CT scanning of the abdomen/pelvis is typically used to help diagnose the cause of abdominal pain and diseases of the bowel and colon, and also performed to visualize the liver, spleen, pancreas and kidneys.
CT imaging can also play a significant role in the detection, diagnosis and treatment of vascular disorders that can lead to stroke, gangrene or kidney failure.
CT of the chest is used to: further examine abnormalities found on conventional chest x-rays, help diagnose clinical signs or symptoms of disease of the chest, detect and evaluate the extent of tumors that arise in the lung and mediastinum, or tumors that have spread there from other parts of the body, assess whether tumors are responding to treatment
help plan radiotherapy, screen for lung cancer or other lung disorders.
A CT angiogram (CTA) may be performed to evaluate the blood vessels (arteries and veins) in the chest. This involves injecting the iodine into a vein a little faster, and also, more numerous and thinner slices are obtained through the chest in order to see the arteries to better advantage.
CT scanning of the head is typically used to detect bleeding, brain damage, skull fractures, aneurysms, blood clots, tumors, enlarged brain cavities, diseases, fractures or malformations of the skull, inflammation of sinuses, and to evaluate the extent of bone and soft tissue damage.
CT scanning of the spine is also performed to evaluate the spine, detect tumors, help diagnose spinal pain, and measure bone density.
Low Dose CT – Lung Cancer Screening – This test consists of a low dose, non-contrast CT that uses X-rays to scan the entire chest in about 5-10 seconds. This test is able to detect lung cancer in its earliest stages.
