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

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

Confused . Mcrc patient . Old CT scan says no lung lesions . New CT report 4 months after .. "Another upper lobe nodule which remains unchanged "?

Confused . Mcrc patient . Old CT scan says no lung lesions . New CT report 4 months after .. "Another upper lobe nodule which remains unchanged "?

The nodule: may not have been commented on in the first scan, but it was noticed in the second CT. When the interpreting radiologist saw the nodule, he probably reviewed the old one and found it there too. A stable nodule is often a good thing in the right context. Talk to your doctor with any questions. ...Read more

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

Old CT reports .. No lung lesions . New CT reports ..... Upper lobe nodule remains unchanged . Mcrc patient . Confussed plz advise ?

Old CT reports .. No lung lesions . 
New CT reports ..... Upper lobe nodule remains unchanged .

Mcrc patient . Confussed plz advise  ?

Missed nodule?: It is possible that the nodule was so small that it was missed on the first CT report. Whenever you have a CT scan or xray the radiologists always looks back and the previous one for comparison. It is possible that the radiologist that read the more recent CT saw something that was missed earlier. The fact that it is unchanged between CT reports means it is probably benign. ...Read more

Non contrast CT scan show growing brain tumor, what is wrong?

Non contrast CT scan show growing brain tumor, what is wrong?

Need more evaluation: It is very difficult to diagnose a brain tumor on a non-contrast ct scan. I would recommend getting a brain MRI with contrast (called gadolinium). Mri takes a much better look at the brain than does ct. ...Read more

Are CT Scans accurate at discovering cancer?

Are CT Scans accurate at discovering cancer?

So-so: It depends where, how big the cancer is, and so forth. The new CT scans pick up lung cancers that are quite small -- most of the "cures" of tumors found this way may be of non-aggressive tumors. A scan can pick up a mass suspicious for cancer but of course tissue's required for certainty. ...Read more

How accurate are contrast cat scan in detecting non ruptured annreuysms brain?

How accurate are contrast cat scan in detecting non ruptured annreuysms brain?

Aneurysms: Compared with the number of aneurysms detected on dsa, the overall accuracy rates of cta and mra for aneurysm detection were 89% and 90%, respectively. 4 the sensitivity for aneurysms 3 mm was 96% for cta and 94% for mra. ...Read more

Which type of CT scan required for detecting metastatic clear cell renal cancer in chest/abdomen, is it plain or contrast ?

Which type of CT scan required for detecting metastatic clear cell renal cancer in chest/abdomen, is it plain or contrast ?

This sounds like: Radiology calling. It should be the radiologist deciding, but the contrast tends to identify vessels, and some tumors "flush" with contrast. The contrast is iodine based. One wants to see vessels in venous phase in a kidney tumor, and looking for metastasis to liver and lung. I vote for contrast. ...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

Is Full body PET scan or CT scan better for diagnosing Lymphoma? Which uses less radiation?

Is Full body PET scan or CT scan better for diagnosing Lymphoma? Which uses less radiation?

Both: The actual diagnosis of lymphoma requires tissue, usually excisional biopsy of an entire lymph node. Staging to see where other sites of disease could be is done with a combined PET/CT. The staging used to matter more many years ago when they would often give XRT or do surgery, it doesn't matter as much as it used to because almost everybody gets systemic chemotherapy for both Hodkins and non H ...Read more

Whats better for diagnosing pancreatic cancer.... Ct scan or mri? I've had normal ultrasound and CT scan with contrast. Still worried.

Whats better for diagnosing pancreatic cancer.... Ct scan or mri? I've had normal ultrasound and CT scan with contrast. Still worried.

Why worried?: Why are you worried? Do you have symptoms or abnormal labs? If the ct was normal and used a specific pancreas protocol, then an MRI of the pan creas may be the best next test. Since it does not use radiation, there is little risk for you. ...Read more

Post op seminoma, in r testicle. Pet scan done for suspecious nodes. Pet scan result shows negative for any abnormalility. This means no seminoma?

Post op seminoma, in r testicle.  Pet scan done for suspecious nodes. Pet scan result shows negative for any abnormalility. This means no seminoma?

Surveillance: A negative pet scan means there is no accumulation of cancer cells large enough to be discernible by the pet scanner. There is a resolution limit of about 7mm in size to be seen, some are better now. I am not trying to scare you, but your doctor i'm sure will continue to caution you and continue surveillance for a period of time safe to say you are cancer-free. ...Read more

Which modality is better for detecting or confirming metastasis pet scan or bone scan? !

Which modality is better for detecting or confirming metastasis pet scan or bone scan? !

Depends on cancer: Each cancer type has an optimum way to image it, especially with techniques that image physiology, like pet and bone scan, as opposed to techniques that image anatomy, like ct and mri. Pet is best for cancers that use a lot of glucose as an energy source, like lung cancer. Bone scans are best for cancers that disrupt bone, like prostate cancer. ...Read more

Hx breast ca, US spleen meaning?: Multiple hyperechoic solid lesions, indeterminate nature. Hemangiomata possible but metastatic disease not excluded.

Hx breast ca, US spleen meaning?: Multiple hyperechoic solid lesions, indeterminate nature. Hemangiomata possible but metastatic disease not excluded.

Your doc can explain: Your spleen has some shadows which require better imaging than what the Ultrasound produced. Your doctor should guide you further because it will take a CT scan or MRI test/s to provide a more clear picture of what the nature of these shadows in your spleen is. ...Read more
