Computed Tomography (CT) effectively measures vertebral bone mineral density, revealing age-related bone loss, particularly in women. This method identifies individuals at higher fracture risk, including those with various medical conditions.

Area of Science:

  • Radiology
  • Orthopedics
  • Endocrinology

Background:

  • Bone mineral density assessment is crucial for diagnosing osteoporosis and predicting fracture risk.
  • Age-related bone loss affects both sexes, with a pronounced decline in women during middle age.
  • Various medical conditions and treatments can negatively impact bone health.

Purpose of the Study:

  • To evaluate the utility of Computed Tomography (CT) for assessing bone mineral content in the vertebral spongiosa.
  • To compare bone mineral content in healthy individuals across different age groups and sexes.
  • To investigate bone mineral content in patients with specific pathologies and identify differences compared to healthy controls.

Main Methods:

  • Application of the Genant and Cann method for quantitative Computed Tomography analysis.

  • Examination of 164 healthy volunteers (males and females) and 108 patients.
  • Inclusion of patient groups with osteoporotic fractures, post-gastrectomy status, renal failure, hyperparathyroidism, Cushing syndrome, and corticosteroid therapy.

    • Main Results:

    • A progressive decrease in bone mineral content with increasing age was observed in both healthy males and females.
    • Bone mineral loss was most severe in females between their 4th and 5th decades of life.
    • Patients with various pathologies exhibited significantly lower bone mineral values compared to healthy individuals.

    Conclusions:

    • Computed Tomography is a valuable tool for quantifying bone mineral content in the vertebral spongiosa.
    • CT assessment can aid in identifying individuals at risk of fractures.
    • The study highlights the impact of age, sex, and specific medical conditions on bone mineral density.
