Magnetic Resonance Imaging of Vascular Lesions in Children

Abstract

Ten children aged 1 week to 13 years with 12 vascular abnormalities were examined with magnetic resonance imaging (MRI) and other imaging modalities. MRI was the only single non-invasive modality that demonstrated all lesions and their internal structures. The vascular nature of 3 hemangiomas could not be established with MRI alone. No marked differences in MRI appearance was seen in 5 cases with vascular tumors compared with 5 cases with other vascular abnormalities. The status of the blood in the vascular lesions as flowing fast, slow, or not at all was successfully assessed in 9 of the 12 lesions.

Artifacts, variants, and factors degrading image quality in pediatric magnetic resonance imaging

“…Fletcher et al [3] indicate motion and non-visualization in 3 out of 19 patients (16%) with congenital cardiac malformations and an average age of 10years. Our recommendations from parts of the present material have been mentioned previously [4][5][6]. The methods of immobilization and sedation used have been similar to those employed for pediatric CT examinations.…”

History of surgery for cerebrovascular disease in children. Part I. Intracranial arterial aneurysms

“…The emergence of CT and MR imaging studies obtained with contrast agents has allowed noninvasive, detailed characterization of aneurysms and the structures surrounding them. 60,78 The development and widespread adoption of digital subtraction angiographic techniques occurred during the late 1970s and early 1980s. 79 There were also very significant advances in microneurosurgical techniques during this time that revolutionized the treatment of intracranial aneurysms in adults.…”
