Opportunistic Osteoporosis Screening: Addition of Quantitative CT Bone Mineral Density Evaluation to CT Colonography

Quantitative CT to assess bone mineral density as a diagnostic tool for osteoporosis and related fractures

Osteoporosis is the most common metabolic bone disorder. It is defined as “a skeletal disease, characterized by low bone mass and microarchitectural deterioration of bone tissue, with a consequent increase in bone fragility and susceptibility to fracture” [1]. Bone is a highly metabolic tissue, incorporating multiple functions such as stabilization of the body, protection of the inner organs an...

CT colonography and colorectal screening.

Screening CT colonography: how I do it.

OBJECTIVE The purpose of this article is to detail an approach to CT colonographic screening that has evolved at one institution. CONCLUSION CT colonography is a rapidly advancing technology that has great potential for addressing a deadly but preventable disease-colorectal carcinoma. CT colonography is ideally suited for widespread screening of asymptomatic adults and has become an integral ...

CT colonography screening: ready for prime time?

Every year more than one million new patients are diagnosed with colon cancer worldwide. Although multiple prospective randomized trials and observational studies have demonstrated that mortality from colon cancer can be reduced with screening and removal of adenomatous polyps, compliance with screening guidelines remains low. Recent CT colonography (CTC) trials have shown that CTC is capable o...

Quantitative CT assessment of bone mineral density in dogs with hyperadrenocorticism

Canine hyperadrenocorticism (HAC) is one of the most common causes of general osteopenia. In this study, quantitative computed tomography (QCT) was used to compare the bone mineral densities (BMD) between 39 normal dogs and 8 dogs with HAC (6 pituitary-dependent hyperadrenocorticism [PDH]; pituitary dependent hyperadrenocorticism, 2 adrenal hyperadrenocorticism [ADH]; adrenal dependent hyperadr...
