While MR is known to be superior to other imaging methods for detecting marrow involvement by lymphoma, MR is also capable of detecting abnormal lymph nodes. Our objective was to determine whether MR employing short TI inversion recovery (STIR) was comparable to CT in the initial staging of 23 patients with Hodgkin's disease (12 patients) and non-Hodgkin's lymphoma (11 patients). MR images of chest, abdomen, pelvis, and femoral marrow were obtained using the STIR and T1-weighted spin-echo (T1-SE) techniques, employing a protocol initially designed for marrow assessment. In all cases, CT-detected adenopathy was also found by MR. Four patients had marrow involvement by MR, undetected by CT. We conclude that MR and CT may be equivalent imaging modalities in the detection of nodal involvement, and that MR has an advantage in its ability to diagnose marrow involvement. Given the high frequency of focal marrow abnormalities detected by MR in patients with Hodgkin's disease and high-grade non-Hodgkin's lymphoma, MR may be the preferred staging modality for these patients.
虽然已知磁共振成像（MR）在检测淋巴瘤骨髓受累方面优于其他成像方法，但MR也能够检测异常淋巴结。我们的目的是确定采用短TI反转恢复（STIR）序列的MR在23例霍奇金病（12例）和非霍奇金淋巴瘤（11例）患者的初始分期中是否与CT相当。使用STIR和T1加权自旋回波（T1-SE）技术获取胸部、腹部、骨盆和股骨骨髓的MR图像，采用最初为骨髓评估设计的方案。在所有病例中，MR也发现了CT检测到的淋巴结肿大。4例患者存在MR检测到的骨髓受累，CT未检测到。我们得出结论，在检测淋巴结受累方面，MR和CT可能是等效的成像方式，并且MR在诊断骨髓受累的能力方面具有优势。鉴于在霍奇金病和高级别非霍奇金淋巴瘤患者中MR检测到的局灶性骨髓异常频率较高，MR可能是这些患者首选的分期方式。
