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

When the ER doc is doing a CT scan on head to check for tumor and or aneurysm , do they have to use contrast? Or can I get it without contrast?
For the best study: For brain tumors, a ct scan of the head without and with contrast best delineates the tumor. To check for an aneurysm, contrast is needed for the ct-angiogram. If you are concerned about radiation and contrast, and if it is an elective evaluation for brain tumor or aneurysm, you might consider an mri/mra. ...Read moreSee 3 more doctor answers
If theres not masses or cyst how is endo diag above the pelvic area, do to the spot/implants don't show up on imaging if suspected what type of dr remov?
Endometriosis: It sounds to me that you are trying to find out how endometriosis is diagnosed and treated. You are right that there are no good imaging studies for this and the best diagnosis is made by (1) high index of suspicion--pain is cyclic around menses (2) laparoscopic surgery for diagnosis and treatment. A long history of endometriosis also leads to "adhesions" that can only be treated surgically. ...Read more
Hi can doctors tell the difference between a cyst and a tumor on the kidney's just by looking at a CT scan?
Usually: Simple cysts of the kidney are common and most of them can be identified as such by radiologists with certainty. If there's a question, it's often a simple matter to sample the tissue with a needle. Likewise, dangerous tumors won't be mistaken for common cysts. ...Read more
Would mesothelioma show up on a X-ray or ct scan if it were causing chest pain I know MRI is better just wondering if the other 2 would detect it?
Nonstarter question: Though MRI is better at picking up what turn out to be mesotheliomas on the pleura, the only accurate diagnosis occurs by biopsy or cytology - you need to see cells under a microscope to make a diagnosis. Pleural anomalies can cause discomfort (irritation, difficulty breathing, pain with coughing) but whether or not mesothelioma causes pain depends on location, too; & not all chest pain is cancer. ...Read more
Will a CT scan (no contrast) detect cervical cancer if it's stage 2B or above? I realize a CT can't diagnose cervical cancer, I'm just wondering how likely it is that something would show up on a ct.
Not always clear cut: Purely simple, smooth ovarian cysts are considered benign. Cysts with debris, septations or nodules along their walls can be concerning. Sometimes we do follow up ultrasound to see if they grow. If there is enough concern, MRI helps. Correlation with patient age, family history, blood tests and possibly biopsy also help us be sure. ...Read more
Whats the difference between a CT scan of the sinuses and a maxillofacial CT with contrast? Why would i need both?
Not sure: If a physician is trying to determine if you have sinusitis, a cat scan without contrast is all you need. However, if your physician is concerned about something else such as a vascular anomaly or unusual growth in the maxillo-facial region, the radiologist may need to use contrast. Ask the doctor or radiologist to explain why both are needed. What is the diagnosis he wants to make? ...Read more
How will a neurologist know if you had a TIA or not? What are the key things that stand out as a tia? Do they show up on a CT scan or an mri?
History: Tia symptoms are short lived, minutes to hours and should completely resolve in 24 hours. At your age ct and MRI are done to exclude tumor or bleeding. Other conditions that could be present would include migraine which usually has a more gradual presentation than tia. ...Read moreSee 1 more doctor answer
I may have a spleen injury. Do not want a CT scan. No symptoms other than pain. Can ultrasound diagnose the extent of the injury. Thank you?
Not entirely: Generally a ct will evaluate not only the spleen, but the other organs (kidney, adrenal gland, ribs, lung base, pancreas, stomach/ bowel and adjacent retroperitoneum) in the left upper quadrant – the area where you seem to have your discomfort. An us can accurately evaluate the spleen, and the left kidney but may have limitations based on body habitus, rib shadowing, bowel gas – to fully evaluate. ...Read moreSee 1 more doctor answer
Lytic lesion: This is a lesion in which the bone is being destroyed. This is typical for cancers that spread to bone. Such cancers include multiple myeloma, breast, thyroid, lung and kidney. There are a few reasons to seek MRI - best to check with your doc as I would simply be speculating. ...Read more
Does a CT show how much plaque is present in the carotid siphons? Or do I need to do further tests
MRI: Ultrasound has a problem distinguishing one soft tissue (like muscle) from another (like nerves or tendons or fat or skin). So the cremaster muscle is hard to see on US. A (fat-saturated T2 inversion recovery or fat-sat IR) MRI scan stands a better chance of distinguishing the muscle from other types of tissues in the groin. A CT scan has a chance, but it involves radiation, which is best avoided. ...Read more
Which kind of non-invasive test should I do if I wanna know whether my tube is blocked or not? Can a MRI or CT scan give an accurate answer ?
1st have a Sonogram: Endovaginal Sonogram is the best initial evaluation for infertility. It is relatively non invasive as it doesn't penetrate through the skin or mucous membrane. Hysterosalpinography can be performed with Sono or X-ray. I think X-ray is best after doing over 1000 of them. ...Read moreSee 1 more doctor answer
"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
