“…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.

Objective. To evaluate the change in osteoarthritic (OA) knee cartilage volume over a two-year period with the use of magnetic resonance imaging (MRI) and to correlate the MRI changes with radiologic changes.Methods. Thirty-two patients with symptomatic knee OA underwent MRI of the knee at baseline and at 6, 12, 18, and 24 months. Loss of cartilage volumes were computed and contrasted with changes in clinical variables for OA and with standardized semiflexed knee radiographs at baseline at 1 and 2 years.Results. Progression of cartilage loss at all followup points was statistically significant (P < 0.0001), with a mean ؎ SD of 3.8 ؎ 5.1% for global cartilage loss and 4.3 ؎ 6.5% for medial compartment cartilage loss at 6 months, 3.6 ؎ 5.1% and 4.2 ؎ 7.5% at 12 months, and 6.1 ؎ 7.2% and 7.6 ؎ 8.6% at 24 months. Discriminant function analysis identified 2 groups of patients, those who progressed slowly (<2% of global cartilage loss; n ‫؍‬ 21) and those who progressed rapidly (>15% of global cartilage loss; n ‫؍‬ 11) over the 2 years of study. At baseline, there was a greater proportion of women (P ‫؍‬ 0.001), a lower range of motion (P ‫؍‬ 0.01), a greater circumference and higher level of pain (P ‫؍‬ 0.05) and stiffness in the study knee, and a higher body mass index in the fast progressor group compared with the slow progressor group. No statistical correlation between loss of cartilage volume and radiographic changes was seen.Conclusion. Quantitative MRI can measure the progression of knee OA precisely and can help to identify patients with rapidly progressing disease. These findings indicate that MRI could be helpful in assessing the effects of treatment with structure-modifying agents in OA.In people over the age of 60 years, osteoarthritis (OA) is a common cause of disability. Assessment of cartilage damage is important for monitoring disease progression and evaluating therapeutic response in OA. For many years, clinical studies of drug interventions in symptomatic knee OA have focused specifically on clinical parameters, such as pain and joint function, without assessing the effect of treatment on structural changes caused by the disease or the role of treatment in preventing cartilage degradation. Serial radiographs of affected joints appear to be a logical means of documenting the progression of OA over time (1), provided that a validated, reliable, and easily reproducible technique is used (2-5).
