Maximum intensity projection ¹⁸F-FLT PET images of MDS patients (a–d). MDS patients exhibited marked ¹⁸F-FLT uptake in the central skeleton and proximal extremities (a, b). On the other hand, hypo-MDS patients who were defined by having decreased ¹⁸F-FLT uptake in the pelvis exhibited a slightly decreased uptake of the tracer in the vertebrae and ribs (c, d). ¹⁸F-FLT PET did not reveal any significant differences between patients with sustained MDS or overt AML
