Renal Ct Scan With Contrast
Either: I usually do them without so I don't expose the patient to the contrast, which can injure kidneys. However, if the tumor is close to the mediastinum, I usually do order it with contrast because it's often difficult to tell the various structures apart without it. It also helps to identify lymph nodes. ...Read more
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's difference between High HD Contrast CT scan vs Normal Chest CT with contrast evaluating interstitial lung markings?
Different chest CTs: High resolution chest CT usually with out intravenous contrast is used to define interstitial lung disease pattern, whether diffuse or localized process. CT of chest examination with contrast intravenously usually looking for tumors or metastases and acute infection in the lungs. ...Read more
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
Not really!: The CT will show spasm or edema ( swelling of the bowel wall) but you need something such as endoscopic studies to rule out any inflammatory disease which is a serious health issue, unlike that of irritable bowel which is also painful but not progress in most cases. ...Read moreSee 1 more doctor answer
Sometime: Unfortunately the exam you mention only discloses larger tumors. A "Vitrual colonoscopy" is a more sensitive test. It involves a preparation of the bowel . The "gold standard" is, of course a colonoscopy by a Gastroenterologist, you are too young to require this on a "routine basis" Do you have symptoms???? Hope this helps Dr Z ...Read moreSee 2 more doctor answers
No contrast CT showed ill defined hypodense area on hepatic lobe. Ordered new CT w contrast w liver mass protocol not hemangioma protocol concerning?
Get iv contrast CT: There are many reasons to have a liver mass, more often than not, they are benign, but clearly depending on past medical history, It is difficult without contrast to differentiate these lesions, there are various ways to give intravenous contrast. A hemangioma protocol is also known as a triphasic study, allows one to look at three phases of liver perfusion but more complex to do. ...Read more
It should: Oral contrast and intravenous contrast is needed to evaluate if there's compensation of the liver. Ultrasound also can show blood flow direction to further help in evaluating the liver ...Read more
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
Whats better for diagnosing pancreatic cancer.... Ct scan or mri? I've had normal ultrasound and CT scan with contrast. Still worried.
No: Iv contrast is often not used when the ct is for the purpose of looking for renal stones and in people with a history of contrast allergy or renal disease. It is often helpful in assessing persons with nonspecific abdominal symptoms as it will better show areas of inflammation, infection, and tumor. ...Read moreSee 1 more doctor answer
Several things: Can be seen on ct scan. The oral contrast helps deliniate some of the intestinal findings. Other organs are also seen such as liver, pancreas, gallbladder, aorta, lymph nodes, kidneys, urinary bladder, uterus or prostate, vertebral column, etc. Some structures are seen better than others. ...Read moreSee 1 more doctor answer
Cyst fluid filled: Cysts are fluid filed, typically benign. Solid could be benign (not cancerous) or not. Small are typically benign. Ct may not be able to differentiate small solid abnormalities. Plan depend on other factors-may be monitor over time for stability. Cysts may not get followed. ...Read more
Yes, ...: Megacolon is suspected in patients with constipation of very long duration, abdominal bloating +/- pain, palpable fecal mass; this is chronic. At times, it can be acute & toxic. Imaging studies of CT scan with/without contrast + barium sulfate confirmed the diagnosis. For future events of health concern, follow the instruction in articles listed in http://www.formefirst.com/onDealSickness.html. ...Read more
Is there a lot of radiation associated with a CT scan with contrast for the renal area? Can the contrast cause an allergic reaction?
No: CT of abdomen is a fairly routine test and not considered a radiation danger. Th incidence of allergic reaction to contrast is 1-3% with non-ionic agents and 4-12% with ionic contrast agents.Non-contrast agents are the type generally used today. The benefit from the diagnostic value of the test far exceeds the risk of these 2 issues. Hope this answers your question. ...Read moreSee 1 more doctor answer
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.
I read in articles that the dye used for a contrast abdominal/renal CT scan can cause many severe side effects including renal damage/failure. True?
True: IV contrast can cause severe allergic reactions in some people, especially those allergic to iodine or shellfish. IV contrast is removed from the body by the kidneys. If one is dehydrated or has baseline kidney dysfunction, administration of contrast may worsen kidney function, leading to temporary or permanent kidney failure ...Read more
My grandad's CT scan (abdomen with contrast) results says renal cell carcinoma. Should i be worried about this? :/
What does it mean when a renal CT scan shows, thinning of the cortex, punctate calcification (with no stones), and contrast extending into the calyx.
Atrophy: Renal cortical thinning is seen due to functional loss of nephrons. There are many causes of "medical renal disease"which result in atrophy. Hypertension is the leading cause. Punctuate calcification s are very tiny stones. Contrast is supposed to be in the calyx, so i'm uncertain why that was stated. Was there anything else related to that statement? ...Read more
Just had a ct scan done with contrast it showed left adrenal adenoma 1.7 cm. small renal hypodensities left kidney. 1cmcomplex cyst left kidney should I be worried?
Likely no, but..: What you report are largely seen incidental findings but a few loose ends here should be addressed to make sure there is nothing more insidious ie.. how complex exactly is that left renal cyst? also, an adrenal adenoma cannot be definitely diagnosis on a contrast enhanced scan unless a very specific protocol was followed. Feel free to schedule a consult and we can review your CT and the details. ...Read more

Excretion is normal.: The kidneys excrete (produce, emit) urine under normal circumstances. When you have a CT scan, the contrast ('dye') you were given through your vein is excreted along with the urine from the blood stream. The 'dye' outlines your kidneys, ureters, and bladder (your 'plumbing') for the radiologist. to see. ...Read more
What does renal collecting systems are not appreciably dilated mean on a CT scan? Cause for concern?
Ct scan showed Tiny punctate left lower pole renal calyceal stones which measure 1 mm or less in size. What does it mean?
Pyelonephritis: Sounds more like a kidney/upper genitourinary infection rather than ureterolithiasis (“kidney stone”). check urinalysis for infection and treat with antibiotics if necessary. kidney stones may or may not ever cause problems until they pass into the ureter and cause obstruction. ...Read more
My ct scan showed Low-density renal lesions are noted. The smaller of these are too small to characterize. The
larger of them are cysts. No tumor . ?
The small: lesions are probably cysts as well, but you may need an ultrasound to confirm it. Talk to your doctor about the results. ...Read more
USS July diagnosed 3.8 CM simple L renal cyst. Renal CT scan yesterday showed 3cm exophytic mass arising from L upper pole looks like a cyst ?? CA
Tissue is the issue: Hi. Diagnosis of what the renal mass is requires tissue for the pathologist to examine. Imaging studies may be suggestive or not, but to be certain, a pathologist must study a CT- or U/S-guided core biopsy of the mass. Sometimes surgical biopsy is necessary to determine whether benign or malignant. We don't have the means to make that determination. The mass may not be suspicious enough to biopsy ...Read more
Ct scan false negative? 2012 renal US found 5mm solid lesion (likely aml). New US found bilateral lesions, avascular. 5mm now 7mm. New 1cm, CT normal
Renal cysts: Renal cysts are common in people over the age of 50, and are not significant. I don't know what AML stands for. A solid lesion needs a repeat study after a few months to show that it is not getting larger. You should review the CT report with your physician ...Read more
M58, CT scan says "bilateral renal cortical cyst noted. The largest cyst at the upper pole of the left kidney measures 3.8x5 cm." Is this significiant?
Probably not: The majority of people develop a few kidney cysts, especially by the time we reach your age. They are usually benign. A kidney ultrasound would better characterize if it is a simple cyst (benign) or not, especially if there was no IV contrast in the CT scan. It should be noted how many cysts were found, which was not apparent in your description, so I'm only assuming one on each kidney. ...Read more
CTA: CTA is noninvasive, the only issue is Kidney function, CTA need a decent dye load, if your kidney is stable post CTA, most patient can resume daily activity right away.This is based on the assumption, you only had a CTA and no intervention was done. If an intervention is done, you should D/W your MD. ...Read more
Which is better at evaluating complex renal cysts in children - CT scan or mri? Is the bosniak scale used in children?
Reasonable F/U...: Either one should be sufficient for evaluation after suspecting cystic lesion in kidneys of children, which can be categorized with bosniak system. After that, no further ct or MRI is needed but annual renal us in 1 yr for 1-2 times. If stable and asymptomatic with normal us, further study is usually unnecessary. Of course, beware of unwanted radiation to the children. ...Read more
History of renal stones, pain in right side. CT scan clear. Blood test results clear except for low magnesium 0.79mmol/L. What does it mean?
Magnesium: low magnesium has been associated with calcium oxalate kidney stones. Magnesium can inhibit the formation of calcium oxalate in the urine. It can also reduce blood calcium oxalate levels. It has been shown that taking oral magnesium and vitamin B6, an inhibitor of calcium oxalate metabolism can decrease the incidence of stones. See a kidney specialist for a stone work up. ...Read more
