May 26, 2004   Quantitative proton magnetic resonance spectroscopy of the cervical spinal cord - Magnetic Resonance in Medicine Proton MR spectroscopy (1H-MRS) provides indices of neuronal damage in the central nervous system (CNS); however, it has not been extensively applied in the spinal cord. This work describes an optimized proton spectroscopy protocol for examination of the human cervical spinal cord. B0 field mapping of the cord revealed periodic inhomogeneities due to susceptibility differences with surrounding tissue...

May 25, 2004   T2 of articular cartilage in the presence of Gd-DTPA2- - Magnetic Resonance in Medicine T2 information and delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) are both used to characterize articular cartilage. They are currently obtained in separate studies because Gd-DTPA2- (which is needed for dGEMRIC) affects the inherent T2 information. In this study, T2 was simulated and then measured at 8.45 T in 20 sections from two human osteochondral samples equilibrated with and without Gd-DTPA2-... May 24, 2004   Human imaging of phosphorus in cortical and trabecular bone in vivo - Magnetic Resonance in Medicine Phosphorus was imaged in vivo in human cortical and trabecular bone and the T1 and T were measured. An ultrashort TE (UTE) pulse sequence (TE = 70 m) was used with half pulse excitation and radial mapping of k-space from the center out. T was measured using multiple echo times and T1 was measured both by saturation recovery and by a method using different RF pulse amplitudes...

May 20, 2004   MRI features of foot and ankle injuries in ballet dancers - British Journal of Radiology Foot and ankle pain is common in ballet dancers. Although clinical examination often points to the underlying cause, imaging is often necessary to confirm the diagnosis and thus ensure appropriate future management. Factors predisposing to the increased incidence of injuries in this population include the classical position in which ballet dancers stand, which is on the tips of the toes in the en pointe position or on the balls of the feet in the demi-pointe position... May 19, 2004   General approach to lytic bone lesions - Applied Radiology When interpreting musculoskeletal radiographs, a radiologist must be able to identify a lytic lesion and provide a definitive diagnosis or a reasonable differential diagnosis for the lesion. This article addresses these issues and details a rational and systematic approach to such lesions...   Grey scale and power Doppler sonographic changes induced by intra-articular steroid injection treatment - Annals of Rheumatic Diseases Conclusion: GSS and PDS appear to be a useful adjunctive tool for assessing short term soft tissue changes induced by intra-articular injection treatment with triamcinolone acetonide in small joints of patients with chronic arthritis... May 18, 2004   Calcific Tendinosis and Periarthritis: Classic Magnetic Resonance Imaging Appearance and Associated Findings - Journal of Computer Assisted Tomography Calcification within tendon and periarticular soft tissues with or without a history of pain is commonly encountered in the interpretation of musculoskeletal MR imaging (MRI) studies. This article presents a pictorial illustration of both the classic and atypical MR imaging (MRI) features of soft tissue calcifications in the musculoskeletal system. Familiarity with this topic can help to avoid pitfalls in imaging diagnosis... May 17, 2004   Magnetic Resonance Imaging in Stress Fractures and Shin Splints - Clinical Orthopedics and Related Research The purpose of the current study was to determine whether stress fractures and shin splints could be discriminated with MRI in the early phase. Twenty-two athletes, who had pain in the middle or distal part of their leg during or after sports activity, were evaluated with radiographs and MRI scans... May 14, 2004   BMD testing hits its stride in community imaging - Diagnostic Imaging As baby boomers hit the prime years for osteoporosis, bone densitometry specialists are seeing a surge in interest. While dual x-ray absorptiometry is well established as the gold standard for detecting bone mineral loss, the questions of who does the detecting and how test results are used remain open... May 13, 2004   The Location of the Biceps Tendon in Completely Displaced Proximal Humerus Fractures in Children: A Report of Four Cases With Magnetic Resonance Imaging and Cadaveric Correlation - Journal of Pediatric Orthopaedics The location of the biceps tendon is a matter of concern for clinicians treating completely displaced proximal humeral fractures in children. This article describes four patients (one 12-year-old boy, two 12-year-old girls, and one 14-year-old girl) who underwent magnetic resonance imaging evaluation of their fractures to discern the location of the biceps tendon. In no case did the tendon become entrapped in the fracture site... May 12, 2004   3D software combines bone, vascular data in angio images - Diagnostic Imaging An algorithm developed by Toshiba for rotational angiography combines blood vessels and bone in a single 3D reconstruction.
