Line scanning of a representative hair sample from patients treated with PDs. Two indentical peaks in the hair (1, 2) were obtained for both ¹⁹⁴Pt and ¹⁹⁵Pt in this patient treated with PDs. Peaks reflect the administration of PDs. Estimated: days before the hair sampling that were estimated by measuring the distance from the follicle to platinum peaks, based on an average growth rate of 10 mm/month. Administration of PDs: days before the hair samplings that were noted in clinical records of PD administration
