The incidence of transient cortical blindness, a rare but known complication of iodinated contrast agents, is reported to be between 0.3% and 1% for certain procedures [1.2.2]. So, can contrast dye cause eye problems? While severe issues are uncommon, a range of ocular side effects can occur.

While serious adverse reactions to iodine contrast dye after a CT scan are rare, occurring in less than 1% of patients, it is common to experience mild, temporary side effects. The potential reactions can vary significantly in severity, from a warm sensation and metallic taste to more serious issues affecting the kidneys or triggering allergic responses.

While most patients tolerate it well, a small percentage of individuals receiving an intravenous (IV) contrast agent experience a delayed reaction that can include mild gastrointestinal side effects. This raises the question, **Can IV contrast cause diarrhea?**

Used extensively in modern diagnostic medicine, Omnipaque (iohexol) is an iodinated contrast agent designed to enhance the visibility of internal body structures during medical imaging. In fact, it is relied upon by radiologists and physicians worldwide to improve the clarity of images from a variety of scans, leading to more accurate diagnoses.

Adverse reactions to Fludeoxyglucose F 18 (FDG) are uncommon, with severe allergic reactions being very rare. It is important to know what are the side effects of FDG to feel prepared and confident before your positron emission tomography (PET) scan.

According to the Journal of Nuclear Medicine, proper patient preparation is a critical step towards obtaining good quality images and accurate results during a PET scan. This guide explains what medications should I avoid for a PET scan and offers a comprehensive overview of how certain drugs, particularly diabetes medications, can interfere with the imaging process.
