概括

声波辐射力冲动 (ARFI) 弹性图显示,与其他病变相比,狗肺部脱膜症的刚度较低. 这种技术可以补充成像用于诊断犬类肺部疾病.

科学领域:

兽医辐射学兽医辐射学
诊断成像诊断成像诊断成像
生物医学工程生物医学工程

背景情况:

狗的肺部病变需要准确的诊断工具.
声波辐射力脉冲 (ARFI) 弹性图形提供了一种非侵入性方法来评估组织硬度.

研究的目的:

评估ARFI弹性学在特征犬肺病变中的有效性.
为了区分各种类型的肺病理,包括巩固,,结节和质量.

主要方法:

对26只患有35个肺病变的狗进行了回顾性研究 (2020-2022年).
损伤评估包括放射学,B模式超声波和ARFI弹性学 (定性和定量剪切波速度-SWV).
病变根据临床,成像和组织病理/细胞学数据进行分类.

主要成果:

定量ARFI弹性学表明,与巩固 (2.94 ± 0.64 m/s),结节 (2.85 ± 1.40 m/s) 和质量 (3.13 ± 1.45 m/s) 相比,无弹性病变 (1.48 ± 0.35 m/s) 的刚度明显较低.
由于数量有限的良性病变,无法确定恶性瘤的确定的诊断截止值.
根据ARFI的弹性图表,可以根据硬度来区分病变类型.

结论:

ARFI弹性图是一种有前途的补充工具,用于评估犬肺病变.
需要对更大的样本大小进行进一步的研究,特别是对良性病变进行进一步的研究,以充分探索弹性图形学在预测恶性瘤方面的潜力.

Physical Assessment of the Respiratory Tract II: Palpation

Physical Assessment of the Respiratory Tract II: Palpation

Physical assessment of the respiratory tract is critical in identifying potential health issues. One key component of this assessment is palpation, a technique healthcare providers use to assess the body for abnormalities. This content explores the method of palpation in evaluating the respiratory tract, focusing on thoracic palpation and tactile fremitus.
Thoracic Palpation
Thoracic palpation detects tenderness, masses, lesions, respiratory excursions, and vocal fremitus. The nurse assesses...

Respiratory System Abnormal Finding II: Palpation and Auscultation

In assessing respiratory abnormalities, palpation and auscultation are critical tools for detecting and interpreting various pathophysiological changes. These techniques provide insight into underlying disorders by evaluating tactile sensations and sounds produced by the respiratory system.
Palpation Findings
During a respiratory assessment, palpation can reveal several vital abnormalities:

Assessment of Respiration

Assessment of Respiration

The respiratory system's basic structures and primary functions lay the foundation for nurses' comprehensive respiratory assessments. This assessment includes subjective and objective data to gauge the patient's respiratory health.
Subjective Assessment: Nurses interview the patient to gather information directly during the subjective assessment. It includes questions about the individual's medical history, medications, and symptoms, focusing on past respiratory conditions like...
