Computed Tomography (CT)
What is an X-ray?
The most frequently used diagnostic tool, images are created by passing controlled amounts of radiation through the body and capturing the resulting shadows on a digital image receptor.
Who Should NOT Have an X-ray Exam?
If you are pregnant or may be pregnant, consult your physician prior to the exam.
What Should I Expect During an X-ray Exam?
Your position, standing or lying down, will be determined based upon the type of X-ray exam being performed. You may be asked to hold your breath and remain still for a few moments.
What is a CT Scan?
Combining X-ray with advanced computer processing technology, detailed images of internal organs, tissue, bone and blood vessels are captured for evaluation.
Who Should NOT Have a CT Exam?
If you are pregnant or may be pregnant, consult your physician prior to the exam. Due to the possible use of a contrast agent, be sure to also inform your physician or the technologist if you have any allergies, especially to iodine or shellfish.
What Should I Expect During a CT Exam?
CT exams are quick and comfortable. Your exam may require that a contrast agent be given intravenously which will make your blood vessels and tissues more visible. You will then be asked to lie still on a table as it gently moves you through the scanner. You may also be asked to hold your breath for a few moments during the exam, as any movement may blur the image.
What is an Ultrasound?
Through the use of sound waves, movement of internal tissues and organs as well as blood flow can be seen as a visual image when the reflected sound wave echoes are recorded.
Who Should NOT Have an Ultrasound?
Consult your physician prior to the exam for any concerns.
What Should I Expect During an Ultrasound?
Depending on the type of ultrasound, you may be required to not eat for 4-6 hours before the exam OR drink up to 6 glasses of water 2 hours prior to your exam and avoid urinating. You will be asked to lie on a table while the technologist spreads a clear, warm gel on your body in the area to be examined. A transducer (instrument that creates sound waves) is then pressed against your body and moved until the desired images are captured.
