Mri or magnetic resonance imaging is one of the more recently developed imaging modalities available to physicians. It uses powerful magnets to generate images. There is no ionizing radiation which is a major advantage over many other modalities. Mri is the best imaging exam that we have for most soft tissue and joint related problems. There are radiologists ...Read more

Due to kidney stones I have had 2 ultrasounds, 2 ct's and 1 MRI w/contrast in past year. If I had pancreatic cancer would one of these picked it up?

Whether the: CTs or MRI you had would be sensitive in detecting a small pancreatic cancer would depend on the technical parameters of the scans, so without additional information it is difficult to say. Large tumors would not be missed, small tumors might not be detectable if the scan was tailored for other purposes. ...Read more

Should I contact a different doctor for adrenal mass went to a urologist after a CT scan for kidney stones showed an adrenal mass. Urologist sent me for a MRI and had me do a 24 hour urine test to see why I had kidney stones. I am more worried about the

The most common: Adrenal mass seen in about 15% of patients is an adrenal adenoma which is a benign tumor. It is easy to characterize on MRI because we can show there is fat in the tumor. This usually (94% accurate) means that the adrenal tumor is benign. But we make sure by following the tumor with additional MRI studies, which do not use harmful radiation. Ultrasound is not as accurate for followup. ...Read more

Can a ultrasound show a kidney stone blockage thanks?

Can a ultrasound show a kidney stone blockage thanks?

Yes, depends on seve: If the blockage is complete & urine backs up into the kidneys, you can get a condition called hydronephrosis. This can be detected on ultrasound due to the dilation of the ducts in the kidneys (like stepping on a garden hose- water backs up & bulges). Ultrasound can miss a kidney stone due to its location or size; however, it can detect the *effects* of a kidney stone, by which diagnosis is made. ...Read more

I recently had an lumber spine X-ray if I've got kidney stones will they show on this x-ray?

Kidney Stones: A plain x-ray will only see kidney stones that have partially calcified; not all kidney stones, however, have calcium in them, so if you have typical symptoms - excruciating pain radiating into the groin, for example - you may well have a stone that is not calcified. Other tests can determine if you do. Follow up with your urologist. ...Read more

Kidney stone: A kidney stone in the ureter may be seen on a plain film, but other radiographic modalities are better such as an IVP, CT scan, or ultrasound. You may have some blood in the urine as the stone passes through the urethral system. If you still have pain and have not passed the stone, follow up with your doc, as you may need lithotripsy or some procedure to break up the stone and allow it to pass. ...Read more

I have kidney stones of 3.4 n 3.8mm. In 1st urine test albumin is +, and after 10 days again it show albumin is traced... Is it normal or any serious?

Here are some...: Most likely, the trace- (+) finding of albumin is not clinically significant, i.e., not serious, but annual urinalysis for next 3-5 yrs as follow-ups for comparison is reasonable. As to the kidney stone of 3.4x3.8 mm, you may leave it alone as long as not bothering you since the odd to pass a stone of this size is high. More?

Does a CT or ultrasound always show kidney stones?

Does a CT or ultrasound always show kidney stones?

No: Ct and ultrasound does not "always" show kidney stones. The resolution may not be sensitive enough to see very small stones less than 2 to 3 mm. Depending on the thickness of the images on the ct scan, a stone may be potentially missed between the images taken by the ct scanner. Ultrasound may also over-read or miss very small stones as well. Overall though, the detection rate is still very hi. ...Read more

What's the best way to detect kidney stone? I had hematuria RBC of 20-23 in my urine. But my uzd shows normal.

Ct scan: Ct scan is the best, most sensitive test. Plain xrays detect most stones since they have calcium. Ultrasound detects most large stones but may miss small stones. High def ultrasound is good also. The radiation exposure with a ct can be decreased by performing a stone study and evaluating only the kidney, reuters and bladder. ...Read more

I have consistent kidney stones weekly/monthly but every time I go for a CT they don't show up, what is going on?

CT Stone Protocol: Some ct scans that are done, if not calibrated for thin cuts, may miss symptomatic stones. However, if you are having recurrent symptoms without any proven stones, then i'd look for other answers. Ct, done properly, is about 99% sensitive for stone. The only stones that don't show up on ct are Crixivan (indinavir) stones. If you take that medication, let your doctor know. If not, it's likely not stones. ...Read more

If I had a CT scan without contrast would kidney stones show up. ..

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
