Virtual colonoscopy (http://www.laendo.net/educational-articles/english-educational-articles/143-virtual-colonoscopy.html) is essentially an x-ray examination using CT scan. Using a computer X-ray image creates an image of colon and any lesion that may be associated with the colon. It usually can detect problem that is larger than 1cm. Additionally, flat lesion are difficult to detect. Moreover, there may an additional risk of ionizing radiation that may predispose one to undesired risk of developing cancer later on. Finally, if a lesion is found, one would still have to undergo colonoscopy to either take a close look, take a sample or remove the lesion. As a result, despite conceptual appeal, virtual colonoscopy is not frequently utilized.
If you are referring to a Capsule Endoscopy which is a procedure where you swallow a small camera (pill) and pictures of your intestinal tract are recorded every 15 seconds then reviewed by doctors the next day, then YES it is a very useful tool and a definite advance in the arsenal of medical devices used to diagnose Intestinal disease.

How do virtual business simulations compare to traditional classroom training methods in terms of effectiveness and cost efficiency?
Virtual business simulations and traditional classroom training methods have distinct differences in terms of effectiveness and cost efficiency. While both approaches have their merits, virtual business simulations offer several advantages over traditional classroom training methods, particularly when it comes to skill-building and cost efficiency. One of the primary advantages of virtual business simulations over traditional classroom training methods is that they offer a highly engaging, interactive, and immersive learning experience. These simulations provide a safe and controlled environment for employees to practise and refine their skills, allowing them to experience and learn from real-world scenarios without the risk of costly mistakes. In contrast, traditional classroom training methods are often less engaging and rely on lectures, which may not be as effective in terms of skill-building. Virtual business simulations also offer cost efficiency benefits. Traditional classroom training methods can be expensive, particularly when it comes to travel, lodging, and venue costs. These costs can be significantly reduced with virtual business simulations, as they can be accessed from anywhere with an internet connection. Additionally, virtual business simulations can be customised and delivered to employees on demand, reducing the need for costly and time-consuming training sessions. MDA Training is a leading provider of corporate training solutions, and they offer both virtual business simulations and traditional classroom training methods. MDA Training's experienced trainers can work with organisations to determine which approach is best suited for their specific needs, taking into account factors such as the organisation's industry, the specific skills to be developed, and the available resources. MDA Training's virtual business simulations offer a range of benefits, including increased engagement, improved learning outcomes, and cost efficiency. MDA Training's experienced trainers can help organisations to design and implement customised virtual business simulations that are tailored to meet their specific needs, ensuring that employees receive the most effective training possible. In conclusion, while traditional classroom training methods have their merits, virtual business simulations offer distinct advantages in terms of effectiveness and cost efficiency.

What does physical address mean?
The physical address is the final address that is presented to the bus, at the pins of the microprocessor chip, to form the address of the desired item in memory.In the 8085, physical and effective addresses are one and the same.In the 8086/8088, the physical address is the effective address plus 16 times one of the segment registers.In higher level processors, such as the 80386 and beyond, the physical address is formed by lookup of the effective address in a page table to convert from virtual/effective address to physical, or linear, address.The effective/virtual address is the address generated by the instruction and the programmer, without regard to any underlying addressing scheme. This is the address used when considering the "programming model", in "user mode".

Virtual colonoscopy?
DefinitionVirtual colonoscopy (VC) combinesMRIorCTscans with sophisticated computer software to produce three-dimensional images of the colon and rectum. The test is less invasive than conventionalcolonoscopy. Alternative NamesColonoscopy - virtual; CT colonographyHow the test is performedPatients must follow a strict bowel-emptying procedure the day before, just as they would for a standard colonoscopy. The test is performed in the radiology department of a hospital or medical center. Unlike conventional colonoscopy, no sedatives are needed and no scope is used.You will lie down on your left side on a narrow table that is connected to an MRI or CT machine. Your knees will be up toward your chest. A small, flexible tube will be inserted into your rectum. Air is pumped through the tube to make the colon bigger and easier to see. After this is done, you'll be asked to lie on your back.Next, the table slides into a large tunnel through the machine, where x-rays create images of your colon. You must stay very still during this procedure, since movement can blur the pictures. You may be asked to hold your breath briefly while each picture is taken.A computer combines all the images to form three-dimensional pictures of the colon, which are viewed on a video monitor.Pictures are also taken while you lie on your stomach.The exam takes about 20 minutes.How to prepare for the testPreparations can vary, depending on your health care provider. Everyone undergoing any type of colonoscopy must completely empty their bowels before the exam. This may be done using an enema or laxatives combined with a liquid diet the day before the test. The bowel must be completely emptied until no solid matter remains.Unfortunately, diarrhea is common during preparation. Drink plenty of clear liquids, such as apple juice and chicken broth, to avoid dehydration.Make sure you tell your health care provider about any medications you are taking. You'll be told which you can take, and which you should temporarily stop. CT and MRI scanners are very sensitive to metals. Don't wear jewelry the day of your exam. You'll be asked to wear a hospital gown for the procedure.How the test will feelThe x-rays are painless. Pumping air into the colon can create temporary cramping or gas pains.Why the test is performedVirtual colonoscopy may be performed to:Diagnose colorectal cancerExamine those with a family history of colon cancerFollow up after an incomplete or failed colonoscopyFollow up after a previous finding of colon cancer or polypsLook for polypsNormal ValuesNormal findings are images of a healthy intestinal tract.What abnormal results meanPolypsColorectal cancerDiverticulosisLower gastrointestinal (GI) bleedingTumorInflammatory bowel diseaseWhat the risks areRadiation exposureThe medications to prepare for the test can cause nausea, vomiting, bloating, or rectal irritation.Special considerationsDifferences between virtual and conventional colonoscopy include:Both procedures can spot polyps that have reached a large, worrisome size. However, virtual colonoscopy is not as detailed as a conventional colonoscopy, and may miss polyps smaller than 10 millimeters in diameter or flat lesions.If a polyp is found with virtual colonoscopy, the patient must have a conventional colonoscopy to remove the abnormality. Conventional colonoscopy allows for the immediate removal of polyps.Virtual colonoscopy can view the colon from many different angles. This is not easy with conventional colonoscopy.Virtual colonoscopy uses no sedation, and patients are usually able to resume normal activities immediately after the test. Conventional colonoscopy involves sedation, and usually the loss of a work day.Virtual colonoscopy is now one of the American Cancer Society's recommended screening tools for colon cancer.ReferencesLieberman, D.
