Non-invasive MRI assessment of the articular cartilage in clinical studies and experimental settings. World J Radiol 2010; 2(1): 44-54 http://www.wjgnet.com/1949-8470/full/v2/i1/44.htm World Journal of Radiology (World J Radiol, WJR, online ISSN 1949-8470, DOI: 10.4329) is a monthly peer-reviewed, online, open-access, journal supported by an editorial board consisting of 304 experts in radiology from 38 countries. The major task of WJR is to rapidly report the most recent improvement in the research of medical imaging and radiation therapy by the radiologists. WJR accepts papers on the following aspects related to radiology: Abdominal radiology, women health radiology, cardiovascular radiology, chest radiology, genitourinary radiology, neuroradiology, head and neck radiology, interventional radiology, musculoskeletal radiology, molecular imaging, pediatric radiology, experimental radiology, radiological technology, nuclear medicine, PACS and radiology informatics, and ultrasound. We also encourage papers that cover all other areas of radiology as well as basic research.

Over the past decade, there have been and continues to be many significant technical advancements in cardiac MR and multi-detector computed tomography (MDCT) technologies. The strength of MR imaging relies on a variety of pulse sequences and the ability to noninvasively provide information on myocardial structure, function and perfusion in a single imaging session. The recent technical developments may also allow CT technologies to rise to the forefront for evaluating clinical ischemic heart disease. Components of reperfusion injury including myocardial edema, hemorrhage, calcium deposition and microvascular obstruction (MO) have been demonstrated using MR and CT technologies. MR imaging can be used serially and noninvasively in assessing acute and chronic consequences of reperfusion injury because there is no radiation exposure or administration of radioactive materials. MDCT is better suited for assessing coronary artery stenosis and as an alternative technique for as- WJR|www.wjgnet.com World Journal of Radiology EDITORIAL sessing viability in patients where MR imaging is contraindicated. Changes in left ventricular (LV) volumes and function measured on cine MR are directly related to infarct size measured on delayed contrast enhanced images. Recent MR studies found that transmural infarct, MO and peri-infarct zone are excellent predictors of poor post-infarct recovery and mortality. Recent MR studies provided ample evidence that growth factor genes and stem cells delivered locally have beneficial effects on myocardial viability, perfusion and function. The significance of deposited calcium in acute infarct detected on MDCT requires further studies. Cardiac MR and MDCT imaging have the potential for assessing reperfusion injury components and manifestations. © 2010 Baishideng. All rights reserved.
