January 30, 2004   MR Image–based Grading of Lumbar Nerve Root Compromise due to Disk Herniation: Reliability Study with Surgical Correlation - Radiology A system for grading lumbar nerve root compromise (no compromise, contact of disk material with nerve root, deviation of nerve root, and compression of nerve root) was tested in the interpretation of routine magnetic resonance images of 500 lumbar nerve roots in 250 symptomatic patients... January 22, 2004   Magnetic resonance imaging of sacroiliitis in early seronegative spondylarthropathy. Abnormalities correlated to clinical and laboratory findings - Rheumatology Conclusions: In patients with early SpA, MRI was able to detect inflammatory and destructive changes of the SIJs, but the changes were not associated to clinical findings. Our results suggest a role of MRI in the detection of early-stage sacroiliitis... January 20, 2004   MR Imaging and MR Arthrography of the Postoperative Shoulder: Spectrum of Normal and Abnormal Findings - Radiographics The postoperative shoulder may be evaluated with various imaging modalities, including radiography, ultrasonography, computed tomography, and magnetic resonance (MR) imaging, each of which has advantages and disadvantages. For optimal soft-tissue visualization, MR imaging and MR arthrography are widely used. Several factors, however, may decrease the accuracy of MR imaging in the evaluation of the postoperative shoulder...

January 16, 2004   Magnetic resonance evaluation of the interrelationship between articular cartilage and trabecular bone of the osteoarthritic knee - Osteoarthritis and Cartilage Conclusion: Degradation of articular cartilage within a compartment correlates with a loss of bone structure in the opposite compartment. The correlation between the (L-M) differences corroborates this relationship. Malalignment of the knee due to cartilage degeneration is associated with bone formation in the diseased condyle and bone resorption in the opposite compartment... January 15, 2004   Extramedullary fat fluid level on MRI as a specific sign for osteomyelitis - Australasian Radiology The role of MR in the early diagnosis of acute osteomyelitis is well known. In the context of florid cellulitis, abnormalities of marrow signal are not uncommon, although they are often non-specific. Marrow oedema and enhancement in the context of deep cellulitis might reflect either reactive marrow oedema or true osteomyelitis. More specific signs lend favour to the diagnosis of osteomyelitis: these include focal bone destruction, periosteal reaction and sequestra. The observation of an extramedullary fat-fluid sign is also a specific sign for osteomyelitis, as illustrated in the following case report...   Measurement of Trabecular Bone Mineral Density in the Thoracic Spine Using Cardiac Gated Quantitative Computed Tomography - Journal of Computer Assisted Tomography Conclusions: Cardiac gated CT, primarily intended for measurement of coronary vascular calcium, can be used to measure thoracic BMD with high precision. Thoracic BMD measurements using this method are highly correlated with QCT measurements in the lumbar spine...

January 12, 2004   Evaluation of the Commission of the European Communities quality criteria for the paediatric lateral spine - British Journal of Radiology The study aimed to evaluate the Commission of the European Communities (CEC) quality criteria for paediatric lateral spine radiographs, and to use these to assess and compare the quality of film–screen and digital images. 286 paediatric lateral spine radiographs (89 film–screen and 197 digital) were independently analysed by two observers according to the CEC criteria. Based on fulfilment of criteria, images were assigned two scores, an image criteria score and a visual grading analysis score...

	Case Report: Subcutaneous echinococcosis of the knee - The Lancet
	A 34-year-old woman was referred to our department with a slow-growing mass in the right knee during the previous 7 months. She lived in a small farming village in the Spanish countryside, and kept a dog as a pet. She had no medical history of note and was on no medication. She was feeling well and had not lost any weight. On examination, she was afebrile and had a painless grapefruit-sized mass in the superiomedial aspect of the right knee...

	Investigation of the effect of GaAs laser therapy on cervical myofascial pain syndrome - Rheumatology International
	In conclusion, the results of our study have not shown the superiority of GaAs laser therapy over placebo in the treatment of cervical myofascial pain syndrome, but we suggest that further studies on this topic be done using different laser types and dosages in larger patient populations...
	A Prognostic Model for the Presence of Neurogenic Lesions in Atypical Idiopathic Scoliosis - Spine
	The model derived in this study indicates that the probability of neurogenic lesions is extremely low in most patients with idiopathic scoliosis with atypical features. However, patients with severe curves despite skeletal immaturity and an abnormal neurologic examination have a significant probability of neurogenic lesions. Therefore, clinical efficiency will be enhanced by narrowing the indications for MRI to those patients with these risk factors...
	Fat Suppression Magnetic Resonance Imaging in Shoulders of Patients with Polymyalgia Rheumatica - Journal of Rheumatology
	The absence of extracapsular abnormalities in the early shoulder disease of PMR does not confirm the hypothesis of a capsular-based disorder...
