Results
A thin triangular cotton bandage showed no visible artefacts. In a group of patients in whom the adipose tissue was elevated, the thickness around the waist decreased by 4.7% after tissue displacement (p<0.001), while the hip circumference remained the same (p=0.211). In the tissue displacement group, DAP was 38.5% lower (p=0.001), ESD was 44% lower (p<0.001), and effective dose was 38.7% lower (p<0.001), see Figure 2, 3 & 4. Hip joints (p=0.001), trochanters (p=0.021), acetabula (p<0.001), femoral necks (p=0.021), medulla and cortex of the pelvis (p=0.009), pelvic/hip soft tissues (p=0.039) and sacrum and its foramina (p=0.008) were better visualised on images acquired with adipose tissue displacement. However, we found no statistically significant differences between groups in visualisation of sacroiliac joints (p=0.055), iliac crests (p=0.060), and the pubic/ischial rami (p=0.166). In general, image quality was better in the tissue displacement group (Figure 5), as the total image score showed statistically significant differences between groups (p=0.004), see Figure 6.
