Skin tumors were staged at magnetic resonance (MR) imaging on a 0.5-T (middle-field-strength) system, with use of a 2-cm-diameter receive-only surface coil. T1- and T2-weighted spin-echo (SE), fast SE, or three-dimensional (3D) spoiled gradient-recalled imaging were performed in three volunteers and in 13 patients with skin tumors (nine, basal cell carcinoma). MR findings correlated well with histologic findings in the patients (epidermis, relatively hyper-intense on all images; dermis, hypo-intense with irregular interface with subdermal fat). 3D images had the optimal combination of tissue contrast, signal-to-noise ratio, and spatial resolution. MR imaging depicts depth of skin tumor invasion, and findings are complementary to clinical staging.
皮肤肿瘤在0.5-T（中场强）系统上进行磁共振（MR）成像分期，使用直径2厘米的仅用于接收的表面线圈。对3名志愿者和13名患有皮肤肿瘤（9例基底细胞癌）的患者进行了T1加权和T2加权自旋回波（SE）、快速SE或三维（3D）扰相梯度回波成像。患者的MR表现与组织学表现相关性良好（表皮在所有图像上相对高信号；真皮低信号，与皮下脂肪界面不规则）。3D图像在组织对比度、信噪比和空间分辨率方面具有最佳组合。MR成像可描绘皮肤肿瘤的浸润深度，其表现对临床分期具有补充作用。
