In the article “A New Era of Clinical Dopamine Transporter Imaging Using 123I-FP-CIT,” by Park (J Nucl Med Technol. 2012;40:222–228), the key was inadvertently omitted from Figure 1. In the figure, closed circles represent striatum; open circles, occipital cortex; and triangles, midbrain. The author regrets the error.
The figure citations are incorrect in “Brain SPECT Imaging with Acetazolamide Challenge,” by Johnston (J Nucl Med Technol. 2013;41:52–54, 10A). In the paragraph describing the balloon angioplasty procedure, Figure 3 should have been cited instead of Figure 1; in Question 2, Figures 1 and 2 should have been cited instead of 2 and 3. We regret the error.
In Figure 4 of “The Value of Observer Performance Studies in Dose Optimization: A Focus on Free-Response Receiver Operating Characteristic Methods,” by Thompson et al. (J Nucl Med Technol. 2013;41:57–64), panels A and B were labeled as 18F bone scans and C and D as 99mTc-methylene diphosphonate scans whereas, in fact, the opposite is true. We regret the error.
Dr. Lars Jodal, medical physicist in the Department of Nuclear Medicine, Aalborg University Hospital, Denmark, has pointed out some errors in “99mTc-Mercaptoacetyltriglycine Camera-Based Measurement of Renal Clearance: Should the Result Be Normalized for Body Surface Area?” by Klingensmith (J Nucl Med Technol. 2013;41:279–282). The unit “min” was omitted from the denominator of the left side of Equation 4. In addition, the time factor, “t (min),” was omitted from the denominator of the right side of the same equation and from the denominator of the right side of Equations 5 and 8 as well. Consequently, there should be an extra factor of “1” in the denominator of Equations 6 and 9. However, these omissions do not affect the reasoning or conclusions of the paper. The author regrets the errors.
