CT Scan, Computerized Tomography, or Computerized X-ray is the examination for physical abnormality by using x-ray. The ray is cross-sectionally projected through the targeted organ. Then, computer processing is used to create images. CT Scan provides a cross-sectional image of the organ for detailed diagnosis. Apart from offering 3D images, the CT Scan can also create tens of cross-sectional slices of the organ – enabling the doctors to read the abnormality of the organ with more precision and details than the general x-ray. As the traditional x-ray only creates 2D images with length and width. No image depth can be identified and only the overall image of the organ is generated. These are the limitations of general x-ray machines when comparing to computerized x-ray, in which the more advanced sensoring technologies are applied.

Benefits of CT Scan

With the ability to create images that combine tissues, bones, and vascular systems, CT Scan is essential for diagnosis. Doctors will be able to get great details of almost all body parts from head to toes. The equipment can detect cardiovascular diseases, bone diseases, traumatic injuries, and metastatic cancer.

CT Scan examination is categorised into 4 systems:

• Brain system
• Abdominal and thoracic cavity systems
• Musculoskeletal system
• Vascular system

Objectives of CT Scan

• Examine organ tumors, including their location and size.
• Detect tumor metastasis towards adjacent lymph nodes.
• Examine cerebral, abdominal, and pelvic congestions.
• Detect vascular abnormalities such as aneurysm, thrombosis, etc.
• Detect abnormality in bone and joint such as fracture, dislocation, or inflammation.

Benefits of CT Scan Machine

• Provides cross-sectional tomographic images, offering better organ details and structure than a general x-ray examination. These can be used to create 3D and other plane images. 
• Fast procedure enables doctors to diagnose patients with a tremble, agitation, or uncooperative.
• Great for examining dynamic organs such as abdominal and thoracic cavities.
• Great for patients with signs of acute hemorrhage or trauma.
  

Cautions when Using CT Scan Machine

• Radiation exposure, especially in children and pregnant patients
• High risk for radiocontrast media hypersensitivity, particulary in elderly and patients with kidney and heart diseases.
• Difficulties in differentiating soft tissues with similar density could lead to unclear results.
