Summary
This review covers myelography contrast media history. Newer water-soluble agents like Metrizamide (Amipaque) show fewer adverse reactions compared to older, non-absorbable or less accepted options.
Area of Science:
- Radiology
- Medical Imaging
- Neurology
Background:
- Myelography utilizes contrast media for spinal canal imaging.
- Historical contrast agents have varied absorption and side effect profiles.
- Adverse reactions to contrast media have driven the development of safer alternatives.
Purpose of the Study:
- To review the historical evolution of contrast media used in myelography.
- To compare the safety and efficacy of different myelographic contrast agents.
- To highlight the development and benefits of newer contrast media.
Main Methods:
- Literature review of historical and current myelographic contrast agents.
- Analysis of reported side effects and absorption characteristics.
- Comparison of reaction rates between different contrast media types.
Main Results:
- Air is safely absorbed; Lipiodol and Pantopaque cause arachnoiditis due to non-absorption.
- Diodrast and Thorotrast had limited acceptance; Dimer-X and Conray 60 cause reactions.
- Metrizamide (Amipaque), a new nonionic water-soluble agent, demonstrates fewer adverse reactions.
Conclusions:
- Contrast media for myelography have evolved significantly over time.
- Nonionic water-soluble agents like Metrizamide represent an advancement in patient safety.
- Metrizamide offers a favorable safety profile compared to previous myelographic contrast agents.

Imaging Studies for Cardiovascular System IV: CMRI
Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...
Imaging Studies III: Computed Tomography
DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...
Imaging Studies IV: Magnetic Resonance Imaging
Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...
Imaging Studies VII: Vascular Imaging
DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...
