概括
中囊 (MCs) 在狗中很少见,在本研究中发现的患病率为5.66%. 这些所谓的中囊 (PMCs) 通常是小的,圆的,充满液体的,位于中中.
科学领域:
- 兽医辐射学 兽医辐射学
- 比较病理学比较病理学
背景情况:
- 中囊 (MCs) 是不常见的病变,起源于中中胚胎残留物.
- 虽然在狗和猫身上经常是偶然的发现,但MCs可以呈现为质量.
- 计算机断层扫描 (CT) 对狗的MCs描述很少.
研究的目的:
- 为了确定狗中可能存在的中囊 (PMCs) 的患病率.
- 为了描述狗中PMCs的CT成像特征.
主要方法:
- 追溯,单中心,描述性流行率研究.
- 包括866只狗的胸部CT扫描 (2019年1月-2021年8月).
- 评估PMC的存在,数量,位置,边缘,形状,体积,尺寸,质量效应和减弱值,由多名兽医放射科医生进行.
主要成果:
- 在866只狗中,在49只狗中发现PMC的流行率为5.66%.
- PMCs主要是圆形的,小的,单独的,充满液体的,位于头骨中枢中.
- 标志性特征包括明确的边缘,均的衰减和没有对比度增强,对比度前衰减的中位数为6.32 HU,中位数体积为1.19 cm3.
结论:
- 这项研究确定了在被研究的犬种群中,假定中囊的患病率为5.66%.
- 图像特征表明,PMC通常是偶然的,明确的,充满液体的病变.
- 这些发现支持在对具有这些特定CT发现的狗进行差异诊断时考虑偶然的PMC.

Computed Tomography
4.5K
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
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...

Imaging Studies for Cardiovascular System III: X-Ray
188
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Pneumothorax-II
153
Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.
