The purpose was to assess osteoporotic vertebral fractures and other spinal lesions in sagittal reformations obtained from
routine multidetector computed tomography (MDCT) studies of the thorax and abdomen, to compare sagittal reformations with
axial images in detecting these lesions and to investigate how frequently they were missed in the official radiology report.
Routine abdominal or thoracoabdominal MDCT using a standard protocol was performed in 112 postmenopausal women. Axial images
and sagittal reformations were analyzed separately by two radiologists in consensus and were compared in order to evaluate
how often spinal lesions could be detected. In addition the official radiology reports were assessed to determine how many
of those abnormalities were identified. Spine abnormalities were visualized in 101/112 postmenopausal women. In 27 patients
osteoporotic vertebral deformities were found; 6 of these were shown in the axial images, but none of these were diagnosed
in the official radiology report. Additional abnormalities included degenerative disc disease, osteoarthritis of the facet
joints, scoliosis, hemangiomas and bone metastases. In only 9/101 patients spine abnormalities were mentioned in the radiology
report. Sagittal reformations of standard MDCT images provide important additional information on spinal abnormalities; in
particular, osteoporotic vertebral deformities are substantially better detected.
