Computed Tomography (CT)

What is CT?

The term “computed tomography”, or CT, refers to a computerized X-ray imaging procedure in which a narrow beam of X-rays is aimed at a patient and quickly rotated around the body, producing signals that are processed by the machine’s computer to generate cross-sectional images—or “slices”—of the body. These slices are called tomographic images and contain more detailed information than conventional X-rays. Once a number of successive slices are collected by the machine’s computer, they can be digitally “stacked” together to form a three-dimensional image of the patient that allows for easier identification and location of basic structures as well as possible tumors or abnormalities.[i]

CT scans can be used to identify disease or injury within various regions of the body. For example, CT has become a useful screening tool for detecting possible tumors or lesions within the abdomen. A CT scan of the heart may be ordered when various types of heart disease or abnormalities are suspected. CT can also be used to image the head in order to locate injuries, tumors, clots leading to stroke, hemorrhage, and other conditions. It can image the lungs in order to reveal the presence of tumors, pulmonary embolisms (blood clots), excess fluid, and other conditions such as emphysema or pneumonia. A CT scan is particularly useful when imaging complex bone fractures, severely eroded joints, or bone tumors since it usually produces more detail than would be possible with a conventional X-ray.[ii]

What is the right technology?

There are endless considerations when it comes to making a technology decision for CT. What slice count is necessary for achieving your clinical goals? What type of injector should you get? What dose optimizations features are needed to maximize patient safety? Do you need a wide-bore gantry for your patient population?

Shared Imaging provides CT technology from all the OEMs, and can customize software package, accessories (i.e. injectors) and slice count to match your clinical needs. Whether you are looking for the latest in technology, or simply a reliable workhorse system, Shared Imaging can provide you the system you need to best serve your patient population. We offer new, used and refurbished systems in multiple environments, including in-house, modular and mobile, ensuring you get the right technology at the right time in the right place for the right cost.

What does your ideal CT solution look like?

Do you need the latest in technology or simply a reliable system to handle bread & butter procedures? Are you going to place the system in-house or place the system in a medical coach? What are your procurement options; is capital available? How about your staffing needs; self-staff or not?

There are plenty of questions to consider in developing your ideal CT solution. Our goal is to enable you to customize a solution that answers every one of these questions exactly as needed, and then exceed expectations in its delivery.
