AI Article Synopsis
- The study explored the effectiveness of fusing 3D digital subtraction angiography (DSA) and magnetic resonance (MR) images to enhance visualization of cerebral arteriovenous malformations (AVM).
- Seven patients underwent this imaging technique prior to various treatments, allowing for a comprehensive view of the AVM and surrounding structures.
- The fusion images assisted in surgical planning by clarifying the relationship between the AVM and nearby anatomy, making it easier for neurosurgeons to prepare for surgery.
Article Abstract
Aim: An image fusion of 3-dimensional (D) digital subtraction angiography (DSA) and magnetic resonance (MR) images, DSA-MR fusion, can simultaneously visualize both information of the vasculature provided by 3D DSA and of the soft tissues provided by MR images. The authors assessed the usefulness of DSA-MR fusion images concerning the pretreatment evaluation for cerebral arteriovenous malformation (AVM).
Material And Methods: Seven consecutive patients underwent pretreatment DSA-MR fusion and then microsurgical, endovascular and/ or radiosurgical treatments.
Results: DSA-MR fusion images clearly showed the spatial relationship among AVM, its feeding artery, draining vein, surrounding artery feeding the normal brain tissue, hematoma and brain tissues (gyri or brain surface) with reasonable post-processing time.
Conclusion: These findings were useful for treatment planning for AVM, especially to enable neurosurgeons to easily understand the surgical anatomy preoperatively.

Cerebral micro-arteriovenous malformations (AVM) are defined by an infracentimetric nidus or a nidus solely visible on superselective digital subtraction angiography (DSA). While representing a minority of brain AVMs, intracerebral hemorrhage is a frequent manifestation in this subset of AMVs. Micro-AVMs are often occult lesions, with superselective DSA being instrumental for increasing diagnostic yield.

We herein reported a patient with acute ischemic stroke in the bilateral medial medullary and the left tegmentum of the pons who presented with various neurological symptoms. Fusing digital subtraction angiography (DSA) and MRI (DSA-MR fusion imaging) could reveal the infarct-relevant arteries. A 41-year-old male presented with headache, bilateral arm's dysesthesia, quadriplegia, left Horner's syndrome, upbeat nystagmus, internuclear ophthalmoplegia and left peripheral facial paralysis.

We herein experienced one patient with typical branch atheromatous disease (BAD) type infarction. Digital subtraction angiography (DSA) and MRI fusion imaging revealed the relationship between atheromatous plaque and perforating branches. A 66-year-old male presented acute onset of dysarthria, the left side hemiparesis and sensory disturbance.

Rationale And Objectives: For the evaluation of patients scheduled for the treatment of brain arteriovenous malformations (AVMs), accurate anatomical information is essential. The purpose of this study was to assess the usefulness of three-dimensional (3D) digital subtraction angiography (DSA)-magnetic resonance (MR) fusion imaging for the pretreatment evaluation of AVMs.
Materials And Methods: The study population consisted of 11 consecutive patients (7 males, 4 females; age 10-72 years; mean 45 years) with brain AVMs.
