Figure 3. Representative Examples of Image Quality on Sagittal T2- and T1-Weighted Sequences of the Lumbar Spine.

Figure 3

Top row: sagittal T2-weighted turbo spin-echo sequences of the lumbar spine of four patients, representing the range of qualitative image quality scores obtained with short-bore (A, C) and open MR imaging (B, D). Overall image quality ratings were: “optimal” for A,“good” for B, “moderate” for C, and “poor” for D. No sequence was rated very poor (nondiagnostic). Bottom row: sagittal T1-weighted turbo spin-echo sequences of the lumbar spine of the same four patients obtained with short-bore (E, G) and open MR imaging (F, H). Overall image quality ratings were: “good” for sequence E,“moderate” for F, “good” for G, and “poor” for H. No sequence was rated very poor (nondiagnostic).
