Does the high-intensity zone (HIZ) of lumbar Intervertebral discs always represent an annular fissure?
HIZs on both T2- and T1-weighted images represent calcified tissue, possibly from a vertebral endplate. A new concept of dual HIZ should be defined.
These results suggest that the F/T PSA ratio is not helpful for the prediction of organ-confined disease and PSA recurrence after radical prostatectomy.
