Magnetic resonance imaging (MRI) is one of the most important clinic diagnostic tool used to obtain high-quality body images. The administration of low-molecular-weight Gd complex-based MRI contrast agents (CAs) permits to increase the 1 H relaxation rate of nearby water molecules, thus modulating signal intensity and contrast enhancement. Even if highly accurate, MRI modality suffers from its low sensitivity. Moreover, low-molecular-weight CAs rapidly equilibrate between the intravascular and extravascular spaces after their administration...

BACKGROUND: MRI-detected subclinical joint inflammation in the hand joints of patients with undifferentiated arthritis (UA) predicts progression to rheumatoid arthritis (RA). It is unknown if adding MRI of the foot increases predictive accuracy compared to the hand alone. METHODS: 1.5-T contrast-enhanced MRI of the unilateral foot (MTP-1-5) and hand (MCP-2-5 and wrist) was performed in 123 patients presenting with UA (not fulfilling the 2010 RA criteria) and scored for bone marrow edema (BME), synovitis and tenosynovitis...

OBJECTIVE: Ultrasound (US) and magnetic resonance imaging (MRI) are recommended in the diagnostic process of rheumatoid arthritis. Research on its comparability in early disease phases is scarce. Therefore, we compared synovitis and tenosynovitis detected by US and MRI on joint/tendon level. METHODS: Eight hundred forty joints and 700 tendons of 70 consecutive patients, presenting with inflammatory arthritis or clinically suspect arthralgia, underwent US and MRI of MCP (2-5), wrist and MTP (1-5) joints at the same day...

White matter damage persists in hypoxic-ischemic newborns even when treated with hypothermia. We have previously shown that intra-ventricular delivery of human glial progenitors (GPs) at the neonatal stage is capable of replacing abnormal host glia and rescuing the lifespan of dysmyelinated mice. However, such transplantation in the human brain poses significant challenges as related to high-volume ventricles and long cell migration distances. These challenges can only be studied in large animal model systems...

PURPOSE: Dynamic contrast enhanced MRI of the heart typically acquires 2-4 short-axis (SA) slices to detect and characterize coronary artery disease. This acquisition scheme is limited by incomplete coverage of the left ventricle. We studied the feasibility of using radial simultaneous multi-slice (SMS) technique to achieve SA, 2-chamber and/or 4-chamber long-axis (2CH LA and/or 4CH LA) coverage with and without electrocardiography (ECG) gating using a motion-robust reconstruction framework...

Application of three-dimensional (3D) printing facilities in orthopaedic surgery is getting popular in resourceconstrained countries. It is cost- and resource-efficient to assist in planning and increasing orthopaedic procedures efficienc y. Furthermore, it improves educational training and provides cheaper prosthesis and creation of customised implants for special cases. Moreover, 3D models of computed tomography (CT) and magnetic resonance imaging (MRI) data play a helpful rule for a more hands-on approach for the surgeon...

BACKGROUND/OBJECTIVES: Data estimating the prevalence of significant findings during the investigation of patients with Chronic Asymptomatic Pancreatic Hyperenzymemia (CAPH) are scanty and heterogeneous, and the diagnostic approach is therefore uncertain. The aim of this study was to meta-analyze pancreatic abnormalities detected at second-level imaging in patients with CAPH. METHODS: Pubmed database was searched until September 2018 for articles evaluating CAPH patients through MRI-Cholangio-Pancreatography with/without secretin (MRCP or s-MRCP) or Endoscopic Ultrasound (EUS)...

BACKGROUND: Objective preoperative assessment of pectus excavatum (PE) deformity in patients is limited to preoperative measurement of severity using computed tomography (CT) or magnetic resonance imaging (MRI). Postoperative assessment is currently subjective as postoperative CT scans are not recommended in light of radiation exposure and high cost to families. White Light Scanning (WLS) is a novel 3D imaging modality that offers an alternative that is a quick, nonionizing, inexpensive, and safe strategy for measurement both pre- and postsurgery...

Background  Scapholunate instability (SLI) is the most common form of carpal instability. Early detection of SLI is imperative as early reconstructive procedures can potentially prevent the natural history of progressive degenerative arthritis. After wrist arthroscopy, magnetic resonance imaging (MRI) remains the next best noninvasive diagnostic option; however, access still remains costly and is often limited in many health care systems worldwide. In this article, we describe a novel device that allows for dynamic X-rays to be taken, accentuating the scapholunate (SL) widening...

Many cardiovascular diseases lead to local increases in relative pressure, reflecting the higher costs of driving blood flow. The utility of this biomarker for stratifying the severity of disease has thus driven the development of methods to measure these relative pressures. While intravascular catheterisation remains the most direct measure, its invasiveness limits clinical application in many instances. Non-invasive Doppler ultrasound estimates have partially addressed this gap; however only provide relative pressure estimates for a range of constricted cardiovascular conditions...

Kinetic parameter values, such as myocardial perfusion, can be quantified from dynamic contrast enhanced (DCE-) magnetic resonance imaging (MRI) data using tracer-kinetic modelling. However, respiratory motion affects the accuracy of this process. Motion compensation of the image series is difficult due to the rapid local signal enhancement caused by the passing of the gadolinium-based contrast agent. This contrast enhancement invalidates the assumptions of the (global) cost functions traditionally used in intensity-based registrations...

Neuromuscular diseases are characterized by progressive muscle degeneration and muscle weakness resulting in functional disabilities. While each of these diseases is individually rare, they are common as a group, and a large majority lacks effective treatment with fully market approved drugs. Magnetic resonance imaging and spectroscopy techniques (MRI and MRS) are showing increasing promise as an outcome measure in clinical trials for these diseases. In 2013, the European Union funded the COST (co-operation in science and technology) action BM1304 called MYO-MRI (www...

EDITORIAL
Timothy S Crall
Recent literature tells us that knee arthroscopy in the setting of osteoarthritis is no better than placebo, but arthroscopy for isolated, nondegenerative meniscus tears is both helpful to patients and cost-effective. Since most patients with osteoarthritis have meniscus pathology, we need an accurate way to rule out degenerative disease in patients who are otherwise good candidates for arthroscopic partial meniscectomy. Magnetic resonance imaging can be misleading. Needle arthroscopy is a new tool that can potentially help dig us out of this diagnostic dilemma...
