ISCD CCD study guide
ISCD CCD · Work through your exam, one topic at a time.
The Certified Clinical Densitometry (CCD®) credential is issued by the International Society for Clinical Densitometry (ISCD), a society founded in 1993 that describes itself as an international network of more than 2,500 members and certified professionals from over 55 countries. ISCD frames certification as "formal recognition of the specialized knowledge, skills, and experience" of professionals in skeletal health assessment, and lists CCD alongside the Certified Bone Densitometry Technologist (CBDT®) credential. The CCD is aimed at clinicians and other practitioners who interpret and act on bone densitometry studies rather than at technologists acquiring scans, and ISCD positions it within a suite of offerings that also includes recertification options, maintenance of certification, a certification registry, and an appeals process. Because content is grounded in skeletal health assessment, preparation should center on the ISCD Official Positions - adult, pediatric, and FRAX - which ISCD publishes as best clinical practice guidelines, together with the Quality Bone Densitometry for Clinicians course, the DXA Atlas, the Ask an Expert forum, and the Journal of Clinical Densitometry. Topics on this exam: Clinical Densitometry Knowledge and Skills and Skeletal Health Assessment Practice. The ISCD CCD study guide has 2 sections and about 739 words.
01Clinical Densitometry Knowledge and Skills
This domain tests whether you can move correctly from scan acquisition to interpretation. Know the technology distinctions first: DXA uses two x-ray energies to separate bone from soft tissue; QCT measures volumetric density in mg/cm³; pDXA and QUS are peripheral tools with limited monitoring roles.
383 words, about 2 min02Skeletal Health Assessment Practice
This domain covers the clinical workflow around the scan: appropriate referral, acquisition quality, reporting, and risk communication. Know who should be tested-women 65 and older, men 70 and older, younger adults with risk factors, and anyone with fragility fracture or conditions/drugs that threaten bone (glucocorticoids, aromatase inhibitors, androgen deprivation, hyperparathyroidism, malabsorption).
