There are several chapters dealing with a wide range of topics, including patient selection and preparation strategies, adverse effects of iodinated contrast media, contrast nephrotoxicity, contrast media in children, iodinated gastrointestinal contrast media, nephrogenic systemic fibrosis, treatment of contrast reactions, etc. Educative tables are also available concerning the indications for the use of iodinated contrast media, categories of reactions, an ABCD approach for patient evaluation and treatment, management of acute reactions in adults, and equipment for emergency carts.
  3. Radiography is an educational portal from SUNY Upstate Medical University, Syracuse, NY and available at . It has several sections covering techniques, X-ray tube voltage (kV), current-exposure time product (mAs), resolution, focal spot pixel size, scatter and its relationship with collimation, kV, and dual-energy radiography. Special sections on exposure and image artifacts are also available. A feature on radiographic artifacts is on offer at .
  4. E-radiology at  is authored by Gillian Lieberman, from the Department of Radiology, Beth Israel Deaconess Medical Center. There are educative sections titled Interactive Tutorials in Radiology, Classics Collection, Learning Lab, and Living Anatomy. Sections covering assessment of abdominal pain, chest pain, low back pain, hematuria, breast imaging, diabetes, and AIDS are also available. On offer is a dedicated section on MRI  Atlas More Details of the Abdomen and Chest Anatomy for first-year students. Classics collection is 'a compendium of images demonstrating the classic radiological findings of a multitude of abnormalities.'
  5. Radiology Masterclass , sourced at , is 'a growing resource in medical imaging teaching. There are educative tutorials dealing with chest X-ray, abdomen X-ray, general X-ray tutorials, basics of X-ray physics, objective structured clinical examination (OSCE) presentation tips, intravenous urogram (IVU) guide, common fractures, common orthopedic conditions, etc.
  6. Clinical Practice Guidelines at  is a quality improvement initiative offered by the Society of Interventional Radiology (SIR) and deals with safety guidelines, consensus, policy and position and standards. The documents that facilitate quality improvement make up a long list and include guidelines for establishing a quality improvement program in interventional radiology, for percutaneous needle biopsy, for central venous access, for transcatheter embolization, for percutaneous transhepatic cholangiography, for biliary drainage and percutaneous cholecystostomy, for transjugular intrahepatic portosystemic shunt (TIPS), for reporting and archiving of interventional radiology procedures, for percutaneous management of acute limb ischemia, and for reducing radiation risks for patients and staff. There is also a clinical expert consensus document on carotid stenting.
  7. Ultrasoundpedia at  is 'a portal to a world of ultrasound education, and is intended for sonographers, sonologists, and practitioners.' The site 'provides up-to-date ultrasound education and links to quality useful sites.' Illustrative sections on upper abdomen, urology, gynecology, obstetrics, musculoskeletal system, vascular system, and small parts are available here.
