“…[16][17][18] Thus, in the earliest phases of the erosion process, soft tissue changes of infl ammation should be present before focal loss of bone calcium. Thus, theoretically, MRI should detect changes of cellular infi ltrate or marrow edema before X-ray techniques can detect calcium loss, an assumption consistent with the literature.…”

The objective of this study was to compare standard hand radiographs with in-office 0.2 T magnetic resonance imaging (MRI) in monitoring response to therapy in patients with rheumatoid arthritis (RA) who were receiving infliximab, to evaluate the frequency and location of erosions, and to determine if there were differences in outcome based on disease duration at baseline. Patients who satisfied the American College of Rheumatology criteria for RA and were receiving infliximab therapy were evaluated with a baseline and 1-year follow-up MRI. Magnetic resonance images were interpreted by two blinded, board-certified radiologists. Bone erosions were identified as well-defined defects extending through the cortical margin. The mean age of the 48 patients was 58.5 years. The median infliximab dosage was 4 mg/kg. Baseline data showed that 41 patients had abnormal MRIs. The mean time between the baseline and follow-up MRI examinations was 10.5 months. Follow-up MRI revealed regression in 11 patients. Thirty-one patients had both MRIs and radiographs. Magnetic resonance imaging was approximately twice as sensitive as radiography in detecting erosions at baseline. In-office MRI was useful in monitoring disease response after the initiation of infliximab treatment. Magnetic resonance imaging is potentially a very valuable diagnostic tool and prognostic indicator for use in patients with RA.

“…Fat suppression (FS) requires a homogeneous field and high magnetic field strengths, which are not available in low-field units [6]. The only FS technique possible in E-MRI units is short T1 inversion recovery (STIR), based on relaxation time differences, which can provide comparable information on bone marrow oedema (BME), although with fewer details [6].…”

“…The only FS technique possible in E-MRI units is short T1 inversion recovery (STIR), based on relaxation time differences, which can provide comparable information on bone marrow oedema (BME), although with fewer details [6]. However, new E-MRI units are emerging, operating at 1–1.2 T field strength.…”

“…Fat and Gd-enhanced tissue has a high signal intensity on T1-weighted images and, since Gd uptake depends on tissue vascularity and perfusion, the highly vascularised and perfused inflamed synovium is easily recognisable [6]. In T1FS post-Gd images, FS increases the contrast between the inflamed synovium and adjacent structures [6]. This make inflammatory changes more easily recognisable.…”

Magnetic resonance (MR) is used more and more frequently to diagnose changes in the musculoskeletal system in the course of rheumatic diseases, at their initial assessment, for treatment monitoring and for identification of complications. The article presents the history of magnetic resonance imaging, the basic principles underlying its operation as well as types of magnets, coils and MRI protocols used in the diagnostic process of rheumatic diseases. It enumerates advantages and disadvantages of individual MRI scanners. The principles of MRI coil operation are explained, and the sequences used for MR image analysis are described, particularly in terms of their application in rheumatology, including T1-, T2-, PD-weighted, STIR/TIRM and contrast-enhanced T1-weighted images. Furthermore, views on the need to use contrast agents to optimise diagnosis, particularly in synovitis-like changes, are presented. Finally, methods for the assessment of MR images are listed, including the semi-quantitative method by RAMRIS and quantitative dynamic examination.
