MTMI--Multi-Slice CT Protocol Parameters and Dose

Multi-Slice CT Protocol Parameters and Dose

8 Hours ARRT Category A Credit

Dianna D. Cody, Ph.D.

About this Seminar

The recent radiation over exposures to patients from CT imaging procedures at several medical facilities have increased awareness of the importance of CT scanning protocols and the control of radiation dose. As a result many imaging facilities are reviewing their CT scanning procedures to insure that the appropriate tradeoffs are being made between the image quality needed to diagnose the patient and the dose delivered. This seminar will review the considerations that should be used for selecting appropriate scanning parameters to achieve the best results with minimum risk to the patient. Improving your knowledge of the parameters and capabilities of multi-slice/multi-detector CT scanners will help you become a better CT technologist and provide better results for your patients.

Educational Objectives

At the completion of this seminar, participants will be able to:

Comprehend the various CT protocol parameter settings available on their CT scanners.
Understand how adjusting those parameters affects both patient dose and image quality.
Understand how automatic exposure control (AEC) works in CT.
Understand under what conditions AEC works well and under what conditions it does not work well.
Recognize situations where a tube voltage different from 120 might be optimal.
Review CT perfusion protocols at their site for patient safety.
Recognize standard practice protocol parameters for routine CT exams (brain, chest, abdomen, pelvis),

About the Instructor
	Dianna Cody, Ph.D
Dianna Cody, Ph.D., is a Professor of Diagnostic Imaging Physics at The University of Texas M.D. Anderson Cancer Center. She is board certified in Diagnostic Radiologic Physics and has a Ph.D. degree in bioengineering. Dianna has conducted CT research through grants from the NIH and industry, is active in consulting for the imaging community, and has written recent book chapters on multi-slice CT. Dianna has been an MTMI instructor of technologist programs for several years. She combines her experience as an educator with her experience in CT scanning to present an informative, practical and enjoyable seminar.
Seminar Credit
This program provides 8 hours of Category A continuing education credit for radiologic technologists recognized by the ARRT and various licensure states. A certificate of attendance will be provided for each individual upon completion of the seminar. All attendees must attend the entire seminar to receive full credit.

Seminar Schedule

8:00 am	Registration and Coffee
8:30 am	Helical and MSCT Basics Review - axial platforms - basic image recon - no math - CT number - definition, contrast scale, effect of kVp, mA, time - conventional helical platforms - pitch - image width and beam width (married) MSCT - detectors - differences in image recon (interpolation overview - no math) - pitch - image width and beam width (divorced)
10:00 am	Informal Discussion and Break
10:10 am	MSCT Terminology by Vendor Thesaurus Parameters - what they are called and what does it mean?
11:15 am	Tube Current Modulation Approaches Importance of patient centering GE: Noise Index (Interface, Scout impact) Siemens: Reference mAs Philips Toshiba What is it really good for? (head/neck, PET/CT, peds) What is it not so good for? (head, CT perfusion)
12:00 noon	Lunch - (on your own)
1:00 pm	MSCT Dose Headline news, what's the real story? Technical factors that affect MSCT dose New technology designed to reduce dose How dose is determined - concept of effective dose vs. background radiation - dose value displayed at operator's console Patient dose report - NOT patient dose but dose to plastic phantom - manual technique - small variablitiy in reported dose - TCM technique - large variability in reported dose - How does patient size affect absorbed dose?
2:00 pm	kVp Options When is 120kV NOT the best option? - pediatric patients, smaller adults w/IV contrast(liver) When is 120kV the best option? - pre-contrast scans(liver) Is 140KV ever a good idea? - X-ray tube limited situations - head? CT Perfusion and Brain Exams Brain Perfusion - protocol parameters (by vendor) - what to watch for (images) - what can happen (patients) Brain Scans - routine standard practice protocol parameters - optional protocol parameters
3:00 pm	Informal Discussion and Break
3:10 pm	Chest - Abd - Pelvic Exams What is a routine exam? Target goal for each segment (motion, contrast) Standard practice protocol paramenters Options to consider..
