Introduction: Accurate evaluation of femoral and tibial torsion is essential for children or adult with legs deformity, becuse incorrect legs morphogenesis can lead to pathological situation. CT scan is commonly used for the measurement of skeletal bone parameters. But, disability in imaging from standing and sitting posture and absorb dose of patients are deficits of this meth...

This case report of the infantile form of Krabbe disease in a 2 1/2-month-old boy illustrates the complementary findings that may be seen on CT and MR scans. The key finding on the CT scan was increased density in a bilateral symmetrical distribution involving the thalami with extension into the centrum semiovale. The MR scan, on the other hand, more clearly showed demyelination in the brain st...

Background: The accuracy of reduction of ankle fractures using postoperative plain radiographies (x-ray) remainswidely controversial. Some authors have demonstrated that postoperative computed tomography (CT) scan can beuseful for these patients. In current study, the efficacy of x-rays after fixation of ankle fractures was investigated basedon the CT scan findings.Metho...

conceptually traumatic brain injury (tbi) can be classified from a mechanistic perspective as: 1) closed, 2) penetrating, 3) blast, and 4) crush injuries. thus, tbi is a heterogeneous disease and each type of brain injury has different characteristic features often necessitating different approaches to management. the first edition of the guidelines for management and prognosis of penetrating b...

abstract background: high resolution ct scan has made early diagnosis of intraventricular hemorrhage (ivh) easier. posttraumatic intraventricular hemorrhage has been reported to a greater extent because of the ct scan. methods: 904 patients were admitted in the nsicu from march 2001 to march 2002 with severe closed head injury, of those only 31 patients with intraventricular hemorrhage (gcs les...

Introduction: Radiation therapy planning (RTP) is one of the clinical applications in which both CT scan and MRI are used. MR and CT images are applied to determine the target volume and calculation of dose distribution, respectively. In addition, using two imaging modalities increases the department workload and cost. In this study, an algorithm was presented to create synthet...

Results of initial clinical trials of brain tumor chemotherapy after osmotic blood-brain barrier disruption are promising. In general, the procedure is well tolerated. The major complication has been seizures. In this report, data are presented which indicate that the etiology of these seizures is related to the use of contrast agent (meglumine iothalamate) to monitor barrier modification. A se...

background: this study set out to evaluate the utility of cerebrovascular virtual non-contrast (vnc) scans. materials and methods: conventional non-contrast (cnc) and dual-energy computed tomography angiography (de-cta) head scans were conducted on 100 subjects, of which 46 were normal, 15 had parenchymal hematomas of the brain, 13 had ischemic infarction, 22 had tumors, and 4 had calcified les...
