Lucency meaning (medicine) A pale area revealed in radiography, computed tomography, or similar examination technique.

What does oblique lucency mean?

Oblique. The base of 5th metatarsal has a transverse lucency that represents an avulsion fracture and, on the oblique, a longitudinal lucency that represents a normal apophysis which is close to fusing.

What is white matter lucency?

CT scans were evaluated by a neuroradiologist for the presence or absence of white matter lucencies (WML). WML were defined as patchy or diffuse areas of decreased attenuation involving only white matter and with no change in adjacent ventricles or sulci.

Is lucency a fracture?

The lucency overlying the distal radius, under careful examination, is seen to extend OUTSIDE of the bone into the soft tissues (green arrows). This is a skin fold that projects over the bone but is NOT a fracture.

How long can you live with white matter disease?

It is not possible to stop disease progression, and it is typically fatal within 6 months to 4 years of symptom onset. People with the juvenile form of metachromatic leukodystrophy, which develops between the age of 4 and adolescence, may live for many years after diagnosis.

What is cortical lucency?

In its typical location in the diaphysis of a long bone, it usually presents on radiographs and CT as a cortically based lucent lesion surrounded by sclerosis and reactive focal cortical thickening. 1. The lucency — or nidus — consists of highly vascular, cellular elements that produce an osteoid matrix.

What kind of doctor treats white matter disease?

A neuroradiologist is a doctor who is certified in general radiology and has also undergone specialty training, often with an added board certification in imaging of the brain, spine, and nerves. With this training, they’re able to recognize both common and uncommon disorders that affect the nervous system.

At what age does white matter disease start?

This condition occurs between 12 and 18 months of age and causes deterioration in thinking skills, speech, and coordination.

What is a sclerotic lesion?

The word lesion refers to an abnormal change in the structure of your bones. Sclerotic means that the lesions are slow-growing changes to your bone that happen very gradually over time. Most of the time, sclerotic lesions are benign.

What could lucency mean on a Xray?

What can cause lucency of the bones?

According to the University of Washington School of Medicine, bone lucencies can be caused by a variety of factors, such as cysts, cancer, benign tumors or infection. Healio goes on to point out that fractures also cause bone lucencies.

What is ovoid lucency?

An ovoid is the 2-dimensional surface generated by rotating an oval curve about one of its axes of symmetry. The adjectives ovoidal and ovate mean having the characteristic of being an ovoid, and are often used as synonyms for “egg-shaped”.

What does a lucency area in a Xray mean?

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. An opacity indicates an area absorbing more radioactive energy than the surrounding tissue and will appear as lighter spots.
