The involvement of the appendix by lymphomas, both primarily or secondarily, is extremely rare; primary lymphomas account for less than 0.02% gastrointestinal neoplasm. We present rare case a patient who debuts with low bleeding as main symptom. Colonoscopy found an extra mucosal tumour on posterior aspect ceccum and from appendicular orifice. Primary confirmed multislice computed tomography la...
INTRODUCTION AND OBJECTIVES Multislice computed tomography is an excellent technique for the detection of significant coronary artery lesions. Our purpose was to assess whether computed tomography could replace routine invasive coronariography before valvular surgery. METHODS We studied 106 consecutive patients (mean age: 67 [10]): 76% aortic valvular disease (62% stenosis, 14% regurgitation)...
After aneurysmal subarachnoid hemorrhage, most center practices treatment modality selection based on size and geometry in computed tomographic angiography. However, the validity as compared to digital subtraction angiography (DSA) is not well studied. Twenty patients with ruptured internal carotid artery aneurysm were identified in a two-year period. Mean difference in measurements from 3D com...
background and aims. cone-beam computed tomography (cbct) is an imaging system which has many advantages over computed tomography (ct). in ct scan, hounsfield unit (hu) is proportional to the degree of x-ray attenuation by the tissue. in cbct, the degree of x-ray attenuation is shown by gray scale (voxel value). the aim of the present study was to investigate the relationship between gray scale...
