What are Nephrograms?

[ nĕf′rə-grăm′ ] n. A radiograph of the kidney following the intravenous injection of a radiopaque substance.

What is the Nephrogram phase?

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.

What is prompt Nephrogram?

Discussion. On the initial nephrogram images, a large amount of uptake was noted in the right kidney (this is known as a “prompt nephrogram”); however, on the left side, a delay of uptake into the kidney parenchyma was observed (known as a “delayed nephrogram”).

What is a delayed Nephrogram?

A delayed nephrogram, commonly described on plain film urography, but also visible on CT urography, is when there is absence or reduction of the normal renal parenchymal enhancement on the nephrographic phase images.

What is a Renogram test?

A renogram is a test used to assess function in the kidneys. Special pictures are taken after a medicine is injected into a vein. The medicine is called a radiopharmaceutical (a tiny amount of a radioactive liquid). The pictu​res show the medicine in the kidneys.

What is Pyelographic phase?

The pyelographic or excretory phase is present 3 minutes after in- jection of IV contrast material (Fig. 1). In normal kidneys, the three phases of contrast media excretion are always symmet- ric in time of appearance, time of disappear- ance, and density [2].

What is cortico medullary?

Corticomedullary definition (anatomy) Relating to, or joining, the renal medulla and cortex.

What is Pelvicalyceal system?

It means the part of kidney draining urine to ureter(connecting tube between kidney and urinary bladder)is dilated..it may be a temporary dilation or due to some obstruction of urine flow Read More.

What is renogram used for?

A renogram is a nuclear medicine test of the kidneys. It can be used to see how well each kidney is working and whether urine passes on into the bladder without obstruction.

How is renogram done?

A renogram or renal scan is a test that uses a radioactive substance (or tracer) to examine your kidneys and their function. The scan evaluates the blood flow through the kidneys and measures the amount of time it takes for the tracer to move through the kidneys, collect in the urine and drain into the bladder.
