概括
圆束计算断层扫描 (CBCT) 提供了比2D周围放射图更详细的对无症状持续性内牙病变 (APEL) 的评估. CBCT改善了检测损伤大小,结构的接近,以及错过的通道,以便更好地规划内牙治疗.
科学领域:
- 牙周内脏病学 牙周内脏病学
- 牙科放射学 牙科放射学
- 口腔和大面部成像技术
背景情况:
- 无症状的持续性内牙病变 (APEL) 需要精确的放射评估,以有效管理.
- 传统的2D周周 (PA) 放射可能在评估病变特征和接近关键解剖结构时存在局限性.
研究的目的:
- 为了比较2DPA放射和3D圆束计算断层扫描 (CBCT) 的诊断能力,以评估APEL.
- 用两种成像方式来评估病变大小,接近解剖结构,并检测错过的通道.
- 开发一个放射性协议,用于管理无症状的持续性内牙病变.
主要方法:
- 一项前性队列研究,涉及82名APEL在77名患者.
- 由两个校准的内牙科医生对2DPA放射和有限视野CBCT扫描进行评估.
- 计算病变大小,接近结构和检测错过的通道的病变间协议 (kappa).
主要成果:
- 与PA放射图相比,CBCT通常显示出较大的病变大小,特别是在后牙.
- CBCT在评估靠近大鼻腔和神经血管结构时表现出更高的确定性.
- 与PA放射图相比,CBCT在识别潜在的遗漏通道方面更有效.
结论:
- CBCT提供了比PA放射图更全面的APEL评估.
- 推CBCT用于监测APEL,特别是在后牙,以及在PA放射图解不确定的前牙.

01:24X-ray Imaging
German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with X-rays, and by 1900, X-ray was widely...

Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and the...

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...
