Obtaining good. fusion splices is much easier today, due to continued improvements to the fusion splice equipment, procedures and. practices, in addition to the evolutionary improvements in controlling optical fiber geometries. As a result, losses.
In CT, the total amount of radiation incident on the patient, known as the DLP, is the product of the CTDIvol and scan length (in centimeters) and is measured in milligray-centimeters.
Patients also spend just 20 minutes in the scanner with PET/CT as compared to 45 minutes with conventional exams. Although NaF PET/CT scans deliver a slightly higher dose of radiation than conventional scans (5 mSv versus 7.4 mSv), the radiation exposure is still low. In fact, NaF PET/CT may prove accurate enough to reduce the need for additional imaging tests, leading to lower overall radiation exposure for patients.
