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 infl...

Background:Prenatal ultrasound plays an important role in the early and accurate evaluation of the congenital skeletal and non-skeletal abnormalities of the fetus and is effective in predicting pregnancy outcomes. Congenital femoral deficiency (CFD) is a rare complicated and non-hereditary anomaly that includes the hypoplasia of a portion of the femoral bone with shortening the lower limb. Cas...

Background: Drug nano-carriers are one of the most important tools for targeted cancer therapy so that undesired side effects of chemotherapy drugs are minimized. In this area, the use of ultrasound can be helpful in controlling drug release from nanoparticles to achieve higher treatment efficiency.Objective: Here, we studies the effects of ultrasound irradiation on the release profile of 5-flu...

urinary tract infections are common in children. the available gold standard method for diagnosis, tc-99m dimercaptosuccinic acid scan is expensive and exposes patients to considerable amount of radiation. this study was performed to compare and assess the efficacy of power doppler ultrasound versus tc-99m dmsa scan for diagnosis of acute pyelonephritis. a quasi experimental study was conducted...

ultrasound guidance for pain interventions is becoming increasing recognized as a useful imaging tool. one of the common interventions where it is gaining wider acceptance is during the performance of a stellate ganglion block. the following is a unique report where intravascular and neuronal injury occurred during the performance of an ultrasound guided stellate ganglion block followed by dysp...

purpose: to assess hoffer correction factor in measurement of axial length (al) in eyes with phakic iol implants. methods: in this descriptive historical cohort study, axial length was measured by ultrasound (us) and iol master in both phakic and pseudophakic modes in 24 eyes of 14 patients with artisan intraocular lenses (iols) implanted for refractive purposes, hoffer’s suggested formula for ...

  ABSTRACTBackground : In order to quantify effects of ultrasound irradiation parameters under therapeutic condition, especially sonodynamic therapy, it is initially necessary to evaluate inertial cavitation activity in vitro conditions therefore, in this study, the effect of 1 MHz low level ultrasound based on °OH radicals generated by acoustic inertial cavitation in aqueous solution was monit...

occipital neuralgia is a condition manifested by chronic occipital headaches and is thought to be caused by irritation or trauma to the greater occipital nerve (gon). treatment for occipital neuralgia includes medications, nerve blocks, and pulsed radiofrequency ablation (prfa). landmark-guided gon blocks are the mainstay in both the diagnosis and treatment of occipital neuralgia. ultrasound is...
