Take a laxative the evening before the procedure. The nephrogenic phase, also known as the nephrographic phase or the renal parenchymal phase, is a postcontrast injection time range in which there is an optimal enhancement of the renal parenchyma including the medulla. CT angiography of the chest (CTA chest) is a cross-sectional diagnostic examination that can be performed ECG-gated or non-ECG gated. A CT protocol is a set of parameters that specify a specific exam and contrast delivery requirements. MRU is not currently a widely applied technique of MRI, but given its favorable safety profile, use of existing sequences and software, and preliminary success, MRU may one day experience growth similar to that. It is similar to a voiding cystourethrogram (VCUG), and the difference between the studies is primarily one of emphasis; a cystogram focuses on the bladder and a VCUG focuses on the posterior urethra. CTU included true non-enhanced phase, dual-energy mode.

Recognizing the different nephrographic patterns on CT urography can be invaluable in understanding the morphologic and physiologic condition of the kidney and ultimately. MR urography is clinically useful in the evaluation of suspected urinary tract obstruction, hematuria, and congenital anomalies, as well as surgically altered anatomy, and can be particularly beneficial in. IVU has many drawbacks including poor diagnostic accuracy in diagnosis and characterization of parenchymal lesions, also in cases of nonfunctioning kidneys. Normally the ureter drains via the internal ureteral orifice at the trigone of the urinary bladder . The iodinated contrast flows through the renal vasculature and filtered into the collecting system highlighting the anatomic structures on the X-ray image. In most cases,Variant 2: Microhematuria. 1 Likewise, the American College of Radiology rated CTU as the most appropriate imaging procedure in the evaluation of hematuria.
