Hi, what about SPECT/CT or PET/CT scans? How do I calculate the dose for the whole body, should I use the "k" for the trunk? DLP from Whole Body scans is measured from 32 cm phantom, so how do I calculate the dose for the head? Is it multiplied by 2 more or less?

Hello do I count the CTLI vol and dlp for the Scout (topogram) images as well to find the msv? Do you know if the scout images have less radiation than the rest of the ct scan?

[@HowRadiologyWorks]

Yes in general the scouts have much less dose than the diagnostic series. The total dose you get by adding up each dose

Sorry we don’t comment on individual medical questions, please call the facility that did your exam if you have questions

Hello, my son received a scan with a 32 cm phantom. Do I double the DLP to find the Effective dose using your calculator?

[@HowRadiologyWorks]

All body scans should be with 32 reference so you should not need to multiply DLP

@@HowRadiologyWorks Thank you so much

[@tinadavis2973]

@@HowRadiologyWorks Okay I wasn’t sure if I should multiply the ctli vol by two and that would affect the dlp. But the total dlp was given to us so do I just go by that number? Your videos are so clear and informative. Thank you

I got a ct scan done last week on lung, abdomen and pelvis. I recieved 13.5 mSv. Is this high or low in the spectrum of CT scans?? The scan itself lasted less than 5 minutes

[@HowRadiologyWorks]

See our video kzbin.info/www/bejne/eGjLZXWNbtCXn68 for dose ranges of standard exams, about 7 min in is abdomen and your scan is in the normal range especially if you had contrast.

Hi, hoping you can help. I got a CT calcium scan and I am concerned about the significant dose I received as I thought it should be around 1msv, but using your calculator it reports 6.521 mSv. The dose report provided states: Type: Scout Cardiac Helical Scan range (mm): 1136.250-1273.750 CTDIvol(mGy): 27.00 DLP (mGy-cm): 465.80 Phantom cm: Body 32 Thankyou

Hello when I went to the calculator to find the msv it said it was for one organ. Do all of the organs scanned have to be added to find the true effective dose? It said 0.015 for abdomen pelvis. Is this the correct number to use to multiply the DLP?
