the application of magnetic resonance to diagnostic medical imaging stands as one of the great scientific achievements in the past 50 years. magnetic resonance techniques are easily applied to organs which remain stationary during the imaging procedure, such as the brain and musculoskeletal system. imaging of moving heart structures and circulating blood is considerably more difficult.   clinic...

Introduction: A varicocele is the abnormal dilation and tortuosity of venous plexus above the testicles. The pattern of abnormal heat distribution in the scrotum can be detected through thermal imaging, which is a distant, non-contact, and non-invasive method. The aim of the present study is to detect and grade varicocele. Materials and Methods: This study was conducted on 50 patients with high...

background: finding the safe location of spinal cord for cerebrospinal fluid (csf) during surgical procedures is very important due to its various nature for each patient as well as its potential peripheral nervous system hazards. the aim of this study was to find the relationship between the location of conus medullaris (cm) and gender, age and body mass index (bmi) in order to minimize the po...

introduction: application of chest radiography for all multiple trauma patients is associated with a significant increase in total costs, exposure to radiation, and overcrowding of the emergency department. ultrasound has been introduced as an alternative diagnostic tool in this regard. the aim of the present study is to compare the diagnostic accuracy of chest ultrasonography and radiography i...

background: the recent developments in tissue doppler imaging (tdi) now more than ever permit the quantification of the myocardial function. in the current systems, tissue tracking or displacement curves are generated from color tissue doppler data through the instantaneous temporal integral of velocity-time curves. methods: the purpose of the present study was to assess regional myocardial dis...

Bimodal imaging combines two imaging modalities in order to benefit from their advantages and compensate the limitations of each modality. This technique could accurately detect diseases for diagnostic purposes. Nanoparticles simultaneously offer diagnostic data via various imaging modalities owing to their unique properties. Moreover, bimodal nanoprobes could be incorporated into theranostic s...

Introduction: Recently the most accurate diagnostic method in the diagnosis of prosthesis infection is the combination of Tc-99m labeled leukocyte/bone marrow imaging. However the diagnostic efficiency of the test is influenced because of its low spatial resolution. Recently SPECT/CT imaging is implicated in this test with efficient additional diagnostic improvement. In the dep...

introduction: external root resorption (err) is associated with physiological and pathological dissolution of mineralized tissues by clastic cells and radiography is one of the most important methods in its diagnosis. the aim of this experimental study was to evaluate the accuracy of conventional intraoral radiography (cr) in comparison with digital radiographic techniques, i.e. charge-coupled ...

introduction: using pan or selective computed tomography (ct) scan in management of multiple trauma patient is a matter of debate. therefore, the present study was designed aiming to compare the findings of pan and selective ct scans in management of multiple trauma patients. method: this is a prospective cross-sectional study, on patients presented to the emergency department (ed) of shohadaye...
