- Low-dose CT hounsfield units: a reliable methodology for . . .
ABSTRACT Objective Studying vertebral bone loss in radiographic axial spondyloarthritis (r- axSpA) has been challenging due to ectopic bone formation We cross- sectionally analysed low- dose CT (ldCT) trabecular bone density Hounsfield units (HU) measurements and calculated inter- reader reliability at the vertebral level in patients with r
- Hounsfield Units measured in low dose CT reliably assess . . .
Objectives: To describe low dose Computed Tomography (ldCT) Hounsfield Units (HU) two-year change-from- baseline values (expressing trabecular bone density changes) and analyse their inter-reader reliability per vertebra in radiographic axial spondyloarthritis (r-axSpA)
- Use of computed tomography for assessing bone mineral density
Assessing local bone quality on CT scans with Hounsfield unit (HU) quantification is being used with increasing frequency Correlations between HU and bone mineral density have been established, and normative data have been defined throughout the spine Recent investigations have explored the utility of HU values in assessing fracture risk, implant stability, and spinal fusion success The
- Assessing bone quality in hounsfield units using computed . . .
Results This review located 34 studies measuring bone density using CT with threshold values, of which, 10 were included in the final review Number of patients ranged from 74 to 283 and cohort ages from 20s to 70 6 years CT threshold values for assessing normal and osteoporotic bone quality ranged from 150 to 179 and 87 to 155, respectively
- Variation in Attenuation in L1 Trabecular Bone at Different . . .
The purpose of this study is to investigate the variation in attenuation val-ues (expressed as Hounsfield units) for L1 vertebral body trabecular bone at different tube voltages used in dual-energy CT (DECT) and to remind physicians to consider changes in at-tenuation values when they approach opportunistic screening for osteoporosis
- What is the role of CT-based Hounsfield unit assessment in . . .
The mean HU value (average of axial, sagittal and coronal measurements) calculated on PACS was used to represent bone density of the vertebral trabecular bone at the concerned level
- Diagnostic efficacy of Hounsfield units in spine CT for the . . .
The goal of this study is to assess BMD using Hounsfield unit (HU) measurements from computed tomography (CT) and to correlate these with DEXA-assessed T-scores in non-degenerative and degenerative patients Methods This study included 80 non-degenerative and 30 de-generative patients who underwent DEXA and spine CT as-sessment
