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...

background: early diagnosis of brain tumors has significant effect on the treatment process. brain metastatic tumors are usually diagnosed following the neurological symptoms in patients or incidentally after computerized tomography (ct) scan and magnetic resonance imaging (mri) requests of the brain. objectives: implementation of a new method for being informed about the origin of brain tumors...

organic academia are diverse group of disorders characterized by abnormal degredation of specific amino acid in the specific catabolism due to an enzymeactivity defect which mainly due to enzyme deficiency. the majority of the classic organic acid disorders are caused by abnormal catabolism of branched-chain amino acids like lysine. maple syrup urine disease (msud), propionic acidemia, methylma...

calcifying aponeurotic fibroma (caf) is a rare, benign fibroblastic tumor that typically occurs in the palms of the hands and soles of the feet, in children and adolescents. due to its infiltrative nature, this tumor can mimic malignancy on preoperative magnetic resonance imaging (mri) and has a predilection for local recurrence. there are very few reports in the literature that describe featur...
