What Is The Difference Between A Urogram Ct Scan And A Pet Ct Scan
Nuclear study: Ct radiographic examination by itself is usually more detailed with higher resolution utilizing intravenous contrast material to help differentiate soft tissue abnormalities such as lymph nodes from vascular structures. Ct combined with pet, is low resolution but helps define areas of increased radiotracer uptake of isotope f18 fdg, glucose metabolite, by allowing anatomic localization. ...Read moreSee 1 more doctor answer
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
Am i at a higher risk i had an episide of gross hematuria saw 2 different uros all testing cam eback neg two cyystoscopies cytologues renal us CT urogram CT scan nothing was found to explain this. My question is am i now at a highher risk for possible bl
No: You have had all the necessary tests by 2 urologists and nothing was found. Most likely the hematuria was from your prostate.If there was bladder tumor or kidney tumor or renal pelvic tumor the studies you had would have been diagnostic.If hematuria recurs, go back to your urologist.It sounds like you are OK. ...Read moreSee 1 more doctor answer
Several uses: In most cases PET CT scan is used for detecting metatases in the body. It can also be used for brain with mets, primary tumors, and epilepsy. Injection of glucose metabolite F18 FDG goes to malignant lesions that are highly metabolic,. Usually more sensitive for detecting smaller lesions. Used in staging malignancies and following patient's response to chemotherapy and radiation ...Read moreSee 2 more doctor answers
Unlike many imaging: Procedures, whereeach test tries to pay off the cost of the instrument, each pet scan needs to buy a cyclotron produced dose of flurodeoxyglucose. It has a short half life, and it must be paid as well as the scanner. These will always have high cost of production so medical tourism may not work as well as for a procedure or a simple diagnostic study. ...Read moreSee 2 more doctor answers
Have a PET/CT scan tomorrow at 1 pm, its 6:45pm now. I had fried chicken but I peeled the skin off. I had no sides. Will this effect the scan?
Recently,my dad did a PET-CT scan. 4 tumours in liver, 2 are about 1.5cm and 2 less than 1.0 cm. These tumous are from his colon. What to expect?
Treatments available: Case should be discussed on a multi-specialty tumor board. Inoperable liver metastasis may be treated with chemotherapy, radiofrequency ablation, & Radioembolization (performed by Interventional Radiology). Radioembolization combined with chemo has shown to slow progression for colon cancer when disease has progressed following prior treatment with chemotherapy & metastases limited to the liver. ...Read more
Would a PET/CT scan easily show that a person had a hernia even though the pathologist is looking for a cancerous tumor? Would it be noticeable?
I understand that malignant tumors will show high fdg avidity, is it possible for a benign tumor < than 1 CM to show high fdg after a pet/ct scan?
Possible but see MD: Fdg-pet, also known at fludeoxyglucose - positron emission tomography, uses the radiolabelled glucose molecule, which is taken up by metabolic active cells, which can be either benign or malignant. It is used to image the heart, brain, as well as areas of cancer or inflammation. One must put into context the clinical history, history of cancer or evidence of infection. See your md for advice. ...Read moreSee 1 more doctor answer
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
