OBJECTIVE The objective of our study was to evaluate the diagnostic agreement, the impact on decision making, and the costs of contrast-enhanced MR angiography and digital subtraction angiography in the workup of living renal donors. CONCLUSION Contrast-enhanced MR angiography for the preoperative evaluation of renal donors is superior to digital subtraction angiography in revealing vascular ...

PURPOSE Laser-targeted angiography has unique advantages over conventional angiography of the fundus. Its efficacy in visualizing choroidal neovascular membranes was tested in a rat model and compared to that of fluorescein angiography. METHOD Laser-targeted angiography was performed in rats with choroidal neovascularization (CNV) by injecting heat-sensitive carboxyfluorescein liposomes intra...

BACKGROUND AND PURPOSE Vertebral stenosis is associated with a high risk of recurrent stroke, but noninvasive imaging techniques to identify it have lacked sensitivity. Contrast-enhanced MR angiography and CT angiography have been recently developed and appear to have better sensitivity. However, no prospective studies have compared both of these techniques with ultrasound against the gold stan...

BACKGROUND AND PURPOSE MR angiography is primarily and increasingly used to assess intracranial arterial stenoocclusion. However, MR angiography can cause overestimation of stenosis. Although CT angiography is accurate, it has limitations. Our purpose was to determine whether the accuracy of combined MR angiography and CT angiography is equal to that of digital subtraction angiography (DSA) in ...

BACKGROUND AND PURPOSE The value of MR angiography varies in diagnosis of intracranial aneurysms due to the difference of equipment and imaging technique. This study was to compare the effectiveness of 3-dimensional time-of-flight MR angiography at 3 T and rotational digital subtraction angiography, both with volume rendering (VR), in detecting intracranial aneurysms. METHODS One hundred thir...

BACKGROUND AND PURPOSE Previous studies have depicted arterial and aneurysmal anatomy with three-dimensional time-of-flight (3D-TOF) MR angiography before and after treatment with Guglielmi detachable coils (GDCs) and with CT angiography before and after treatment with stents and stent-grafts. We investigated the ability of time-resolved contrast-enhanced 3D MR angiography (3D MR digital subtra...

OBJECTIVES This study was conducted to evaluate the clinical value of computed tomographic (CT) angiography for diagnosis and therapeutic planning in patients with pulmonary sequestration. METHODS Forty-three patients with suspected pulmonary sequestration underwent CT angiography before undergoing digital subtraction angiography or surgery. For each patient, CT angiography was used to determ...

background: percutaneous nephrolithotomy (pcnl) for renal calculi is less invasive treatment than open surgery. vascular complications of this procedure include hematoma, pseudoaneurysm and arteriovenous fistula of which pseudoaneurysm is usually symptomatic 24h after procedure. case report : we report a case of pseudoaneurysm, which was symptomatic within less than 24h following procedure and ...

Prom April, 1983 until December, 1987, 15 patients with horseshoe kidneys underwent surgery in Shahid Labbafi Nejad Medical Center. Pyelolithotomy was done in 11 cases, pyeloplasty in 2 cases, and nephrectomy in 2 cases. Symphysiotomy was performed in 14 of these patients. Preoperative angiography was not done in any of the cases and midline transperitoneal approach was utilized in all of ...

Background: Cystatin C (Cys C) as a cysteine protease inhibitor is produced in a constant level from all nucleated cells. The purpose of this study was to investigate the correlation between serum levels of Cys C and coronary slow flow (CSF) and body mass index (BMI) in men. Methods: This investigation is in the form of a descriptive-analytical study. The statistical population was all non-act...
