CT Scan Technical Protocols
The purpose of this manual is to provide a reference for Radiology
Residents Fellows and Technologists when prescribing a CT examination.
Given the rapid evolution of CT technology in the past decade, the number
of applications for CT has expanded greatly and the techniques for
performing the optimal exam have also increased. The CT exam can now be
more effectively tailored to the presumed diagnosis. This reference is
meant to serve as a guideline for prescribing CT examinations, and should
be modified as needed for a particular patient.
In general, The process for performing a CT examination is as
follows:
- The exam is scheduled by the CT secretary (and concurrently the old
films are requested from the film library).
- The exam is protocolled by a resident or fellow on the CT service
and their name should be written on the protocol sheet. Particular
attention should be paid to prior examinations when prescribing an
exam. When there is a question about the indications for a study, the
referring doctor should be contacted by phone or pager.
- The technologist performs the exam and sign the protocol sheet. If
there are any questions about the protocol, the technologist should
contact the CT attending. If a radiologist checks the exam, the
technologist should indicate this (with the doctors name) on the
protocol sheet. The technologist should list the ICD9 code if
non-ionic contrast is administered.
- The study is interpreted by the radiologist. Reports are then
proofread and signed by the radiologist. All CT exams should be read
within 24 hours of the exam without exception.
Questions regarding changes in the protocols should be directed
to Scott Collins, RT(R)(CT)or Eric Waskiewicz, RT(R)(CT). We hope you find this helpful in providing optimal patient
care.
