Ultrasound system: A console, or a portable system, which includes a monitor and a transducer, and utilizes ultrasound to image body tissues. To image the thyroid and parathyroid glands and neck lymph nodes; also, to guide diagnostic fine needle aspiration [4] or therapeutic ethanol injection to these organs. [5]
It is iso-echogenic to the thyroid gland with no definite connection to the thyroid gland. b Transverse colour Doppler ultrasound shows significant increase in vascularity. c Axial enhanced neck CT scan at the level of thyroid cartilage demonstrates midline infrahyoid hyperdense soft tissue mass (white arrow) embedded within the strap muscle.

Most commonly an ultrasound is performed to confirm the presence of a nodule, and assess the status of the whole gland. Measurement of thyroid stimulating hormone and anti-thyroid antibodies will help decide if there is a functional thyroid disease such as Hashimoto's thyroiditis present, a known cause of a benign nodular goitre. [4]
Theoretically, the hyperfunctioning parathyroid gland will take up more of the Tc99m-sestamibi, and will show up 'brighter' than the other normal parathyroid glands on the gamma camera pictures, especially because of the internal biofeedback loop within the body with calcium inherently feeding back to calcium-receptors and inhibiting ...
Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.
Preoperative contrasted CT scans of the patient, showing multiple bilateral kidney tumors, with diameters ranging between 1 and 5 cm. Radiologically, most of the tumors have malignant characteristics due to their hypervascularity and radiopaque enhancement.
Elephant diets range from grasses and leaves to shrubs and fruits to roots, depending on the time of year and where they live. When conditions are particularly dry, elephants increase their ...
The patient swallows a radioisotope of iodine in the form of capsule or fluid, and the absorption (uptake) of this radiotracer by the thyroid is studied after 4–6 hours and after 24 hours with the aid of a scintillation counter. The dose is typically 0.15–0.37 MBq (4–10 μCi) of 131 I iodide, or 3.7–7.4 MBq (100–200 μCi) of 123 I ...
