Mark your calendars!  We're going to Nashville.  May 29-31, 2020

The rapid evolution of multidetector CT (MDCT) has impacted all aspects of patient diagnosis from cardiac imaging to vascular imaging to hepatic imaging. The development of these new scanners requires a close look at all aspects of our CT programs ranging from our scan protocols, to contrast injection to the use of oral contrast. The new clinical applications require a better understanding of our scanners as the “room for error” has decreased with scanners routinely acquiring datasets in under 10 seconds. New applications have evolved from coronary CTA to virtual colonoscopy to dual energy imaging, to name a few. Classic applications like imaging the liver, kidneys or pancreas have changed with the role of multi-phase acquisition and post processing techniques becoming more critical. This has been both a time of change and a time of excitement. This meeting will provide the attendee with an improved understanding of the role of MDCT today and will help them improve their practice skills and knowledge base. Whether it is designing new scan protocols or learning new skill sets, this meeting will be a catalyst for increasing your core competencies through a series of lectures and hands-on training over a three-day period.

CME / ORLANDO, FL: 36th Annual Computed Body Tomography 2020

Save the date!  We're going back to Orlando.  February 14-16

Due to rapid advances in technology, radiologists and radiologic technologists often require a comprehensive review of recent advances in computed body tomography. This activity will focus on multidetector/multislice CT and newer systems including dual-source CT scanners. The schedule offers a series of 40-minute lectures designed to concentrate on specific topics in-depth, including state-of-the-art technology and software. Participants will have the opportunity to expand their knowledge of the latest concepts and principles of helical CT, thoracic CT, cardiac CT and CTA, the uses of CT in the GI tract, the liver, spleen and kidneys, as well as virtual colonoscopy and imaging the oncologic patient.

I teach adults in a college in Brazil. The most difficult for me its to make them to participate in an oral class. Do have a tip about how can I do to have an effective oral class for absolute beginners? What kind of material would you sugeest?

CT Scan Protocols / Arterial delay for hepatocellular carcinoma
« Last post by tbell on August 22, 2019, 02:58:22 pm »
Please advise on a siemens 64 slice dual source definition what arterial delay you should use for Hepatocellular carcinoma.

If we bolus track where would you set the roi and what should the HU units be set at?

Also, what delay after the tracker triggers should we use?

Preaching to the choir, but thank you very much for sharing your expertise and maintaining such a wonderful and useful site!!!

Given the UCSF paper, what kind of time delay to you use at JHU between ingestion and scanning? Our practice is similar to the UCSF quote, but it would sure be nice to get a longer delay in there to opacify distal SB loops.
