introduction: 5-ht1a receptor is related with a variety of neuropsychiatric disorders. . in this study a phenolic analogue derived from dway [desmethyl way-100635 (n-(2-(1-(4-(2-methoxyphenyl)piperazinyl)-ethyl))-n-(2-pyridinyl) cyclohexanecarboxamide)] is used to design the desired structure of 5-ht1a receptor imaging agents after labeling with [99mtc (co) 3(h2o) 3] + core via dithiocarbamate ...

case presentation we report a 5-year-old boy, who was presented with sudden right hand monoparesis and dysarthria. conclusions the patient was investigated with magnetic resonance angiography and diagnosed as md. introduction moyamoya disease (md) is a disorder caused by blocked arteries at the base of the brain. as the normal blood vessels narrow and become blocked, a person may suffer a strok...

background: general practitioners (gps) are usually the first-line doctors visiting patients with breast problems. therefore, their knowledge about breast diseases is of significant importance for proper screening and referral of patients and warrants scrutiny. the purpose of this study was to assess the knowledge of gps regarding different breast imaging modalities. methods: in this cross-sect...

ebstein anomaly is characterized by apical displacement of the septal and posterior tricuspid valve leaflets, leading to atrialization of the right ventricle and could be diagnosed in a routine transthoracic echocardiography exam. we reported a young man with right sided heart failure symptoms who was found to have biventricular failure with suspected apical displacement of septal leaflet of tr...

background: ultrasound propagation velocity was measured experimentally in normal, fibroadenoma and ductal carcinoma breast tissues, in order to distinguish normal breast tissue from tumors. materials and methods: in quantitative measurements of ultrasound velocity, 403 breast tissue images were selected, comprising 130 normal breast tissue, 130 fibroadenoma, and 143 ductal carcinoma tumors. th...

conclusion fs t2 w and ce fs t1 w sequences of axial planes were the most useful sequences in determination of active sacroiliitis. therefore, in patients with renal failure or allergy to contrast media, fs t2 wi can be obtained to detect active sacroiliitis. objectives the aim of this retrospective study was to assess the value of different magnetic resonance imaging (mri) sequences in evaluat...

iniencephaly is a rare kind of neural tube defect that is classified into two types of iniencephaly apertus and iniencephaly clausus. this anomaly could be diagnosed prenatally by obstetric ultrasonography and terminated by therapeutic abortion; however, it could be undiagnosed until birth similar to our case due to the abnormal position of the fetus or lack of experience of the sonographer. du...

conclusion adrenal iron in β-tm can be reliably measured in 3 tesla mri. the results highlight the absence of correlation between adrenal iron deposition both with serum ferritin and hepatic iron. results among patients, there was no significant correlation between plasma ferritin and adrenal t2*. significant difference was detected among t2* values of adrenals between the patient and control g...
