What is an x-ray?
Conventional diagnostic radiology, also known as radiography, is most commonly known as x-ray. An x-ray is a picture of the inside of your child’s body. X-rays:
- use small doses of ionizing radiation to produce diagnostic pictures of the human body
- 是最古老，最常用的医学成像形式
- are fast and easy to obtain, making them particularly useful in emergency diagnoses

常见问题
What is conventional diagnostic radiology (X-ray)?
An x-ray is a picture taken of your child’s bones and organs by a large camera that uses radiation to take pictures of the inside of her body. The images are created when the x-ray passes through her bone and tissues onto a digital-image recording plate.
When is an x-ray needed?
X射线通常用于协助医师诊断和评估许多疾病，包括：
How should I prepare my child for an x-ray?
大多数X射线不需要特殊准备。除非您在预约时得到特定的说明，否则您的孩子可以像通常一样吃饭和喝酒。
这很有帮助：
- Give your child a simple explanation as to why she needs an x-ray.
- 向您的孩子保证您将在整个过程中都在那里。如果您怀孕了，则在拍摄X射线时将无法在您的孩子旁边。带另一个家庭成员或朋友与您的孩子在一起。
- 在等待时，请带上孩子最喜欢的书，玩具或安慰物体来占领她。
What should I expect when I bring my child to the hospital for an x-ray?
When you arrive, please go to the Radiology check-in desk.
- 患者体验代表将检查您的孩子并验证其注册信息。
- Your child may be asked to change into a gown for his or her examination.
- 您的孩子将需要去除任何可能掩盖图像的珠宝，眼镜和任何其他金属物体。
- 妇女应该告诉技术人员是否有可能怀孕。
X射线期间会发生什么？
技术专家会将您和您的孩子带入X射线室。您的孩子始终醒着。技术专家将：
- ask you and your child some screening questions
- position your child on the x-ray table and place the digital recording plate under the table in the area of the body being imaged
- use pillows or other positioning devices to help your child maintain the proper position
- place a lead apron over your child’s pelvic area or breasts when possible to protect him/her from radiation
The x-ray will be taken by a large camera. The technologist will operate the x-ray machine from behind a wall in the room. Often, more than one x-ray is taken.
- Your child will be asked to sit, stand, or lie very still while the x-ray is being taken.
- Your child may be asked to hold her breath for a few seconds while the x-ray is taken.
每次X射线所需的时间长度取决于为您的孩子订购的X射线类型。典型的X射线定位大约需要10分钟，而实际的X射线曝光需要不到一秒钟。
我的孩子会感觉到什么吗？
There is no pain associated with having an x-ray. Your child may need to remain in an uncomfortable position for a short time while the x-ray is taken, but that discomfort is brief.
X射线的风险是什么？
The benefit of an accurate diagnosis far outweighs the exposure to radiation that occurs during an x-ray. Because children are more sensitive to radiation exposure than adults, Boston Children’s Hospital specialists have been leaders in adjusting equipment and procedures to deliver the lowest possible dose to young patients.
X射线后会发生什么？
When the x-ray is done, your child will be ready to go home or see her doctor if an appointment is scheduled. One of the radiologists will review your child’s images and create a written report of the findings and diagnosis.
How do I learn the results?
放射科医生将向订购您孩子的X射线检查的医生提供报告。然后，医生将与您讨论结果。
