Incorrect Units of Measure in Magnetic Resonance Imaging Study.—In the article entitled "Magnetic Resonance Imaging vs Palpation of Cervical Lymph Node Metastasis" that appeared in the June issue of the Archives (1991;117:666-673), errors appeared in the units of measurement for repetition time (TR) and echo time (TE) as well as flip angle. On page 667, column 1, the last line, the TR/TE flip angle appeared as follows: "285°/32°/8°"; it should have appeared as follows: "285 ms/32 ms/8°." On page 667, column 2, lines 6 and 7, the TR/TE flip angle appeared as follows: "95° to 126°/16° to 20°/45°"; it should have appeared as follows: "95 to 126 ms/16 to 20 ms/45°."
