results loss of consciousness (gcs drop or amnesia) was markedly associated with abnormal brain ct scan (p < 0.05). interestingly, we found 7 patients with normal clinical examination but significant abnormal brain ct scan. conclusions according to the results of our study, we recommend that all patients with minor head trauma underwent brain ct scan in order not to miss any life-threatening he...

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...

Figures 1 and 2 describe the management of a 47-year old patient presenting with a chronic false aneurysm after an extra-anatomic bypass placed for aortic coarctation during childhood. The condition was treated with two covered stents of decreased diameters and an hourglass-shaped plug. Post-procedure and control imaging at 1 year showed no complications. Figure 1: Preoperative findings. (A) Th...

This study extends the 'zero scan' method for CT imaging of polymer gel dosimeters to include multislice acquisitions. Multislice CT images consisting of 24 slices of 1.2 mm thickness were acquired of an irradiated polymer gel dosimeter and processed with the zero scan technique. The results demonstrate that zero scan-based gel readout can be successfully applied to generate a three-dimensional...

X-ray computed tomography (CT) systems with high resolution (also known as micro-CT systems) have been developed over the last two decades and have been used with great success in small animal studies. A micro-CT scanner is based on the same underlying physical principle as a clinical CT scanner, but it is designed for higher-resolution imaging. It produces three-dimensional (3D) tomographic da...

background since tuberculosis (tb) is a major public health problem that is a leading cause of mortality and morbidity among infectious diseases worldwide, early diagnosis and treatment are important to control an effective tuberculosis (tb) and also the increasing number of patients with atypical manifestations of active tb. it suggests more evaluation for active tb in fibrotic lesion in ct sc...
