What happens during a thyroid ultrasound?
an imaging technique used for diagnosing suspected thyroid disease. It uses harmless, high-frequency sound waves to form an image. The sound waves are reflected by thyroid tissue to form a picture of internal structures.
Why are the reasons for biopsy of cold spot thyroid scan results?
Thyroid cold spots are areas of decreased radionuclidic uptake, meaning that particular area of the thyroid is not metabolizing iodine. These finding are consistent with cysts, hypothyroidism, benign growths, inflammation, or malignancy. In addition to a scan, an uptake is often performed. This is done by counting the activity of the radioactive iodine (RAI) with a gamma probe, administering the RAI (commonly in pill form), and then positioning the patient about 8cm from the probe and counting activity over the thyroid commonly at 6 and 24 hours post RAI administration. This is helpful in determining if the thyroid is hypo, hyper, or normal (euthyroid). Uptake percentages relative to the initial activity are considered normal within the ranges of 10-30% respectively. Thyroid inflammtion can mimic the uptake values of hypothyroidism. In addition, the patient should not have any study using RAI if they have a study requiring the use of Iodine contrast (eg contrast enhanced CT), take multivitamins containing iodine, have recently taken cold medicine containing iodine or antihistimines including diet pills, or if they are on a special diet containing kelp or seeweed tablets. In patients with known hypothyroidism, thyroid suppressive medication (eg Synthyroid) should be discontinued for 2-6wks prior to RAI administration. Back to the scan... A single cold spot is malignant in about 10-20% of cases. Therefore, a biopsy is helpful for providing a differential diagnosis using laboratory histology.
What does focal area of uptake mean?
Focal area of uptake refers to a concentrated accumulation of a substance, typically seen on medical imaging studies like PET scans. It can indicate an area of increased metabolic activity or abnormality, such as a tumor or infection. Further evaluation is often needed to determine the cause of the focal area of uptake.
What is the gland in the neck area called?
The thyroid gland .
Is Thyroid disease a disease?
Seeing as the thyroid (thyroid gland) is not a disease but one of the endocrine glands located in our body (specifically in the neck area below the thyroid cartilage). Then no, you cannot "contact" a thyroid from anyone. Since normally, we are all supposed to have a thyroid gland. Well if you meant to say Typhoid fever, then yes, it is indeed a communicable disease.
What is increased uptake in medical terms?
Increased uptake in medical terms refers to an increase in the absorption or utilization of a substance by the body. This can refer to the uptake of nutrients, medications, or other substances that are essential for health and functioning.
What is membrane infolding?
Membrane infolding is a process in which the cell membrane folds in on itself, creating internal compartments or structures within the cell. This folding increases the surface area of the membrane, allowing for more efficient transport of molecules and signaling within the cell. It is a common phenomenon in cells to increase membrane surface area for various functions such as nutrient uptake or organelle formation.
What is a hypodense nodule?
Hypodensity in the brain means that in an area there is less density than other areas of the brain. Instead of brain tissue, there is fat. There are different causes, and a doctor needs to determine it through additional testing.
Is as cell surface area increases cell volume increases faster true?
Yes, as cell surface area increases, the cell volume increases at a faster rate. This is because the surface area to volume ratio decreases as the cell grows larger, which can affect the efficiency of nutrient uptake and waste removal within the cell.
Is hypothyroidism infectious or contagious?
Seeing as the thyroid (thyroid gland) is not a disease but one of the endocrine glands located in our body (specifically in the neck area below the thyroid cartilage). Then no, you cannot "contact" a thyroid from anyone. Since normally, we are all supposed to have a thyroid gland. Well if you meant to say Typhoid fever, then yes, it is indeed a communicable disease.
What is focal uptake on a bone scan?
There is a particular area of bone that is much more metabolically active than the bone in the rest of the body.
What zone of a root tip increases the surface area for water and dissolved mineral uptake?
The zone of a root tip that increases surface area for water and mineral uptake is the root cap region, specifically the zone of maturation or elongation where root hairs are formed. Root hairs are small, finger-like projections that significantly increase the root's surface area for absorption.
