The Characteristics of Regional Bone Quality in the Cervical Vertebrae Considering BMD
The Characteristics of Regional Bone Quality in the Cervical Vertebrae Considering BMD
Data of CT images and the femoral neck BMD were obtained from 99 patients who underwent the
 cervical CT and BMD simultaneously (the gap of both studies was within 6 months) from April
 2009 to December 2014. There were 52 females and 47 males. The mean age was 63.7 year
 (female: 63.4 years, male: 64.1; range 32-86 years). The patient was excluded who had any
 destructive pathology or severe spondylosis in the cervical pedicle and the cervical lateral
 mass. Patients were divided into three groups according to femoral neck BMD (Group A, T-score
 ≥-1; Group B, -2.5<T-score<-1.0; Group C, T-score≤-2.5). Group A had normal BMD patients,
 Group B had lower normal patients including osteopenic patients and Group C presented
 osteoporotic patients. The mean HU numbers of cortical bone area in the vertebral canal (cHU,
 the medial wall of the lateral mass), the posterior wall of transverse foramen (fHU), the
 medial (mHU), lateral wall (lHU) and trabecular area of pedicle (pHU) were measured on the
 axial CT images in clinical images.
Inclusion Criteria:

 -  Patients who underwent the cervical CT and BMD simultaneously (the gap of both studies
 was within 6 months)

 Exclusion Criteria:

 -  Who had any destructive pathology or severe spondylosis in the cervical pedicle and
 the cervical lateral mass.
