Because the appreciation and appraisal of. Each level should be compared with the normal range specific for that level. This article lists examples of normal imaging of the pediatric patients divided by region, modality, and age. In this age group, the developmental anatomy of the cervical spine must be correlated with the roentgen appearance. A single number cannot be used as the basis for evaluating spinal cord size. However, our results correlated well with the postmortem studies of Nordquist (1964). Comparison of our data with the literature reveals disparate measurements that vary up to 6 mm from our mean values. laterally to include the mandible superior-inferior to include the upper incisors and lower incisors orientation. At C2 the average ACA was 110 mm2, at C4 it was 121.9 mm2, and at C7 the average ACA was 84.6 mm2. the central ray is centered at the center of the open mouth angle accordingly see 'patient positioning' collimation. The cervical enlargement was found from C4 to C6 and was most evident by comparing the ACA values. A decision to pursue C-spine imaging of any kind should be cross-referenced with the Canadian C-Spine Rule for C-spine imaging due to its high sensitivity and specificity 4. The cord varies in average anteroposterior and transverse diameters from 8.8 mm x 12.4 mm at C2 to 8.7 mm x 14 mm at C4 to 7.4 mm x 11.4 mm at C7. Cervical spine radiographs are indicated for a variety of settings including 1-3: trauma. We measured the anteroposterior and transverse diameters of the cord at each vertebral level and computed the simple product of these diameters to provide a single useful numerical value, termed the approximate cord area (ACA). A thoracic kyphosis is normal when measured at 20-40 degrees. Seven hundred and fifty-six measurements were made from 66 randomly selected MR studies of the cervical spine. The curves of the spine are usually measured in degrees. The purpose of this study was to determine normal measurements of the C1-T3 spinal cord in anteroposterior and transverse planes from MR images and to compare these with previously published data.
