Technical advances in MRI have improved image quality and have led to expanding clinical indications for its use. However, long examination and interpretation times, as well as higher costs, still represent barriers to use of MRI. Abbreviated MRI protocols have emerged as an alternative to standard MRI protocols. These abbreviated MRI protocols seek to reduce longer MRI protocols by eliminating unnecessary or redundant sequences that negatively affect cost, MRI table time, patient comfort, image quality, and image interpretation time. However, the diagnostic information is generally not compromised. Abbreviated MRI protocols have already been used successfully for hepatocellular carcinoma screening, for prostate cancer detection, and for screening for nonalcoholic fatty liver disease as well as monitoring patients with this disease. It has been reported that image acquisition time and costs can be considerably reduced with abbreviated MRI protocols, compared with standard MRI protocols, while maintaining a similar sensitivity and accuracy. Nevertheless, multiple applications still need to be explored in the abdomen and pelvis (eg, surveillance of metastases to the liver; follow-up of cystic pancreatic lesions, adrenal incidentalomas, and small renal masses; evaluation of ovarian cysts in postmenopausal women; staging of cervical and uterine corpus neoplasms; evaluation of müllerian duct anomalies). This article describes some successful applications of abbreviated MRI protocols, demonstrates how they can help in improving the MRI workflow, and explores potential future directions. RSNA, 2019.
MRI 技术的进步提高了图像质量，并扩大了其临床应用范围。然而，较长的检查和解释时间以及较高的成本仍然是 MRI 使用的障碍。缩短 MRI 方案已成为标准 MRI 方案的替代方案。这些缩短的 MRI 方案旨在通过消除对成本、MRI 台时间、患者舒适度、图像质量和图像解释时间产生负面影响的不必要或多余的序列来缩短较长的 MRI 方案。然而，诊断信息通常不会受到影响。缩短的 MRI 方案已成功用于肝细胞癌筛查、前列腺癌检测以及非酒精性脂肪性肝病的筛查以及监测此类疾病的患者。据报道，与标准 MRI 方案相比，缩短的 MRI 方案可以大大减少图像采集时间和成本，同时保持相似的敏感性和准确性。然而，在腹部和骨盆中仍需要探索多种应用（例如，监测肝转移；随访囊性胰腺病变、肾上腺偶发瘤和小肾肿块；评估绝经后妇女的卵巢囊肿；分期宫颈和子宫体肿瘤；评估苗勒管异常）。本文介绍了缩短 MRI 方案的一些成功应用，展示了它们如何有助于改进 MRI 工作流程，并探讨了潜在的未来方向。RSNA，2019 年。
