Intracranial epidermoid cysts are generally located in the cerebellopontine and parasellar areas and appear hypo-dense on computed tomography and hypo-intense on T1-weighted magnetic resonance imaging. We report a case of an unusual epidermoid cyst of the cerebellopontine angle extending into the upper cervical canal that appeared hyper-dense on computed tomography scanning, hyper-intense on T1...

BACKGROUND A large variety of imaging techniques is an integral part of modern medicine. Introducing radiological imaging techniques into the dissection course serves as a basis for improved learning of anatomy and multidisciplinary learning in pre-clinical medical education. METHODS Four different imaging techniques (ultrasound, radiography, computed tomography, and magnetic resonance imagin...

Most of the existing research in medical image segmentation has focused on magnetic resonance (MR) and computed tomography (CT). Much less work has been done in the segmentation of X-ray images. Nevertheless, medical specialists often examine X-rays images of spinal columns to determine the presence of abnormalities or dysfunctions and to analyse the vertebral mobility. To help them to establis...

Conventional radiographs used for the management of endodontic problems yield limited information because of the two-dimensional nature of images produced, geometric distortion and anatomical noise. This newer review paper seeks to clarify three-dimensional imaging techniques that have been suggested as adjuncts to conventional radiographs. These include tuned aperture computed tomography, magn...

We have proposed a new imaging modality, magnetoacoustic tomography with magnetic stimulation (MAT-MS) to image the electrical impedance distribution. In this paper we report out pilot experimental study. In MAT-MS, the tissue is put in a static magnetic field and a pulsed ( s μ ) magnetic field. The pulsed magnetic field induces eddy current in the tissue. Consequently, the tissue will emit ul...

ackground Ethiopia is one of the countries that has high burden of all forms of tuberculosis and there is no published report on computerized tomography scan and/or magnetic resonance imaging of intracranial tuberculomas. Objective : to review the clinical, computerized tomography and/or magnetic resonance imaging features of intracranial tuberculoma. Methods retrospective review of patient’s...

BACKGROUND The stroke is leading cause of death and severe disability worldwide. Atherosclerosis is responsible for over 30% of all ischemic strokes. It has been recently discovered that plaque morphology may help predict the clinical behavior of carotid atherosclerosis and determine the risk of stroke. The noninvasive imaging techniques have been developed to evaluate the vascular wall in an a...

In order to localise neuroendocrine tumours of the foregut type (that is, of the stomach, duodenum, and pancreas), 18 patients were studied prospectively by endoscopic ultrasonography, computed tomography, transabdominal ultrasonography, magnetic resonance imaging, and somatostatin receptor scintigraphy. These 18 patients had a total of 25 primary tumour lesions which were verified histological...

Objective: To compare superparamagnetic iron oxide-enhanced magnetic resonance imaging with 5-phase computed tomography in the detection and characterisation of focal liver lesions. Patients and Methods: We prospectively performed 5-phase computed tomography scans followed by magnetic resonance imaging of the liver with superparamagnetic iron oxide magnetic resonance contrast medium in patients...
