The thyroid is not required for cervical spine and can be collimated off with today's technology. th-cam.com/video/ZcvH11MfgUo/w-d-xo.htmlsi=isuWBoKu65LWfkdu
the sponge should be under the humerus to include the elbow for proper ab duction also you need to know how to do this when the proximal humerus is fx ed
I made a video of how to do cervical spine without using any centring points, only using accurate collimation. Lowest dose cervical spine th-cam.com/video/ZcvH11MfgUo/w-d-xo.htmlsi=NpJ1f9S6c4Fenuv5
Fortunately this high dose projection is rarely done in these days of CT and MRI. In the good old days, we would collimate to an 18x24cm cassette 8x10 inches with a small up tilt. A better approach for most patients is to do the procedure prone oblique as the spinous processes can be palpated. Never use centring points derived by the number of finger widths. Judgement of the radiograph will not be according to what is in the centre. It will be by how well it is collimated. So on that measure, the dose from my approach would reduce radiation dose to 1/4. I would also use lead rubber in the corner of the image to exclude primary beam to one of the ovaries. Understand the anatomy well enough to use it directly to cause perfect collimation. That way you master radiography rather than remembering the centring point according to how many finger widths required.
If your positioning requires using a centering point, don't center on the teeth. Center 3cm below the teeth, or angle the tube. There is nothing much of any radiological value above the teeth. Tube angulation alone will not alter the geometry of the projection
It is a projection that is performed poorly. That is because no one seems to bother with postural positioning. Have the patient raise their shoulder and lower the hip they are lying on. That will standardize all your patients. Saying the angle is 3 degrees is a complete guess. It is also a projection directly related to the lateral lumbar spine. Take that first and see how the L5S1 appears and angle the tube. I hope you realize that tube angulation is only collimation. That means centering points are pointless and useless. Why remember 'rules of thumb' when you can actually learn the anatomy? I always use a piece of lead to block 1/3rd of the dose and prevent ovaries from the direct beam.
Hi! Could I please ask, so if the patient’s left shoulder is touching the bucky, then the L marker should be flipped and placed on the left side of patient? Thanks.
@@kimpham4778 Yes. The marker should always be placed on the correct side of the anatomy. When performing a PA projection, the marker should be flipped as well.
Just for anyone watching this in A+E xray, you would never put a sponge on a patient in blocks laying down on a trolley. You shouldnt move them at all. You have to do this xray without the sponge or moving the neck a lot of the time.

very good LPO

why angle CR 15% (caudad) in anterior and why CR 15% (cephalad) in posterior
Why the lead shield there?
Thank you... In the lateral, the femur didn't fall completely... 🤔?
if the jaw is suprimposed over the spine, do you move the head toward or away from the IR?
Which position are you referring to?
Thank you 🙏🏾
thanks for mention SID !!
Thank you! Very well explained 🙂
There is a 5 degree caudal angle as well
only for broad shoulders
I'm brazilian, Jocelyn. Very good.
Thanks
what is the sid ?
40" SID
Are u a radiographer
Cephalic angle* if it wasn't obvious to anyone else at first listen
What is the SID?
72"
Very helpful for comps today thank you!
Really good explanation

Doing AP oblique gives you the information of Right side of C Spine.
That's what I thought?
For a well collimated alternative, watch this video. th-cam.com/video/ZcvH11MfgUo/w-d-xo.html

It's very useful for my job Thank u 👍
Good position where are you I needed job
Clavicle and scapula
L comment.
Thanks
hi I though having your marker on the pt is illegal
Lat Clavicle,,,only
👍 Great
This is for facet ioint xray, right?
Marker flipped and right marker on right side of anatomy.

Which imaging process is this done by. Catscan??
Marker should be a flipped right since you are performing a PA
wait... isn't the vertebral column doing to superimpose on the SC joint? that doesn't look right :(
Which side is that though?
Omg Thank you so much for this, it really helped me
thank you~

Akka please help me .. today is my exam.. 😭😭😭
🤣
Hope it was okay?
😂😂😂
😂😂😂
“Pretty good” isn’t even a central ray. Why is this even up???
Lilboi Jake lol T2/T3
Who will tell the SID Exposure just position thats it incomplete video
100cm
Pls upload more routine like cxr spines
Love your videos👍🏽
