A single-sided NMR instrument was used to investigate the ability of the T1 relaxation constant to distinguish between regions of low and high mammographic density in human breast tissue.
Measurements were performed on 5 breast slices obtained from 3 women undergoing breast reduction surgery or prophylactic mastectomy.
T1 values measured in regions of high mammographic density in both the full breast slices (T1 = 170 ± 30 ms) and excised regions (T1 = 160 ± 30 ms) were found to be significantly different (P < .001) from those measured in regions of low mammographic density, in which T1 = 120 ± 10 ms was observed both in full slices and excised regions. There was no statistically significant difference between the T1 values measured in the full breast slices and those measured in the excised regions.
The findings suggest that portable NMR may provide a low-cost means of assessing mammographic density in vivo.
This research output has an Altmetric Attention Score of 7. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 30 May 2023.
All research outputs
#6,646,467
of 34,089,221 outputs
Outputs from Magnetic Resonance in Medicine
#1,819
of 8,380 outputs
Outputs of similar age
#105,427
of 490,721 outputs
Outputs of similar age from Magnetic Resonance in Medicine
#23
of 105 outputs
Altmetric has tracked 34,089,221 research outputs across all sources so far. Compared to these this one has done well and is in the 79th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 8,380 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.3. This one has done well, scoring higher than 77% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 490,721 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 77% of its contemporaries.
We're also able to compare this research output to 105 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 76% of its contemporaries.
