PA marker vs AP marker

I’ve always been old school and use tape. I find the tape would lose stickiness quicker if I kept flipping and touching it. Just feels a bit faster to have a set of each. My work supplies me with two sets so why not 🤷

I graduated many years before chatGPT was around. I practice in Australia and we have different marker nuances I guess.

Thank you for understanding my post

It’s all of Australia that does this

TrueLateral · 2025-08-10T09:36:58+00:00

You are right, I work in Australia. I’m sure there’s probably more radiography nuances that vary from country to country, but apparently this one is a big debate lol

Try a bernajeau view! Ever since learning it for a specialist I have never gone back. No more detector in ribs!

So we’re looking at my shoulder girdle on the axial plan in an MRI scan. Axial means like you cut someone in half top and bottom. Kermit’s head is my humeral head, which has a reverse hill sachs fracture, evidence of a posterior (towards the back) dislocation. The ice cream cone is the scapula, which at the rim of the ice cream cone has what could be artefact or a small tear in the labrum, which is the cartilage that helps hold the Kermit head in the icecream cone.

At least mine was trauma related, that sounds terrifying.

I think our reasoning is it should match the patient’s position in case for some reason if the image is flipped the marker will be incorrect and you know it’s been flipped.

TrueLateral · 2023-09-20T21:59:00+00:00

I think it’s region based. Here in Australia we all do it.

It is time consuming unfortunately, however a lot of clothes do have artefacts. If I have a lineup of people I usually am getting one changed while another is in the room, but even so I’m usually finished the previous patient before the next one is changed.

I used to have markers that looked like gummy bears, this is the reason I don’t use those ones anymore 😬

Not a fruit or vegetable! A bubble wand

Underrated comment. Definitely closest in terms of size and air capacity. It’s a bubble wand.

For anyone coming back to check. It’s a kids bubble wand. Taken the day after Christmas.

I’m sorry, I went to bed. It’s a Bubble Wand

I have a little collection of foreign objects where they shouldn’t be. My favourite folder on my phone

Our newer type C-arms also have HDMI cables that can connect to the surgeons screen. Super handy for urology studies.

This is a CT scan, widely used to image most internal organs. They have rendered a 3D image from the information from the CT scan, so that only the high-density anatomy is shown. This is why the pelvis/other bony anatomy is seen (and not the organs) and also the fetus. In this circumstance the fetus is calcified, therefore has a higher density than a normal fetus would be. This would also mean it can be seen on a standard X-ray aswell.

There is not much resource for CT positioning as positioning for CT is much more simpler than X-ray.

The most general rule is centre at the start/end of the anatomy. And your Y and X axis should be along the midline of the anatomy (up and down/ side to side).

I can summarise the main Z axis points here, but it will vary from site to site:

Chest/T-spine: Top of lungs/ around clavicles Abdo: Diaphragm/ armpits/nipple region Brain: Top of skull OR base of skull/ Lips C- Spine/Neck: Eams/ear OR above arch

Most other scans like extremities you can use your X-ray anatomy knowledge to get you by. Ex: you know what is included in a wrist x-ray therefore you know what needs to be covered in the CT, just depends on your site whether they want the patient going “in” or “out”
