Can a cat scan determine if a tumor is cancerous or do you have to have a biopsy?
A CT scan can provide detailed images of a tumor and help identify characteristics that may suggest whether it is cancerous, but it cannot definitively determine if a tumor is malignant. A biopsy is necessary to obtain a sample of the tumor tissue for microscopic examination, which can confirm the presence of cancer cells. Therefore, while a CT scan can aid in diagnosis, a biopsy is required for a conclusive determination.

Why is a biopsy given after a pet scan?

What does a normal chest ct scan with contrast look like?
A normal chest CT scan with contrast typically shows clear lung fields, with well-defined vascular structures and no evidence of masses, nodules, or significant lung disease. The mediastinum appears unremarkable, with normal heart size and contours, and no enlarged lymph nodes. The pleura should be smooth, and there should be no signs of fluid accumulation or abnormal pleural thickening. Overall, the scan would reveal a healthy thoracic cavity with no abnormalities.
What does hypermetabolic mean in regards to a node on a PET scan?
Hypermetabolic refers to an area that shows increased metabolic activity on a PET scan, typically indicated by higher uptake of the radioactive tracer used in the imaging. In the context of a lymph node, this can suggest the presence of conditions such as infection, inflammation, or malignancy, as cancerous tissues often exhibit elevated metabolic rates. Therefore, a hypermetabolic node may warrant further investigation to determine the underlying cause.

What is an adrenal gland scan?
An adrenal gland scan is a type of imaging test that uses radioactive tracer to visualize the adrenal glands, which are located on top of each kidney. This scan can help diagnose conditions such as tumors, hyperfunction, or other abnormalities in the adrenal glands.
Can you perform ct scan of thyroid gland?
If there is a need to scan the thyroid gland, most of the time it can be done using an ultrasound scan. If further testing is needed, sometimes a doctor will order what's called a thyroid scan. A thyroid scan is a picture of the thyroid gland. This is taken after a small dose of a radioactive isotope, that is normally absorbed by the thyroid cells, has been injected or swallowed. This helps a physician determine if a growth on the thyroid is an active part of the thyroid tissue or not.
What aftercare is required for a salivary gland scan?

What is a salivary gland scan?
A salivary gland scan is a nuclear medicine test that examines the uptake and secretion in the salivary glands of a radioactively labeled marker substance. The pattern of uptake and secretion shows if these glands are functioning normally.

Is there a cure for hyperparathyroidism?
yes How? By adding a simple but vital supplement to your diet: IodineThe above answer is absolutely incorrect. Yes, often times there is a "cure" for hyperparathyroidism, however the only "cure" is to identify which one or more of the parathyroid glands (located in your neck behind the thyroid gland), is enlarged, and then having it removed.Identification of the enlarged parathyroid gland(s) is done through a Sestemibi scan. Unfortunately, since these scans aren't done often and when done, are typically misread or performed incorrectly, results come back negative in many patients and the disease is misdiagnosed.

Isoechoic means same texture as surrounding tissue on an Ultrasound. Lucent or Sonolucent means abscence of echoes surrounding the area. The thyroid gland can have areas that appear to be a "Halo" with normal tissue inside. After a biopsy or nuclear scan it may be diagnosed as an Ademona or Cancerous. They can be Euthyroid ( not effecting thyroid hormone levels) or hyperfunctioning (secreting more hormones than normal) -this information is based on studies of the Human Thyroid Gland.
