What is a hyperdense renal  cyst on a non contrast CT scan?No contrast because creatinine 1.49.

Hyperdense cyst: On noncontrast CT scans, most simple kidney cysts look very dark or hypodense because the fluid inside of them is just like water. A hyperdense cyst looks much lighter or brighter compared to the kidney itself. This usually just means that there is high protein in the cyst or that the cyst has bled at some point. ...Read more

Computed Tomography (Definition)

Ct uses xrays taken an 360 degrees combined with a computer to see"inside" the body. The table moves as the xray tube and detectors spin around the patient 10 times a second or more! the image shows excellent soft tissue detail, enhanced with injection of intravenous contrast or oral contrast. This way the body is shown in slices, in any plane, usually axially, but ...Read more

What is a hyperdense renal cyst on a non-contrast CT scan? Contrast not give b.c. creatinine 1.49.

Protein: Hyperdense cysts can be associated with higher amounts of protein which will increase density. Sometimes these cysts may have a little blood or fibrin that may increase density. Calcium in the wall of the cyst is easily seen and different from the other things ...Read more

Good morning. I recently had a CT scan performed. As part of the preliminary test, they did a creatinine screen. My level was 1.24 and egfr of > 60.

Good morning.  I recently had a CT scan performed. As part of the preliminary test, they did a creatinine screen.  My level was 1.24 and egfr of > 60.

Good for you: I am a pathologist and lab specialist. Serum creatinine has a lot to do with muscle mass. When I was lifting weights every day, mine ran 1.6 to 1.8. The GFR's estimated from spot creatinines are subscience and even include a racial adjustment "because black people are more muscular." It is bogus. Be grateful for good health. ...Read more

4 days after contrast CT scan blood free Ca was I. 1,35 mmol K was in 5,7 sodium in 143 mmol cretinine and mg were normal can this be the contrast?

4 days after contrast CT scan blood free  Ca was I. 1,35 mmol K was  in 5,7  sodium in 143 mmol cretinine and mg were normal can this be the contrast?

Ca/k: From your labs it looks like you were a bit dehydrated as your sodium was 143. I would hydrate and repeat it if you are worrried in a few days. Don't worry Good luck ...Read more

BUN 13, creat 1.19 GFR 50. Is it safe to have a CAT scan w/ contrast?

BUN 13, creat 1.19 GFR 50. Is it safe to have a CAT scan w/ contrast?

Yes: This is basically a normal creatinine especially if you are a solid-built lady. When I was working out every day, my creatinine ran 1.6 or 1.7. The GRF 's estimated are subscientific -- there is an adjustment for race "because black people are more muscular." You are not a kidney patient unless there is something else. Best wishes. ...Read more

Mild kidney CRI: Your numbers indicate mild chronic renal insufficiency & or decreased kidney functions. If you have cyst less than 5 cm - it is not worrisome . Any cyst close to 5 cm should by monitored periodically by ultrasound.,At best consult Nephrologist - especially if u have some significant family history.,Avoid nephrotoxic drugs as much Ibuprofen ( NSAID's) . ...Read more

Collar bone pain, swelling. X-ray, CT scan nl. Labs for sed rate, cpk, creatinine kinase, CBC all nl. Pcp, pain dr stumped. Any ideas or suggestions?

Collar bone pain, swelling. X-ray, CT scan nl. Labs for sed rate, cpk, creatinine kinase, CBC  all nl. Pcp, pain dr stumped. Any ideas or suggestions?

Do you lift weights?: If you lift weights (benchpress), that might be the culprit. The muscles and ligaments that attach to the collarbone are shown in the diagram. If your pain is at one of these places, you likely have a strain from lifting. If you've fallen on your outstretched arm, the same thing can happen. Also, ask your doctor about osteonecrosis (dying bone due to lack of blood supply). Hope that helps! ...Read more

Can high calcium and potassium in blood taken 4 days after contrast CT scan be caused by the contrast? Normal creatine and urine test

Can high calcium and potassium in blood taken  4 days after contrast CT scan be caused by the contrast? Normal  creatine and urine test

Yes: Newer contrast today withnon-ionic iodonated contrast has less potential for side effects compared to the older generation of contrast. However, contrast-induced nephropathy can occur within anywhere from 1-5 days, with incidence of 0-40% depending on your risk factors, such as pre-existing diabetes, metformin usage. Potassium and calcium levels can increase due to decreased kidney function. ...Read more

Could a CT scan with contrast affect a estrogen test the following day? Could it cause it to be low

Could a CT scan with contrast affect a estrogen test the following day? Could it cause it to be low

Not likely: Estrogen levels fluctuate depending on where you are in your menstrual cycle. If your estrogen was very low (in the menopausal range) your fsh level should generally be high. If your fsh was not checked, or it was checked and was nomal, i would just consider asking to have your estrogen level retested. ...Read more

Ct Scan (Definition)

Ct scan uses data from a beam of xrays and reconstructs a cross sectional image of your body. It is a high dose of xrays and used only when the benefits outweigh the risk. Cancer risk is 1 in 500 in children. Also using iodinated contrast might cause transient renal failure in about 5% of patients. (contrast induced nepropathy) most do not explain this to the patient as ...Read more
