Evaluation of T1ρ relaxation times in meniscal tears during static loading

Accuracy of SPECT bone scintigraphy in diagnosis of meniscal tears

Introduction: Scintigraphy has been considered as a useful tool in the assessment of meniscal tears. Our objective was to assess the accuracy of single photon emission tomography (SPECT), using MRI as the gold standard, in the diagnosis of meniscal tears. Materials and Methods: Between January 2003 and February 2005, 45 patients were studied with SPECT and MRI. Results: The respective sen...

Meniscal tears

The menisci are two semilunar-shaped fibrocartilagenous structures, which are interposed between the femoral condyles and tibial plateaux. They have an important role in knee function. Long-term follow-up studies showed that virtually all meniscectomized knees develop arthritic changes with time. The meniscus has functions in load bearing, load transmission, shock absorption, joint stability, j...

Surgical management of meniscal tears.

The menisci have an essential function in force transmission across the knee. Injuries to the menisci are common. The indications for repair should be expanded, as the results of partial meniscectomy may deteriorate over time. Tears in younger, higher demand patients should be prepared to optimize the healing environment and be meticulously repaired, particularly in the setting of concurrent an...

Rapid Quantification of Systolic and Diastolic Transverse T1ρ Relaxation Times in the Human Left Ventricle

diastole (A1-A4) and in systole (B1-B4). All images were acquired from a single healthy subject scanned four separate times. Figure 1: Method for KWIC reconstruction of T1ρ data. Undersampled radial images were acquired during which the spin lock duration (TSL) was varied in each (Columns 1 and 2). During KWIC reconstruction, high spatial frequency components with a minimum kspace radius kmin w...
