[1] Chondrocalcinosis is an observation that can be visualized through diagnostic imaging tests such as X-rays, CT, MRI, and ultrasound.

[2] Buildup of calcium phosphate in the ankle joints has been found in about 50% of the general population, and may be associated with osteoarthritis.

[11] Chondrocalcinosis can be visualized on projectional radiography, CT scan, MRI, ultrasound, and nuclear medicine.

[1] CT scans and MRIs show calcific masses (usually within the ligamentum flavum or joint capsule), however radiography is more successful.

[1] At ultrasound, chondrocalcinosis may be depicted as echogenic foci with no acoustic shadow within the hyaline cartilage.
