Expanding MRI Safety to a whole class during radiographer training is such an important point. So many programs only teach MR safety as 1 lecture or 1 week of training. Some years ago I inherited a position teaching clinical MRI procedures and found that the students MR safety training was 1 week of their radiation safety training class. These future MR technologists had never researched an implant, looked at MR conditional labeling, or practiced a safety screening!

Thank you so much for watching Scott. Your input is absolutely valuable. Completely agree with you on the fact that it's crucial to start enhancing MRI safety from an academic perspective as well, before students fully dive into the practical aspects of the job. Without a solid understanding of essential safety concepts, it's really hard to imagine a cohort of healthcare professionals ready to tackle the numerous MR safety challenges that may arise throughout their careers!

You'll be amazed at just how ferrous the little bra hooks/rings at the back are. Even for non underwire bras, the amount of artefact these hooks/rings give, especially for chest/cardiac/neck imaging..is just phenomenal. It is best to get the service users to take any bra that has any sort of clip/ring off. Just leave on only non-clipped sports bras.

Luckily there are services like those offered by Gio which, along with reiterating the importance of this, they also provide a list of manufacturers which supply sports bra to facilitate this "transition" .

hi decreasing the phase fourier like 7/6 will reduce the scan time and snr, how we should use
@everything-mri2 ай бұрын
Hello! Setting the phase partial Fourier parameter really depends on what you need from the examination. For instance, if you're after high SNR images and your patient can stay still, you might want to skip using partial Fourier. However, if you’re dealing with a patient who finds it tough to keep still or you're imaging areas like the heart that are constantly moving, adjusting the partial Fourier could really help. My advice would be to go for a higher partial Fourier ratio, like 5/8 or 6/8, when you need to speed things up. This can cut down the scan time quite a bit, though it does mean a bit of a compromise on image quality and a higher chance of artifacts popping up. The 7/8 setting is a more balanced choice; it speeds up the scan a little without sacrificing too much quality, making it a great choice for those times when you need a faster scan but still care about clarity. Hope this helps!

Few things can feel so humbling as a tough CMR! I think a few things to try: 1. Coaching the patient again; be sure they understand the instructions. Otherwise try to decipher the cause: is the breath hold too long? is expiratory breath hold too difficult? CMR is a long study for most sites, it may also be helpful to speak with your reading cardiologist about what is the primary clinical question for the study, and re-prioritizing the sequences. If the main question is LGE, no sense in re-running Cine's over and over again when a limited number of breath holds might be better used for mapping, LGE, Flows, etc. 2. If breath holding is not going well, also consider having the patient do shallow breathing or just free breath it entirely. - Real time cine imaging is helpful in this scenario. It will sacrifice image quality and be much more work for the Drs to do analysis, but may also be the only way to achieve clear imaging. - LGE is frequently done with the MOCO technique as a freebreathing scan, with good image quality. It is important to know it's drawbacks though, MOCO only works in-plane, like propeller, so running a MOCO in 4 chamber orientation may look more reliable than it actually is. It is best kept as Short axis or 2 chamber. MOCO also uses non-rigid correction ie it warps the image to look right, so best to run it in systole so that the heart is definitely the same shape/size in each of the averages it uses so that it doesn't warp LGE to look more or less bad than it actually is. On a 3T, non MOCO single shot SSFP LGE image quality can be quite good free breathing. 3. Try a HASTE/SSFSE for dark blood over multiple heartbeats. If you're on a Siemens and really need a fast-ish T1 Darkblood, you can take the radial ssfp cine from the Siemens tree and beat it up into a gated GRE darkblood static image. Looking forward to future discussions on CMR!

Hello. Can you please elaborate on why ProHance is "the worst" contrast agent for cardiac MRIs? I'm just curious as in my (also big) clinic there is only Primovist (liver) and ProHance (everything else), so our cardiac MRIs are also done with ProHance.
@everything-mri3 ай бұрын
Hello. Thank you for watching. We have forwarded your question to Stephen. Here below is his replay: I shall stick to the everyday macrocylic contrast agents. The first clue is in the medication charts that come with the contrast media- Prohance is indicated for "use in MRI in adults to visualize lesions in the head and neck" (Bracco). Gadovist is indicated for use in MRI in adults and children of all ages to visualise lesions and MRA in all parts of the body, as is Dotarem- this is all from the manufacturers charts and FDA. From research, of the 3, Gadovist has the highest T1 relaxivity (5.2 L/mmol-s) followed by Prohance (4.1) and then Dotarem (3.6), which means that Gadovist produces the highest signal intensity (SI) for comparable dosages. As Gadovist is twice the strength of both Prohance and Dotarem, half the dose of Gadovist can be used as compared to the other 2, although 0.15 mmol/kg is recommended rather than 0.1. Additionally Gadovist has a much higher viscosity and osmolality (5cP and 1603 mOsm/kg) than both Prohance (1.3 and 630) and Dotarem (2.4 and 1350). Gadovist has higher SI at first pass perfusion and sticks around longer for tissue characterisation (LGE) than both Prohance and Dotarem (for cardiac MRI). Also from experience, for the equivalent dose of Dotarem and Prohance, Dotarem performs better both for first pass and LGE. With regards to Prohance (sticking to the question), a single dose will have left the myocardium within 3 minutes of administration; even a double dose barely allows LGE assessment at 4 minutes. If you must use Prohance, I would recommend a triple (also approved by the manufacturer & FDA) or quadruple dose for full cardiac MRI assessment; bare in mind though that you'd need to work out the appropriate split for perfusion if doing stress and rest perfusion before topping up for LGE.
@stoyanvalentinov18613 ай бұрын
@@everything-mri Thank you very much for the detailed answer! We are applying twice 0,2 mmol/kg for a total of 0,4, so we are already at the quadruple dose. Our LGEs start 8 minutes after contrast injection, which seems bit late in this context now.

Hi Julien, with regards to TR values you mentioned we have a larger threshold using a 3T scanner. Aside from having a stronger magnetic field, anymore reason regarding larger threshold with a 3T magnet
@everything-mri4 ай бұрын
Hello. Thank you so much for watching. Regarding your question, the main reason for the extended TR threshold in a 3T scanner compared to a 1.5T is the increased T1 relaxation time at higher magnetic field strengths. T1 relaxation time is the time it takes for the longitudinal magnetization to recover to 63% of its original value after being perturbed by radiofrequency pulses. At higher field strengths, like 3T for example, tissues have longer T1 relaxation times, which necessitates longer TRs to allow for sufficient recovery of longitudinal magnetization and better contrast in the resulting images. I hope this make sense!

@everything-mri4 ай бұрын
That's a tricky question. Meaning that as usual in MRI, there is always a balance to consider. There is no "yes" or "no" answer since there are a lot of factors involved. You need to consider things like at what magnetic field strength your scanning and the potential acquisition time involved. In fact, increasing the NEX can beneficial to get some extra signal, especially if you work at low field strengths, but the patient may move as a result of a greater scan time. Find the right trade off is the key

You forgot about the 3d LGE Scans from Philips being done within 15 Secounds for a whole ventricular volume. This ist a big advantage over Siemens. Siemens isn`t even close there. There is also a big problem with whole heart sequences from Siemens: they take over 10 min. while Philips can do this in around 3! Philips is just bether in cardiac and neurological examinations
@everything-mri5 ай бұрын
Thank you. I really appreaciate your comment. Obviously, the more feedback like this one we have the more fair and comprehensive will be the comparison. However, this will always remain quite subjective. For example, while I agree that sometimes 3D whole heart acquisition can become pretty long in Siemens, I disagree with the statement that it generally takes over 10 mins. It should really be assessed on individual cases. I have acquired plenty of 3D whole heart with Siemens scanners in less than 4 minutes. Again, I think this varies a lot according to personal experience and knowledge of the scanner. I am very happy to hear you have had a positive experience with Philips scanners though 👍🏻 my personal feeling is that they are very reliable and image quality obtained can be very impressive!

Thank for claryfing this further. So, if you acquire sequences that involve spectral saturation in breast MRI, when the frequency selection window shows up, you can choose with the right click to zoom in and look with the mouse for the 0! That’s the ideal saturation point. Then click apply and run. That’s usually the peak on the right. If you want to suppress the silicone instead, you need to usually choose the peak on the left!
