Take away:
Newer strategies to manage respiratory motion include accelerated imaging or free-breathing motion-robust image acquisition.
Artificial intelligence methods to manage motion artifacts are under development but require testing for generalizability

2- In small superficial soft tissue masses, ultrasonography is an excellent examination, allowing real-time manual compression, direct patient interaction and study with Doppler. Deeper lesions often require MRI for further characterization.

Being a successful expert reviewer =/= being so as an expert writer.
Why?
➡️ Difficult to be self-critical
➡️ No "formal" training in writing
How to improve then (besides accumulating years of exp😅)?

1⃣ : Formulate a specific, hypothesis-driven study purpose.
Don't be too general! Go straight to the point... and don't forget to close the loop by addressing the purpose in your conclusion.

In addition to current up to 4 weeks of vacation per year, the proposal would allow a resident to:
1) take up to 12 weeks of family or medical leave
2) additional family or medical leave with approval from program director on case by case basis.

2/ SWI can distinguish between which of the following?
3/ ANSWER: All of the above
SWI is a gradient-echo MR sequence that accentuates local magnetic field distortions from paramagnetic (i.e. hemosiderin) and diamagnetic (i.e. calcification) properties through signal loss in the form of T2*. Phase data can highlight these differences

DECT enables the synthesis of a wide array of images from a single acquisition because of the availability of CT projection data at more than one polychromatic energy level. Currently, six major approaches are used for DECT.

Do the benefits outweigh the risks in using MRI gadolinium-based contrast media (GBCM) in patients with kidney disease?

MAJOR new consensus statement from @RadiologyACR and @NKF published in @Radiology_RSNA at doi.org/10.1148/radiol…
A #RadInTraining #TWEETORIAL thread 👇
BACKGROUND:
GBCMs consist of gadolinium ions chelated with organic ligands to minimize toxicity from free gadolinium.
Which chemical class has a lower rate of free gadolinium dissociation?
GBCMs consist of gadolinium ions chelated with organic ligands to minimize toxicity from free gadolinium.
Which chemical class has a lower rate of free gadolinium dissociation?
Answer: Macrocyclic GBCMs are more stable (lower ratio of free gadolinium to complexed ligand). (Remember, 𝐋inear is 𝐋abile)
Macrocyclics form a complete ring, whereas linear agents form an incomplete ring.
Examples:

Drs. Shankar and Davenport from @UMichRadiology answer this Q in a fantastic meta-analysis of 16 studies done with group II GBCAs in stage 4 versus 5 CKD patients, published as @radiology_rsna article at pubs.rsna.org/doi/full/10.11….

2/11
The National Kidney Foundation specifically requested this stratified risk analysis (by CKD stage) of NSF after giving Group II GBCAs. The risk of NSF from Group I GBCAs, by the way, is already known to increase with decreased eGFR, especially in patients on dialysis.
