“…Routinely assessing sagittal reconstructions of the spine is crucial for detection of vertebral body compression fractures in nontrauma patients at abdominal multidetector CTs [11]. Multiplanar reconstructions of the vertebral column improve diagnostic evaluation of the spine [4,24,25].…”

“…Evaluation of the thoracolumbar spine on strictly anatomically aligned axially orientated images can be challenging and pathologies may be missed [9]. Thus, multiplanar reconstructions in the coronar and sagittal plane are routinely computed to improve the detection and evaluation of spinal and extraspinal pathologies [10][11][12]. However, the use of coronal and sagittal reformatted images alone results in a high number of missed soft tissue and skeletal findings [13].…”

OBJECTIVE Automated analysis of abdominal CT has advanced markedly over just the last few years. Fully automated assessment of organs, lymph nodes, adipose tissue, muscle, bowel, spine, and tumors are some examples where tremendous progress has been made. Computer-aided detection of lesions has also improved dramatically. CONCLUSION This article reviews the progress and provides insights into what is in store in the near future for automated analysis for abdominal CT, ultimately leading to fully automated interpretation.

“…Compared with MRI, CT is more available, requires less time and has better spatial resolution. 9,10 Although bones can be removed on singleenergy CT images, the surrounding trabecular structures complicate the visualization of vertebral oedema. 5,[11][12][13][14] With the advancements in dual-energy CT technology, material decomposition and the elimination of misregistration artefacts are possible.…”

Objective: To prospectively evaluate the ability of dual-energy CT (DECT), compared with MRI, to identify vertebral compression fractures in acute trauma patients. Methods: This institutional review board-approved study included 23 consecutive patients with 32 vertebral fractures who underwent both DECT and MRI of the spine between February 2014 and September 2014. A total of 209 vertebrae were evaluated for the presence of abnormal bone marrow attenuation on DECT and signal on MRI by five experienced radiologists. The specificity, sensitivity, predictive values and intraobserver and interobserver agreements were calculated. Results: MRI revealed a total of 47 vertebrae (22.4% of all vertebrae) and DECT revealed 44 vertebrae (21.0% of all vertebrae) with oedema. Using MRI as the reference standard, DECT had sensitivity, specificity, positive-predictive value, negative-predictive value and accuracy of 89.3, 98.7, 95.4, 96.9 and 96.6%, respectively. With respect to establishing the presence of oedema, the interobserver agreement was almost perfect (k 5 0.82), and the intraobserver agreement was substantial (k 5 0.80). Conclusion: Compared with MRI, DECT can provide an accurate demonstration of acute vertebral fractures and can be used as an alternative imaging modality for the assessment of vertebral fractures in patients with contraindications for MRI. Advances in knowledge: Distinguishing of acute and chronic vertebral compression fracture is important for treatment choices. DECT is very fast compared with MRI and is an alternative imaging modality for the assessment of vertebral fractures in patients with contraindications for MRI.

Unreported Vertebral Body Compression Fractures at Abdominal Multidetector CT

Abstract: Most clinically important vertebral body compression fractures in nontrauma patients at risk for low bone mineral density may go unreported at abdominal multidetector CT if sagittal reconstructions are not routinely evaluated.
