    Allgemeines Die Nuklearmedizin bietet unterschiedliche Methoden der szintigraphischen Nierenuntersuchung. Die jeweilige Fragestellung bestimmt die Untersuchungsart, den Untersuchungsablauf und das dazu erforderliche Radiopharmakon. Aufgrund der äußerst geringen Strahlenbelastung ist diese Methode bei Kindern die am häufigsten angewendete nuklearmedizinische Untersuchung. Funktionsweise Bei der "normalen" Nierenszintigraphie wird mit Hilfe eines tubulär sezenierenden Radiopharmakons die Gewebs- und Ausscheidungsfunktion (Exkretion) der Nieren untersucht. Hierbei erfolgen die seitengetrennte Überprüfung der Nierenfunktion, die Clearance-Messung und die Beurteilung des Abflussverhaltens. Bei zusätzlicher Gabe eines harntreibenden Medikamentes (Lasix®) kann zwischen einer funktionellen und einer obstruktiven Abflussstörung unterschieden und die urodynamische Relevanz dieser Störung beurteilt werden. Bei Verdacht auf eine einseitige Nierenarterienstenose (Engstelle in der Nierenarterie) als Ursache einer Hypertonie, kann eine hämodynamische Relevanz dieser Stenose ermittelt werden, wenn die zusätzliche Gabe eines ACE-Hemmers erfolgt. Genannt, ist ein nuklearmedizinisches Untersuchungsverfahren, das die Beurteilung der Nierenfunktion unter statischen und dynamischen Gesichtspunkten erlaubt. Beurteilt werden dabei die Blutversorgung, Funktion und Exkretion jeder einzelnen Niere. Es ist die am besten geeignete Untersuchung zur Erkennung von Parenchymnarben, insbesondere bei Kindern, und dient weiter zur Beurteilung der regionalen und seitengetrennten Nierenfunktion. Grundsätzlich sind zwei Formen der Nierenszintigrafie zu unterscheiden. Die statische und die dynamische Nierenszintigrafie. Bei der statischen Nierenszintigrafie wird unter Verwendung des Radionuklids Tc-DMSA (DMSA = 2,3-Dimercaptosuccinsäure) das funktionsfähige Nierengewebe dargestellt. Die statische Nierenszintigrafie eignet sich daher vor allem zur Darstellung von Nieren mit Anomalien (Dystopie, Hufeisenniere etc.) oder von dem Zustand nach Entzündung. Die Injektion des Radionuklids erfolgt etwa zwei Stunden vor der Messung mit der Gammakamera.

Learn how a Lasix renal scan is done and how it shows how the kidneys are working. Hydronephrosis on the right. • His pediatrician ordered a lasix renogram. Which radionuclide class should be used for the scan? • A filtered radionuclide is used.

    In a nuclear medicine renal scan, images, or pictures, are taken of fluid going into the kidneys through the bloodstream, the filtered wastes from the blood in the kidneys and the flow or drainage of the waste into the bladder through the ureters (that join the kidneys to the bladder). A nuclear medicine renal scan uses radiopharmaceuticals (radioactive medications) injected into a vein, usually in the arm, to provide clear images of the kidneys taken with a special camera called a gamma camera. The scan can be carried out using one of two different radiopharmaceuticals – DTPA (diethylene triamine pentaacetic acid) or MAG3 (mercaptoacetyletriglycine). They are similar medications, but MAG3 gives significantly clearer images in some patients, particularly very young children and those patients with poor kidney function. Your doctor will refer you for a nuclear medicine renal scan to look at the blood supply, function and flow of urine from the kidneys if it is suspected that there are problems with how your kidneys are working. Reduced kidney function may be shown in abnormal blood tests, high blood pressure or abnormal results obtained from the urine itself. It is important before having the scan that you drink plenty of fluids, so the gamma camera can take images of the fluid as it is collected in the kidneys and discharged through the ureters and into the bladder. A nuclear renal scan examines the blood flow and function of the kidneys using a Radiopharmaceutical (also called tracers or DTPA). This is a small amount of a radioactive chemical that is injected into an arm vein. A gamma camera placed over the kidneys then maps or takes images of the pattern of tracer passing through the kidneys, giving information useful in diagnosing conditions such as obstruction. If there is any possibility of obstruction in the urinary system, an injection of Lasix may be given after the first 20 to 30 minutes of imaging to temporarily increase the kidneys' function, and allow further imaging to confirm how quickly the kidneys "wash out". When you attend your appointment at Global Diagnostics you will be asked to answer a few safety questions, remove any jewellery, watches etc, then change into an examination gown. The technologist will explain the scanning procedure and position you for the scan. The radioactive tracer will then be injected into an arm vein using an intravenous cannula.

    I don't recall which test it was, but I believe the Herpes Select test is the most common one, so I would assume that was the test I was given. But both before and during the time I've taken Valtrex I don't think I've ever had an outbreak of Herpes, I've never seen any genital lesions or had any coldsores. So I've always wondered if there is a chance that I don't really have Herpes. As much as he can transmit HSV2 to you, you could transmit HSV1 to him!! You are less likely to transmit the infection to him since the shedding rate is lower but at the same time, he is more opt to shedding 2 to you if he isn't on Valtrex so you both need to sit down and be honest!! Except the first ob, I had one in 2010 after my surgery to remove fibroids, then I had twice sexual relations with condoms that triggered me an herpes only after three days. The second time I immediately took Valtrex so after one day I was perfectly fine. When I have an ob after sex with condom the entry of my vagina closes itself and won't allow penetration. It seems that my only trigger for ob will be sex, or will be the condom. Well we been together now 7 years and I have not shown any symptom of HSV2. We have frequent sex and she uses her valtrex only when she feels a possibility of an outbreak forming.
