Table III.

Baseline organ iron burden in TWiTCH as assessed by abdominal R2*. Pancreas, kidneyand spleen values are expressed in Hertz; liver iron concentration (LIC) is not expressed in Hertz because the scale factors are not exactly known.

Organ	N	Mean ± SD [Range]	Normal Range	Percentage Abnormal	Percentage Mild
LIC_R2* (mg/g)	121	9.0 ± 6.6 [1.5, 38.6]	< 1.3	100%	47.9% (≤ 7 mg/g)
Pancreas R2* (Hz)	120	28.9 ± 8.9 [19, 73.9]	< 28.1	38.3%	38.3% (< 100 Hz)
Kidney R2* (Hz)	119	80.6 ± 63.7 [13.3, 396.8]	< 32	80.7%	Not defined
Spleen R2* (Hz)	81	509 ± 399 [52, 1782]	< 35	100%	Not defined
