“…14, 28-30 However, 3-D-MRA has been noted to be heavily affected by clip artifact as well as not allowing temporal resolution of an AVM. 14 In addition, 3-D-MRA has a significantly lower spatial resolution than DSA 31, 32 . For these reasons, DSA has remained the gold standard for operative planning for stereotactic radiosurgery.…”

Background The effectiveness of Gamma Knife radiosurgery (GKR) for cerebral arteriovenous malformations (AVM) is predicated on inclusion of the entire nidus while excluding normal tissue. As such, GKR may be limited by the resolution and accuracy of the imaging modality used in targeting. Objective We present the first case series to demonstrate the feasibility of utilizing ultra-high-resolution C-arm cone beam computed tomography angiography (CBCT-A) in AVM targeting. Methods From June 2009 to June 2013, CBCT-A was utilized for targeting of all patients with AVMs treated with GKR at our institution. Patients underwent Leksell stereotactic head frame placement followed by catheter-based biplane 2-D digital subtraction angiography (DSA), 3-D rotational angiography (3DRA), as well as CBCT-A. The CBCT-A dataset was used for stereotactic planning for GKR. Patients were followed up at 1, 3, 6, and 12 months, and then annually thereafter. Results CBCT-A-based targeting was used in twenty-two consecutive patients. CBCT-A provided detailed spatial resolution and sensitivity of nidal angioarchitecture enabling treatment. The average radiation dose to the margin of the AVM nidus corresponding to the 50% percent isodose line was 15.6 Gy. No patient had treatment-associated hemorrhage. At early follow-up (mean=16 months), 84% of patients had a decreasing or obliterated AVM nidus. Conclusion CBCT-A-guided radiosurgery is feasible and useful because it provides sufficient detailed resolution and sensitivity for imaging brain AVMs.

“…This finding may suggest that conventional catheter angiography is more suitable for pretreatment study of AVMs because the assessment of small vessel branches is essential in choosing the appropriate clinical management. 6 In certain cases, however, the noninvasive, radiation-free, and iodinated contrast agent-free nature of MR digital subtraction angiography may justify its use over conventional catheter angiography, particularly in screening and follow-up.
