| Abstract |
To determine the diagnostic reliability of magnetic resonance imaging (MRI) sequences in chronic groin pain (CGP) compared to surgery and try to propose a suitable MRI protocol. Forty-three consecutive patients with resistant clinical CGP underwent a pre-surgical pelvis MRI. Eight MRI sequences were acquired: axial fast spin-echo T1-weighted (FSE T1), coronal FSE T1, axial-oblique (in symphysis plane) proton density weighted with fat saturation (PDFS), coronal PDFS, sagittal PDFS, axial FSE T1 with fat saturation and gadolinium enhancement (FSGE), coronal FSE T1 FSGE and axial FSE T1 with Valsalva maneuver (VM). These sequences were reviewed for pubic symphysis assessment, adductor longus (AL) tendon and abdominal wall (AW) injuries. The same surgeon operated on all of these patients (26 AL and 49 AW). Sensitivity (Se), specificity (Sp), positive predictive value (PPV), negative prospective value (NPV) and accuracy of each sequence and combinations for AL or AW injuries were calculated in comparison to surgical findings. One hundred ninety-two sequences were obtained. Coronal T1 FSGE and axial T1 VM proved to be the most reliable sequences (accuracy: 91.67% in AL and 83.33% in AW). The best sequence combination was coronal T1, axial PDFS, sagittal PDFS and axial T1 VM (accuracy: 77.78%; Se: 100.00%, Sp: 69.23%, PPV: 55.56%, NPV: 100.00%). MRI has 77.78% accuracy, 100.00% sensitivity, 69.23% specificity, 55.56% PPV and 100.00% NPV in evaluating CGP, with coronal T1-axial PDFS-sagittal PDFS-axial T1 VM as the optimal protocol in terms of diagnostic performance within a reasonable scan time. Diagnostic performance of MRI was examined in the evaluation of CGP using surgery as reference standard. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. 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 26 April 2018.
All research outputs
#17,947,156
of 23,045,021 outputs
Outputs from Skeletal Radiology
#1,131
of 1,478 outputs
Outputs of similar age
#305,884
of 438,228 outputs
Outputs of similar age from Skeletal Radiology
#33
of 47 outputs
Altmetric has tracked 23,045,021 research outputs across all sources so far. This one is in the 19th percentile – i.e., 19% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,478 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.3. This one is in the 21st percentile – i.e., 21% of its peers scored the same or lower than it.
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 438,228 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 25th percentile – i.e., 25% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 47 others from the same source and published within six weeks on either side of this one. This one is in the 19th percentile – i.e., 19% of its contemporaries scored the same or lower than it.
