cervical disc displacement

A retrospective and cross sectional survey was carried out in 52 patients with cervical disc displacement who were screened by magnetic resonance at Viet Duc Hospital and Military Hospital 103 from Jan 2003 to Oct 2004. Sites of common displacement: C5-C6 (36.61%); C4-C5 (26.79%); C3-C4 (23.21%); C6-C7 (11.61%); C7-D1 (1.79%). Disc displacement in one layer was 42.31%, in two 11.54%, in three layers 34.61%, in four 11.54%, in centre 71.43%, beside centre 25%, in foramen 3.57%. Displacement image was looked clearly in T1W and T2W image. 100 displaced discs reduced signal in T2W image, 63.46% reduced disc height, 42.31% increased medulla signal equal with site of displacemen in T2W image
