医学成像医学成像
生物机械分析分析

背景情况:

德乔尔分类是三角膜发育不良症的标准,但由于主观标准和放射性挑战,它存在局限性.
准确地评估三气形态对于了解形状的不稳定性至关重要.

研究的目的:

开发和验证一种定量方法,用3DCT重建来评估三膜发育不良.
为客观测量三角膜形态而引入基于跨状轴 (TEA) 的新参数.

主要方法:

60名患者 (20人患有三角膜发育不良,40人为对照组) 接受了3DCT重建.
在八个平面 (0-105°) 测量了六个参数,相对于TEA和中间表皮 (MEC).
测量包括距离侧峰 (LP),中峰 (MP) 和三沟 (TG) 的距离.

主要成果:

与对照组相比,患有三角膜发育不良的患者在0°-30°时显示出显著更高的TG-TEA和MP-MEC值 (p <0.05).
对LP-MEC,MP-MEC和TG-TEA的特异性差异在A,B和D类型的发育不良症中被观察到.
3D CT 方法证明了在量化三细胞形态方面具有可重复性.

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...

Cranial Bones: Lateral View

Cranial Bones: Lateral View

The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Imaging Studies III: Computed Tomography

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...
