For more than three decades, CT has been an important diagnostic imaging tool. Since its introduction in the early 1970s, CT has become an invaluable tool in diagnostic imaging. The number of CT examinations has risen dramatically over the past 20 years. There are potentially 260 million CT examinations performed annually worldwide. In the year 2003, 21,964 CT examinations were performed in our Radiology Department in Cairo University.

Since its introduction in the late 1970's, CT has made spectacular technological advancements that dramatically improved the detection and characterization of a wide variety of pathology.

CT technical advancement:

During a CT examination, the individual lies on a bed (table) that moves through a gantry that contains the x-ray source opposite (180 degree) the x-ray detectors. the gantry continuously rotates around the patient while the table moves through the gantry. The images are formed based on the character (energy and amount) of the x-ray beam that strides the detectors after it passes through the individual. the character is affected by the various organs and structures through which it passes. I n the early 1990s , there was a great leap forward in CT: SLIP ring technology. It freed the gantry to rotate continuously, unimpeded by wires. This leap was called helical (or spiral) CT; the term basically represents a tracing of the spiral path of the z-ray beam along the patient due to the gantry rotating continuously while the table (and the patient) moved through the gantry. In addition, the x-ray detectors have continued to evolve. In 1998, the detector technology again moved forward so that multiple rows of detectors could simultaneously capture and convert x-rays. This advancement is called multi-slice or multi-detector CT. over the past 5 years, the number of the detector rows has increased from 4 to 16 and recently 32 slice MDCT. One benefit of this wider beam is that the patient can now travel through the x-ray scanner quicker.

Faster scanning has several benefits. It reduces the use of resources required for pediatric sedation, a great savings in cost. this is one reason that , in children MDCT is being performed more frequently than MR for similar applications. faster imaging also decreases motion artifact, particularly in patient that have limited breath-hold ability during scanning. faster scanning has also been applied to freeze periodic motion such as that with the heart for cardiac and coronary artery evaluation.

In addition to the r\traditions CT applications new applications, over the past 5 years, include CT angiography (CTA) of cardiac and vascular structures, screening CT for coronary artery disease, evaluation of pulmonary embolism, urologic assessment, assessment of bowel, 3 D reconstruction, and virtual endoscopies (bronchoscopy and colonoscopy).
