超低剂量圆束计算机断层扫描 (CBCT) 提供足够的图像质量来诊断鼻腔疾病,并有助于手术规划. 这种超低剂量 (ULD) CBCT 推用于患有慢性鼻腔症状的患者,尽管广泛的疾病可能需要额外的成像.
科学领域:
- 放射学 放射学是一门学科.
- 耳鼻喉科 耳鼻喉科 耳鼻喉科
- 医疗成像医学成像
背景情况:
- 评估临床图像质量 (IQ) 和鼻腔超低剂量 (ULD) 圆束计算断层扫描 (CBCT) 的可用性.
- 将ULD CBCT与高分辨率 (HR) CBCT进行比较,以确定协议的优缺点.
研究的目的:
- 评估ULD CBCT用于鼻腔成像的诊断和手术规划实用性.
- 确定ULD CBCT在不同程度的鼻腔阴暗化中的疗效.
主要方法:
- 33名受试者的66个解剖部位使用HR CBCT和ULD CBCT两种方式进行成像.
- 图像质量,不透明度,阻塞,结构特征和操作可用性都被系统地评估.
主要成果:
- 在没有或轻微不透明的受试者中,整体智商优异 (100% HR CBCT,99% ULD CBCT足够).
- 增加的模糊化降低了两种模式的图像质量.
- 在 ULD CBCT 证明了足够的质量,用于手术规划,在皮切除术,额头鼻腔切除术,形切除术和后部切除术中.
结论:
- 副鼻腔ULD CBCT的图像质量足以用于临床诊断和手术规划.
- 建议ULD CBCT作为患有复发性或慢性鼻腔症状的患者的主要成像方案.
- 考虑对患有广泛的慢性鼻炎或额头鼻干扰的患者进行额外或常规成像.

The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
