There are a multitude of questions asked by patients and caregivers every single day. Many of the topics I could not begin to explain, and many others aren't really appropriate for this forum. Some of the following questions are asked most frequently and I hope they will help you too.
What will a CT of the brain show?
A CAT scan of the brain, or head, will show a number of things. It will demonstrate a number of vascular problems, ie..strokes, cerebral hemmorrage, or an abnormality of vessels that you could have been born with. It can identify masses or tumors, foreign bodies, or fractures of the skull. In some cases fractures or abnormalities of the facial bones are demonstrated. If there is fluid within the sinuses it will be seen as well.
What is a Renal Stone Ct?
This is a CAT scan specifically looking for a kidney store/ & or a subsequent blockage of the kidneys. There is no need for any contrast or dye so it is a Non-invasive type test. Kidney stones will most often show and if there is any blocking of the kidneys (hydronephrosis)
Will a CT show appendicitis?
Many times a CAT scan will show the inflamed appendix (appendicitis). The idea test is an Abdomen/Pelvic CT with contrast. Sometimes the physician will ask for Oral contrast to coat the stomach and intestines and also an IV contrast. This contrast is given through a vein, and it will demonstrate the urinary system. It also helps to enhance vessels around inflamed areas. The appendix may appear enlarged, have thickened walls, or sometimes it may have a calcification inside it called an appendicolith. Occasionally the appendix may not be clearly seen but there will much edema or swelling around the area. This is often a signal of appendicitis. The physician will consult lab results, a clinical evaluation, and often the CT scan before he makes the decision to do surgery.According to the New England Journal of Medicine in 100 consecutive cases of suspected appendicitis Ct scans prevented 13 cases of UN necessary surgery.
