Motivation: Quantitative nidus volume measurement of cerebral arteriovenous malformation（CAVM）is of great important for the CAVM treatment management.
Goal(s): This study aims to investigate non-invasive nidus volume measurement of CAVM with silent MRA and explore the difference between silent MRA and TOF-MRA.
Approach: Nidus volume was measured by silent MRA, TOF-MRA, and digital subtraction angiography（DSA）. Nidus volume measured by DSA was regarded as golden standard.
Results: Silent MRA can accurately measure the nidus volume of CAVM. There is a significant difference in nidus volume measurement between silent MRA and TOF-MRA, silent MRA also has advantage for CAVM patients treated by embolization.
Impact: As a non-invasive and contrast agent-free MRA imaging technology, silent MRA can be used as an effective and accurate imaging tool for nidus volume measurement and as a follow-up tool for nidus volume change evaluation after surgery, embolization, and radiotherapy.
