CT and MRI

Introduction

CD or coronary disease refers to a complex disease which causes absent or reduced flow in blood in arteries of the heart one or can be more, which surround the heart supply. The disease might be diffuse or focal. Beside from uncommon birth defects (congenital anomalies), CD is commonly a disease which is degenerative, and not very much common as clinical problem since a person reaches the age of 30, however the diseases is common among people older than 60 years. Two in every eight people will have a heart-attack. The initial symptom of the recognition might be death. Crown is the word from where the term coronary is derived, which refers to the way these arteries are place on different position of the heart. An early diagnose is vital for the prevention of this diseases and will aid in the giving the proper care to the patient. This is necessary to contain in the beginning stages as it can develop complications like death and cardiac arrest. However, for the identification of Coronary diseases CT scan and MRI methods are used, however, lack of evidences are available regarding the comparison of these tetchiness.

Aims and Objectives

The aim of this paper is to compare the accuracy of MRI and CT scan in diagnosing the coronary disease. This research project will critically review the results of both CT scans and MRI in identifying coronary diseases, and then assess the accuracy of the results through comparisons of the results obtained from both procedures.

Justification for the selection of topic

CT or Computed Tomography scans are the most preferred method by the patients for the diagnosis of various diseases because of the involvement of low cost. However, it has been observed that MRI produces a detail report and is more accurate in diagnosis of the disease. However, lack of availability of evidences in this regard prompted for the selection of the subject.

Literature Review

CT Scans

CT scans were first used during the 1970s and still remain the most widely available and convenient tools for most clinical practice. Notably, they are also less expensive than the alternative, namely MRI. The CT scanner takes multiple X-ray pictures of the brain from a small device that rotates 360 degrees around the head. These multiple pictures are sent to a computer, which then reconstructs the pictures into a coherent image of the brain that can be viewed in various ways. Because these machines are widely available, CT scans are often used when brain imaging is needed in an emergency (Candinas and Boesiger, 2004).

Magnetic Resonance Imaging Advantages and Limitations

MRI scans became available during the 1980s. Rather than using radiation to take pictures of the body, MRI relies on extremely strong magnetic fields that cause atoms to align themselves in certain directions. A second magnetic pulse then shifts the alignment of the atoms, and when that pulse ends the atoms return to their original alignment; this return causes them to emit a radiofrequency signal that is ...
