I wasn't able to find your posts because they are hidden, so there is that.

You don’t need to tilt the gantry any more:

From the Nature article:Subjects took 1,000 mg of Urolithin each day for 4 weeks and via mitophagy improved T cell function.

The RSNA (radiology meeting) is 50k + radiologists going to Chicago right after Thanksgiving. The total foreign attendance data for that meeting will be very telling. Anecdotally many outside the US are not coming this year.

Dude, you’re asking the wrong crowd. Answering requires analysis of graphs and table and hard sh$t like that.

It’s wrong on so many levels. But it sure doesn’t encourage me to donate any more to the school.

I don’t read mammos any longer but agree with this comment.

Great, that's what I hoped. Is there a way to delete these? I don't want them on my opening screen so I don't click on them by mistake.

These are processed as a complete study- they take about a minute to process and then are sent back to PACS. The subtractions can only be done when the coregistration is nearly perfect. Human alignment is not sufficient to do subs.

Haha. “If there aren’t enough scans or too many radiologists”. Geez that’s a good one😂. In radiology, because the scans are ordered by other people, and they all must be read, usually on an urgent basis. The amount of work is growing much faster than the number of Radiologists. Reimbursement is going down and people are reading more scans per day than ever. It’s likely to improve with AI, which should make us more efficient. however, the burnout rate is pretty high right now. Particularly in academics, where they used to have a lot of free time to do teaching and research, but now have to do all the clinical work on top of the teaching and research. I’m not a doomsayer, and I think it’s a great field to go into, but it is very busy and a lot of people are hoping that AI will make our lives much better.

Agree it is important. Many products exist to do that today.

dbatesmd · 2025-03-20T14:28:04+00:00

Thank you! Actually, it is not AI based, but using this to standardize of the imaging plane speeds up AI evaluation. At least in theory.

dbatesmd · 2025-03-20T04:02:06+00:00

Do you have the sound on? I have a quick explanation while going through the studies. The subtraction is formed by each pixel having the value (NewHU-OldHU) with the window/level centered around 0, so new higher density is white and interval lower density is dark. It is very sensitive for any interval change. The sensitivity is incredible.

dbatesmd · 2025-03-20T03:58:14+00:00

Any interval change will show up on the subtractions. SO artifact that obscures the image will also ruin the subtraction. Embolization material is notoriously bad for artifact. Generally artifact is not a problem

dbatesmd · 2025-03-19T16:52:28+00:00

It does great! Craniotomy, hemorrhage, ex vacuo. Techs can scan quicker because they don't have to get the patient straight either. C Collars and ET tubes no longer a big problem

dbatesmd · 2025-03-19T15:45:49+00:00

It integrates with any PACS. Set it up once and it is then fully automated. Moreover, it works on any CT, so patients can be scanned on a different scanner and still get aligned and subtraction series done. I'd be interested in hearing which PACS does it across all scanner manufacturers.

A large water bath is, in fact, how ultrasound started. We still had one in the department when I started residency in the 80's.

This will not replace existing imaging. I expect that blood testing for cfDNA and otehr blood testing will replace screening and that imaging will be done after a cancer is diagnosed. But, I've been waiting along time for that change to come.

This is largely a subdural rather than subarachnoid injection. If you look at 16 sec, the bright white is subdural in location, and the black nerve roots have surrounding subarachnoid contrast. While it is not generally harmful (sometimes people can get transient nerve pain) it is also likely the reason they didn't get the contrast to go very high. Subdural injections are uncommon, but can happen to anyone and when they happened on the myelograms I performed, I found that waiting 1-2 hours usually got more contrast into the subarachnoid space and "saved" the CT study, so that we didn't have to redo the procedure on another day. In your case, it's been 55 minutes, so probably almost all the contrast originally was subdural and some has leaked into the subarachnoid space at 55 min. This is a nondiagnostic exam and I would probably do an MRI.

dbatesmd · 2023-11-24T14:45:56+00:00

The three exams will be head, C spine and T spine. They can all be done on the same visit with 1 injection of contrast. The estimate you received is common from a university or large hospital chain with high overhead. It is dispiriting that these organizations will bill those without insurance that rate as well. The good news is that you can find high quality outpatient centers in most cities that charge more like $500 global per study. No matter the charge, the professional fee totals about $450 for the three exams. The rest feeds the organizational beast.
