Diagnosis of cardiac involvement in sarcoidosis is challenging and usually relies on a combination of clinical findings and imaging abnormalities. The case of a 53-yr-old female is described who presented with ventricular tachycardia and suspected angiosarcoma involving the right atrium and superior vena cava. A combination of magnetic resonance imaging and (18)F-2-fluoro-2-deoxyglucose-positro...

Tumours in the oral cavity and oropharynx differ in presentation and prognosis and the detection of spread of tumour from one subsite to another is essential for the T-staging. This article reviews the anatomy and describes the pattern of spread of different cancers arising in the oral cavity and oropharynx; the imaging findings on computerized tomography and magnetic resonance imaging are also...

magnetic resonance imaging (mri) uses a constant magnetic field and radio waves, a non-invasive method for examining tissues, organs and the skeletal system. the advantages and disadvantages of mri is not fully understood. in the computerized tumor (ct) scan, as an invasive method, the x-rays of the body is used for tomography; which different x-ray attenuation coefficient in tissues as well as...

Noise is an inherent property of medical imaging, and it generally tends to reduce the image resolution and contrast, thereby reducing the diagnostic value of this imaging modality, there is an emergent attentiveness in using multi-resolution Wavelet filters in a variety of medical imaging applications. We Have review recent wavelet based denoising techniques for medical ultrasound, magnetic re...

X-ray tomography is a well-established technique to characterize 3D structures in material sciences and biology; its magnetic analogue--magnetic X-ray tomography--is yet to be developed. Here we demonstrate the visualization and reconstruction of magnetic domain structures in a 3D curved magnetic thin films with tubular shape by means of full-field soft X-ray microscopies. The 3D arrangement of...

Mapping the positions of single electron spins is a highly desired capability for applications such as nanoscale magnetic resonance imaging and quantum network characterization. Here, we demonstrate method based on rotating an external field to identify precise location in vicinity spin sensor. We use nitrogen-vacancy center diamond sensor modulate dipolar coupling proximate crystal by varying ...
