Results: At CTDIvol levels of 25, 20, 15, 10 mGy, radiation dose levels had no effect on the accuracy of iodine quantitation; at CTDIvol level of 5 mGy, the accuracy of iodine quantification was the poorest, with the mean APBiodine of 4.33% (P<0.05).

•  In only a very few situations is a cumulative CTDIvol > 2000 mGy observed. •  Examples of important medical procedures where these high CTDIvol values are observed include: –  Cryoablation and RF ablation procedures –  Cementoplasty or multi-level blood patches for CSF leaks

IFF Accumulated DLP Forward Estimate (Row 6) exceeds DLP Alert Value (Row 4) or Accumulated CTDIvol Forward Estimate (Row 7) exceeds CTDIvol Alert Value (Row 5) 9 In order to provide precise diagnoses, oncology examination is all about recognizing lesions, and visualizing and quantifying tissue. With Dual Source Dual Energy scanning – the only modality that enables DE scanning at doses comparable to a conventional 120 kV scan –, you will be able to get all the information you need in a single scan. The mean, median, and 75th percentile of CTDIvol (mGy), and DLP (mGy.cm) for all these included studies are reported in (Table 1).

Se hela listan på oatext.com The technical parameters obtained were kVp, mA, scan range (cm), computed tomography dose index (CTDIvol), display field of view (DFOV) and dose length product (DLP). Effective dose (ED), defined as the product of DLP by an ED normalized weighting factor k (mSv.mGy-1.cm −1) ( 8 ) was also obtained.
