brachial plexus injury (bpi) is an uncommon complication of median sternotomy capable of causing a permanent or transitory sensitivity and/or motor function impairment in the upper limbs. during a cardiac surgery through sternotomy, for the assessment of the thoracic cage configuration and the site of mediastinal structures, a broader surgical field may be required. if the sternal retractors ar...

introduction quantitative susceptibility mapping (qsm) is a new contrast mechanism in magnetic resonance imaging (mri). the images produced by the qsm enable researchers and clinicians to easily localize specific structures of the brain, such as deep brain nuclei. these nuclei are targets in many clinical applications and therefore their easy localization is a must. in this study, we aimed to i...

left ventricular non-compaction cardiomyopathy is a rare congenital cardiomyopathy that affects both children and adults. since the clinical manifestations are not sufficient to establish diagnosis, echocardiography is the diagnostic tool that makes it possible to document ventricular non-compaction and establish prognostic factors. we report a 47-year-old woman with a history of dilated cardio...

conclusion the study data highlighted good value of iodine-based material decomposition images of spectral ct in assessment of both lipiodol deposition and residual cancer for follow-up of hcc patients previously treated with tace. background it is critical to follow up hepatocellular carcinoma (hcc) after transcatheter arterial chemoembolization (tace) in clinical practice. computed tomography...

conclusion using standard imaging parameters, each mri sequence reaches its maximum si in a specific contrast concentration, which is highest in se and least in ir in a comparison between se, fse and ir sequences. results this study shows that maximum si will appear at different ranges in different sequences. the maximum si can be seen at concentrations of 5.95, 4.96 and 3.98mmol/l for se, fse ...

intracystic carcinoma of the breast is a rare form of breast carcinoma. among all malignant breast tumors, this lesion has an incidence of 0.2-0.5%. these neoplasms have certain characteristic imaging findings which help to differentiate these lesions from other focal breast abnormalities. this report is on the case of a 48-year-old woman with a palpable, painless lump in her right breast. mamm...

we report an unusual case of hemimegalencephaly (hmg) associated with ipsilateral congenital-infiltrating lipomatosis of the face in a five-month-old boy. hemimegalencephaly is a rare but unique malformation characterized by enlargement of all or parts of a cerebral hemisphere. the affected hemisphere may have focal or diffuse neuronal migration defects, with areas of polymicrogyria, pachygyria...

T ∗ 2 -weighted functional MR images are plagued by signal loss artifacts caused by susceptibility-induced through-plane dephasing. We present major advances to the original threedimensional tailored RF (3DTRF) pulse method that precompensates the dephasing using three-dimensional selective excitation. The proposed 3DTRF pulses are designed iteratively with off-resonance incorporation and with ...
