PURPOSE To compare the dose and image quality of a standard dose abdominal and pelvic CT with Filtered Back Projection (FBP) to low-dose CT with Adaptive Iterative Dose Reduction 3D (AIDR 3D). MATERIALS AND METHODS We retrospectively examined the images of 21 patients in the portal phase of an abdominal and pelvic CT scan before and after implementation of AIDR 3D iterative reconstruction. Th...

background focused assessment with sonography for trauma (fast) is a precise, non-invasive, and low cost method to assess free abdominal fluid in trauma patients. objective this study assessed the relationship between free intra-abdominal fluid and organ injury in blunt abdominal trauma and designed a scoring system based on fast. patients and methods a total of 200 patients with blunt abdomina...

trauma is the leading cause of death in united states in the younger population. cardiac trauma is common following blunt chest injuries and is associated with high morbidity and mortality. this study discusses various multidetector computed tomography (mdct) findings of cardiac trauma. cardiac injuries are broadly categorized into the most commonly occurring blunt cardiac injury and the less c...

various dimensions of the human vestibular aqueduct were evaluated in two groups, patient and control, and these measurements were compared. both groups were examined clinically, followed by audiometric evaluation and temporal bone high resolution ct scan. it was found that in approximately one third of the patient group (with idiopathic snhl), the vestibular aqueduct was 1.5 mm or larger. also...

background and aims: one of the most common injuries around the world is the traumatic injury of the spine and spinal cord with unknown worldwide situation of traumatic spinal cord injury (tsci) affecting on the effectiveness of preventive policy programs. in addition, because of possibility of making paralysis, the potential injury to the spine could be one of the most important traumas and a ...

Routine evaluation of axial MR images of the cervical spine with high-intensity CSF (long TR/TE spin-echo or gradient-echo images) revealed apparent narrowing of the cord's anteroposterior diameter when these images were compared with corresponding postmyelography CT scans. This discrepancy was believed to be due to the truncation artifact at the CSF-cord boundary. To examine the truncation eff...

A 70-year-old man with past history of hemicolectomy due to colon cancer underwent a follow-up abdominal/pelvic CT scan. CT revealed a right adrenal metastasis and then he underwent FDG-PET/CT study to search for other possible tumor recurrence. In PET images, other than right adrenal gland, there was an unexpected intense FDG uptake at right inguinal region and at first, it was considered to b...

abstract   background: tibial torsion is one of the torsion density which rotating in the longitudes axis of the leg. to measure this deformity, different methods such as radiographic or clinical methods were presented and introduced. methods: in this quasi-experimental study, 30 male athletes were selected randomly. their tibial torsion angle was measured using ct scan, lavand, lokomso, foot p...

In this study, an automated segmentation approach is proposed that segments the liver from input CT images of the liver, and cluster the components into different clusters, separating the liver from any detected suspicious region for further analysis and diagnostics. The proposed methodology relies on two stages mainly; firstly, the liver is segmented from the input CT image by separating it fr...
