WebJan 1, 1999 · The radiation dose to patients undergoing QCT depends upon the following factors: (1) scan parameters-kVp, mAs, slice thickness, number and spacing of slices, (2) patient size, (3) X-ray source/detector geometry; and (4) detector collimation and calibration. Hence the dose delivered is highly scanner specific. WebSeveral studies have shown that bone density may be measured by QCT using CT images that were ordered for other purposes. Using pre-existing images, including CT colonography exams, QCT allows for bone density screening without submitting the patient to any additional radiation exposure.
