Factors Affecting Image Quality and Patient Doses


There are a wide variety of factors which affect how much radiation patients receive and the image quality produced by CT units. Each make and model is also unique in terms of how to adjust these factors. This presentation will first review what we mean by patient dose in CT specifically (i.e. CTDIvol, DLP) and then further discuss changes in acquisition parameters which can affect both image quality and patient dose.

Practice Changing Stroke Research Using CT-Angiography

Dr. Dariush Dowlatshahi MD, PhD, FRCPC

Stroke Therapy has changed dramtically since 2010, in large part due to CTA. This lecture will review the current applications of CT in acute stroke, and the future direction of the field. The speaker will:

  • Review the use of CTA and CTP for acure stroke therapy
  • Review discoveries made during the early adoption of CTA for stroke
  • Explore future uses of CTA for acute stroke

11:30 A.M. ET

Using a Patient Dose Management System to Improve CT Protocols

Anna Romanyukha PhD


  • How to use a dose management system to manage compliance and DRLs in CT
  • How to mange real-world clinical situations throguh automated notifications and alerts

Protocol Management In CT: How To Turn A Nightmare Into Better Workflow

Dr. Timothy P. Szczykutowicz PhD, DARB

CT protocol management is a daunting task for any site with more than one scanner that fulfills more than routine imaging orders. Most of us with multiple scanners in a hospital setting have needs from multiple departments for specific imaging protocols. These needs commonly motivate programming dozens-hundreds of protocols. Accommodating the ever-changing requests from (1) radiologists to align with their latest preferences and (2) new post processing software (e.g., AI CADe/CADx and ortho devices) also demands protocols be updated regularly. This talk will present this issue for CT technologists, and discuss tactics for gaining control of this task in an efficient manner.

Learning Objectives:

  • Understand what needs to go into a CT protocol
  • Understand the sources motivating changes to CT protocols
  • Learn methods for managing one's CT protocols across multiple scanners and locations

How AI Solutions Work and Why They Are So Brittle: A Technologists Perspective

Dr. Timothy P. Szczykutowicz PhD, DARB

AI is the new “hot topic” in radiology. Entire journals have sprung up to cater to articles on AI. Billions of dollars are being invested in AI solutions for radiology. With all this money and focus, the solutions in the clinic today are almost comical in how easy they are to break. For example, a change in series name, a change in the window width/level, or the presence of an “extra” series in the exam can cause some AI solutions to fail. This session will review data flow for some common AI solution models and review how parameters from CT protocols or CT technologist workflow can cause these solutions to fail.

Learning objective:

  • Learn the data flow for the most common AI based post processing, CADx/CADx methods.
  • Learn some common failure modes for AI solutions that relate to CT protocols
