概括

计算机断层血管学揭示了7个月的狗的腹腔血管生长. 血管大小和比率在7个月后稳定,但根据体重而异,影响年轻或大型狗的诊断标准.

科学领域:

兽医辐射学兽医辐射学
比较解剖学的比较.
医疗成像医学成像

背景情况:

计算机断层扫描 (CT) 对狗腹部血管的表征没有得到充分的记录.
了解主要腹血管的正常生长和尺寸变化对于准确的诊断解释至关重要.

研究的目的:

在成长中的狗中使用CT血管造影来评估大动脉 (Ao),尾腔静脉 (CVC) 和门静脉 (PV) 的生长和维度演变.
为了确定年龄和重量对这些船只尺寸和船间比例的影响.
建立不同犬类年龄和体重组的腹腔血管的参考标准.

主要方法:

这是一项回顾性研究,分析了32只狗的CT血管学扫描 (6只 beagles,26只混合品种).
测量包括Ao,CVC,PV的直径,Ao,L2脊椎的长度以及各种比率 (CVC/Ao,PV/Ao,Ao/L2,CVC/L2).
狗被按年龄 (4-24个月) 和体重 (<10公斤,10-30公斤,>30公斤) 分组;三名操作人员重复测量.

主要成果:

船舶直径 (Ao,CVC,PV) 和L2长度在7个月大时显著增加.
船舶间比率 (CVC/Ao,PV/Ao,Ao/L2,CVC/L2) 显示在7个月之前存在变化,随后稳定.
船舶尺寸和比例在重量组之间差异很大,但在每个组内保持稳定.

结论:

成人的血管标准不适合7个月以下的狗.
腹部血管结构的与年龄相关的变化需要特定年龄的参考范围.
血管大小的基于体重的变化需要对非常小或非常大的狗的测量进行谨慎的解释.

Imaging Studies for Cardiovascular System V: CT

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Abdominal Aorta

Abdominal Aorta

Once the aorta traverses the diaphragmatic plane at the aortic hiatus, it is known as the abdominal aorta. This anatomical structure is positioned leftward of the spinal column, encased within a cocoon of adipose tissue behind the peritoneal cavity. It terminates at the L4 vertebra, where it splits into the common iliac arteries. Prior to this bifurcation, the abdominal aorta gives rise to several vital branches.
The celiac trunk, a singular artery, divides into the left gastric artery, which...

Computed Tomography

Computed Tomography

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...
