Magnetic Resonance Imaging (MRI) and Computed Tomography Scan (CT)

Modern medical technology allows physicians to capture detailed images of the body for diagnosing and treatment planning of various health issues. Radiologists use imaging technologies to diagnose or treat diseases. Interventional radiology is the performance of medical procedures with the guidance of imaging technologies. Acquisition of medical imaging is usually performed by a radiologic technologist and the results are interpreted by Radiologists, medical doctors that specialize in radiology. While Magnetic Resonance Imaging (MRI) and Computed Tomography Scan (CT) are useful for diagnosing and treating illnesses, each has their own health risks and benefits.

MRI and CT scans produce exact images of the body and can be used to guide treatment to the appropriate area without compromising other areas of the body. Radiation therapy also known as interventional radiology is a minimally invasive procedure performed using image guidance to pinpoint the exact location requiring treatment. Imaging is used for guidance of biopsies and other surgical procedures. Needle guidance by imaging allows for exact placement of a needle used for procedures such as abscess drainages and minimally invasive tumor treatments. MRI and CT images are used to monitor treatment results for various injuries, cardiac disease, and stroke. Mapping and planning using the images from MRI or CT scans are used for surgical procedures to ensure accuracy of the surgical instrument placement.

Magnetic Resonance Imaging and Computed Tomography Scans are not without risks to the patient and sometimes even the medical staff involved in the acquisition of the images. CT imaging uses X-rays in conjunction with computing (algorithms) to image the body in a ring-shaped apparatus that rotates around the patient producing a computer-generated cross-sectional image. CT exposes the patient to more ionizing radiation that regular radiograph (X-ray) or than using an MRI. CT scans expose patients to ionizing radiation which has been linked with possible risk of cancer development. The risk of continued
