Most expansile, lucent lesions are located in the medullary space of the bone. However, we can further define the location of the lesion by noting its relationship to the physis. Many lesions tend to occur in a “favorite” part of the bone.

Apr 17, 2024 · Mnemonics for the differential diagnosis of lucent/lytic bone lesions include: FEGNOMASHIC. FOG MACHINES. They are anagrams of each other and therefore include the same components. They are by no means exhaustive lists, but are a good start for remembering a differential for a lucent/lytic bone lesion and will suffice for >95% of the time 1.
Apr 2, 2024 · A bone scan is a test that uses nuclear imaging to help diagnose and track several types of bone disease. Nuclear imaging involves using small amounts of radioactive substances, called radioactive tracers, a special camera that can detect the radioactivity and a computer.
Feb 8, 2023 · Less dense areas appear darker on the image and can be described as lucent, having increased lucency or being radiolucent. What’s the difference between density and lucency? Density and lucency are descriptions of how the soft tissues and structures inside your body absorb X-ray beams.
