Diagnostic Value of <sup>123</sup>I-Ioflupane and <sup>123</sup>I-Iodobenzamide SPECT Scans in 248 Patients with Parkinsonian Syndromes

Abstract

FP-CIT SPECT is accurate to differentiate patients with IPD from those with ET, and IPD from VP and DIP. The accuracy of both FP-CIT and IBZM SPECT scans to differentiate between IPD and APS is low.
