Cat Scan Of Kidneys
Not sure: Ct with and without xray dye is a good test for some kidney problems. Not sure what you mean by thickening. Ct shows kidney stones, masses, kidney size/location ; can give a good idea of whether the kidneys are working well. Ct is also good at showing the site of blockage of urine flow, when present. ...Read more
The kidneys are paired organs that lie on either side of the vertebral column. Part of their critical functions include the excretion of urine and removal of nitrogenous wastes products from the blood. They regulate acid-base, electrolyte, fluid balance and blood pressure. Through hormonal signals, the kidneys control the ...Read more
Solid/hollow organs: Barium outlines GI tract; IV contrast helps outline solid organs. Expect to get views of stomach, duodenum, small bowel, colon, rectum; liver, spleen, , gall bladder/bile ducts, pancreas, adrenals, kidneys, ureters, bladder, prostate or uterus, tubes, ovaries, vagina, lymph nodes, arteries, veins, assorted muscles. Generally get a view of diaphragm, lower lungs, pleura, spine, pelvis. More stuff. ...Read moreSee 1 more doctor answer
Not quite: The CT of the sinuses focuses in on the sinuses (though the radiation goes through the entire skull) and generally covers the entire set of sinuses (sphenoid, maxillary, frontal, ethmoid). The orbital CT will cover the eye sockets (and those pictures are zoomed in). While the sinuses lies behind the eyes (& so they overlap), the focus & coverage of these scans are slightly different. ...Read moreSee 1 more doctor answer
Possible : The IV contrast provides imaging of blood flow into kidneys and will detect blockages, aneurysms, asymmetric flow, mass, structural problems. Lab draw and renal panel provide functional information on how your kidneys are performing as filters. Your doc will want to follow up with you after all the studies are complete to give you results. The IV contrast itself can be damaging to your kidney. ...Read moreSee 1 more doctor answer
I've undergone ultrasound, renal scan and CT scan. The CT scan results was 1. There is no lithiasis of hydronephrosis 2. No perirenal or periureteral.
High sensitivity: The sensitivity of CT scans in detecting small renal masses is greater than 90%. The CT scan should be tailored specifically for this purpose, utilizing thin slices and intravenous contrast injection. If the CT scan was performed without IV contrast, and without thin sections through the kidneys, sensitivity declines. ...Read more
No.: The nephrotoxic effect of contrast is dose related, and does not accumulate over time. Multiple CTs would only make a difference if you had them within a very short time frame, for example if you had several contrast enhanced scans on the same day or over the course of a few days. ...Read more
Urologist ordered CAT bc blood in urine and an earlier ultrasound that showed 4 kidney stones. What body parts will show up in the CAT scan?
Abdomen and pelvis: The CT scan ordered when a patient has blood in the urine is of the abdomen and pelvis. It will show the kidneys, ureters, bladder and will also incidentally show the liver, lower lobes of lungs and spleen. Normally contrast is given intravenously when checking on urinary bleeding. Best wishes. ...Read moreSee 1 more doctor answer
Would a CT scan on the abdomen without contrast show kidney stones or gallbladder inflammation better than ultrasound?
CT for stones: Ct without contrast is much better than us for kidney and ureter stones. Ct detects calcium better. Most gallbladder disease involves inflammation. Us is better for right upper quadrant pain and suspected gallbladder disease. It is also cheaper and involves no radiation, so it is arguably safer over a person's lifetime. ...Read moreSee 1 more doctor answer
A CAT scan: With contrast provides 3d slices of all of the organs, today every 3mm, and these can be reconstructed to provide coronal (front to back) and saggital (right to left from the side) views. These were developed 40 years ago and incredibly changed medicine. ...Read more
Wrong: Ct scanning of the abdomen and pelvis shows the colon, yes, but not subtle mucosal lesions such as early cancer. It shows your internal organs such as the liver, spleen, kidneys and pancreas in great detail. It also shows your small intestinal and the numerous blood vessels. It can evaluate the connective tissue and fat to uncover inflammatory conditions or infections. ...Read more
Need contrast: Very difficult to see aneurysms in the brain without contrast. If you are concerned about this as a possibility you should ask your doctor about your risk. ...Read more
