Magnetic resonance imaging has far-reaching real and possible clinical applications. Its usefulness has been best explored and realized in the central nervous system, especially the posterior fossa and brain stem, where most abnormalities are better identified than with computed tomography. Its lack of ionizing radiation and extreme sensitivity to normal and abnormal patterns of myelination make magnetic resonance imaging advantageous for diagnosing many neonatal and pediatric abnormalities. New, reliable cardiac gating techniques open the way for promising studies of cardiac anatomy and function. The ability to image directly in three orthogonal planes gives us new insight into staging and follow-up of pelvic tumors and other pelvic abnormalities. Exquisite soft tissue contrast, far above that attainable by other imaging modalities, has made possible the early diagnosis of traumatic ligamentous knee injury, avascular necrosis of the hip and diagnosis, treatment planning and follow-up of musculoskeletal neoplasms.
磁共振成像在临床有着广泛的实际应用和潜在应用。其效用在中枢神经系统，尤其是后颅窝和脑干中得到了最好的探索和体现，在这些部位，大多数异常情况通过磁共振成像比通过计算机断层扫描能得到更好的识别。磁共振成像不存在电离辐射，且对正常和异常的髓鞘形成模式极为敏感，这使得它在诊断许多新生儿和儿科异常情况时具有优势。新的、可靠的心脏门控技术为开展有前景的心脏解剖结构和功能研究开辟了道路。能够在三个相互垂直的平面上直接成像，让我们对盆腔肿瘤和其他盆腔异常情况的分期及随访有了新的认识。其出色的软组织对比度远超其他成像方式所能达到的水平，这使得早期诊断创伤性膝关节韧带损伤、髋关节缺血性坏死以及对肌肉骨骼肿瘤进行诊断、治疗规划和随访成为可能。
