Are suv on pet scan gamma?

Are suv on pet scan gamma?

SUV...: Suv stands for standardized uptake value. It is used for semi-quantitative analysis on pet scan. It tells the amount of glucose uptake or hypermetabolism of a tumor. ...Read more

Staging (Definition)

Many diseases have specific treatments based on their severity. A disease can have certain criteria to determine their severity and applying this criteria to determine how advanced the disease state is called staging. Most commonly this is applied to cancer, and be determining how far the cancer has spread locally and/or to distant sites a stage of cancer can be ...Read more

Colon surgery:tumor size=2cm.Pathologic staging(pt3, n1b, mx).2/17 lymph nodes show metastatic.Margins of resection free of carcinoma.Need chemotherapy?

Colon surgery:tumor size=2cm.Pathologic staging(pt3, n1b, mx).2/17 lymph nodes show metastatic.Margins of resection free of carcinoma.Need chemotherapy?

Yes: Chemotherapy regimens based on the drug Fluorouracil (5-fu) have been part of the treatment for high-risk stage ii or stage iii colon cancer. Many clinical trials have shown that these regimens improve overall survival primarily by reducing the high risk of recurrence within the first two years after surgery. ...Read more

Do pet scans show lung cancer?

Do pet scans show lung cancer?

Sort of...: The pet scan non-specifically show very metabolically active (consuming lots of energy), and lung cancer and its metastasis fit that category. It is not specific. Benign conditions like sarcoid can also make pet studies glow very brightly as well. Slow growing lung cancer, broncheoalveolar may not be pt avid. ...Read more

Is Full body PET scan or CT scan better for diagnosing Lymphoma? Which uses less radiation?

Is Full body PET scan or CT scan better for diagnosing Lymphoma? Which uses less radiation?

Both: The actual diagnosis of lymphoma requires tissue, usually excisional biopsy of an entire lymph node. Staging to see where other sites of disease could be is done with a combined PET/CT. The staging used to matter more many years ago when they would often give XRT or do surgery, it doesn't matter as much as it used to because almost everybody gets systemic chemotherapy for both Hodkins and non H ...Read more

Can a CT scan see stage 2 colon cancer?

Can a CT scan see stage 2 colon cancer?

Sometimes: Ct imaging can show abnormalities in the colon, but the best test is colonoscopy. This gives a doctor the chance to directly visualize the colon and also biopsy anything suspicious. ...Read more

Lul non small cell hilum region with lymph node involvement on pulmonary artery. Pet scan negative. Please stage.

Lul non small cell hilum region with lymph node involvement on pulmonary artery.  Pet scan negative.  Please stage.

Need more info: To completely stage, would need more information. However, lymph node involvement excluded stage 0 and stage i. If lymph nodes are on the same side as the hilar tumor, the tumor is at least 2 cm from the carina (where trachea divides into r and l main bronchi) and the tumor is 5 cm or smaller, it is stage iia. If tumor is 5-7 cm, and the rest true, it is stage iib. After that, it is complex! ...Read more

How is pet CT scan done?

How is pet CT scan done?

PET/CT scan: You need to fast for 4 hours first, then you will recieve an injection of a small amount of radioactive glucose (i.e. Sugar). Next you will sit in a recliner chair for about 70 minutes to allow the glucose to distribute throughout you. Then you will lie on your back on the pet/ct scanner (a tunnel shaped machine) for 20 minutes. There are no side effects from the test or restrictions afterwards. ...Read more

How do pet scans, mri, ct, and bone/gallium scans differ?

How do pet scans, mri, ct, and bone/gallium scans differ?

Different mechanisms: Mri uses magnetic radiation( no x-ray) for anatomic localization and characterization of different parts of body, water and fat constitution of different tissues.Ct uses x-ray to characterize anatomy of body, better for bone than mr.Pet, bone, gallium scans use radio tracers intravenously.Petglucose metabolism of tumors, gallium (infection/tumor), bone scan for fxs, tumors, infection bone metabolism. ...Read more

Does a normal CT scan exclude pancreatic cancer?

Does a normal CT scan exclude pancreatic cancer?

Not entirely: Ct imaging is useful, but pancreatic cancer can be very difficult to visualize on ct. In fact, even in patients with known pancreatic cancer it's not unheard of for the tumor itself to be poorly or incompletely seen. If there's high suspicion, endoscopy and ultrasound are useful tests. ...Read more

Which modality is better for detecting or confirming metastasis pet scan or bone scan? !

Which modality is better for detecting or confirming metastasis pet scan or bone scan? !

Depends on cancer: Each cancer type has an optimum way to image it, especially with techniques that image physiology, like pet and bone scan, as opposed to techniques that image anatomy, like ct and mri. Pet is best for cancers that use a lot of glucose as an energy source, like lung cancer. Bone scans are best for cancers that disrupt bone, like prostate cancer. ...Read more

My pet scan was highly suspicious for malignancy in rt lung.Now onto Bronchoscope so didn't pet confirm cancer?This cancer isn't curable!

PET scan helps but n: A PET scan can show an abnormality where body cells are overactive. This happens commonly with Cancer and with any Infection or inflammation. So a biopsy is required to make the distinction between Inflammation and Cancer. A bronchoscopy may show the tumor or it may be used to get a biopsy by getting near to the tumor ...Read more

Could a pet scan detect ovarian cancer?

Possibly: If tumor metabolically active will pick up isotope f18 FDG , analog of glucose. Imaging with pet ct will detect abnormality. Most malignant tumors are active, but not all. ...Read more

On a pet scan does a lower SUV uptake meAn less aggressive cancer ? The SUV uptake was 5.2,

On a pet scan does a lower SUV uptake meAn less aggressive cancer ? The SUV uptake was 5.2,

No: SUV has no bearing on the aggressiveness of the cancer. It is a relative measure of the glucose metabolism. In fact, some very aggressive tumors have no FDG uptake at all. Some benign conditions like infection can have high uptake. The standard uptake value depends on many factors like patient body size and serum glucose level and the normal uptake in the tissue surrounding the target lesion. ...Read more

Can hodgkin lymphoma transform to NHL? After 4 cycle of ABVD, PET showed an area with SUV 14. Initial diagnosis was HL IIb, bulky.

Can hodgkin lymphoma transform to NHL? After 4 cycle of ABVD, PET showed an area with SUV 14. Initial diagnosis was HL IIb, bulky.

Yes it can: This change has been reported, so it is entirely possible. But only a biopsy of the new area or the growing lymph node can determine what is going on. Your oncologist should be able to help address this matter for you. Or you can seek a second opinion from another medical oncologist, if you are not totally satisfied with your current oncologist. ...Read more

Computed Tomography (Definition)

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
