1 The zonal architecture of human articular cartilage described by T2 relaxation time in the presence of Gd-DTPA2−  Jatta E. Kurkijärvi, Mikko J. Nissi, Jarno Rieppo, Juha Töyräs, Ilkka Kiviranta, Miika T. Nieminen, Jukka S. Jurvelin  Magnetic Resonance Imaging  Volume 26, Issue 5, Pages (June 2008) DOI: /j.mri Copyright © 2008 Elsevier Inc.

2 Fig. 1 Characteristic polarized light microscopic BF image (A), reciprocal of BF (1/BF) (B), T2 (C) and T2Gd (D) maps of human knee articular cartilage. T2 maps are scaled between 16 ms (black) and 64 ms (white). Magnetic Resonance Imaging  , DOI: ( /j.mri ) Copyright © 2008 Elsevier Inc. Terms and Conditions

3 Fig. 2 Characteristic depth-wise T2, T2Gd and polarized light microscopic (1/BF) profiles of human knee articular cartilage. Magnetic Resonance Imaging  , DOI: ( /j.mri ) Copyright © 2008 Elsevier Inc. Terms and Conditions

5 Fig. 4 Depth-wise averaged (bulk) values of T2 as a function of T2Gd (A) and Bland–Altman plots for T2 and T2Gd (B). Continuous line: the mean of the difference; dashed lines: ±2 S.D. Magnetic Resonance Imaging  , DOI: ( /j.mri ) Copyright © 2008 Elsevier Inc. Terms and Conditions

6 Fig. 5 Mean thickness of superficial (I), intermediate (II) and deep (III) tissue zones of human articular cartilage, as assessed by polarized light microscope, T2 and T2Gd times (n=65). Kruskall–Wallis post hoc test showed significant differences (P<.01) in Zone I thickness as determined with PLM and MRI parameters.

7 Fig. 6 Linear correlation between zonal thicknesses, as assessed by T2 and T2Gd (n=65) in (A) superficial, (B) intermediate and (C) deep zones. Magnetic Resonance Imaging  , DOI: ( /j.mri ) Copyright © 2008 Elsevier Inc. Terms and Conditions

8 Fig. 7 Bland–Altman plots for laminar boundary locations as determined by T2 (A) or T2Gd (B) and polarized light microscope (1/BF) profiles. Mean difference of mm for the lamina boundary locations, as detected by T2 and T2Gd or PLM. Solid and dashed lines indicate the mean difference and ±2 S.D.
