Cervical lymph node metastases may be the initial manifestation of occult cancer. Despite a very exhaustive search, the primary site of approximately 2-10% of these tumours remain undetected. Evaluation of the patient includes: detailed physical examination of skin, upper airways (fiberoptic endoscopy), salivary glands and thyroid; fine-needle biopsy, multiple endoscopic biopsies, and imaging s...

The radiographic image is the bidimensional projection of a tridimensional volume. Interpretation of such an image is sometimes uneasy as we cannot determine ot which level the shadows are located. To dissociate the superimposed shadows, the radiologist may rely on different techniques including fluoroscopy, profile view, radiosteoroscopy, conventional tomography, transverse axial tomography or...

This review is a sequel to our 8 previous reports summarizing the most important published research for singlephoton emission computed tomography (SPECT), cardiac positron emission tomography (PET), cardiac computed tomography (CT), and cardiac magnetic resonance imaging (MRI). This report generally covers the English-language published data between July 1, 2011, and September 30, 2012. We have...

A review of state-of-the-art maxillofacial imaging is presented. Current imaging techniques include intra-oral radiographs, dental panoramic tomography, multidetector helical computed tomography, cone-beam computed tomography (CBCT) and magnetic resonance imaging (MRI). The commonest conditions encountered in clinical radiological practice are reviewed, including maxillofacial deformities, comp...

Squamous cell carcinoma (SCC) of the kidney is a rare entity. Coexistence of SCC with xanthogranulomatous pyelonephrits is exceedingly rare with only few reports in the literature. We report a case of a 45-year-old male patient with xanthogranulomatous pyelonephritis coexistence with renal SCC in one kidney, which proved radiologically and histopathologically. The patient presented to the medic...

Microvascular abnormalities of the coronary circulation are present in several cardiac disorders, are associated with risk factors, and may be present in systemic disease. For the diagnosis and quantification of microvascular dysfunction, non invasive imaging techniques can be used. This paper will highlight the roles of exercise ECG, single photon emission computed tomography, echocardiography...

In our study, in a 52-year-old man, specific and nonspecific findings of Schistosoma infestation were examined using ultrasonography, computed tomography, and magnetic resonance imaging. On computed tomography, capsular and septal calcifications and contrast enhancement of the liver capsule were seen. On T1-weighted magnetic resonance images diffuse hypointensity was seen in periportal spaces; ...

Unidentified heart valve disease is associated with a significant morbidity and mortality. It has therefore become important to accurately identify, assess and monitor patients with this condition in order that appropriate and timely intervention can occur. Although echocardiography has emerged as the predominant imaging modality for this purpose, recent advances in cardiac magnetic resonance a...

We describe the magnetic resonance imaging (MRI) findings of 13 cm-sized low-grade angiosarcoma of the breast that occurred in a 23-year-old woman. Magnetic resonance examination revealed an ill-defined mass with marked high-signal intensity on T2-weighted images and persistent heterogeneous enhancement. Thirty months later she developed bone metastases, incidentally found on an MRI performed t...

Background Obstructive uropathy is a common public health issue that requires imaging research for providing necessary information. The data is important for determining treatment options, and may influence selective management choices. Objective The aim of the study is to determine whether magnetic resonance urography or computerized tomography urography is the best imaging modality among pa...
