Evaluating the effectiveness of abbreviated breast MRI (abMRI) interpretation-training for mammogram-readers: a multicentre study assessing diagnostic performance, using an enriched dataset

“…The diagnostic accuracy of abMRI is similar to that of fpMRI when reported by professionals expert in fpMRI interpretation (11)(12)(13)(14)(15)(16)(17)(18)(19), while shorter acquisition (3-13 minutes abMRI vs. 15-32 fpMRI) and reading times for abMRI (0.6-3 minutes vs. 3-7) promise potential cost savings in comparison with fpMRI (11-14, 16, 18, 20, 21). However, important unknowns include the feasibility of upscaling abMRI capacity (20,22).…”

Abbreviated magnetic resonance imaging in breast cancer: A systematic review of literature

“…Three researchers carried out this review, and in case of disagreement, some articles were included for full-text review. Therefore, documents were excluded, of them because not reporting abbreviated protocols, for being reviews or technical notes, either of general aspects of the use of magnetic resonance in the diagnosis of breast cancer or specifically on abbreviated protocols for breast cancer [20] , [21] , [22] , [23] , [24] , [25] , [26] , [27] , [28] , [29] , [30] , [32] , [31] , seven documents that corresponded to editorials, letters or erratum, two documents because the full text was not available in the English language, three more there was no full-text availability, and two documents that studied animal specimens. After the previous process, articles were maintained for full-text review, which reported breast ABB-MRI protocols.…”

“…Additionally, the search was carried out in August 2019, which implies the exclusion of recent works. Similarly, Geach et al [32] presented a systematic review and meta-analysis of ABB-MRI for breast cancer screening that included the FAST sequence; the search was performed in November 2019.…”

MRI Screening of BRCA Mutation Carriers: Comparison of Standard Protocol and Abbreviated Protocols With and Without T2-Weighted Images

“…An unexpected finding was the significantly higher pooled specificity for Abbreviated+T2 than for Standard. In comparison, two recent meta-analyses showed no difference in sensitivity or specificity between abbreviated and standard protocols [24,25] . The meta-analysis by Baxter et al (n=2588 patients from five screening studies) [24] reported abbreviated MRI to have pooled sensitivity of 90%, pooled specificity of 92%, and pooled AUC of 0.94, which were not significantly different from values of 92%, 95%, and 0.97 for standard MRI.…”

“…The meta-analysis by Baxter et al (n=2588 patients from five screening studies) [24] reported abbreviated MRI to have pooled sensitivity of 90%, pooled specificity of 92%, and pooled AUC of 0.94, which were not significantly different from values of 92%, 95%, and 0.97 for standard MRI. The meta-analysis by Geach et al (n=2763 women from five studies, with only one study including T2W sequences in the abbreviated protocol) [25] reporting abbreviated MRI to have an overall sensitivity of 94.8% and overall specificity of 94.6%, using standard MRI as the reference standard; sensitivity and specificity did not differ between the two protocols among three studies with follow-up data. Specificity for both standard and abbreviated protocols in our study are somewhat lower than previously reported for various screening breast MRI protocols.…”
