SUMMARY The widespread use of high-resolution, real time ultrasound has enabled physicians to identify a variety of fetal anatomy abnormalities. About 15-25% of fetal diseases can be diagnosed and even treated antenataly. This is a report of a case with fetal ovarian Cyst which has been confirmed with ultrasonography both antcnataly and postantaly, and caused intestinal obstruction in neonate...

In this study we investigate the ability of Natural Killer (NK) cells to form ultrasound-mediated intercellular contacts with target cells in a multi-well microdevice by high-resolution confocal-microscopy imaging of inhibitory immune synapses. Furthermore, we compare the NK-Target cell cluster migration with and without ultrasound actuation. Experiments indicate that clusters of cells are posi...

introduction: the medical applications of ultrasound on human brain are highly limited by the phase and amplitude aberrations induced by the heterogeneities of the skull. however, it has been shown that time reversing coupled with amplitude compensation can overcome these aberrations. in this work, a model for 2d simulation of the time reversal mirror technique is proposed to study the possibil...

background: hemodialysis is a process of removing waste and excess fluid from blood when kidneys cannot function efficiently. it often involves diverting blood to the filter of the dialysis machin to be cleared of toxic substances. fouling of pores in dialysis membrane caused by adhesion of plasma protein and other toxins will reduce the efficacy of the filtre. objective: in this study, the inf...

hepatic inflammatory pseudotumor (ipt) is a rare non-neoplastic process of unknown etiology, generally following a benign inflammatory condition. it is often mistaken as an either primary or metastatic malignancy in imaging studies. we report a 48 year-old female with numerous target lesions (2-4 cm) seen on high resolution ultrasound, spiral ct scan, and mri in all liver lobes compatible with ...

orbital lynphangioma is a low-flow or no-flow vascular malformation. it is a congenital and isolated hemodynamic lesion in which the clinical presentation and onset are related to orbital, peri-orbital or intracranial involvement. in addition, history of previous trauma and upper respiratory tract infection are important predictor factors. high resolution mri, doppler ultrasound and ct-scan are...

Background: Rib osteomyelitis is a very rare form of pediatric osteomyelitis. Case report: Herein, we reported a very rare case of chest wall abscess with rib osteomyelitis and rib destruction due to Staphylococcus aureus infection in a 14-day-old preterm male neonate. The diagnosis of this uncommon disease requires a high index of suspicion due to its rarity and non-specific clinical presenta...
