BACKGROUND This study is to investigate the feasibility of low iodine concentration contrast material (CM) combined with low tube voltage and adaptive statistical iterative reconstruction (ASIR) in renal computed tomography angiography (CTA). MATERIAL AND METHODS A total of 136 patients were enrolled in this prospective trial, and randomly divided into two groups: group A (n=68) and group B (n=...

Combined acute inhibition of the synthesis of nitric oxide with L-nitroarginine methyl ester (L-NAME) and of prostacycline synthesis with indomethacin predisposes rats to severe renal injury from radiographic contrast media. The reliability of this pharmacological manipulation in the study of radiographic contrast medium induced nephropathy (RCMN) was investigated. Adult male Sprague-Dawley rat...

BACKGROUND to study changes involving cerebral vessels in patients with hypertension and various levels of total cardiovascular risk. MATERIAL/METHODS One hundred and thirty-four patients underwent CT-angiography of intracranial vessels. Ninety-eight of them were diagnosed with hypertension. Taking into consideration high blood pressure, presence of risk factors and target organ damage subjec...

Correspondence To the Editor: Kounis syndrome describes a group of symptoms that manifest as unstable vasospastic or nonvasospastic angina or as acute myocardial infarction. It is triggered by the release of inflammatory mediators after an allergic reaction. A 74‑year‑old man with urinary incontinence was treated with a radical cystectomy using the Mainz pouch procedure and ureteroscopic lithot...

Iodinated X-ray contrast media (ICM), used medically to highlight soft tissues, are considered generally safe, and patients excrete 95% of the dose within 24 hours, making them a valuable tool in medical imaging. But a new study shows that excreted ICM react with chloramine and chlorine at water treatment plants to form toxic iodinated disinfection by-products (iodo-DBPs). 1 " ICM are definitel...

Iodinated X-ray contrast media (ICM) were investigated as a source of iodine in the formation of iodo-trihalomethane (iodo-THM) and iodo-acid disinfection by-products (DBPs), both of which are highly genotoxic and/or cytotoxic in mammalian cells. ICM are widely used at medical centers to enable medical imaging of soft tissues (e.g., organs, veins, blood vessels), they are almost completely excr...

To the Editor: We present 2 cases of bilateral swelling of the parotid glands appearing after application of contrast media. This unusual reaction is also known as Biodide mumps.[ As there is no premedication that can prevent its appearance, it is advisable in these cases to use imaging systems without iodide-based contrast media. The first case was a 70-year-old man with significant bilateral,...

Restenosis prevention continues to be a challenge in interventional cardiology. Clinical trials on drug eluting stents (DES) suppressing neointimal proliferation by sustained release of antiproliferative drugs have shown excellent results in reducing restenosis. DES are well accepted in the prevention and therapy of coronary restenosis. Meanwhile, concerns have been raised that DES while being ...
