A 59-year-old woman visited a local hospital for fever and was diagnosed as having infective endocarditis (IE) on the basis of blood cultures and transthoracic echocardiography. Based on clinical episodes of subarachnoid hemorrhage after admission, it was judged that she was not a good candidate for urgent open heart surgery, and it was decided to treat her with conservative medical therapy for...

Abstract Background and aim Despite improvements in the imaging modalities, optimal protocol for extracranial facial nerve using 1.5 T MRI is still debatable. Pre-operative mapping of could provide valuable information surgeons. The current study aimed to evaluate choose proper protocols segment pre-op imaging. Patients methods Extracranial nerves on tumoral normal side 19 patients (38 nerves) ...

BACKGROUND AND PURPOSE It is generally considered that tissue that appears abnormal on T2 MRI is already infarcted and that any penumbra lies outside the T2-visible lesion. We investigated the distribution of infarcted tissue using proton spectroscopic MRI. METHODS In patients with symptoms of acute hemispheric ischemic stroke, imaged within a maximum of 3 days of stroke, we explored the dist...

PURPOSE Using magnetic resonance imaging (MRI), residual tumor cannot be differentiated from nonspecific postoperative changes in operated patients with brain gliomas. The higher specificity and sensitivity of L-(methyl-11C)-labeled methionine positron emissions tomography (MET-PET) in gliomas has been demonstrated in previous studies and is the rationale for the integration of this investigati...

BACKGROUND Gadophrin-2 is a new MRI contrast agent with high affinity for necrotic myocardium. The aim of the study was to evaluate whether noninvasive measurements of infarct size after thrombolysis are possible with gadophrin-2-enhanced MRI. METHODS AND RESULTS Coronary artery thrombosis was induced in 3 groups of dogs by the copper-coil technique. Thrombolytic therapy together with aspirin...

BACKGROUND In the UK, prostate cancer (PC) is the most common cancer in men. A diagnosis can be confirmed only following a prostate biopsy. Many men find themselves with an elevated prostate-specific antigen (PSA) level and a negative biopsy. The best way to manage these men remains uncertain. OBJECTIVES To assess the diagnostic accuracy of magnetic resonance spectroscopy (MRS) and enhanced m...

STUDY DESIGN This was a single surgeon, single center-based retrospective study with prospective data collection. PURPOSE To assess the correlation between T2-weighted magnetic resonance imaging (MRI) signal intensity (SI) changes and factors such as age, duration of symptoms, baseline modified Japanese Orthopedic Association (mJOA) score and to determine its prognostic value in predicting re...

BACKGROUND Cardiovascular diseases are the most prevalent cause of morbidity and mortality affecting millions of people globally. The most effective way to counter cardiovascular complications is early diagnosis and the safest non-invasive diagnostic approach is magnetic resonance imaging (MRI). In this study, superparamagnetic ferrite nanoparticles doped with zinc, exhibiting highly enhanced s...

PURPOSE Myocardial iron overload remains an important problem and results in cardiac dysfunction in patients with thalassemia major (TM). The ratio of color M-mode flow propagation velocity to early diastolic transmitral flow velocity (E/Vp) in echocardiography is a marker of increased left ventricular filling pressure, which is independent of preload, afterload, and heart rate. We examined the...
