Courageous Resolution Certificate Printable 2007-2025 Form

You are trying to compare three completely different technologies using a single parameter - resolution. Just because one modality has a better resolution does not mean it is better. Also resolution can mean either:Spatial resolution - what is the smallest points the modality can resolve between. andContrast resolution - how structures with different physical properties are differentiated.Temporal resolution - the ability to resolve moving objects.Also another factor to be taken is that all these modalities are constantly improving and thus one of them may be better than the other at a particular time, only for the other to make some improvement which will make it better.That being saidUltrasound: Use pulses of very high frequency sound. Probably the best spatial resolution of all the modalities. This is especially true when using very high frequency probes. The trade off with very high frequency probes is that they cannot see the deeper structures like the deep portions of liver or pancreas(although you could use a endocavitary probe to get very near to the pancreas). Also the sound waves cannot pass through bone and air - so presence of intestinal gas and air in lungs are a limiting factor. It also cannot visualised marrow abnormalities. Also it cannot image the adult brain. The body can be imaged in real time, allowing easy performance of image guided procedures. However the contrast resolution is poor.MRI: It uses differences in the water content of tissues to form images and has undoubtedly the best contrast resolution of all the modalities. Also no matter what the tissue is the MRI can see through - marrow abnormalities, deep structures such as pancreas can be well seen. It is especially good in visualising small amounts of fluid which are seen in ducts with great clarity due to the contrast resolution. As far as spatial resolution is concerned it is so-so. The higher the field strength of the main magnet, the better the spatial resolution. Now there is news about a 7tesla MRI scanner entering the market, which will be a game changer as far as spatial resolution is concerned and will likely give near microscope type images. Temporal resolution is fair.CT scan: Different density tissues absorb different amounts of x-rays the attenuated x-ray beams are measured in different angles and images are formed. The spatial resolution is excellent. The latest machines have a sub-millimiter resolution. Contrast resolution is so-so, and we have to give iodinated intravenous contrast to make structures stand out from the back ground. The newer machines are so fast that they allow us to image fast moving objects such as the heart - thus allowing examination of the blood vessels of the heart.In your specific question of how ultrasound compares with CT or MRI in visualisation of liver and pancreas abnormalities. It Does not compare. It is a highly operator specific modality - a good sonologist/radiologist can pick up most lesions. If the patient has a lot of gas, pancreas would be impossible to evaluate. So if money is not an issue you could get an MRI.

The very moment the CT scan is done, there will be no radiation in the CT scan room or in your body. So person who undergoes a CT scan or radiation therapy treatment is not radioactive(emitting radiation). He or she can mingle with their friends and family including kids.After certain procedures like bone scan, PET scan and radio-iodine treatment, where a radiotracer is injected or swallowed the person will be emitting minimal amount of radiation (from the radiotracer) for a limited period of time. In such cases they should have minimal contact with other people, especially babies. Your doctor will tell you how much time(varies between a few hours to couple of days), you should avoid close contact.

Just register on the admission portal and during registration you will get an option for the entrance based course. Just register there. There is no separate form for DU CIC.

You need at least 20 plus to get an A grade perhaps the rest of your class is around the 20 mark by plus or minus 1.So to be on the safe side, try and be the Topper always. If not first, second or third. Remember, your marks at the end or rather your GPA depends on the performance of the whole department as it is relatively graded.
