  • Any good reference articles on the basics of CTA head and Neck?

    Have to start covering a hospital ER where they do these and I don’t have much experience. Usually will have Neurorad backup, but just in case!

        Neurorad here. Read up on craniocervical dissection in Radiographics .

            These have been helpful but I am looking for a “radiographics” style article with examples of common pathologies etc…

              sounds like a good RD article to write.

              I mean there’s a lot of pathology ranging from vascular to nonvascular portions so you might have to find a lot of those articles. 

              You have anatomical variants, NASCET critieria. neck pathology, acute vascular complications among others for each report. 
              Are you also going to be reading RAPID’s/cerebral perfusion maps?

                Casestacks website is good.

                  Don’t have an article but a few tips based on common misses:
                  -Biggest “ouch” misses are always the non-vascular things — skull base masses, spine masses/osteo, and lung stuff
                  -PCA pathology is probably most commonly missed since every CTA has some degree of opacification of the basal vein of Rosenthal which runs alongside it. The MIPs sometimes don’t help. I always recommend checking the PCA on coronal and/or sagittal. This will really build your confidence if you’re ever calling tight stenosis/occlusion here
                  -ICAs at the skull base and cavernous segments. People blow by stenoses and aneurysms here every now and then
                  Other than those three things, if you can read a CTA anywhere else I think you’ll do just fine. Your Neuro colleagues can help you troubleshoot unusual things and overcalling/undercalling a stenosis here and there isn’t a big deal.
                  Oh — bonus tip to check MCAs on sagittal. I find this is really the best way to catch M2 occlusions.

                    Agree with articles listed above. 
                    As a neurorad, i’ll say CTA misses I usually run across are typically anatomic things, less likely a decent rad will miss an occlusion, dissection, etc….Just make sure to always double check the neck structures, thyroid, skull base, etc – I  see a lot of misses in those spots.

                      Good rec by apoplexy on the M2 verification on the sagittal. I’m curious as to how much something like “stenosis” is actually acted on. Of course, the aneurysms and occlusions I see the “value” in, but the other stuff just seems academic, and to be quite honest, something the system built in to portray meaning but ultimately there isn’t much one can do about it… but hey, mission accomplished, they order CTAs on everyone, yay!

                      Usually people who have intracranial atherosclerosis tend to not have much cervical one. So yeah unlike CEA which works very well, there’s not much you can do for intracranial stenoses. I still report them if they’re noticeable bc it feels weird not to, but I don’t think there’s too much you can do there.

                      As above, always confirm the vessels patency on sagittal and coronal reformats. I saw a case this weekend where an outside rad missed a proximal M2 occlusion. Thankfully, the telestroke neurologist caught it after their exam and the CTA read didn’t match up. There was a vein right next to the M2 that I am sure the outside rad thought was the patent vessel.
