锥形束计算机断层扫描

Cone-Beam Computed Tomography

A medical imaging technique that uses a cone-shaped X-ray beam and digital detection to produce high-resolution, cross-sectional images of the teeth, jaws, and surrounding structures. / 一种利用锥形X射线束和数字探测器产生牙齿、颌骨及周围结构高分辨率横断面图像的医疗成像技术。

Sub-knowledge points

Conventional CBCT based on morphological descriptors (shape, borders, volume).Radiomic approaches achieving areas under the curve (AUC) ranging from 76% to 86.4%.

Higher-order knowledge points

Differential diagnosis between radicular cysts and periapical granulomas.Preoperative distinction of lesions.

Main parameters and performance indicators

Radiomic texture analysis: Image analysis method using quantitative features extracted from radiological images.Weighted sequences (T1w, T1wFS, T2wFS): MRI pulse sequences for tissue contrast enhancement.

Open problems

Multicenter standardization of technical parameters and imaging analysis protocols is necessary.Clinical applicability remains partial; definitive differentiation between true apical cysts and pocket cysts still requires histopathological confirmation.
