Quantitative Cartilage Imaging in Knee Osteoarthritis
Figure 2
Sagittal 3D DESS MR images showing anatomical regions of interest commonly analyzed: (a) lateral femorotibial compartment, (b) medial femorotibial compartment; P: patella, TrF: femoral trochlear, MT: medial tibia, MF: medial femoral condyle, cMF: weight-bearing part of the medial femoral condyle, pMF: posterior part of the medial femoral condyle, MFTC: cMF + MT; LT: lateral tibia, LF: lateral femoral condyle, cLF: weight-bearing part of the lateral femoral condyle, pMF: posterior part of the lateral femoral condyle, LFTC: cLF + LT; the magental line shows the projection of the trochlear notch, the blue line the posterior end of the medial and lateral femoral condyle, and the turquoise line the 60% criterion (of the distance between the trochlear notch and the posterior ends of the condyles) used to separate cMF from pMF, and cLF from pLF, respectively. Images are from the Osteoarthritis Initiative (OAI), a public-private partnership funded by the National Institutes of Health and conducted by the OAI Study Investigators. For anatomical (region of interest) labels, also see Figure 1 and Table 1.
