Abstract:

AbstractFor years, magnetic resonance angiography (MRA) has been a leading imaging modality in the assessment of venous disease involving the pelvis and lower extremities. Current advancement in noncontrast MRA techniques enables imaging of a larger subset of patients previously excluded due to allergy or renal insufficiency, allowing for preintervention assessment and planning. In this article, the current status of MR venography, with a focus on current advancements, will be presented. Protocols and parameters for MR venographic imaging of the pelvis and lower extremities, including contrast

Abstract:

Background Cerebral venous thrombosis (CVT) is easily missed or misdiagnosed in clinical settings because of its high variability in terms of symptoms and radiological findings. Herein, we aimed to explore a promising modality for confirming presumed CVT in the hope to uncover its superior diagnostic performance to conventional imaging modalities. Case presentation: The patient complained of intolerable pain in her forehead and left eye. Her lumbar puncture opening pressure was 140 mmH2O, and her cerebrospinal fluid composition was normal. No marked abnormalities were observed in routine brain

Abstract:

Central nervous system (CNS) lymphoma must be considered in the differential diagnosis of any immunocompromised patient with a solid brain lesion. In such patients, diagnosis can be made via a careful review of important signs, symptoms, and classic radiologic findings. While there is no single physical exam finding classic for lymphoma, the clinician must carefully evaluate patients for the presence or absence of findings that may suggest an alternative diagnosis. Such findings include the stigmata of endocarditis, symptoms suggestive of pneumonia, or additional non-CNS mass lesions. Addition

Abstract:

MRI is a non-invasive imaging technique that permits the most comprehensive study of aortic diseases. It offers morphological, functional and biochemical information. Conventional ECG-gated spin-echo imaging, cine gradient-echo and contrast-enhanced 3D MR angiography have earned MRI the reputation of being the ideal tool for evaluating the aorta. The phase-contrast imaging technique enables the assessment of flow in the great vessels. MRI can be used to define the location and extent of aneurysms, dissections and aortic wall ulceration. This is the best technique to demonstrate areas of wall thickening related to aortitis or intramural haematoma. MRI may also be used as a tool to study aortic physiology by assessment of elastic aortic properties, stiffness and aortic wall shear stress. MRI is particularly useful in patients with either contraindications to iodinated contrast material or in those with known aneurysms who require sequential follow-up.

Abstract:

The peculiar features of gadolinium-chelated contrast agents and the development of contrast-enhanced inversion recovery technique in the late 1990s formed the basis of early and late gadolinium enhancement imaging, revolutionizing the application of magnetic resonance imaging in patients with cardiac diseases. Several clinical studies have indeed demonstrated the clinical benefits of early and late gadolinium enhancement imaging, including the discrimination between scarred/fibrotic myocardium and normal myocardium and the identification of mural thrombi and areas of microvascular obstruction among patients with acute myocardial infarction. The technique currently plays a key role in the differential diagnosis between cardiac diseases with ischaemic and non-ischaemic aetiology and in the assessment of patients with acute myocardial infarction and its complications. Due to its invaluable ability to provide diagnostic and prognostic information, it is indeed more frequently implemented for patients’ clinical management and decision-making. This chapter discusses the technical aspects of early and late gadolinium enhancement imaging, reviews the initial studies that led to the validation of the technique, and focuses on its application according to the main clinical syndromes (i.e. acute and chronic myocardial infarction, heart failure, conduction diseases, and ventricular arrhythmias). Guidelines for correct image acquisition and interpretation will be also provided, in particular, how to deal with patients with cardiac arrhythmias or with patients unable to breath-hold properly, and how to discriminate true late gadolinium enhancement areas from artefacts is discussed.

Abstract:

Hepatocellular carcinoma arises commonly on the background of liver cirrhosis. Patients presenting with clinical symptoms have advanced stage and often are unsuitable for curative therapies. Diagnosis of hepatocellular carcinoma is commonly performed by multiphase computed tomography (CT) and / or magnetic resonance imag¬ing scans (MRI). Contrast enhanced ultrasound and MRI with hepatobiliary contrast agents are better in characterizing small lesions. Tumor markers play an adjunct role in diagnosis. For HCC in cirrhotic liver biopsy is seldom required and diagnosis is based on typical imaging features of non-rim arterial phase hyperenhancement and washout on delayed phase and pseudocapsule appearance. This is due to differential blood supply of liver parenchyma, regenerative nodules and tumor. Biopsy is only required in noncirrhotic liver, vascular liver diseases, atypical imaging features. Surveillance programs involving high risk groups can help in early detection of lesions which are amenable for curative therapies. Biannual ultrasound with or without alfa fetoprotein are commonly used surveillance tests. Multidisciplinary teams provide platform for care coordination, reassessments of clinical course, and fine changes in treatment plans required for management of this complex group of patients.

Dispersive material properties provide valuable metrics for characterizing the nature of soft tissue lesions. Magnetic Resonance Elastography (MRE) targets non-invasive breast cancer diagnosis and is capable of imaging the damping properties of soft tissue. 3D time-harmonic displacement data obtained via MRI is used to drive a reconstruction algorithm capable of deducing the distribution of mechanical properties in the tissue. To make the most of this diagnostic capability, characterization of the damping behavior of tissue is made more sophisticated by the use of a Rayleigh damping model. To

Recent publications have highlighted a "non-Archie" behavior in carbonates with complex pore structures. Several theoretical models were introduced, but new practical applications were not derived to solve this issue. Built upon previous theoretical research in a holisti
