It is the wish of every patient and his family to know the test method of cervical ankylosis. So, what is the definitive test for cervical ankylosis? The following is the explanation of experts on the examination of cervical ankylosis, hope it can bring you help. The examination methods of cervical ankylosis are: 1. Spinal cord CT: often combined with myelography. The spinal cord can be seen to be mildly thickened and unevenly dense. 2, spinal cord MRI: swelling of the spinal cord can be seen, mostly with inhomogeneous long T1, long T2 signal abnormalities. 3, myelography: diffuse swelling of the spinal cord is common, or may be normal. It is mainly used in cases with atypical clinical manifestations and to differentiate from other diseases. Acute phase examination may cause aggravation of the disease. 4.Blood picture: mostly no abnormal changes, acute stage and co-infection can be seen in the white blood cell count increased, neutrophil ratio increased. Most of the pressure is normal, but if the spinal cord swelling is obvious and causes incomplete obstruction, the pressure is reduced. Protein quantification is often mildly elevated, with an increase in gamma globulin. The cell count is mildly increased or normal, with a predominantly monocytic classification. These changes are mostly seen in the acute phase.
