Study Notes

Contrast and Special Radiological Procedures

This book details special radiological procedures for various body parts to diagnose conditions like strictures, perforations, and tumors. It covers soft tissues such as kidneys, gallbladder, and the gastrointestinal tract (GI Tract) and examines arteries, veins, and other indications.
The book also discusses the effects of radiological contrast media on the body.
The author, Ayush Gupta, is an experienced professor in radiological procedures, having performed approximately 500 procedures.
The book is published by Lambert Academic Publishing.
The book includes a table of contents with page numbers for each topic.
The pages include content on various radiological procedures such as barium swallow, barium meal, barium enema, IVP, RGU, MCU, nephrogram, and other special investigations like sialography, dacrocystography, bronchography, arthrography, HSG, myelography, and oral cholecystography.
The book provides information on radiological contrast media, their history, types, and effects on the body; Requirements of a "perfect" contrast media are analyzed.
Contrast media is categorized into negative and positive types.
Negative contrast media are radiolucent and less dense than body tissue. Gases, such as air, are commonly employed.
Positive contrast media are radiopaque and more dense than body tissue. Barium and iodine-based solutions are employed for positive contrast visualization.
The book also covers details on barium suspensions, solutions, and their use for visualization of gastrointestinal imaging, safety concerns, potential side effects, contraindications, and considerations.
The book offers information on iodine based contrast media, including ionic and non-ionic types, to enhance the understanding of contrast application and use in medical imaging.
