- 头部和部手术 头部和部手术
- 放射学 放射学是一门学科.
- 血管解剖学 血管解剖学
背景情况:
- 腹腹 (PTA) 是一种常见的深部感染,需要在关键的宫血管附近排水.
- 临床医生缺乏关于内动脉 (ICA),外动脉 (ECA) 和内静脉 (IJV) 与PTA的距离的定量数据.
- 血管并发症虽然很少见,但在床边排水过程中存在重大风险.
研究的目的:
- 描述基于对比增强计算机断层扫描 (CT) 的工作流程,用于评估与PTA相关的血管解剖学.
- 量化PTA与ipsilateral ICA,ECA和IJV之间的距离.
- 用修改后的Pfeiffer系统来分类针排水期间ICA损伤的理论风险.
主要方法:
- 一个追溯的队列,包括94名单边PTA的成年患者.
- 增强对比度的CT获取可视化PTA和宫血管.
- 测量从囊到ICA,ECA和IJV的线性距离,与相反的侧面相比.
主要成果:

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...

Computed Tomography
8.1K
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...

Observational Studies
10.7K
Observational studies are a type of analytical study where researchers observe events without any interventions. In other words, the researcher does not influence the response variable or the experiment's outcome.
There are three types of observational studies – Prospective, retrospective, and cross-sectional.
Prospective Study
Prospective studies, also known as longitudinal or cohort studies, are carried out by collecting future data from groups sharing similar characteristics. One...

Design Example: Analyzing Capacity Contours for Flood Risk Assessment
288
Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley. The engineers...

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

Naturalistic Observations
17.0K
If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...
