Studies comparing diagnostic performance of WBMRI and PET-CT

Ref	First author	Year	Population	Use of DWI	Sensitivity of WBMRI (vs. PET-CT)	Specificity of WBMRI (vs. PET-CT)	Accuracy of WBMRI (vs. PET-CT)	Comments
[9]	Jacobs	2018	22 patients with stage IV	Yes	96% (vs. 80%)	N/R	N/R	ADC values were significantly increased in bone lesions while they were decreased in soft tissue metastases.
[107]	Schmidt	2007	30 patients with different stages	Yes	94% (vs. 78%)	76% (vs. 80%)	91% (vs. 78%)	WBMRI showed superior accuracy in bone marrow screening compared to PET-CT.
[86]	Antoch	2003	98 patients with different stages	No	90% (vs. 93%)	95% (vs. 95%)	93% (vs. 94%)	PET-CT showed better performance. However, the WBMRI was performed without DWI.
[89]	Schmidt	2008	33 patients with breast cancer and suspicious of recurrence	Yes	93% (vs. 91%)	86% (vs. 90%)	91% (vs. 91%)	It was also assessed that staging with WBMRI is feasible at 1.5 and 3 T, noting that scan time is reduced at 3 T with identical resolution.
