(CT) scanning is a rapid, painless diagnostic examination that combines
X-rays and computers. A CT scan allows the radiologist to see the
location, nature, and extent of many different diseases or abnormalities
inside your body.
Our computerized CT scanners incorporate all
recent and dramatic advances and are capable of
ultra rapid scanning and helical imaging, a combination
that allows an examination of the abdomen to be
completed in seconds. The high-resolution images
this system produces reveal unsurpassed details,
and computers allow Princeton Radiology radiologists
to manipulate and reconstruct images in multiple
planes, extrapolating 3-dimensional images from
the original data. This enables physicians to
visualize vessels and organs similar to "virtual
We offer low-dose 128- and 64-Slice CT scans for specified imaging studies.
We establish our scanning protocols based on age, weight, body type and area of interest to reduce radiation dose as low as possible. This approach applies to everyone including both children and adults. We practice ALARA – As Low As Reasonably Achievable – to maintain high image quality, while minimizing radiation exposure.
What will the exam be like?
You will lie comfortably on the CT exam table. The table will move slowly into the CT scanner. The X-ray tube will move around as it captures images. Depending on the exam, a contrast material may be used to enhance the visibilty of certain tissues or blood vessels. The contrast material may be injected directly into the bloodstream, swallowed, or administered by enema. The contrast material will be naturally eliminated within a few hours to a day or two depedning on the area examined and the type of contrast material used. A CT scan usually takes 15 to 30 minutes.
