To investigate the role of Computer Tomography (CT) in the esophageal cancer surgery. 97 cases confirmed by pathology as esophageal cancer were retrospectively analyzed with preoperative Computer Tomography images and intraoperative situation. Tthe Computer Tomography can accurately display the thickness and length of the lesion segment esophageal wall, the relations between tumor and the aorta...

conclusions performing the routine chest ct in high-energy blunt trauma patients (with a mean injury severity of 9), although leading to the diagnosis of some occult injuries, has no impact on the outcome and does not decrease the in-hospital stay and icu admission time. it seems that performing the routine chest ct in these patients may lead to overtreatment of nonsignificant injuries. the dec...

bronchial leiomyoma is extremely rare. to date less than 60 cases have been reported in the world literature. the presented case here is a 30 year old woman who had been treated for bronchial asthma for several years. her chest radiograph showed bulluos emphysematous changes in the right lung and computer tomography scan found the tumor in the right main bronchus near carina. diagnosis was made...

  Background: The purpose of this study was to determine whether Multi-Detector Computed Tomography (MDCT) in addition to plain radiographs influences radiologists’ and orthopedic surgeons’ diagnosis and treatment plans for delayed unions and non-unions.   Methods: A retrospective database of 32 non-unions was reviewed by 20 observers. On a scale of 1 to 5, observers rated on X-Ray and a...

by producing undistorted three-dimensional images of the area under examination, cone-beam computed tomography (cbct) systems have met many of the limitations of conventional radiography. these systems produce images with small field of view at low radiation doses with adequate spatial resolution that are suitable for many applications in endodontics from diagnosis to treatment and follow-up. t...

INTRODUCTION To the best of our knowledge, this is the first case report of successful treatment for bipolar II disorder using a combined ketamine and transcranial magnetic stimulation treatment. CASE PRESENTATION A 43-year-old Caucasian unemployed man presented to us with treatment-resistant bipolar II disorder, currently in a mixed state.

We describe the evaluation of the registration of Positron Emission Tomography (PET) scans with X-ray Computed Tomography (CT) scans of the human brain. A CT scan and a PET scan of the same person were obtained with fiducial markers placed on the person's head. The CT scan and the PET scan were then registered, first by using the fiducial markers, and next by applying the registration method cu...
