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 have become very important standard medical imaging modalities due to advantages of having the capability to evaluate both anatomic and physiologic parameters produce noninvasive unique clinical information. MRI and CT imaging can be done in Three Dimensional (3D) views allowing detailed images in specific areas of the body that physicians can use to diagnose health conditions and diseases. The images that are produced are valuable in diagnosing a broad range of medical conditions. Chemical agents called contrast material can be used to enhance the images obtained by highlighting the specific target area in question. MRI and CT imaging is beneficial for patients and physicians, providing clarity and details about internal organs, bones, soft tissue and blood vessels, giving the ability to diagnose cancer, heart and vascular disease, and muscular and bone abnormalities. Effective images aid physicians in diagnosis and treatment and reduce the need for exploratory surgery. Imaging may eliminate the need to subject the patient to invasive surgical procedures in order to determine cause of illness. The images of soft-tissue structures are more likely to characterize diseases without using surgical biopsy. MRI and...
