Spiral CT is good for all kinds of organic lesions, especially parenchymal organ lesions. Including cranial system, respiratory system, digestive system, skeletal system and so on.
1. Respiratory system: spiral CT has good examination effect on all kinds of lung diseases, such as bronchodilatation, pneumonia, emphysema, tuberculosis, pulmonary nodular disease and so on. Especially enhanced CT is of great significance for the diagnosis and staging of lung cancer.
2. Cranio-cerebral system: Spiral CT can show well on cranio-cerebral trauma, intracranial hematoma, cerebral contusion, cerebral hemorrhage and other diseases, and also has certain diagnostic value on cranio-cerebral tumors, but the effect is not as good as that of nuclear magnetic resonance.
3. Digestive system: Spiral CT is better for the display of digestive system organs, which is important for acute pancreatitis, pancreatic cancer, liver tumors, etc. It can also be used to observe the morphology of digestive tract. It can also infer related diseases by observing morphological changes in the digestive tract, such as gastric cancer, gastric ulcer, colorectal cancer, colonic diverticulum, etc., but the effect is not as good as endoscopy, and biopsies can not be taken for pathologic examination.
4. Skeletal system: Spiral CT is more effective in showing the skeletal system, and it can find the small fractures that are not easy to be found by X-ray, such as those around the joints, spine, pelvis, etc. It can also find the herniated discs. It can also detect signs of herniated discs. However, CT does not have the same resolution for soft tissue as MRI.
Spiral CT is one of the most widely used examination modalities in the clinic, and it is recommended that patients choose the appropriate means of examination after consulting with a medical professional in relation to their condition.
