概括
先进的心脏MRI有效地表征了sarcoma患者的antracycline诱导的心脏毒性,与乳腺癌患者相比,揭示了明显的心脏变化. 这种成像技术有助于评估心脏健康状况,并在肉瘤治疗中分层风险.
科学领域:
- 心脏病学 心脏病学
- 在瘤学瘤学.
- 放射学 放射学是一门学科.
背景情况:
- 人环素是已知的心脏毒剂,对它们在肉瘤患者的心脏作用的研究有限.
- 心脏磁共振成像 (MRI) 为详细的心脏评估提供了先进的功能.
研究的目的:
- 通过使用心脏MRI,在肉瘤患者中表征抗环素诱导的心脏毒性.
- 将这些心脏变化与乳腺癌患者观察到的心脏变化进行比较.
主要方法:
- 患者在基线,治疗后和6个月的随访期间接受了心脏MRI.
- 评估的关键指标包括左心室 (LV) 质量,射出分数 (RVEF,LVEF),心肌应变,T1,T2和细胞外体积 (ECV).
主要成果:
- 肉瘤患者的LV质量增加和RVEF减少;LVEF保持在>50%.
- 肌心T2增加,而心肺内皮细胞在肉瘤中降低,与乳腺癌模式相反.

4.9K
Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
