How Do You Differentiate Between Tumor Or Clot On A Ct Scan
Dye: Xray contrast or dye. Helps differentiate types of tissues. See radiologyinfo.Org. ...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
Dad recently diagnosis w mod.Differentiated keratinizing squam.Cell ca his e.N.T dr awaiting on aurthorization from ins.For CT scan prior sx, should we wait?
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.
Grade 1 is a good:
Sign, but nothing is guaranteed. Need to further understand the liver lesion as well.
Work with the medical team to put together the best treatment plan for the individual patient situation. ...Read more
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 more
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 more
It may: But a contrast enhanced study would be more sensitive. If concerned, see a urologist for full evaluation and diagnostic work-up. Best wishes. ...Read more
A cm is: Roughly a half-inch, so 6.6 is a little more than half that and quite easy to not been seen on ct, and unlikely to be seen on a plain film...And I am speaking of chest. Abdomen or pelvis even easier to miss. ...Read more
Why do some doctors say a cranial CT scan will show all tumors except small ones and other doctors say they won't show them very well?
See: Ct-scan-info.Com and radiologyinfo.Com. Look up head ct. ...Read more
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 more
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 more
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
The substances used: in PET are radioactive tracers that accumulate to varying degrees in sites of metabolic activity. Cancers typically have altered/increased metabolic activity relative to normal organs and tend to take up more of the tracer. The radioactivity is detected by the scanner and forms an image which lacks anatomic detail, so it is superimposed over a CT scan, which provides the necessary detail. ...Read more
Diagnosing rectal ca: Some symptoms may be due to benign conditions and are not necessarily cancer. Pelvic ct scans are routinely used to detect rectal cancers, but small cancers may escape detection. A qualified physician should perform a physical exam and order additional tests, usually a combination of scans, blood tests (including tumor markers), plus colonoscopy. ...Read more
Small low grade mass: Some small low grade tumors that have not incited vasogenic edema could be missed on ct scanning. The addition of IV contrast would improve visualization of some tumors, but ct has limits in resolution when compared to mri. These are not the tumors that cause profound symptoms, frequently these small tumors are found incidentally when patients have scans for other reasons. ...Read more
CT not sensitive: Ct brain is a fast screening exam that is often used in the acute setting such as the emergency room. It is helpful in detecting obvious tumor and mass effect from the tumor. However, it is not sensitive in the detection of small tumor which does not produce mass effect or surrounding brain edema. Mri brain with and without contrast is the best imaging modality for detecting brain tumor. ...Read more
Yes: It will give the indications of a cancerous tumor but a biopsy will be needed. ...Read more
Yes most likely: Yes most likely it will show on a cat scan. ...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
