Computed tomography defects

How can we reduce defect in CT scan images?
Noise can be reduced using iterative reconstruction or by combining data from multiple scans.
This enables lower radiation dose and higher resolution scans.
Metal artifacts can also be reduced using iterative reconstruction, resulting in a more accurate diagnosis..
What abnormalities and disorders can be detected using CT scans?
What can CT scans detect?
Certain types of cancer and benign (noncancerous) tumors.Fractures (broken bones).Heart disease.Blood clots.Bowel disorders (appendicitis, diverticulitis, blockages, Crohn's disease).Kidney stones.Brain injuries.Spinal cord injuries..
What abnormalities are they looking for in the CT scan?
This test may be used to look for:
Cause of blood in the urine.Cause of abdominal pain or swelling.Cause of abnormal blood test results such as liver or kidney problems.Hernia.Cause of a fever.Masses and tumors, including cancer.Infections or injury.Kidney stones..
What are the risks of a CT scan?
Radiation exposure
The low doses of radiation used in CT scans have not been shown to cause long-term harm, although at much higher doses, there may be a small increase in your potential risk of cancer.
CT scans have many benefits that outweigh any small potential risk..
Affected by:
Noise: higher noise = worse contrast differentiation.Tube current: lower tube current = more noise (see above)Inherent tissue properties: difference in linear atteunation coefficient of adjacent imaged objects determines contrast.Beam kilovoltage: higher beam energy generally reduces contrast.

Mandibular depression

The Stafne defect is a depression of the mandible, most commonly located on the lingual surface.
The Stafne defect is thought to be a normal anatomical variant, as the depression is created by ectopic salivary gland tissue associated with the submandibular gland and does not represent a pathologic lesion as such.
This cavity is commonly observed on panoramic radiograph.
