CT Protocols

IMPORTANCE OF PROTOCOLING

Our goal is to protocol CT and MRI one week in advance 
(ie. up to 1 week following the end of your rotation)

Sometimes, CTs or MRIs need to be upgraded (for example: to upgrade from a noncontrast to an IV contrast enhanced CT or if a CT urogram is just ordered with IV contrast and not with/without IV)

There are teams of people to help us do this. 
Here are the email groups depending on the site:

Mount Sinai BISLR Body CT Protocols
CTISUS 
Radiation Risk Calculator
Radiation safety information for patients
  • Annual background radiation ~3.1 mSv/year
  • CXR (PA&Lat) ~0.1 mSv
  • 7 hour airline flight ~0.02 mSv
Gurney Weight Limit ~ 350 pounds

If the patient has a severe anaphylactic reaction but needs CO+, can use BariCat or RediCat instead of Omnipaque



ABDOMEN / PELVIS

ALL BODY/CHEST PROTOCOLS SHOULD USE DR. FRIEDMAN'S SITE


NEURO HEAD & NECK

  • SL: Protocol all cases in IDX
  • West: Protocol all CT cases in IDX, review all MR protocols with Dr. Lefton (or covering attending)

CT Head (~2 mSv)
C- for trauma, headache, AMS, stroke, seizure
C-/C+ for mass, infection/meningitis, but MRI with gad is better we do C- for detection of hemorrhage. Its difficult to r/o hemorrhage on a C+ only study.

CT Neck 
almost always C+
if evaluating thyroid, C-
if worried about foreign body, can be C- or C+

CT Sinus/Facial bone
check Rx to make sure they don't want stryker protocol protocol

CTA Head
C+ with MIPs by tech and better MIPs by you in Vitrea
for West inpatient 16 slice scanner, you must make MIPs yourself in Vitrea

CTA Neck
C+ with MIP images by tech
for carotid dissection, MRI with axial T1 fat sat is best to look for hyperintense crescent

CT Brain perfusion
C+ “perfusion protocol”
only on 64 slice scanner
must be 80kV

CT Spine
C- is routine
C+ for  r/o infection, post op
C- / C+ is sometimes ordered, should typically convert this to C+ only

Any head CT ordered by Dr. Kopell

CT neck w/wo for hyperparathyroidism

"CT Neck Routine" 

Comments: 4D hyperparathyroid
