“…However, like the VIPR-SSFP sequence, the clinical accuracy of these new cartilage imaging MR pulse sequences has not yet been tested. The PD-FSE, T2-FSE, and SPGR sequences have all been found to be effective for evaluating the articular cartilage of the knee joint in large clinical studies with arthroscopic correlation (1)(2)(3)(4). For this reason, these sequences remain the gold standard with which all other cartilage imaging MR pulse sequences must be compared.…”

“…The proton density-weighted fast spinecho (PD-FSE), fat-suppressed T2-weighted fast spinecho (T2-FSE), and three-dimensional fat-suppressed spoiled gradient recalled-echo (SPGR) sequences are presently the most commonly used MR pulse sequences to evaluate articular cartilage. The accuracy of these sequences for detecting articular cartilage defects within the knee joint has been well documented in large clinical studies with surgical correlation (1)(2)(3)(4).…”

Purpose:To determine the feasibility of the vastly undersampled isotropic projection reconstruction steady-state free precession (VIPR-SSFP) sequence for evaluating the articular cartilage of the knee joint. Materials and Methods:A magnetic resonance (MR) examination of the knee was performed on 33 subjects using a GE 1.5T scanner and a phased-array extremity coil. VIPR-SSFP, proton density-weighted fast spin-echo (PD-FSE), fat-suppressed T2-weighted fast spin-echo (T2-FSE), and three-dimensional fat-suppressed spoiled gradient recall-echo (SPGR) sequences were performed on three asymptomatic volunteers and 10 patients with osteoarthritis of the knee joint. Signalto-noise efficiency, and contrast-to-noise ratio (CNR) measurements were calculated for all sequences and compared with the use of paired t-tests. The VIPR-SSFP sequence was then performed on 20 consecutive patients who were undergoing a routine MR examination of the knee. Results:The cartilage signal-to-noise efficiency of the VIPR-SSFP sequence was not significantly different from that of the PD-FSE and SPGR sequences. The cartilage signal-to-noise efficiency of the VIPR-SSFP sequence was significantly higher (P Ͻ 0.05) than that of the T2-FSE sequence. The VIPR-SSFP sequence produced images with significantly higher (P Ͻ 0.05) CNR between cartilage and synovial fluid than the PD-FSE and SPGR sequences, and significantly higher (P Ͻ 0.05) CNR between cartilage and subchondral bone than the T2-FSE sequence. The VIPR-SSFP sequence allowed excellent visualization of the articular cartilage of the knee joint in all subjects. All articular cartilage defects identified on the PD-FSE, T2-FSE, and SPGR images were well visualized on the VIPR-SSFP images.Conclusion: VIPR-SSFP images had high cartilage signalto-noise efficiency and high CNR between cartilage and adjacent synovial fluid and subchondral bone; therefore, the sequence is well suited for evaluating the articular cartilage of the knee joint.

“…Volunteers with a history of knee pain, trauma, or surgery were not included in the study. Because clinical symptoms are often weakly correlated with osteoarthritic lesions, and because cartilage lesions can be sufficiently detected with current protocols (Disler et al, 1995), the MR images were qualitatively read by an experienced radiologist. This led to the exclusion of three women and four men (Ͼ50 years old).…”

We tested the hypothesis that muscle cross-sectional areas (MCSAs) are more highly (and independently) correlated with cartilage morphology than are body height and weight, and that the physiological reduction of cartilage thickness with aging is associated with a proportional, age-dependent decrease in MCSAs. In 59 asymptomatic individuals (23-75 years old), morphological parameters of the knee cartilages (volume, thickness, and bonecartilage interface area), and MCSAs were determined from magnetic resonance imaging (MRI) data. Multiple regression models were used to calculate which proportion of the variability of the normal cartilage morphology can be predicted based on independent variables. MCSAs and body height and weight showed correlation coefficients of ϩ0.66, ϩ0.60, and ϩ0.25, respectively, with knee-joint cartilage volume. The correlation coefficients with cartilage thickness were ϩ0.44, ϩ0.35, and ϩ0.24, respectively. Age accounted for a significant (P Ͻ 0.01) reduction in cartilage thickness, but there was no proportional change of MCSAs. Approximately 76% of the variability of the knee cartilage volume could be predicted from independent variables in a multiple regression model with MCSAs contributing significant, independent information. In conclusion, we find that MCSAs are more highly correlated with cartilage morphology than are body height and weight. The significant decrease in cartilage volume and thickness with age is not associated with a proportional decrease in MCSAs. Anat Rec Part A 270A: 175-184, 2003.

“…Quantitative musculoskeletal imaging has been employed at standard field strengths to assist in the clinical diagnosis of diseases such as osteoarthritis (OA) and osteoporosis (OP), to monitor the progression of diseases and to evaluate response to treatment with structure/disease-modifying drugs [4][5][6][7]. The measurement of cartilage morphology may provide a biomarker for evaluating the long-term progression of OA.…”

To assess the reproducibility of quantitative measurements of cartilage morphology and trabecular bone structure of the knee at 7 T, high-resolution sagittal spoiled gradient-echo images and highresolution axial fully refocused steady-state free-precession (SSFP) images from six healthy volunteers were acquired with a 7-T scanner. The subjects were repositioned between repeated scans to test the reproducibility of the measurements. The reproducibility of each measurement was evaluated using the coefficient(s) of variation (CV). The computed CV were 1.13% and 1.55% for cartilage thickness and cartilage volume, respectively, and were 2.86%, 1.07%, 2.27% and 3.30% for apparent bone volume over total volume fraction (app.BV/TV), apparent trabecular number (app.Tb.N), apparent trabecular separation (app.Tb.Sp) and apparent trabecular thickness (app.Tb.Th), respectively. The results demonstrate that quantitative assessment of cartilage morphology and trabecular bone structure is reproducible at 7 T and motivates future musculoskeletal applications seeking the high-field strength's superior signal-to-noise ratio.
