Radiographs and magnetic resonance images were not published for want of space. Magnetic resonance imaging is superior to computed tomography for detection of a soft tissue mass. Hence computed tomography was not considered in our preoperative investigations. The diagnosis of osteosarcoma was not made before the biopsy. Open biopsy was performed rather than fine-needle aspiratory cytology or ne...

Gamna-Gandy bodies (siderotic nodules) represent organized foci of hemorrhage in the spleen that is caused by portal hypertension. Gamna-Gandy bodies contain hemosiderin, fibrous tissue, and calcium. Magnetic resonance imaging has been approved as the most sensitive imaging modality for the detection of these nodules due to their iron content. Computerized tomography and ultrasonography also he...

Functional neuroimaging provides a direct way of investigating the pathophysiology of schizophrenia in vivo. The function of neurotransmitters implicated in schizophrenia, such as dopamine and glutamate, can be assessed using molecular imaging techniques such as positron emission tomography (PET), single-photon emission tomography (SPET) and magnetic resonance spectroscopy (MRS). Regional brain...

This pictorial essay is a review of the computerized tomography and magnetic resonance imaging of a few solitary primary osseous lesions encountered in the adults. The lesions discussed include giant cell tumor, Langerhans cell histiocytosis, Paget'sdisease, plasmacytoma, fibrous dysplasia and osteoblastoma. Challenges in computerized tomography and magnetic resonance imaging diagnosis of these...

There are studies supporting the suggestion that a severe psychological stress in the elderly can be the risk factor of Alzheimer's dementia (AB) and other types of dementia. We have reviewed the findings of single photon emission tomography, positron emission tomography, magnetic resonance imaging and functional magnetic resonance imaging (fMRI), related to brain function and structure in AD a...

Alzheimer’s disease (AD) is the most common form of dementia (Bird, 2001), a group of conditions that gradually destroys brain cells and leads to progressive decline in mental function. This irreversible brain disorder is characterized by neuronal loss and the appearance of neuritic plaques containing amyloid-β-peptide and neurofibrillary tangles (Cummings, Pike, Shankle, & Cotman, 1996). Appro...

2013 is a remarkable year in cardiovascular medicine from a historical point of view. It can be considered a crown year for non-invasive clinical cardiovascular imaging as we can look back on 60 years of echocardiography, 40 years of nuclear cardiology, 30 years of cardiovascular magnetic resonance imaging, and 30 years of cardiac computed tomography. In previous Editor’s Comments, 60 years of ...

Extramedullary haematopoiesis is the production of blood elements outside the bone marrow cavity. In our case computed tomography and magnetic resonance imaging revealed the presence of a rare localization of extramedullary haematopoiesis with encasement of the biliary system in a 59 years-old male Caucasian patient, with chronic myelofibrosis and hepatic failure's symptomatology. Computed tomo...

We advance the magnetomotive-optical coherence tomography (MM-OCT) technique for detecting displacements of magnetic nanoparticles embedded in tissue-like phantoms by using apmplitude and phase-resolved methods with spectral-domain optical coherence tomography (SD-OCT). The magnetomotion is triggered by the external, noninvasive application of a magnetic field. We show that both amplitude and p...

PURPOSE To study the imaging exams more commonly used for abdominal aortic aneurysms evaluation - ultrasonography, conventional computerized tomography, helical computerized tomography and nuclear magnetic angioresonance - comparing the preoperative measurements reached by those radiological methods with the measurements made during the surgical procedures. METHODS Patients who had indication...
