	~~The~~ DMSA scan ~~procedure involves~~ the ~~injection~~ of the ~~DMSA tracer into a vein, usually~~ in ~~the arm~~.

	~~==Uses==~~		[[File:DMSA_scan.jpg\|thumb\|right\|A typical DMSA scan showing renal uptake of the tracer.]]
	A DMSA scan ~~is used to evaluate the function and structure~~ of the ~~kidneys. It can help diagnose a number of kidney conditions, including [[kidney infections]], [[kidney stones]], and [[kidney damage]]~~. ~~It can also be used to assess the kidneys before and after [[kidney transplant~~]] ~~surgery.~~

	==~~Risks~~==		===Procedure===
	~~As with any medical~~ procedure~~, there are some risks associated with~~ a DMSA scan. ~~These include an allergic reaction~~ to the ~~DMSA~~ tracer ~~and exposure~~ to a ~~small amount of~~ radiation~~. However,~~ the ~~benefits of a DMSA scan usually outweigh these risks~~.		The procedure for a DMSA scan involves the intravenous injection of the DMSA tracer. After the injection, there is a waiting period, usually 2 to 4 hours, to allow the tracer to be absorbed by the kidney tissue. The patient then undergoes imaging with a [[gamma camera]], which detects the gamma radiation emitted by the tracer.

	==~~Preparation~~==		===Clinical Applications===
	~~Before a~~ DMSA ~~scan, patients~~ are ~~usually asked~~ to ~~drink plenty of fluids~~ to ~~help the kidneys work more effectively~~. ~~They may also be asked to avoid certain medications that could interfere with the scan~~.		DMSA scans are primarily used to:
			* Detect renal cortical scarring, often due to [[pyelonephritis]] or [[urinary tract infection]]s.
			* Assess differential renal function, which is important in conditions such as [[vesicoureteral reflux]] and [[obstructive uropathy]].
			* Evaluate renal masses or anomalies.

	==~~Results~~==		===Interpretation===
	The ~~results of~~ a DMSA scan ~~are usually available within a few days. The images from~~ the ~~scan can show any abnormalities in~~ the kidneys, ~~such~~ as ~~areas~~ of damage ~~or infection~~.		The images obtained from a DMSA scan provide information about the size, shape, and position of the kidneys, as well as the presence of any scarring or defects. Areas of decreased uptake may indicate scarring or damage to the renal cortex.

	==~~See also~~==		===DMSA Scan While on Enalapril===
			In some cases, a DMSA scan may be performed while the patient is on [[enalapril]], an [[angiotensin-converting enzyme inhibitor]]. This can help assess the impact of the medication on renal function, particularly in patients with [[renal artery stenosis]].

			==Advantages and Limitations==
			The DMSA scan is highly sensitive for detecting renal cortical abnormalities and provides detailed anatomical information. However, it involves exposure to ionizing radiation, and the availability of the test may be limited in some regions.
