The use of computed tomography attenuation to evaluate osteoporosis following acute fractures of the thoracic and lumbar vertebra.

Background: Relatively few patients have dual-energy x-ray absorptiometry to quantify the magnitude of bone loss as they age. Recent work correlates mean computed tomography (CT) attenuation in the level I (L1) vertebra with bone mineral density (BMD), making it possible to objectively evaluate the magnitude of bone loss in osteoporosis by this method. The aims of this study were to evaluate the utility of using CT scans in patients with acute thoracic and lumbar spine fractures to diagnose osteoporosis and using CT attenuation to evaluate the association between age and BMD.

Parents' reports predict abnormal investigations in global developmental delay.

Aims: To identify symptoms reported by parents that predict abnormal laboratory investigations in preschoolers with global developmental delay (GDD).

Methods: A cross-sectional descriptive study of 81 boys and 38 girls, with a mean age of 43.5 months (SD = 13.

Multi-section CT angiography for detection of cerebral aneurysms.

Background And Purpose: Multi-section CT has great potential for use in vascular studies. Our purpose was to determine the accuracy of multi-section CT angiography in detecting cerebral aneurysms compared with digital subtraction angiography or surgery.

Methods: One hundred consecutive patients who underwent multi-section CT angiography and either digital subtraction angiography or surgery were included in the study.
