Ct Scan Of The Head: About This Test

Ct Scan Of The Head: About This Test

A CT (computed tomography) scan uses X-rays to make detailed pictures of your body and the structures inside your body. A CT scan of the head can give your doctor information about your eyes, the bones of your face and nose, your inner ear, and your brain. During the test, you will lie on a table that is attached to the CT scanner. The CT scanner is a large doughnut-shaped machine. A CT scan of the head can help find the cause of symptoms that may mean you have a brain injury or bleeding inside your head. It can also find a tumour and damage caused by a stroke and help find the best treatment for the cause of a stroke. Talk to your doctor about all your health conditions before the test. For example, tell your doctor if: You get nervous in confined spaces. You may need medicine to help you relax. You may have to take off jewellery, glasses, or hearing aids. Wear comfortable, loose-fitting clothes. You may have contrast material (dye) put into your arm through a tube called an IV. Contrast material helps doctors see specific organs, blood vessels, and most tumours. You will lie on a table that is attached to the CT scanner. Straps will hold your head still but your face will not be covered. The table will slide into the round opening of the scanner. The table will move during the scan. The scanner moves inside the doughnut-shaped casing around your body. You will be asked to hold still during the scan. You may be asked to hold your breath for short periods. You may be alone in the scanning room, but a technologist will be watching you through a window and talking with you during the test. What else should you know about the test? If a dye is used, you may feel a quick sting or pinch when the IV is started. The dye may make you feel warm and flushed and give you a metall Continue reading >>

Metformin And Contrast Media: Where Is The Conflict?

Metformin And Contrast Media: Where Is The Conflict?

Abstract Intravascular administration of iodinated contrast media to patients who are receiving metformin, an oral antidiabetic agent, can result in lactic acidosis. However, this rare complication occurs only if the contrast medium causes renal failure, and the patient continues to take metformin in the presence of renal failure. Because metformin is excreted primarily by the kidneys, continued intake of metformin after the onset of renal failure results in a toxic accumulation of this drug and subsequent lactic acidosis. To avoid this complication, metformin must be withheld after the administration of the contrast agent for 48 hours, during which the contrast-induced renal failure becomes clinically apparent. If renal function is normal at 48 hours, the metformin can be restarted. There is no scientific justification for withholding metformin for 48 hours before administration of the contrast medium, as currently recommended in the package insert. The authors review the pharmacology of metformin and present a departmental policy for managing patients with diabetes who receive metformin and who require intravascular administration of iodinated contrast media.

Why Should I Stop Taking Metformin Before A Ct Scan?

Why Should I Stop Taking Metformin Before A Ct Scan?

Dear Pharmacist, I am currently taking metformin (Glucophage) for my type two diabetes. When scheduling an upcoming CT scan, my doctor told me not to take my metformin the morning of the study, as well as for two days following the scan. What’s the relationship? Dear Metformin, Depending on the specific purpose of the study, many CT scans require a dye or contrast to be injected into the patient prior to the scan. The dye will help highlight tissues so that more can be determined from the CT scan by your doctor. This dye, like the metformin, is filtered out of your blood by your kidneys for elimination from your body as waste. So in an attempt not to overload your kidneys, it is recommended that you do not take your metformin while your body is working to eliminate the dye from your body (approximately 48 hours). Taking the two together risks the possibility of the metformin building up in your body, which can lead to further severe side effects. Continue reading >>

CT scan is a sophisticated imaging tool utilizing x-rays and powerful computers to generate cross-sectional images of the body. CT scans are used to diagnosis wide range of diseases from head to toe. Spiral CT was introduced in the 1990's, which enable much faster and accurate scanning capabilities. Main Street Radiology installed the first 16-detector spiral CT in Queens, with the ability to scan up to 16 times faster than a traditional spiral CT. About the Procedure Depending on the type of scan requested by the referring physician, a patient may receive oral and/or intravenous (IV) contrast. Oral contrast is used to outline the stomach and intestines during the exam, and is given as a flavored drink approximately one hour prior to the actual scan. IV contrast is an iodine-based liquid injected into the vein during the scan to highlight organs of the body. The patient lies on a table that automatically moves the patient's body through a "donut" shaped tube, where a thin beam of x-rays is generated to produce high-resolution cross-sectional images of the body. The actual scanning time is usually less than 30 seconds with a 16-detector spiral CT. The patient may be asked to hold his/her breath during the scan, so that body part being imaged does not move during the scan acquisition. Preparation for Procedure To prepare for a CT scan, we ask that you follow the following guidelines: Please do not wear any item that is metal – including watches, hair pins, hearing aids, eyeglasses and jewelry. Please also do not wear any clothing that does not contain metal buttons, snaps or zippers. If you are, or think you may be pregnant please let us know as a CT scan is not generally performed on pregnant women.

The Editorial Executive Committee welcomes letters, which should be less than 250 words. Before a decision to publish is made, letters which refer to a published article may be sent to the author for a response. Any letter may be sent to an expert for comment. When letters are published, they are usually accompanied in the same issue by their responses or comments. The Committee screens out discourteous, inaccurate or libellous statements. The letters are sub-edited before publication. Authors are required to declare any conflicts of interest. The Committee's decision on publication is final. Letter to the editor Editor, – I write regarding the article dealing with radiographic contrast media (Aust Prescr 2010;33:19-22). I have recently authored a systematic review relating to the safety of iodinated contrast in patients receiving metformin.1 The review found no evidence to substantiate beliefs about the need to cease metformin in individuals with stable, normal renal function who were to have a 'normal' amount of intravenous iodinated contrast for an examination such as a CT scan. Despite a number of international guidelines having disparate recommendations about cessation of metformin, the Royal Australian and New Zealand College of Radiologists (RANZCR), the Royal College of Radiologists (RCR) and the European Society of Urogenital Radiology guidelines recommend that there is no need to stop metformin in these patients. The RANZCR recommendations are based on the extremely low risk of precipitation of contrast-induced nephropathy in this group. The Australian and RCR guidelines were modified along these lines in March and June 2009, respectively, soon after the systematic review was presented at the Radiological Society of North America meeting in December 2008.

Metformin And Contrast Medium

Metformin And Contrast Medium

To decrease your chance of developing lactic acidosis, you should temporarily stop taking metformin if you are going to undergo a procedure that uses a contrast medium. Because the contrast medium causes temporary damage to the kidneys (and because the kidneys remove metformin), contrast medium can greatly increase the level of metformin in the blood. An Overview of Metformin and Contrast Medium Metformin (Glucophage®) is a prescription medication licensed to treat type 2 diabetes. Due to an increased risk of a dangerous side effect called lactic acidosis, metformin should be temporarily stopped in people undergoing procedures involving contrast medium. What Is Contrast Medium? Contrast medium, also known as contrast dye, is used for certain radiology procedures. It is usually taken by mouth or injected, and helps to produce clear radiology images. Some common procedures involving contrast medium include: Certain computed tomography (CT) scans Cholangiography (a radiology procedure looking at the gallbladder or bile ducts) Intravenous urogram (used to look at the bladder or kidneys). Metformin and Contrast Dye Risks Contrast medium can be damaging to the kidneys. Usually, this damage is temporary and corrects itself quickly. However, because the kidneys remove metformin, contrast medium can greatly increase the level of metformin in the blood because damaged kidneys are not as effective at removing metformin from the body. High levels of metformin in the blood increase the risk of lactic acidosis (see Metformin and Lactic Acidosis). Because lactic acidosis is so dangerous, metformin should be temporarily stopped for procedures involving contrast medium.

Metformin And Iodinated Contrast: Lactic Acidosis Warning

Metformin And Iodinated Contrast: Lactic Acidosis Warning

Metformin and Iodinated Contrast: Lactic Acidosis Warning Have you wondered about the liquid given before a CT scan1 or X-ray procedure is done? Did someone give you an information sheet talking about the possible adverse drug effects? Any adverse drug effects if you are diabetic? Jay Harold will discuss an important warning from the Food and Drug Administration (FDA) about a diabetic medication (metformin) andIodinated contrast agents. A CT Scan uses a computer linked to an x-ray machine to make a series of detailed pictures of areas inside the body. The pictures are taken from different angles and are used to create 3-dimensional (3-D) views of tissues and organs. A dye may be injected into a vein or swallowed to help the tissues and organs show up more clearly. A CT scan may be used to help diagnose disease, plan treatment, or find out how well treatment is working. Also called CAT scan, computed tomography scan, computerized axial tomography scan, and computerized tomography. Iodinated contrast agents have been in use since the 1950s to facilitate radiographic imaging modalities. Physicians in almost all specialties will either administer these agents or care for patients who have received these drugs2. By far the most successful and widely applied contrast agents in use today are the iodinated contrast agents (ICAs), first introduced into clinical practice in the 1950s. It is estimated that approximately 75 million doses of ICAs are given worldwide each year. Metformin3 is used alone or with other medications, including insulin, to treat type 2 diabetes (condition in which the body does not use insulin normally and, therefore, cannot control the amount of sugar in the blood). Metformin is in a class of drugs called biguanides. Metformin helps to control the amount Continue reading >>

Metformin And Intravenous Contrast

Metformin And Intravenous Contrast

Go to: Metformin is excreted by the kidneys Metformin is used in type 2 diabetes mellitus to decrease the amount of glucose produced by the liver and to increase the body’s response to insulin. In patients with renal failure (acute or chronic), the renal clearance of metformin is decreased, and there is an associated risk of lactic acidosis, which has a mortality rate of up to 50%.1 Some patients who receive intravenous contrast may experience a deterioration of renal function (contrast-induced nephropathy). Although the points in this article discuss the use of intravenous contrast, the same principles apply to intra-arterial contrast. Go to: Use of metformin is not a contraindication to intravenous contrast administration Metformin in isolation is not considered a risk factor for contrast-induced nephropathy,2 but particular attention must be paid to patients taking metformin who are scheduled to undergo contrast-enhanced examination (e.g., enhanced computed tomography [CT], angiography, venography).3 Many physicians are particularly cautious in the case of elderly patients aged greater than 80 years. Go to: For most patients, metformin should be stopped at the time of contrast administration There is some controversy about when to stop and restart metformin for patients scheduled to undergo intravenous contrast-enhanced examinations.4 The guidelines from the Canadian Association of Radiologists2 state that patients taking metformin who have an estimated glomerular filtration rate (eGFR) of less than 60 mL/min should stop taking metformin at the time of contrast administration. The European Society of Urogenital Radiology advocates stopping metformin 48 hours before CT for patients with an eGFR of less than 45 mL/min.5 Go to: Restarting metformin depends on renal fu Continue reading >>
