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

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? No contrast because creatinine 1.49.

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

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

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

What causes enlarged liver (20.5cm) with normal LFTs? Only abnormal labs in ER were low creatinine (0.5) and low BUN (5). No masses on CT. 24yo, BMI 25, no etoh. What should I ask my dr next week?

What causes enlarged liver (20.5cm) with normal LFTs? Only abnormal labs in ER were low creatinine (0.5) and low BUN (5). No masses on CT. 24yo, BMI 25, no etoh. What should I ask my dr next week?

Enlarged liver: As a start, someone needs to reevaluate that test and determine what portion of the liver was measured. 20 cm at the midclavicular line is large, but it is not in other planes. In the US, the most likely reason would be fatty liver, which is supported by the BMI of 25, which the NIH would say is overweight, but you need to be evaluated by a hepatologist to be sure nothing else is missed. ...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 dects brain aneurysms? Is it possible for a CT scan without contrast to reveal an unruptured brain aneurysm? Is the test meant to find that sort of thing?

Ct scan dects brain aneurysms? Is it possible for a CT scan without contrast to reveal an unruptured brain aneurysm? Is the test meant to find that sort of thing?

NOT THE BEST WAY: Mri with contrast will pickup most large aneurysms over the blood vessels of the brain, and a cat angio or a magnetic resonance angio would be used to find smaller aneurysms. Standard cat not usually successful. ...Read more

Dear wants to check for plaque in heart. He's doing a cardiac ct scan with contrast. Is this a good test for this?

Dear wants to check for plaque in heart. He's doing a cardiac ct scan with contrast. Is this a good test for this?

Yes: The cardiac CT is a very accurate test for seeing any plaque (cholesterol buildup) in the heart. It is more sensitive than an angiogram at seeing early blockages. It is more sensitive than a nuclear stress test, stress echo, or treadmill stress test.

My doctor wants me to get a CT scan with contrast to see if I have the varicella-zoster virus in spinal fluid;. Expensive. Is this only way to test?

No: Well! ct scan is really an indirect and non invasive way. The direct but invasive way (and also a lot inexpensive) would be to do LP and send for viral cultures. ...Read more

Doc says ibs. I have had mre small bowel, CT scan with vein contrast, colonoscopy, blood tests. All were normal. What are the chances I have crohns?

Very low: If all the above were normal including colonoscopy and colon biopsies then your chances of having crohn's is very slim. New evidence points to fructose and high fructose corn syrup as the culprit in ibs. Try to avoid the for few weeks and see. ...Read more
