25 Jun 2016 NCLNs can be missed in chest CT at CTDIvol of <1 mGy (0.25, 0.4 and 0.8 mGy) regardless of IRTs. The most lung nodules (97%) were detected

Lung Low Dose with Tin Filter 2010-09-01 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).

For example, in a recent safety audit, we observed a factor of 8 difference in CTDI vol (5–40 mGy) between patients having the same examination, a single-phase abdomen and pelvis CT examination, for similar clinical indications. On the surface this would appear to be an inappropriate difference in “dose.” CONCLUSION: NCLNs can be missed in chest CT at CTDIvol of <1 mGy (0.25, 0.4 and 0.8 mGy) regardless of IRTs. The most lung nodules (97%) were detected at CTDIvol of 0.8 mGy. The most mediastinum structures were not sufficiently seen at 0.25-0.8 mGy. Advances in knowledge: NCLNs can be missed regardless of IRTs in chest CT at CTDIvol of <1 mGy. I have two tables: Exam (ExamID, Date, Modality) and CT(ctdivol, ExamID(FK)) with the attributes in brackets.

One of my tasks as a medical physicist is to determine the radiation levels that patients receive over the course of a single CT scan. It was also scanned at a CTDIvol 20% greater than the AD at 20 mGy and the ACR maximum threshold of 30 mGy. Results: At the NEXT 2006 25th percentile CTDIvol of 12 mGy, a 6.3 mm low contrast lesion was detectable in the 20 HUBB; 6.3 mm in the 10 HUBB and more » 10 mm in the 5 HUBB column.
