Subchondral lucency refers to a dark area seen on imaging underneath the cartilage of a joint. It can indicate a loss of bone density or a developing bone cyst, which may be associated with conditions like osteoarthritis or avascular necrosis. Further evaluation by a healthcare provider is usually needed to determine the underlying cause.
"Lucency" is a technical term for an area that lets x-rays through tissue and appears darker on the picture. "Peri-screw lucency" is a result of having had a peri-screw inserted into the bone, possibly due to an accident.
ageing or degenertive enthesopathy
A lucency on an X-ray image represents an area absorbing less radioactive energy than the surrounding tissue. Lucent areas appear dark compared to the surrounding area.
Heterogeneous lucency refers to an imaging finding where there are both darker and lighter areas within a tissue, such as seen on a radiograph or CT scan. This can be indicative of a mixed composition of tissues or materials within the area being imaged. In medical imaging, heterogeneous lucency might prompt further investigation to determine the underlying cause.
Lucency on medical imaging, such as X-rays, is caused by the passage of X-rays through less dense tissues like air or fluid. This results in those areas appearing darker on the image. Lucency can be seen in conditions like pneumothorax (air in the chest cavity) or pulmonary nodules (small round growth in the lung).
A lucency area on an X-ray indicates a region where there is less density compared to surrounding tissues, often appearing darker. This can suggest various conditions such as bone loss, the presence of a cyst, infection, or tumors. The specific cause of the lucency must be evaluated in conjunction with clinical findings and additional imaging or tests for an accurate diagnosis.
yes
There is some thinning of the bone in the pelvis.
In dental terms, abnormal lucency refers to an area on a radiograph that appears darker than the surrounding tissues, indicating a potential loss of mineral content or density. This can signify various dental issues, such as dental caries (cavities), periodontal disease, or bone loss. The presence of abnormal lucency often requires further investigation to determine the underlying cause and appropriate treatment.
Ask again, saying which body part is being imaged.
Related to bone condyles that have swelling beneath the surface. The condyles are the rounded lumpy bits at the end of long thin bones: finger bones (phalanges) or thigh (femur). Subchondral odema occurs commonly when thes bones are forced together sometimes with repeated running on hard surfaces sub femoral or tibial chondral/plataeu or when staving your finger during basket ball straight finger compression. Can take a long time to settle but can settle to no symptoms.
