- 在瘤学瘤学.
- 病理学 病理学 病理学
背景情况:
- 头部和部软骨瘤 (HNCS) 是一种罕见的恶性瘤.
- 了解其多样化的成像特征对于准确诊断至关重要.
研究的目的:
- 为了研究HNCS的成像特征.
- 为了将成像发现与瘤起源和病理亚型相关联.
主要方法:
- 对13例病理诊断的HNCS病例 (2000-2022) 的回顾性审查.
- 根据原产地 (骨与软组织) 和亚型 (常规,介质,myxoid) 的分类.

01:10Computed 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...

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...
