Which statement about CBCT is inaccurate?

CBCT provides three-dimensional imaging by rotating a cone-shaped X-ray beam around the patient and reconstructing a volumetric dataset, which makes 3D visualization possible and is a core reason it’s valued in dental imaging. It uses cone-beam geometry and is designed to capture detailed hard tissues like teeth and bone, which is why those first two statements fit well. The statement about soft tissues being completely invisible is inaccurate. Although CBCT is optimized for hard tissues and has limited soft-tissue contrast compared with CT or MRI, it can still show soft-tissue outlines and structures (such as airways, swelling, and certain soft-tissue landmarks). The main limitation is not a total inability to visualize soft tissues, but rather poor soft-tissue contrast and higher susceptibility to artifacts, which makes soft-tissue detail less reliable.
