Financial implications of biparametric prostate MRI

Academic Article


  • Background: Multiparametric magnetic resonance imaging (MP-MRI) targeted biopsy has been shown to identify more clinically-significant cancers and reduce the detection of clinically-insignificant disease when compared to systematic biopsy; however, the wide-spread accessibility of MP-MRI is limited. A potential strategy for reducing the cost, study time, and contrast-associated risks associated with MP-MRI is elimination of the dynamic contrast-enhanced (DCE) sequence, relying instead on biparametric MRI (BP-MRI). BP-MRI has been shown to have a diagnostic accuracy and cancer detection rate that are equivalent to those of MP-MRI. Methods: We modeled the potential cost of BP-MRI compared to MP-MRI to determine what cost savings would occur if DCE was eliminated from these studies. Results: When controlled for a 45 min time window that allows for one full MP-MRI or three full BP-MRI studies, the BP-MRI 45 min gross profit is $1531.32. This is an increase in gross profit of $892.58 for the 45 min time window or $10,710.98 in a 9-h business day when performing BP-MRI compared to MP-MRI for prostate cancer detection. Conclusions: BP-MRI has the potential to result in substantial cost benefit and increased access to MRI in the diagnostic workflow and risk-stratification of men being evaluated for prostate cancer when compared to conventional MP-MRI.
