CT Scanning

CT Scanning

Anna Jaques obtains diagnostic images with the GE 64 Slice Lightspeed Computed Tomography (CT) Scanning system. This scanner allows doctors to simultaneously view multiple, wafer-thin images of a patient's, spine, head, chest, abdomen and pelvis without requiring any kind of invasive procedure. This results in high-resolution images that aid in more accurate diagnoses of patients than was previously possible.

Radiological services for CT Scans are available at: 

Anna Jaques Hospital

Test Overview

A computed tomography (CT) scan uses x-rays to produce detailed pictures of structures inside the body. A CT scan is also called a computerized axial tomography (CAT) scan.

A CT scanner directs a series of X-ray pulses through the body. Each x-ray pulse lasts only a fraction of a second and represents a "slice" of the organ or area being studied. The slices or pictures are recorded on a computer and can be saved for further study or printed out as photographs.

Dense tissues, such as bones, appear white in the pictures produced by a CT scan. Less dense tissues, such as brain tissue or muscles, appear in shades of gray. Fluid-filled spaces, such as the openings in the brain (ventricles), appear dark gray. Air-filled spaces, such as the facial sinus cavities, appear black.
