Computerized tomography limitations

  • What are the advantages and limitations of CT scan?

    Benefits/Risks
    Additionally, the detailed images provided by CT scans may eliminate the need for exploratory surgery.
    Concerns about CT scans include the risks from exposure to ionizing radiation and possible reactions to the intravenous contrast agent, or dye, which may be used to improve visualization.May 1, 2023.

  • What are the problems with CT scans?

    Although rare, the contrast material can cause medical problems or allergic reactions.
    Most reactions are mild and result in a rash or itchiness.
    In rare instances, an allergic reaction can be serious, even life-threatening.
    Tell your doctor if you've ever had a reaction to contrast material..

  • A person who is very large may not fit into the opening of a conventional CT scanner.
    Or, they may be over the weight limit—usually 450 pounds—for the moving table.
    Spinal CT does not consistently show enough detail to properly assess the spinal cord.
  • Although rare, the contrast material can cause medical problems or allergic reactions.
    Most reactions are mild and result in a rash or itchiness.
    In rare instances, an allergic reaction can be serious, even life-threatening.
    Tell your doctor if you've ever had a reaction to contrast material.
  • CT scans use X-rays, which produce ionizing radiation.
    Research shows that this kind of radiation may damage your DNA and lead to cancer.
Because findings from CT are so comprehensive, physicians sometimes allow themselves to be misled by a negative report, believing that more definitive testing  DrawbacksLimitationsWhat Should Be Done?
