CT Scan Protocols / CT stone exams and routine CT chest (non-nodule)
« Last post by fflaherty on May 05, 2022, 05:45:23 pm »
What is the recommended axial recon interval for stone CT and routine chest CT (i.e. cancer f/u, etc.)? To this point we have been viewing axials at 5mm and coronals/sagittals at 2-3mm. We are now covering a hospital where most axial imaging was reconned at 2.5mm. Is there any consensus for slice thickness for these exams?

Thanks.

General Questions / Standard for Orientation of Scouts and Scans in CT Software
« Last post by KReed on February 02, 2022, 10:48:18 am »
Hi Dr. Fishman,

Hoping you can assist. I am trying to find a standard for the display of scouts and scans in CT software.

For example, if scanning a prone patient, should the scouts and scan be displayed as if the patient is prone ( right on right) or should they revert to anatomical position. ( left on right).

I have not been able to find any documentation on this. I am not looking for hanging protocols but orientation standards during acquisition and viewing.

Should the scouts and acquisition window show prone but the 2D, 3D, and MPR viewers show anatomical position?

Is there a place where I can find the standard orientation coordinates for the following:

HFS
HFP
FFS
FFP
HFDR
HFDL
FFDR
FFDL

Thank you. I look forward to hearing from you.

CT Scan Protocols / Sinus protocols
« Last post by Crodgers04 on August 25, 2020, 10:29:23 pm »
Does any hospitals still scan patients prone for sinus?

Hello Dr Fishman,

I hope you are well. We have an oncology patient attending regularly for CT. He is getting quite anxious as he has started vomitting quite quickly after IV contrast administration. Following consultation with his oncologist we tried 1mg Lorazepam and 1mg Granisetron orally i1 hour before his scan, he was still sick. On his next visit we plan to try a different contrast agent to see if that helps. Do you have any pearls of wisdom?

Best wishes

Liz

CT Scan Protocols / field of view influence on ct number
« Last post by Ian on April 20, 2020, 04:57:15 pm »
I wanted to do a small/medium field of view CT angio of the suprahilar mediastinum, neck and brain.
I was told by a GE applications person that I should use a LARGE field of view, which was big enough to include the shoulders.
She said this was because with a small field of view the density standardising peripheral detectors (64 slice) would not be scanning air if a small field of view was used.

This was illogical to me - I was after spatial resolution for 3D reconstructions, rather than measuring densities.

What is the correct method? - for CT angios and for CT neck?

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.
