Imaging evaluation of patients with spinal deformity.

摘要: CT myelography and MRI provide the best means of preoperatively assessing patients with spinal deformities. Owing to its noninvasive nature superior soft-tissue contrast, represents single modality in evaluation a patient any deformity. allows complete preoperative surgical planning obviates need for additional studies. Screening entire cord deformity is accomplished sagittal coronal (as needed) T1W images. These images allow assessment compression, tethering, syrinx, enlargement, Arnold-Chiari malformation. Evaluation compression at apex curve most important consideration other than diagnosis intrinsic abnormality. Subsequent or axial T2W may be helpful if specific abnormalities are noted on screening Coronal particularly prominent curves those vertebral anomalies. Additionally, useful suspected diastematomyelia. Advances hardware software design have resulted marked improvements ability satisfactorily image all aspects New phased array coils rapid imaging larger portions spine. For instance, spine can performed child same length time that would been necessary lumbar examination when was it's infancy. The use fast spin-echo also permits more acquisition times. remains who cannot undergo such as multilevel central stenosis dynamic information obtained during myelogram might helpful. only canal metallic instrumentation place.
