Bun And Creatinine Test After Contrast Ct Scan
Would a CT scan show gallstones because my CT scan came back clear. Also, would a CT scan combined with urine tests and blood tests detect gallstones?
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
Sodium low&cortisol highi& fatigue&weight loss. Clear CT scan in Apr15. Symptoms persisted CT scan in Feb 16 clear. Could CT missed SCLC. Repeat scan?
Look outside lung: Yes CT scans can miss SCLC, especially if the scan is not a 'high resolution' scan with sufficient overlap. However, with 2 negative scans, you should look outside the lung. Head & neck cancers and esthesioneuroblastoma (tumor of nerves that sense smell) can cause this symptom pattern. Though rarer, SCLC can occur outside the lung, as well. A PET scan or whole body bone scan could help. TTYD. ...Read more
Whats better for diagnosing pancreatic cancer.... Ct scan or mri? I've had normal ultrasound and CT scan with contrast. Still worried.
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 moreSee 1 more doctor answer
Whats better for diagnosing pancreatic cancer? Ct scan or mri? 34yr male. I've had normal ultrasound and CT scan with contrast. Still worried.
CT, ERCP, MRCP: Thin-slice (3 mm) ct abdomen yields fine detail of pancreatic structures... Blood tests including tumor markers: ca-19-9, ca-15-3, and cea can alert the clinician for ca. Also, ERCP w/ ductal brushings (though its endoscopy) can search for malignancy. Finally, mrcp may add to the clinical picture, but 64-bit ct is slowly encroaching on the former's superiority. ...Read more
Urine amylase slight elevated (0-17) 25, regular serum amylase. Normal mrcp, CT scan, ultrasound. Any reason why urine elevated and not serum?
Trace hematuria, and proteinuria on some ua dipstick. Blood work shows normal kidney function. Ct w/contrast, xray kub, and us all normal. Ideas?
Benign glomerular dz: Hematuria and proteinuria suggests a glomerular cause ( kidney filter) since the urologic studies are negative. Kidney biopsy would be diagnostic but makes no sense since risk of progressive renal failure is very low as long as the urine protein is less than 500 mg a day. Diagnosis would include IgA nephropathy, thin basement membrane disease among others. As long as normal function u r ok. ...Read more
Are normal cbc, billuprin, amylase and lipase levels, CT scan and qualitative fecal fat test a good indication against pancreatic cancer?
Trace hematuria, and proteinuria on some ua. Blood work shows normal kidney function. Ct w/contrast, xray kub, and us all normal. Ideas?
I bet you're fine: I don't believe in even working up trace proteinuria. Even visible hematuria with otherwise normal labs and imaging isn't a cause for alarm; one person in maybe 100 has thin-gbm non-disease and except for slightly poorer hearing than the next person, these folks are otherwise normal. ...Read more

Why gastronoligist sending me for CT scan again for pain in lower right stomach when had CT ultrasound blood urine and feacal calprotectin tests norm?
Cholestasis: I'm going to trust this is bilirubin and not just urobilinogen. It would surprise me if this was from your plaquenil (hydroxychloroquine). If your serum conjugated bilirubin is normal, then there is a lab error. If you feel well, other labs are good, and you're not on some other troublesome Rx, this might be something to simply follow. ...Read more
Endocrine issues + fatigue. Clear CT scan in Apr15. Symptoms persisted CT scan in Feb 16 clear. Could CT be missing SCLC. Is repeat scan necessary?
By SCLC, I presume: you mean small cell lung cancer...a type of lung cancer that is aggressive and is a neuroendocrine tumor which can produce ectopic hormones. But it certainly wouldn't be the first thing you would think of if you have "endocrine issues." The thyroid, pituitary, adrenal glands need full evaluation as well as other work-up. If lung CT "clear" would not pursue SCLC as cause. Best wishes:) ...Read more
Yes: In fact, ct scanning without contrast is becoming the gold standard evaluation for kidney stones. Contrast material frequently obscures stones and makes their identification difficult. Stones as small as 1 mm can be detected with unenhanced ct technique. Radiolucent stones which cannot be seen well with plain x-ray technique do show up well with unenhanced ct scan. ...Read more
