conclusion osem3d may provide better image quality and higher contrast than other methods for small animal imaging with the new myocardial imaging agent, [18f] fptp. results the location and size of myocardial infarction on pet images correlated closely with that observed with ttc staining. among the four reconstruction methods, osem3d provided the best assessment of infarct size (r2 = 0.994, p...

background: to analyze the characteristic performance of magnetic resonance spectroscopy (mrs) and susceptibility weighted imaging (swi) in cerebral alve-olar echinococcosis (cae). methods: we retrospectively analyzed 10 clinical-identified cae cases mr per-formance, and summarized the mrs and swi performance of cae. results: the 10 cases of cae all had the history of primary hae, among who 6 c...

background dynamic contrast-enhanced magnetic resonance imaging (dce - mri) has been widely used in the management of breast cancer, and its diagnostic value in breast imaging has been demonstrated. there have only been a few reports regarding the usefulness of pre-contrast imaging. knowledge about clinically significant findings of preoperative, pre-contrast t1 and t2 mr images will allow more...

background: sickle-cell disease (scd) is an inherited hemoglobin childhood disorder, frequently complicated by pulmonary hypertension and cardiac involvement. cardiovascular events and complications are the leading cause of mortality and morbidity in patients with scd. tissue doppler imaging and the myocardial performance index (tei index), are simple indices for the assessment of the cardiac f...

background: considering suggested formula in the references and pcwp measured by catheterism, in the present study the relation between pulmonary capillary wedge pressure (pcwp) measured the flow velocity of mitral valve and mitral annulus motion through tissue doppler imaging is evaluated methods: 52 cases of severe ms were admitted for balloon mitral valvolotomy (bmv) are included in this stu...

purpose : to report the evaluation of the treatment response in choroidal hemangioma with application of enhanced depth imaging optical coherence tomography (edi-oct) technique case report : a 73-year-old woman with a circumscribed choroidal hemangioma in the posterior pole of her left eye underwent photodynamic therapy and intravitreal injection of bevacizumab. edi-oct obtained from the affect...

introduction: nowadays, science mapping is considered an excellent technique for decision-makers to find solutions for problems in research planning and development. in this work, we aimed to depict a science map of “radiology, nuclear medicine, and medical imaging” in iran. methods: all publications indexed in thomson reuters web of science database in the fields mentioned above with at least ...

dextrocardia is a cardiac positional anomaly in which the heart is located in the right hemithorax with its base-to-apex axis directed to the right and caudad. situs inversus is an autosomal recessive disorder that causes organs in the chest and abdomen to be positioned in a mirror image from their normal position. dextrocardia may occur in isolation or as part of situs inversus. similarly, sit...

background: pre-clinical investigation of stem cells for repairing damaged myocardium predominantly used rodents, however large animals have cardiac circulation closely resembling the human heart. the aim of this study was to evaluate whether spect/ct myocardial perfusion imaging (mpi) could be used for assessing sheep myocardium following an acute myocardial infarction (mi) and response to int...
