conclusions thi visualizes appendix better than conventional us. it is a simple and time saving method that may eliminate further diagnostic imaging, and it may decrease negative appendectomy rates and related complications. patients and methods the study was performed on 185 patients who applied for routine us examinations in whom clinical findings of appendicitis were detected in 25. we searc...

UNLABELLED In PET, transmission scanning for attenuation correction has most commonly been performed with an external positron-emitting radionuclide source, such as (68)Ge. More recently, combined PET/CT scanners have been developed in which the CT data can be used for both anatometabolic image formation and attenuation correction of the PET data. The purpose of this study was to assess the qua...

background: ultrasonography is an imaging method which, due to its relative economy, is becoming more widely available in regions of the world where fasciola hepatica infection occurs most frequently. in this report, we describe the sonographic findings of hepatic lesions in patients with fascioliasis to help confirmation of the sonographic characteristics of this disease and thus aid in its di...

background the most common soft tissue tumors during infancy and childhood are vascular lesions. although the vast majority of these lesions have typical clinical features with no need for any further exam, but sometimes atypical superficial or deeply located lesions require complementary studies to be diagnosed and classified. in that way it is also very important to exclude very less common m...

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...

testicular scintigraphy has been well validated in the evaluation of patients with suspected testicular torsion and provides an accurate evaluation of testicular perfusion at the lime of imaging. however, the presence of normal or increased perfusion to the testis does not definitively exclude the necessity for surgical intervention. a case of intermittent testicular torsion, with a review of t...

inflammatory myofibroblastic tumor (imt) in the spine or paraspinal area is extremely rare. here, we report a rare case of a 56-year-old man who had pathological-proven spinal epidural imt showing a malignancy-like infiltrative feature on mr imaging with alteration of t2 signal intensity on follow-up from slightly high to low compared with initial mr imaging. to the best of our knowledge, this ...

infertility can be defined as the inability to conceive a pregnancy after 1 year of unprotected intercourse or after 6 months in a woman over 35 years old. the use of sonography, in particular transvaginal sonography (tvs), has become an integral component of the evaluation and treatment of infertility. the tvs allows high-resolution assessment of the uterus, ovaries, and fallopian tubes. tvs p...

Molecular imaging is the noninvasive visualization of normal as well as abnormal cellular processes at a molecular or genetic level of function. It is used to provide characterization and measurement of biological processes in living animals and humans (in vivo). The discipline of molecular imaging evolved rapidly over the past decade through the integration of cell biology, molecular biology a...
