Diagnostic efficacy of high-resolution ultrasound in the assessment of breast implants.
Pak J Radiol Jan ;30(1):12-7.

Abstract: Objectives: To assess retrospectively that ultrasound is an effective diagnostic tool in the imaging of both intact and ruptured breast implants. Magnetic resonance imaging (MRI) was used as the reference method. Study duration and settings: Retrospective study was conducted at the Department of Diagnostic Radiology, Dallah hospital, Riyadh, Saudi Arabia. Study duration was 1.6 year (January 2018- June 2019). Material and methods: A sample size of 60 breast implants (total 30 women with bilateral implants) was calculated using the WHO calculator. Ethical approval was taken from the hospital administration. All participants underwent breast US and subsequently MRI examination. Sensitivity,specificity,negative predictive value(NPV) and positive predictive value(PPV) for breast US having MRI as the reference method. Data was analyzed using SPSS version 24. Chi-square and ROC curve analysis was done. p value of <=0.05 was considered significant. Results: Total 60 breast implants were included in the study (30 women with bilateral breast implants). The Average age of women was 33.7 years +-5.9SD. Ultrasound findings reported that rupture was intracapsular in 04(6.7%) implants, 1(1.7%) implant had intracapsular & extracapsular rupture with silicone granuloma in the axilla, however, MRI findings revealed that rupture was intracapsular in 8(13.3%) and extracapsular in 1(1.7%) implants. Diagnostic parameters in both groups were sensitivity (94% vs 98%), specificity (55% vs91%), TPV (90% vs 98%), TNV (67% vs 91%) +LR (2.08vs10.8) -LR (0.109 vs0.02) in ultrasound and MRI respectively Conclusion: Ultrasound can be used as the first examination step in breast implant assessment.
