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.

Does a pet CT scan replace a colonoscopy?

Does a pet CT scan replace a colonoscopy?

How much does it cost me to get a pet CT scan in india?

How much does it cost me to get a pet CT scan in india?

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 more

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?

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?

Possibly: A hernia is where part of the intestine protrudes through a defect in the wall that usually holds it in place. If the hernia has reduced itself (gone back into the place where it belongs), then the CT/PET scan will likely not show the hernia's presence. ...Read more

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?

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 more

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
