CT Scan Overview

 Computed tomography (CT scan or CAT scan) is a noninvasive diagnostic imaging method that is used to analyze and inspect interior body structures, anatomical structures, and detect diseases or ailments. The technology uses 3D imaging modalities to generate richer images that may be used to assess defects and malformations in any part of the body.  It generates horizontal and axial images of the body using a combination of X-rays and computer technology.

While a normal X-ray can provide a lot of information, it might be difficult to find specific data about internal organs and other structures. A CT scan provides more information than a normal X-ray. It can display detailed images of blood vessels, bones, fat, muscles, and organs in any part of the body.

The X-ray beam of a CT scan travels in circles around the body. This captures multiple perspectives of the same organ or structure. The X-ray data is redirected to a computer, which analyzes the data and displays it as a three-dimensional image.

In the case of contrast-enhanced CT scans may need you to fast for a period of time before the procedure.

CT scan vs. MRI

  CT scans are more widely used than MRIs and are typically less expensive. MRIs, however, are thought to be superior in regards to the detail of the image. The most notable difference is that CT scans use X-rays while MRIs do not. Other differences between MRI and CT scans include their risks and benefits: Risks Both CT scans and MRIs pose some risks when used. The risks are based on the type of imaging as well as how the imaging is performed. CT scan risks include: harm to unborn babies variable dose of ionizing radiation based on specific scan performed a potential reaction to the use of dyes MRI risks include: possible reactions to metals due to magnets loud noises from the machine causing hearing issues increase in body temperature during long MRIs claustrophobia click here You should consult a doctor prior to an MRI if you have implants including: artificial joints eye implants an IUD a  pacemaker

What are medical x-rays?

Image
click here X-rays  are a form of electromagnetic  radiation , similar to visible light. Unlike light, however, x-rays have higher energy and can pass through most objects, including the body. Medical x-rays are used to generate images of tissues and structures inside the body. If x-rays traveling through the body also pass through an x-ray detector on the other side of the patient, an image will be formed that represents the “shadows” formed by the objects inside of the body. One type of x-ray detector is photographic film, but there are many other types of detectors that are used to produce digital images. The x-ray images that result from this process are called radiographs.
