The Risk of Over‑Reliance on Weld Overlays in Phased Array Ultrasonic Testing Interpretation
e-Journal of Nondestructive TestingPhased array ultrasonic testing (PAUT) instruments often incorporate optional weld overlays that superimpose an assumed joint geometry on the sectorial scan (S‑scan). These overlays aid interpretation and scan planning by positioning signals relative to

Arthritis Care &Research, EarlyView.Objective Routine liver enzyme monitoring is advocated for while on allopurinol, but supporting guidance is lacking. We assessed the incidence and factors associated with elevated liver enzyme levels in patients with gout commenced on allopurinol. Methods One hundred and fifty patients with gout and normal baseline serum aminotransferases initiated on ...
