OBJECTIVES The purpose of this study was to compare the results of magnetic resonance angiography (MRA) with X-ray coronary angiography (XCA) in a pediatric population. BACKGROUND Coronary artery abnormalities in Kawasaki disease (KD) develop in about 15% to 25% of young patients, mostly in the form of aneurysms. METHODS Thirteen patients (12 male), age three to eight years, were studied. T...

Multiple imaging modalities are available to evaluate aneurysms post-flow diverter (FD) placement. Though digital subtraction angiography (DSA) is the gold standard imaging modality post-FD placement, it is not perfect, and neither are other techniques, including contrast-enhanced magnetic resonance angiography (CE-MRA) and magnetic resonance imaging (MRI). We present a case of a 73-year-old wo...

A 62-year-old man was admitted to our hospital with a brain infarction in the right medulla. On the first day, he was diagnosed with a vertebral artery dissection, based on the findings from conventional angiography, which showed an irregular stenosis associated with a pseudoaneurysm of the right vertebral artery (Picture 1). This finding on classical angiography is called the pearl and string ...

Magnetic resonance angiography (MRA) is increasingly used to evaluate arterial and venous diseases. Although the resolution of MRA is not as high as that of conventional angiography, it is sufficient to evaluate pathologic conditions in the larger vascular structures of most parts of the body. It is especially useful in patients who cannot tolerate the risks of iodinated contrast agents or arte...

Introduction: Ghost magnetic resonance angiography (MRA) is a new method for angiography that suppresses background tissue without subtraction. The method is predicated on the creation of arterial ghost artifacts within a region containing no MR signal (e.g. air), and can be used for both unenhanced and contrast-enhanced MRA. When used for unenhanced MRA, cardiac gating is not required. This ca...

A 66-year-old man presented with typical trigeminal neuralgia (TN). Magnetic resonance angiography (MRA) revealed a primitive trigeminal artery (PTA) that came into contact with the trigeminal nerve. Based on MRA, we performed microvascular decompression (MVD). In the operational field, we confirmed the PTA location and performed MVD successfully. Postoperatively, the patient's pain subsided wi...

OBJECTIVES/HYPOTHESIS Pulsatile tinnitus in the face of normal findings on otoscopy is a common otological diagnostic dilemma and can be due to serious vascular malformations such as transverse or sigmoid sinus dural arteriovenous fistula (transverse or sigmoid sinus [TS] DAVF). Left untreated, TS DAVF may result in significant morbidity and mortality. TS DAVF can be suspected or diagnosed with...

BACKGROUND AND PURPOSE Present criteria for the diagnosis of moyamoya disease emphasize the use of conventional cerebral angiography as an indispensable requirement. However, magnetic resonance angiography (MRA) is fast becoming a reliable diagnostic modality for occlusive cerebrovascular diseases. The purpose of this study is to assess the accuracy of MRA compared with conventional angiography...

Extracranial-intracranial (EC-IC) bypass operation may be performed to augment the distal cerebral circulation. The bypass patency is usually assessed postoperatively with conventional cerebral angiography. Six patients are reported in whom the bypass patency was assessed using magnetic resonance angiography (MRA): Two had intracavernous carotid aneurysms, three had base of skull tumours encomp...
