상완신경총의 영상 진단은 복잡한 해부학적인 구조와 다양하게 침범하는 병들로 인해 어렵고 도전적이다. 상완신경총 영상 진단의 일차적인 목표는 외상성 손상과 비외상성 손상의구별이다. MRI의 급속경사와 전용표면코일을 이용한 적절한 공간분해능을 가진 영상기기의발전과 이를 이용한 다양한 펄스열의 개발이 상완신경총의 외상성 손상과 비외상성 손상에대한 구별에 많은 도움을 주어 정확한 진단으로 수술 여부의 결정에 이용된다. MRI는 비외상성 상완신경총 병변의 진단에 가장 좋은 영상진단이며, CT 척수강조영술은 상완신경총을침범하는 신경근견열 병변의 검사에 많이 이용된다. 그리고 일반적으로 고화질, 고해상력의MRI 가 상완신경총 비외상성병변의 진단에 일차적인 영상검사로 중요한 역할을 하고 있다.
Abstract
MR (magnetic resonance) imaging of the brachial plexus is challenging because of the complex and tangled anatomy of the brachial plexus and the multifariouness of pathologies that can put on it. Improvements in imaging techniques, including the availability of high resolution MR image systems and high channels multidetector computed tomography (CT), have led to more accurate diagnoses and improved serve for treatment planning. For the purpose of imaging and treatment of the brachioplexopathy, it is considerate to divide traumatic and nontraumatic diseases affecting the brachial plexus. MRI is the current gold standard imaging modality for nontraumatic brachial plexopathy. CT myelography is the preferred for the diagnosis of nerve root avulsions affecting the brachial plexus. Other modalities, such as CT, ultrasonography and positron emission tomography, have a limited role in the evaluation of brachial plexus pathology. High-quality, high-resolution MRI remains the main tool for imaging the brachial plexopathy.
