Radiology

The medical specialty that uses medical imaging to diagnose and treat diseases within the body.

 

X-ray:

A form of electromagnetic radiation used in imaging to visualize the internal structures of the body.

 

CT Scan (Computed Tomography):

A medical imaging technique that uses X-rays and computer processing to create detailed cross-sectional images of the body.

 

MRI (Magnetic Resonance Imaging):

An imaging technique that uses strong magnetic fields and radio waves to generate detailed images of the internal structures of the body.

 

Ultrasound:

Imaging using high-frequency sound waves to create images of structures within the body, commonly used in obstetrics and assessing soft tissues.

 

Fluoroscopy:

Real-time imaging technique that uses X-rays to obtain moving images of the internal structures of the body, often used in procedures like angiography.

 

PACS (Picture Archiving and Communication System):

Digital storage and retrieval system for medical images, allowing healthcare professionals to access and manage images electronically.

 

Radiopaque:

Substances that do not allow X-rays to pass through, often used as contrast agents to enhance visibility of certain structures during imaging.

Contrast Agent:

Substances, such as iodine or gadolinium, introduced into the body to enhance the visibility of specific tissues or blood vessels during imaging.

 

Radiation Dose:

The amount of ionizing radiation absorbed by the body during a medical imaging procedure, with efforts to minimize exposure for patient safety.

 

Radiologist:

A medical doctor specialized in interpreting medical images and providing diagnostic information to other healthcare professionals.

 

Nuclear Medicine:

A branch of radiology that uses small amounts of radioactive materials to diagnose and treat diseases.

 

Mammography:

X-ray imaging of the breast, commonly used for breast cancer screening.

 

Interventional Radiology:

A subspecialty of radiology that uses imaging guidance to perform minimally invasive procedures for diagnostic and therapeutic purposes.
