How Do You Differentiate Between Tumor Or Clot On A Ct Scan
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

MOHS Surgery: Mohs surgery has come to be accepted as the single most effective technique for removing basal cell carcinoma and squamous cell carcinoma (bccs and sccs), the two most common skin cancers. It accomplishes the nifty trick of sparing the greatest amount of healthy tissue while also most completely expunging cancer cells; cure rates for bcc and scc are an unparalleled 98 percent or higher. ...Read more
Biopsy: "sigmoid colon, well differentiated adenocarcinoma, grade i" does this indicate that the tumor won't probably metastasize? Triphasic CT shows a lesion in the liver (1cm) as well.
May be benign tumor: PET scan shows the degree of metabolic activity and the CT shows the dimensions of the lesion that is producing metabolic activity(or lacking it.). Increased metabolic activity is a common feature of cancer as well as Inflammation. If there is no increased uptake of PET material(that means it is hypometabolic, as opposed to hypermetabolic, the lesion/tumor is unlikely to be Cancer(with a few exe ...Read moreSee 1 more doctor answer
Not ALL....: No ct scan (or mri, which is better for this) can detect everything. The results of any scan have to be put in the context of the symptoms that led to it being ordered. You doc will go over its findings with you and decide if you need additional tests. That being said, a good ct with contrast should see a good percentage of brain lesions. Best to you. ...Read moreSee 1 more doctor answer
Some variations in M: Mesothelioma can produce different kind of shadows in different people. Sometimes it is a single mass which is very easy to see. Most often it is a Diffuse thickening on the pleural surface of the lung. In such cases the tumor-shadows have to be near about 1cm or larger before the tumors are clearly visible requiring a biopsy for diagnosis. Most of these tumors produce chest pain as an early sympt ...Read more
Ct scan, said 10mm stone had lipo, xray not sure if its gone. Is it obvi on CT scan stone vs tumor? Uncert results making me nervous
CT is better: Bobcat: a ct scan is better than a regular xray to see smaller stones. The problem comes in when you already had a ct because we don't want to continuously expose you to the radiation of a ct scan. A sonogram might be a good option for you because it will show the kidney and whether there is any obstruction caused by the stone. ...Read moreSee 1 more doctor answer
Only at certain time: Bulky lesions in the retroperitoneum or masses growing off the bowel are frequently visualized. The same holds true for metastatic lesions to liver and lung. When we work up a patient for extensive surgical resection and want to be sure no metastatic focus is present to be addressed or might obviate the surgical procedure, a PET/CAT scan is employed where any malignant lesion lights up. ...Read more
It's possible: Ct scans are a great first step in evaluating the brain. However, they are not infallible. All tumors start as small lesions and can be missed at a very small size on ct scans. Often, a ct scan will show the brain's reaction to a tumor rather than the tumor itself. If there is little or no reaction, the tumor can be even harder to detect. ...Read more
When having a pet scan, is the CT scan that used in conjunction good enough to diagnose all tumors?
Good but not all: It is good to have ct in conjunction with pet scan because ct provides more resolution. It helps the radiologist correlate signals seen on pet scan with actual anatomy precisely. However, no test is perfect, so pet/ct is not able to diagnose all tumors. But pet/ct can diagnose many types. ...Read moreSee 2 more doctor answers
How small are intracranial tumors that don't show some kind of effect on a CT scan. If they are small would they be low grade/benign?
Hard to say: Many tumors even of moderate size can be somewhat difficult to see on a noncontrast ct scan. Would not necessarily be low grade or benign. If there are multiple actual tumors in the brain, the most likely diagnosis is metastatic disease from another tumor. An MRI with contrast should be obtained. ...Read more
Maybe: L'hermitte-Duclos disease is a very condition that is not cancerous by itself. Since the majority involve the cerebellum, that is not a strong point for CT imaging because of the bones. They get in the way. Under certain conditions it may be visible. MRI is now a days the way to go. ...Read more
Ct scan uses data from a beam of xrays and reconstructs a cross sectional image of your body. It is a high dose of xrays and used only when the benefits outweigh the risk. Cancer risk is 1 in 500 in children. Also using iodinated contrast might cause transient renal failure in about 5% of patients. (contrast induced nepropathy) most do not explain this to the patient as ...Read more
"tumor" literally translates as "mass", so even a fresh bruise could be called a "tumor". Doctors use the term "neoplasm" (tranlates literally as new growth) to describe tumors that are abnormal growths of cells. These may be benign or malignant; "malignant" = cancer. In everyday usage, we use "tumor" ...Read more
