Objective(s): In this study, we aimed to describe the characteristics of portal vein tumor thrombosis (PVTT), complicating hepatocellular carcinoma (HCC) in contrast-enhanced FDG PET/CT scan. Methods: In this retrospective study, 9 HCC patients with FDG-avid PVTT were diagnosed by contrast-enhanced fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT), which is a comb...
Objective(s): This study aimed to show the effects of thymoquinone, which is known for its antioxidant, anti-inflammatory, and renal protective effects in contrast-induced nephropathy.Materials and Methods: This is an experimental study in rats. 7 groups were included within the scope of our study: sham-vehicle (n=3), premedication-contr...
background: contrast induced nephropathy (cin) is one of the most common complications after radiographic procedures using intravascular radiocontrast media. the aim of the current study was to assess the effect of atorvastatin on prevention of cin in patients undergoing coronary angiography. materials and methods: in a clinical trial study, 200 patients referred for angiography were randomly d...
BACKGROUND AND AIM: Digital panoramic X-ray images can be captured using photostimulable phosphors or solid-state detectors (i.e. charge-coupled devices and Flat-Panels). The first category is defined as computed radiography (CR) or semi-direct radiography. The second technology that uses solid-state detectors is known as direct digital radiography (DDR). Both of these technologies have their o...
Irrational use of medicines is a major problem worldwide. Since iodixanol (Visipaque®) was categorized in Category I (AV) based on the ABC-VED analysis in our hospital, we evaluated the amount of visipaque use and estimated the incremental cost based on the maximum contrast dose (MCD) following irrational use of contrast media. This retrospective study was conducted on 100 admitted patients age...
background: nowadays mri examinations have been widely used in clinical applications for many diagnoses. the use of contrast agent in mri improves lesion detection and characterization and causes more accurate diagnosis. objectives: the aim of this study was comparing to optimal dose of magnevist contrast agent in modified t1w se (spin echo), t1w fse (fast spin echo) and t1w gre (gradient ech...
Background & Aim: Molecular imaging enables us to non-invasively visualize tissue microstructures and lesion characterization, allowing accurate diagnosis of diseases at early stages. A successful molecular imaging requires a nontoxic contrast agent with high sensitivity. Nowadays, a wide range of nanoparticles have been developed as contrast agents for medical imaging modalities. Here, we revi...
