Abstract Silent magnetic resonance angiography (S-MRA) is primarily utilized to assess the blood flow in aneurysms and parent vessels of treated intracranial aneurysms. This study aimed to compare the diagnostic value of S-MRA and three-dimensional time of flight (3D-TOF) MRA for unruptured intracranial aneurysms. We included patients diagnosed with unruptured intracranial aneurysms using digital subtraction angiography (DSA) who subsequently underwent S-MRA and 3D-TOF MRA. Two independent neuroimaging and neurointerventional doctors evaluated the DSA images and measured aneurysm dimensions. Using DSA results as the gold standard, we determined the sensitivity and specificity of S-MRA and 3D-TOF MRA, as well as their accuracy in measuring aneurysm size and identifying aneurysms with daughter sacs. We detected a total of 41 intracranial aneurysms (in 37 patients) on both S-MRA and 3D-TOF MRA, with both techniques achieving a sensitivity and specificity of 100%. For aneurysm height, the intraclass correlation coefficient (ICC) was 0.977 (P
