Background: To retrospectively evaluate whether quantitative information derived from spectral imaging can improve the differential diagnosis of pancreatic cystic masses including pancreatic solid pseudopapillary epithelial neoplasms (SPENs), mucin- producing cysts and pseudocysts. Materials and Methods: From June 2015 to October 2017, 56 patients (22 pseudocysts, 18 mucin-producing cysts and 1...
conclusion for the identification of nasal bone fractures, ct was significantly superior to conventional radiography. although a staff radiologist showed better values in the identification of nasal bone fracture and differentiation between depressed and non-depressed fractures than a trainee, there was no statistically significant difference in the interpretation of conventional radiography an...
introduction: poor sensitivity and poor signal to noise ratio because of low injected thallium dose and presence of scattered photons are the main problems in using thallium in scintigraphic imaging of the heart. scattered photons are the main cause of degrading the contrast and resolution in spect imaging that result in error in quantification. thallium decay is very complicated and photons ar...
radical resection of a pathological lesion along with the preservation of eloquent cerebral tissue is the principle goal of neurosurgery. brain lesions are usually diagnosed by conventional magnetic resonance imaging (mri), but this method is unable to describe the relationship between lesions and neighboring specific white matter (wm) tracts. diffusion tensor tractograghy (dtt) is a new sophis...
