概括
在骨肉瘤患者的CT扫描中,不确定的肺结节是常见的,但不能预测转移. 然而,在监测期间发现的结节与疾病进展相关,其大小和数量是关键因素.
科学领域:
- 在瘤学瘤学.
- 放射学 放射学是一门学科.
- 肺部医学 肺部医学
背景情况:
- 骨肉瘤经常转移到肺部,需要通过胸部CT扫描进行监测.
- 在CT扫描中发现的肺结节可能是不确定的,缺乏明显的转移意义.
- 骨肉瘤患者未确定的结节的自然史和预测因素尚未明确.
研究的目的:
- 为了调查骨肉瘤患者无确定的肺结节的自然史.

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...
