What a Difference a Delay Makes! CT Urogram: a Pictorial Essay
Abdominal Radiology (2019) 44:3919–3934 https://doi.org/10.1007/s00261-019-02086-0 SPECIAL SECTION : UROTHELIAL DISEASE What a diference a delay makes! CT urogram: a pictorial essay Abraham Noorbakhsh1 · Lejla Aganovic1,2 · Noushin Vahdat1,2 · Soudabeh Fazeli1 · Romy Chung1 · Fiona Cassidy1,2 Published online: 18 June 2019 © This is a U.S. Government work and not under copyright protection in the US; foreign copyright protection may apply 2019 Abstract Purpose The aim of this pictorial essay is to demonstrate several cases where the diagnosis would have been difcult or impossible without the excretory phase image of CT urography. Methods A brief discussion of CT urography technique and dose reduction is followed by several cases illustrating the utility of CT urography. Results CT urography has become the primary imaging modality for evaluation of hematuria, as well as in the staging and surveillance of urinary tract malignancies. CT urography includes a non-contrast phase and contrast-enhanced nephrographic and excretory (delayed) phases. While the three phases add to the diagnostic ability of CT urography, it also adds potential patient radiation dose. Several techniques including automatic exposure control, iterative reconstruction algorithms, higher noise tolerance, and split-bolus have been successfully used to mitigate dose. The excretory phase is timed such that the excreted contrast opacifes the urinary collecting system and allows for greater detection of flling defects or other abnormali- ties. Sixteen cases illustrating the utility of excretory phase imaging are reviewed. Conclusions Excretory phase imaging of CT urography can be an essential tool for detecting and appropriately characterizing urinary tract malignancies, renal papillary and medullary abnormalities, CT radiolucent stones, congenital abnormalities, certain chronic infammatory conditions, and perinephric collections. -

Magnetic Resonance Imaging (MRI) – Urogram
Magnetic Resonance Imaging (MRI) – Urogram What is a Magnetic Resonance Imaging (MRI) Urogram? Definition A Magnetic Resonance Imaging (an MRI) Urogram creates images of the kidneys, the ureters (tubes that transport urine from the kidneys to the bladder), and the bladder in order to evaluate their condition and to assist with the diagnosis and treatment of problems. An MRI Urogram is very similar to the procedure known as an Intravenous Pyelogram (both creates images of the kidneys, ureters, and bladder and are used to measure their functioning), but it is also different in several important ways (namely, that the Intravenous Pyelogram uses x-rays to create images, whereas an MRI Urogram uses magnetic waves to create its images). An MRI Urogram can be used for patients who are allergic to iodine or other materials used in the contrast dye for x-rays (because the contrast dye used in MRIs is gadolinium) and for patients with renal failure or renal transplant patients. How It Works During an MRI Urogram, a technician will inject a contrast material (dye) into the body via an IV (intravenous drip). The contrast material contains a magnetic substance. When the MRI equipment is put in motion, the contrast material reacts to the magnets to reveal the details of the structures within and around the area being examined, similar to the way x-rays create images of bones. The difference is an MRI uses a powerful magnetic field and radiofrequency pulses to create detailed pictures, whereas an x-ray uses radiation. Often, before an MRI Urogram a catheter is inserted through the urethra (opening through which urine leaves the body) into the bladder to make sure the bladder remains empty during the test, so the best possible images can be captured. -

DISSERTATION INVESTIGATION OF CATIONIC CONTRAST-ENHANCED COMPUTED TOMOGRAPHY FOR THE EVALUATION OF EQUINE ARTICULAR CARTILAGE Submitted by Bradley B. Nelson Department of Clinical Sciences In partial fulfillment of the requirements For the Degree of Doctor of Philosophy Colorado State University Fort Collins, Colorado Fall 2017 Doctoral Committee: Advisor: Christopher E. Kawcak Co-Advisor: Laurie R. Goodrich C. Wayne McIlwraith Mark W. Grinstaff Myra F. Barrett Copyright by Bradley Bernard Nelson 2017 All Rights Reserved ABSTRACT INVESTIGATION OF CATIONIC CONTRAST-ENHANCED COMPUTED TOMOGRAPHY FOR THE EVALUATION OF EQUINE ARTICULAR CARTILAGE Osteoarthritis and articular cartilage injury are substantial problems in horses causing joint pain, lameness and decreased athleticism resonant of the afflictions that occur in humans. This debilitating joint disease causes progressive articular cartilage degeneration and coupled with a poor capacity to heal necessitates that articular cartilage injury is detected early before irreparable damage ensues. The use of diagnostic imaging is critical to identify and characterize articular cartilage injury, though currently available methods are unable to identify these early degenerative changes. Cationic contrast-enhanced computed tomography (CECT) uses a cationic contrast media (CA4+) to detect the early molecular changes that occur in the extracellular matrix. Glycosaminoglycans (GAGs) within the extracellular matrix are important for the providing the compressive stiffness of articular cartilage and their degradation is an early event in the development of osteoarthritis. Cationic CECT imaging capitalizes on the electrostatic attraction between CA4+ and GAGs; exposing the proportional relationship between the amount of GAGs present within and the amount of CA4+ that diffuses into the tissue. The amount of CA4+ that resides in the tissue is then quantified through CECT imaging and estimates tissue integrity through nondestructive assessment. -
Intravenous Pyelogram (IVP)
Intravenous Pyelogram (IVP) Intravenous pyelogram (IVP) is an x-ray exam that uses an injection of contrast material to evaluate your kidneys, ureters and bladder and help diagnose blood in the urine or pain in your side or lower back. An IVP may provide enough information to allow your doctor to treat you with medication and avoid surgery. Inform your doctor if there's a possibility you are pregnant and discuss any recent illnesses, medical conditions, medications you're taking and allergies, especially to iodine-based contrast materials. Your doctor may instruct you to take a mild laxative the evening before the exam and to not eat or drink anything after midnight. Wear loose, comfortable clothing and leave jewelry at home. You may be asked to wear a gown. What is an Intravenous Pyelogram (IVP)? An intravenous pyelogram (IVP) is an x-ray examination of the kidneys, ureters and urinary bladder that uses iodinated contrast material injected into veins. An x-ray exam helps doctors diagnose and treat medical conditions. It exposes you to a small dose of ionizing radiation to produce pictures of the inside of the body. X-rays are the oldest and most often used form of medical imaging. When contrast material is injected into a vein in the patient's arm, it travels through the blood stream and collects in the kidneys and urinary tract, turning these areas bright white on the x-ray images. An IVP allows the radiologist to view and assess the anatomy and function of the kidneys, ureters and the bladder. What are some common uses of the procedure? An intravenous pyelogram examination helps the radiologist assess abnormalities in the urinary system, as well as how quickly and efficiently the patient's system is able to handle fluid waste. -

Pyelography in Infants
Arch Dis Child: first published as 10.1136/adc.9.50.119 on 1 April 1934. Downloaded from PYELOGRAPHY IN INFANTS BY W. E. UNDERWOOD, F.R.C.S., Chief Assistant to a Surgical Unit, St. Bartholomew's Hospital. Pyelography in infants is an examination which is essential under certain circumstances, and from it valuable facts may often be obtained which would be undiscovered without this specialized form of investigation. Hitherto the examination has been surrounded by difficulties of such a nature that it is often unsuccessful and the child is submitted to discomfort without result. The object of this paper is to bring forward certain notes on cases where pyelography has been indicated. The observations from a series of sixteen cases have led to the development of a method whereby good pyelograms have been obtained with certainty. Instrumental pyelography in infancy is a procedure not to be advised lightheartedly, but there are occasions where the indications are definite and adequate: in these cases the anticipation of possible information to be gained justifies submitting the infants to what constitutes a major examination. In this series are cases of urinary infection resistant to the usual medical treatment, of renal pain, of renal calculi, and cases of congenital malformation http://adc.bmj.com/ of the urinary tract similar to those described by Poynton and Sheldon'. The term pyelography is used here for brevity rather than accuracy, for it embraces a complete investigation of the urinary tract, including ureterography.
