trauma is the most common reason in 1-34 years olds. in patient with multiple traumas, the head is the most common involved part. the importance of computed tomography (ct scan) in diagnosis of brain trauma is well established and ct of the brain is a choice method. finding lesion in brain traumatic patient is very important so goal of this study is finding of brain ct scan in traumatic patient...

conclusions pet/ct can provide diagnosis and more accurate staging, location of tumor with its capability in providing the anatomical and physiological information synchronizes. therefore pet/ct plays an important role in oncology. objectives in this paper, we evaluate application of pet/ct for improve oncologic imaging. methods the papers were searched in pubmed and scopus databases with the r...

for obtaining reservoir petrophysical properties, for example porosity, non-destructive methods such as x-ray computed tomography, ct, seems to be precise and accurate. porosity is deducted from the ct image with a single scan via different techniques, such as pore space detection by image segmentation techniques then correlation with porosity. more than one hundred samples with carbonate li...

objective(s): expression of her2 in gastric carcinoma has direct prognostic and therapeutic implications in patient management. the aim of this study is to determine whether a relationship exists between standardized uptake value (suv) and expression of her2 in advanced gastric carcinoma. methods: we analyzed the 18f-fdg pet/ct results of 109 patients that underwent gastrectomy for advanced gas...

in this study, aggregation behavior of a water soluble cationic metalloporphyrin, meso-tetrakis (2,3,5,6-tetrafluoro-n,n´,n´´-trimethyl ammonium phenyl) porphyrin nickel(ii) [ni(ii)(tf4tmapp)]4+ is investigated in 5 mm aqueous phosphate buffer of ph 7.0 at 25.0 °c and various ionic strengths using optical absorption and resonance light scattering spectroscopic methods. the results suggest that ...

conclusions ct epidurography is not closely correlated with a clinical assessment of epidural block; thus, a clinical assessment of the sensory block is mandatory. the use of opioid analgesia in combination with local anesthetics may compensate for the lack of efficacy of local anesthetics alone. objectives the primary objective of this study was to evaluate, by ct imaging and digital multiplan...
