In this video I tried 3 different methods for better unilateral hip imaging. Coil combination and patient positioning are one of the key for having good images. I will also share my thoughts on which methods I find as the best. Tune in and join me.

Our department always does a bilateral hips in the coronal plane (T1 & STIRS) so we use body coil with the spine coils. Then we do unilateral sequences with the same coils.

Great images👍 but I still don’t understand how come you got very good signal around the hip. Flex coil wrapped around the thigh a bit far from the hip and also turned the spine off? Anyway I will try to do so next time and let you know if it works or not 😊 thanks.

@winnieinsweden it’s how the coil is build. How far it will provide signal from coil towards anatomy. Every coil has its own characteristics

I normally use the flex coil and try to wrap it closer to that hip than the other. I don't completely wrap the hip. The patient is lying on the spine coil and when I snap in the flex coil I pull it over so the affected side has the coil wrapping down to meet the spine coil. Images always look great. We have to do exams in 15 minutes so there isn't time to experiment with other positions.

Nice thanks for comment.

Nice one Bac! yes, i dont think its too much waste of time to perform the 2 bilaterals in protocol (t1, stir) and then reposition for the unilateral sequences if theres benefit. Also, it can be helpful for arthroMR for when the patient comes back from getting the contrast injected. Thanks for sharing.

@Nguyen_MRI 10 ай бұрын

Thanks for comment. True point regarding arthro. Didn’t think about that since we don’t do it. ☺️

Lovely as always. For bilateral and unilateral hip I use the body coil over the pelvis in combination with spine coil. Using the same coil configuration I'd scan a unilateral hip if needed. But on my scanner using the flex coils take a little longer.

Good video as usual Bac. Dr rarely do just a side, usually the hip joint protocol is almost always scanned bilaterally, only if you're redoing it for the same pacient and you know the history , but otherwise nobody asks for unilateral protocols. Btw you can use in your video the positioning images from the Magnet's digital Manual , they're great so you don't need to take risky pictures inside the scanner room.

@Nguyen_MRI 10 ай бұрын

Thanks for the comment and for the advice. Yes unilatéral is rarely at our hospital as well. Only specific cases they want unilateral hip. Thereby I was curious if I could push the coil different from what we are used to. Regarding the photo it’s ok. Looks more original taking own photos compared to manuals 😂. Old phone and safety taken to account ☺️

@JD-fx1np 10 ай бұрын

Yes same here. But we do cor and ax bilateral, then 2 unilateral sequences, pd fs. Why not put the large coil on top, then wrap the smaller flex around affected hip and when scanning those 2 unilateral sequences, use the small flex and turn off spine elements?

Thanks Bac! We use the ufl 18 with spine coil. Might try the wrap next time though 👍

Awesome. Let me know what you think if you try so 👍

@efawscuba610 10 ай бұрын

Interesting concept for better signal. Unfortunately my hospital's protocols have a bilateral view before the unilateral sequences.

@Nguyen_MRI 10 ай бұрын

Same here mostly exams bi lateral. But sometimes unilateral if imaging a special case. Thereby it’s good to know how to use the equipment ☺️

@user-nz4ej2sl5y 10 ай бұрын

Unilateral hip ultraflex 18 for normal size patients . Obese or larger patients 18 channel body coil. Morbidly obese patients body 18 on top ( not wrapped ) in combination with spine coils

@danfascia 10 ай бұрын

I would always begin a single hip protocol with at least a STIR of the whole pelvis since non articular pathology is so common in hip presentations. However then, I would move on to the narrow FOV single hip images you show nicely. Could you acquire the whole pelvis using just the spine coil, then activate the flex to do the narrow FOV? to save repositioning

@Nguyen_MRI 10 ай бұрын

Good question. Would be difficult without enough coil coverage for both hip with only spine coil unfortunately. It’s pro and cons using either approach.

Hi Bac. Do you rotate the patient's leg medially as in XRay positioning, for MRI hip joint and MRI femur? Thanks in advance.

@Nguyen_MRI 9 күн бұрын

Good question. No not routinely. But this is something I've been thinking about testing out more.

@kalfriesen5670 10 ай бұрын

I'm curious how different body habitus' might make the different options to do unilateral hips look. It would be fun to test out sometime.

@Nguyen_MRI 10 ай бұрын

Yeah the penetration of ultra flex is not as great as body 18. So thicker patients I strongly believe ultra flex will suffer compared to body 18

Radiographer is the correct term, depending on your country and the education you've completed. In Australia we are called Radiographers, as we have completed a degree for Diagnostic Radiography.

@@calbang same here in Norway. Radiographers after the degree. But I only work with mri after my education so thereby my speciality is in the field of mri.
