Figure 2. From: Sensitivity to Change of Cartilage Morphometry Using Coronal FLASH, Sagittal DESS, and Coronal MPR DESS Protocols - Comparative Data from the Osteoarthritis Initiative (OAI).

Correlation between the longitudinal changes of cartilage thickness in the medial femorotibial compartment (MFTC). The correlation of the change in cartilage thickness (ThC.tAB in mm) between baseline and year 1 followup is shown for A) the coronal (cor) FLASH and the cor multiplanar reconstruction (MPR) of the DESS, B) the cor FLASH and the sagittal (sag) DESS (60% region of interest of the femoral condyle), and C) for the cor MPR DESS and the sag DESS. The continous lines show the smallest detectable difference (SDD) for each imaging protocol based on previously published test-retest precision errors for paired readings.

Figure 1. From: Sensitivity to Change of Cartilage Morphometry Using Coronal FLASH, Sagittal DESS, and Coronal MPR DESS Protocols - Comparative Data from the Osteoarthritis Initiative (OAI).

Bland-Altman plots showing the differences (errors in mm) between the baseline cartilage thickness values of the different imaging protocols in the medial femorotibial compartment (MFTC) in relation to the mean value of the baseline cartilage thickness in the MFTC. The plot shows the relation between A) the coronal (cor) FLASH and the cor multiplanar reconstruction (MPR) of the DESS, B) the cor FLASH and the sagittal (sag) DESS (selecting a 60% region of interest of the femoral condyle), and C) for the cor MPR DESS and the sag DESS. The mean difference is indicated by the continous line, the limits of agreement (± 1.96 times the standard deviation of the difference) are indicated by dotted lines.
