CT成像
Computed tomography (CT) creates 3D images of bones, organs, soft tissue and blood vessels. CT扫描是一种快速扫描, painless way to get potentially life-saving information about injuries, 疾病或其他情况.
低剂量肺部CT is one of the only ways to detect lung cancer early, when it’s most treatable.
CT scans are also critical imaging tools to use during traumas because they don’t have the same restrictions as MRIs for people who have metal or certain implanted medical devices.
CT也是不可或缺的 PET / CT 技术. PET / CT creates images using radioactive tracers to highlight parts of the body, while CT records how the organ or system functions.
CT如何工作
CT relies on X-rays which are captured as the machine rotates around the body, creating “slices” called tomographic images. When the slices are stacked digitally, they form a 3D image. Each slice takes only a few seconds to record.
Radiologists and other specialists rotate the 3D image and view it slice by slice to find the exact spot where a medical problem occurs.
CT影像学评估情况
CT scans provide valuable information about many conditions, including:
- 脓肿
- Aneurysms in the aorta, chest, abdomen and other arteries
- 阑尾炎
- 血凝块
- 脑部损伤或颅骨骨折
- 癌症和肿瘤的位置
- 克罗恩氏病
- 骨折
- 心脏病
- 内脏损伤
- 内出血
- 肺栓塞
- 窦条件
- 骨骼结构
- 脊柱骨折和脊柱疼痛
- 中风
A technologist may administer contrast with an IV to highlight areas, such as the circulatory and digestive systems.
CT images are also helpful tools during some interventional radiology procedures, such as a biopsy or removing fluid from an abscess.
低剂量肺部CT
低剂量肺部CT筛查 provide hope for people who have risk factors for lung cancer. They are the only recommended screening for lung cancer and can detect it in the early, 大多数可治疗阶段. Lung CTs are scheduled based on a person’s age and smoking history.
准备CT检查
Some people may schedule a CT a month or a year out. Others may be sent the same day as an appointment with a healthcare provider.
In most cases, you will not have to take steps to prepare. Abdominal and pelvis CTs may require that you not eat or drink for four hours before the scan.
If you are scheduled to receive contrast to highlight CT areas, you may need to drink the iodine-based solution a couple of hours before your appointment. IV contrast is effective almost immediately, so that requires less prep time.
你的CT检查
You may be asked to change into a gown depending on the exam. We will also ask you to remove any jewelry, 眼镜, 假牙或发夹, so they don’t interfere with the image.
During a CT, you will lie on a table that moves into a tube. You may need to hold your breath while the machine snaps an image.
A CT without contrast can be done in 10 minutes. 对比色的需要更长的时间. Generally, a CT takes 10 to 30 minutes.
