Editor's Note ============= * Robert M. Quencer ## Editor’s Note: Inadvertently omitted from Dr. Aya Tokmaru’s letter which appeared in the May 2000 issue of the journal was the citation to a paper which she was referring to in the communication. The specific reference was: Kato T, Okuyama K. **Assessment of maturation and impairment of brain by I-123 iodoamphetamine SPECT and MR imaging in children.** *The Showa University Journal of Medical Sciences* 1993;5:99–115. Interested readers are referred both to her letter; (AJNR [2000]; 21:990), the above reference, and her article which appeared in the (*AJNR* [1999];20:845–852). Dr Kato would like to also draw our readers’ attention to the following reference: Kato T, Matuo T, Mikami I, Nose K. **Assessment of sagittal brain maturation and impairment in children with I-123 Iodoamphetamine SPECT.** *Radiology* (supp). 1992;85:107. Re: Tarang N, Luana “Pilon”, Jay Keystone, and Walter Kucharczyk. Persistent MR Contrast Enhancement of Calcified Neurocysticercosis Lesions. *AJNR Am J Neuroradiol* 19:79–82, January 1998. This is a formal request for correction of the spelling of the second author’s name, “Luana Pillon”. Correction of the surname of the second author should be “Pillon”. I appreciate your help in this matter. Dr. Luana Pillon * Copyright © American Society of Neuroradiology
