• Areas of radiolucency in the bone scan indicated possible fractures.
• The radiologist noted increased radiolucency in the patient’s dental X-rays.
• Air-filled spaces show high radiolucency on radiographic images.
• The tumor’s radiolucency helped distinguish it from surrounding dense tissue.
• Radiolucency varies depending on the density and composition of different body tissues.
